We provide both mesh and bar screening machines (Geiger®, Passavant® for open-channel and tunnelled intakes/vent caps) as well as our Johnson Screens/JOIS™ passive screening system for offshore/submerged water extraction for medium to small applications) to efficiently free the seawater that is subsequently desalinated from debris. In this way we cater for a front-of-the pipe, highest process efficiency on subsequent membrane systems.
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.
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.
