SEDIMENT, PRE-CARBON, UF MEMBRANE AND MINERAL
The URSA Essential Water Systems is recommended whenever it is necessary to improve the chemical and organoleptic characteristics of the water used onboard ships. The unit is installed on the potable water inlet pipe, ensuring that tap water for drinking and galley use tastes great. This filtration system has been specifically designed to solve the common problems of water quality by removing impurities found in water stored in steel tanks and significantly improving taste and odour. The entire system comprises 4 stages of water filtration, performed by 4 individual cartridges, following a prefiltration unit.
