01What is being requested

PWN Waterleidingbedrijf Noord-Holland and affiliated water companies are ordering an ATMP- and phosphate-free anti-scalant for use in their membrane technology (ultrafiltration, nanofiltration, and hyperfiltration). The contract is aimed at the regional water companies PWN, Oasen, Vitens, and WMD in various Dutch NUTS areas. There is only one lot, without public announcement and with an unspecified duration, aimed at preventing membrane fouling. This tender is of interest to small to medium-sized chemical suppliers with a local presence and experience in water treatment additives.

At the drinking water production sites of the drinking water companies PWN, Oasen, Vitens, and WMD, membrane technology (Ultrafiltration, Nano- and/or Hyperfiltration via reverse osmosis) is applied in the purification process. At other drinking water companies, there are plans to investigate whether membrane technology can be deployed for drinking water production in the future. <br><br>To prevent membrane clogging due to fouling / scaling, anti-scalant is dosed into the influent. The risk of fouling (biomass and/or scaling) is that the membranes clog, production is reduced, and ultimately
