Desalination Plants with a capacity of 100.000 m³/day provide the population with drinking water via central networks. Plants with capacities of some 500 litres to some10.000 m³/day secure the supply at decentralized sites without being connected to public supply mains. Many hotels and also local industry are heavily based on such systems. The forum is concentrated on Mini & Mikro desalination systems. The simple and robust handling of such plants will be the key subject. Most often energy consumption of small systems is not monitored. The forum will have a close look at this area. Availability is the key in this business. Ordering tankers with water is always an expensive and unexpected situation.

Membrantechnik in Wasserwerken (05.05.2022)

Beschreibung des Themas:

Betreiber, Aufsichtsbehörden, Planungsbüros, Anlagenbauer und Forschungseinrichtungen im Umfeld von Wasserwerken

Motivation für die Veranstaltung:

Eine immer größer werdende Menge von analytisch nachweisbaren Stoffen werden im Rohwasser der Trinkwasserversorgung analysiert. Einfluß und Wirkung einiger dieser Stoffe sind noch unerforscht oder gänzlich unbekannt. Andere Stoffe sind als Störstoffe identifiziert und werden beobachtet oder teilweise bereits in der Trinkwasseraufbereitung abgeschieden. Die wachsende Zahl der verschiedenen technologischen Ansätze und Umsetzungsformen zeigt die aktuelle Bandbreite der Herangehensweisen und Lösungsansätzen. Ein vereinheitlichtes Vorgehensmodell ist noch nicht sichtbar, Falllösungen bestimmen die Landschaft.

Zielsetzung der Veranstaltung:

Die Vorstellung der aktuellen Vorgehensweisen und Konzepte als auch technischen Vorschläge und umgesetzten Lösungen werden den Teilnehmern einen aktuellen Überblick zum Stand der Forschung und Technik ermöglichen. Der Erfahrungsaustausch in Form von offenen Gesprächen und Diskussionen zu den aktuellen Fragestellungen ermöglicht es den Teilnehmern für Ihre Fragestellungen Beispiele und Lösungen näher zu betrachten und den fachlichen Austausch im Dialog zu führen.

Gewonnene Erkenntnisse aus durchgeführten Veranstaltungen:

Nach der erfolgreichen Durchführung unserer deutschlandweiten ersten Seminare in Kooperation mit dem DMGT und der Universität Duisburg Essen zu diesem Thema im Juni 2017 und 2019 wurden Grundlagenfragestellungen zu rechtlichen Rahmenbedingungen zum Umgang mit Konzentratströmen in Wasserwerken formuliert und mündeten in Forschungsaufgaben. Der fachliche Austausch von Aufsichtsbehörden wurde initiiert und intensiviert.

Vorträge:

Vortrag 1: H2U aqua.plan.Ing., Frank Urban

Vortrag 2: IWW, Anil Gaba

Vortrag 3: NX Filtration, Erik Roessink

Vortrag 4: OOWV, Kerstin Krömer


Target group of the event:

Operators, supervisory authorities, planning offices, plant constructors and research institutions in the field of raw material extraction and the environment.

Motivation for the event:

An ever increasing demand for raw materials, both salts, minerals and carbon are present in the direct or indirect environment of desalination plants. The exclusive extraction of drinking water from brackish water and seawater is increasingly being combined with the extraction of raw materials, also in view of the efficiency of these plants. The growing number of different technological approaches and forms of implementation shows the current range of approaches and solutions. A unified predictive model is not yet visible, case solutions determine the landscape internationally.

Objective of the event:

The presentation of current approaches and concepts as well as technical proposals and implemented solutions will provide participants with an up-to-date overview of the state of research and technology. The exchange of experience in the form of open talks and discussions on current issues will enable participants to take a closer look at examples and solutions for their questions and to conduct the technical exchange in dialogue.

Lessons learned from events held:

After the successful implementation of our first nationwide seminars on this topic in June 2017 and 2019, basic questions on the legal framework for dealing with concentrate flows in waterworks were formulated and resulted in research tasks. The professional exchange of supervisory authorities was initiated and intensified.

Lecture 1: Material recovery from spent spiral wound modules. (MemRe, Claus Mertes)

Lecture 2: Pharmaceutical salt extraction from standard seawater desalination plants (K-UTECH, Florian Huber)

Lecture 3: comes



The transformation of energy supply from carbon to alternative forms of energy entails many innovations. The goal itself is beyond question, but the way to get there raises many questions.

The production of hydrogen starts with energy and water, and the demands on this water are high. The provision of this basic material from saline water expands the places of use and makes the places of application more flexible.

The choice of the appropriate desalination technology is determined by the required purity, the variability of the raw water source as well as the adaptability of the required quantity.

Other factors are the available energy source and the flexibility from standstill, stand-by to full-load operation. Each technology has its own practical, operational and theoretical limitations. This also applies to the desalination of water in connection with hydrogen production.


In the context of the lectures, this area of tension will be illuminated and possible solution variants from the point of view of both the hydrogen industry and the desalination industry will be shown.

Eine immer größer werdende Menge von analytisch nachweisbaren Stoffen werden im Rohwasser der Trinkwasserversorgung analysiert. Einfluß und Wirkung einiger dieser Stoffe sind noch unerforscht oder gänzlich unbekannt. Andere Stoffe sind als Störstoffe identifiziert und werden beobachtet oder teilweise bereits in der Trinkwasseraufbereitung abgeschieden.

Die wachsende Zahl der verschiedenen technologischen Ansätze und Umsetzungsformen zeigt die aktuelle Bandbreite der Herangehensweisen und Lösungsansätzen. Ein vereinheitlichtes Vorgehensmodell ist noch nicht sichtbar, Falllösungen bestimmen die Landschaft.

Im Rahmen dieser Veranstaltung wird der aktuelle Stand der Vorgehensweisen und Konzepte als auch technischen Vorschläge und umgesetzten Lösungen den Teilnehmern einen aktuellen Überblick zum Stand der Forschung und Technik ermöglichen. Der Erfahrungsaustausch in Form von offenen Gesprächen und Diskussionen zu den aktuellen Fragestellungen ermöglicht es den Teilnehmern für Ihre Fragestellungen Beispiele und Lösungen näher zu betrachten und den fachlichen Austausch im Dialog zu führen.:

Nach der erfolgreichen Durchführung unseres deutschlandweiten ersten Seminares in Kooperation mit dem DMGT und der Universität Duisburg Essen zu diesem Thema im Juni 2017 wurden Grundlagenfragestellungen zu rechtlichen Rahmenbedingungen zum Umgang mit Konzentratströmen in Wasserwerken formuliert und mündeten in Forschungsaufgaben. Der fachliche Austausch von Aufsichtsbehörden wurde initiiert und intensiviert.

Wir freuen uns in enger Zusammenarbeit mit der DGMT, Universität Duisburg Essen und weiteren Organisationen gemeinsam diesen Termin zum Gedankenaustausch anbieten zu können.

Introduction to Water Desalination: Technology-Markets, Environment

This Seminar addresses mainly representatives of politics, business and science, who want to acquire elementary technical and economical information about this important and rapidly growing branch.

In the framework of selected speeches international-ly recognised experts will present an overview on the most relevant desalination technologies and their application. Furthermore they will present markets, potentials and trends in research and development.


This Seminar will highlight the global actual situ-ation reviewing all existing desalination plants driven by nuclear power, point out necessities to ensure all safety aspects, show the latest developments of both fields of interest applica-ble for best solutions. At the end of the presen-tations the speakers will answer all your ques-tions and discuss with you.

Desalination driven by nuclear power is an op-tion to separate salty water into fresh water and brine. Nuclear power can provide tempera-tures and heat in a reasonable range for thermal processes and electricity for membrane pro-cesses. So called either process integrated (thermal) and project integrated (electricity) co-generation plants.


Desalination powered by solar energy is the oldest method nature does practice at all. But their are a lot of other possi-bilities to desalinate water with renew-able energies.

In this Seminar state of the Art devel-opments in renewable powered Desali-nation will be demonstrated. Partici-pants will have the chance to get an outlook into the existing and upcoming developments.

Desalination with small and mobile systems

Having water on time in place is a challenge. Building pipe lines is a limited option, depending on the distance water needs to be transported. Also having a plant not being operated due to sufficient rain fall looks like an investment not being in use.

All this gives mobile desalination plants an option to fill this gaps. And today amobile desalination plant can be in a pocket of a trouser producing less than 1 litre in an hours time up tp a desalination Tanker providing 70.000 m³/d.

Small desalination plants are today the majority of all installations found all around the world. Looking into the compo-nents used they have to be very robust and repayable at a reasonable price.

Membrane development is going very fast. New materials are developed, new composites are introduced, new concepts are published.

This Seminar will give the overview of what is coming next in RO Membrane development and sales to get the participants up to speed in one go.

Since the first RO plant has been erected the development of membranes has continuously proceeded further. The quality of membranes has been improved and the membrane technol-ogy diversified. Nowadays RO Membranes are pushed to the limits and new material and manufacturing developments opening and ab-sorbing old and new markets. At the end of the presentations the speakers will answer all your questions and discuss with you.

The Seminar gives a compact vendors overview about the existing membranes for mem-brane plants and the different fields of applica-tion in Europe and the Arabian countries. Latest R&D developments will be presented. In 2018 this is the first advanced seminar. This time our partner and sponsor of the seminar is Lanxess.

This seminar is primarily aimed at representa-tives of companies and universities as well as representatives of research and those who want to acquire this special know-how.

Future Desalination Technologies

Everybody is familiar with MSF, MED, RO, NF, UF. Some might have been in contact with MD and FO. But who knows how this works and who knows what comes next after MD and FO. DME has based on its know-how of desalination technology gath-ered a group of new and interesting tech-nologies being presented by inventors, own-ers of patents and researchers showing where we will go in desalination in the fu-ture. As we all know new and good ideas in desalination are getting more and more needed DME is very proud having gathered this group of people coming and showing a very new way of thinking how to desalinate brackish and seawater in the future. In order to set your expectations you should NOT think of this event to be a shopping area for your company but an illustration of what comes up next; but you may find interesting contacts and people you may stay in contact with in the future.

Membrane distillation (MD) is an emerging technology which attracted a lot of interest in the last years but did not commercialise on large scale until today. A significant increase of research activities is visible due to rising number of publications and conference shares and a few companies already focus their business on this technology. A number of pilot units are already in field operation.

The intention of the seminar is to provide a compre-hensive overview on MD from theoretical background to practical applications and to bring together re-searchers, MD system and component producers and companies who are potential applicants for MD tech-nology.

The seminar will provide details on the physics behind MD and show the advantages and limitations of the process. Possibilities for process optimization will be shown as well as the impact of membrane parameters. Practical results from the lab and from the field will be provided and potential applications for industrial use of MD will be discussed.

Membranes in Water Processing incl. Zero Liquid Discharge

Since the first RO plant has been erected the development of membranes has continuously proceeded further. The quality of membranes has been improved and the membrane technology diversified. Nowadays Micro-, Nano-, Ultrafiltration and Reverse Osmosis are as common and Mem-brane Distillation is on its way to fill the gab of thermal and membrane processes.

Material flow treatment and the production of raw material out of sea- or brackish water can be implemented by means of membranes as well as by ZLD.

During the desalination process, seawater will be concentrated as long as there is salty mud left only. Briefly speaking: ZLD helps to protect the environment and to save resources and costs. And beside of this crude materials may be pro-duced!

Since many years mankind is facing the problem of water scarcity all over the world. Since many years the industry is looking for appropriate solutions.

Appropriate solution means a tailor-made solution for a particular situation. Desalination markets exist in many regions of the world: the Middle East, Africa, the Caribbean and even Europe people in these countries and on these continents are suffering from water scarcity. But even if these areas face the same problem, the conditions are always different. The infrastructural as well as environmental conditions change from country to country. For this reason it is important to know the various local conditions in order to offer the right technical solution.

In the frame of the Saudi Water and Power Forum (SWPF) which will take place from December 1st to 3rd, 2013 in the Hotel Hilton in Jeddah DME becomes an official content partner and "Key Solutions for Key in Markets" in Jeddah.

Experts of the desalination industry give an overview about the different desalination markets. They talk about their experiences in the Middle East and Africa, about parameters like energy supply, costs and environmental conditions etc. which have to be taken into consideration in order clients demands.

During the last years the combination of desali-nation and renewable energies became more and more important. Various systems have been de-veloped and are in duty nowadays.

Such systems show their advantage in saving transport and distribution networks especially in decentralized implementations.

Zero Liquid Discharge (ZLD) – save Environment and produce crude Materials! ZLD is a more and more important key word in desalination and a new means to help not only to save resources but to produce and to recover crude materials.How does it work? By applying the ZLD process the huge quantity of fresh water needed in desali-nation plants will be reduced and proportionally will be the brine. During the desalination pro-cess, seawater will be concentrated as long as there is salty mud left only.Briefly speaking: ZLD helps to protect the environment and to save resources and costs and beside this crude mate-rials may be produced!This seminar conveys basic know-how in physics and its limitations with regard to ZLD. It shows the concept of ZLD, the already existing state-of-the-art technology as well as research programs, supported by experience reports of renowned companies.

The energy consumption of desalination plants   in general is very high and therefore energy is one of the biggest cost factor in desalination plants. How can such costs be reduced?

The key word is “Energy Recovery - Energy Saving”!    

Energy Recovery is used in RO plants as well as in thermal plants.  During the last years systems of energy recovery have been modernised. The latest developments include the use of new and alternative materials as well as new technologies of pumps, valves and steering components.

This seminar gives an overview about the today’s commercially available Energy Recovery Systems. The latest innovations will be presented, apt for various plant sizes.

Material flow treatment and the production of raw material out of sea- or brackish water can be implemented by means of membranes.
The DME Seminar S-005-2013 Membranes used in Desalination Plants gives a compact vendor’s over-view about the existing membranes for mem-brane plants as well as about membrane distilla-tion and the different fields of application in Eu-rope and the Arabian countries. Latest R&D de-velopments will be presented.

Designing a desalination plant is a tough chal-lenge and requires technical knowledge and know-how. In order to reduce cost it is im-portant to know the conception of causal rela-tion between the right pre- and post-treatment of water, the implementation of intake systems and pumps and the required result which means potable water.

This seminar gives you a guideline of how to start your conception of a desalination plant. It leads you along the water flow through the plant and shows the right steps of treating water.

Desalination Plants with a capacity of 100.000 m³/day provide the population with drinking wa-ter via central networks. Plants with capacities of some 100 litres to some 500 m³/day secure the supply at decentralized sites without being con-nected to public supply mains. Many hotels and also local industry are heavily based on such sys-tems. The seminar is concentrated on decentral-ized and stand-alone desalination systems. The simple and robust handling of such plants will be the key subject. Most often energy consumption of small systems is not monitored. The seminar will have a close look at this area. Availability is the key in this business. Ordering tankers with water is always an expensive and unexpected situation. The seminar also points out how the independent energy supply of these systems se-cure the long-term water supply at decentralized sites, stressing the importance of such small plants.

The Workshop will feature 4 days of full class lectures,   discussions, calculations case studies and a field trip. After a successful exam DME will hand over its certificate to the student. The workshop will be held in English language by renowned experts who will report on achievements, latest developments and solutions in the field of modern membrane water desalination.
