Recently Hatenboer-Water supplied and commissioned an Industrial Demitec Reverse Osmosis installation for the desalination of groundwater at Cargill in Amsterdam.
Cargill already uses a reverse osmosis for desalination of drinking water for boiler feed water. Together with a.o. Hatenboer-Water, Cargill had done a study to see if it was possible to save costs on (drinking) water use. One of the options that were explored what the use of desalinated ground water as feed for the already existing reverse osmosis.
This study showed that that option was profitable and the procedures necessary for acquiring the permits was started.
Once Cargill received the permits, they granted Hatenboer-Water the order for the turn-key delivery of the new Demitec Reverse Osmosis installation.
This installation comprises two desalination streets with a product water capacity of 20 m3 per hour each. The feed water is pumped free of oxygen from two new drilled wells to the treatment plant. By keeping the water free of oxygen (anaerobic) less fouling of the membranes occurs and limited pre-treatment is required. After the desalination, redundant iron is filtered and the product water is neutralized in a calcium carbonate filter to prevent corrosion of the piping in the Cargill plant.
To prevent any fouling during storage, the product water is disinfected by a medium pressure Demitec-UV system. Demitec-UV is a product that is manufactured by Hatenboer-Water based on our years of experience as an industrial and maritime UV-dealer.
The installation is controlled completely automatically and is monitored from a distant control room.
The installation is one in a recent series of industrial Demitec water treatment plants delivered by Hatenboer-Water world wide. For more information about this, or one of the other recent projects, please contact our sales department at info@hatenboer-water.com or call +31 (0)10 - 409 12 00.
