Evoqua Protegra CS RO
water treatment system

Reverse osmosis water treatment system with deionization modules

Pure water of different quality and in different volumes is extremely necessary to perform a wide range of applied tasks in laboratory practice, medicine and industry. The systems of the Protegra CS RO model range make it possible to obtain clean water in an environmentally safe way, by reverse osmosis and deionization of feed water. Water purified by reverse osmosis can be used in a whole range of laboratory operations: for washing laboratory glassware, as feed water for autoclaves, in climate chambers and for systems that use highly purified water.

A typical application of the system is as a centralized water conditioning plant in a building, supplemented by a closed pipeline network.

• Feedwater conditioning for systems of obtaining
of ultrapure water
• General chemistry
• Liquid preparation for laboratory washers
• Feed water for autoclaves and climate chambers
• Preparation of buffer solutions
