Reverse Osmosis

Kalsep’s reverse osmosis systems utilise thin-film wound composite membranes, characterised by a remarkably high rejection rate. The high surface resistance of these membranes ensures a long life cycle, which results in reduced operating costs, even with a high solids concentration in the feed water.

Kalsep designs are based around practical, standardised system components that allow standard designs to be tailored to customer requirements. This provides a customer orientated solution with the assurance of a reliable operating system as well as efficient and cost effective production.

Depending on flow rate required, wall mounted units can be supplied to minimise space requirements and supply from 20 l/hr up to 400 l/hr, with larger skid mounted units providing the higher flow rates required.
