Abstract

Device esp. for lab. use comprises >=1 reverse osmosis stage followed by a finishing stage using ion exchange resins. The reverse osmosis stage reduces the impurities to a level compatible with the efficient use of ion exchange resins for the final stage. The device consists of a box enclosing the reverse osmosis with an inlet for the water under pressure and an outlet for the water charged with the impurities. The purified water leaves at an outlet at the bottom but it needs a further treatment if required for lab. purposes. The box is made of PVC. The outlet is connected to a replaceable cartridge contg. the exchange resins, the recipient being made of transparent polystyrene.
