With generations of experience in providing solutions for water intakes and more than 20 years’ experience in international desalination projects, Passavant-Geiger GmbH is a renowned supplier of intake screening solutions at lowest operational costs (OPEX), smaller footprint (due to reduced channel lengths with the Geiger MultiDisc®) and often surprisingly low total investment costs (CAPEX) thanks to saving space, concrete and scaffolding as well as easier installation/commissioning.
We provide both mesh and bar screening machines (Geiger®, Passavant®) for open-channel and tunneled intakes/vent caps as well as our Johnson Screens/JOIS™ Passive Screening System for offshore/submerged water intakes (for medium to small applications) in order to efficiently clean the subsequently desalinated seawater from debris. In this way we ensure optimal protection and highest process efficiency on subsequent membrane systems.
Low OPEX, lesser total CAPEX, construction time and space savings are the key advantages of our unique screening solutions. The aim is to protect pumps, membranes and condenser tubes from the carry-over of debris. Our customized cathodic corrosion protection systems (with impressed current (ICCP) produced in-house, stand for the best corrosion resistance in seawater.
We have been providing state-of-the art fish and eel protection technology according to the EU-Habitat guideline and to the Clean Water Act 316b under the EPA for decades.
More than 200 desalination plants worldwide are equipped with our machines. Some of our biggest reference plants are located in the Middle East, (mainly Saudi Arabia, Kuwait, the United Arab Emirates, Qatar and Oman), South America and in North Africa (mainly Libya, Tunisia and Algeria), which have some of the biggest desalination capacities worldwide. Our references on MSF, thermal desalination plants and SWRO/BWRO desalination plants are designed for lifetimes of a minimum of 30 years.

Currently, approximately 1% of the world's population is dependent on desalinated water to meet daily needs, but the UN expects that 14% of the world's population will encounter water scarcity by 2025. The number of desalination plants across the world is hence growing rapidly in an attempt to meet freshwater demands. Before seawater can be desalinated it has to be cleared of debris, e.g. sea weed, jelly fish, plastic, sand, etc. to prevent damage to pumps and downstream fine filtration systems and RO membranes.
