CWC is Africa's most experienced manufacturer of pre-engineered and custom-built reverse osmosis systems for the treatment of residential, commercial and industrial water supplies.

Seawater Desalination

CWC Seawater Desalination

Seawater desalinators can be used on both seawater and highly brackish water supplies to render water suitable for drinking, process or high purity Reverse Osmosis system feed water. Specifications given are for our more commonly requested systems.


CWC Ultrafiltration

CWC has developed a range of compact, easy-to-use ultrafiltration (UF) systems for the pre-treatment of water supplies high in suspended solids and turbidity. Our UF systems are ideal for use at game lodges, farms and other installations where river or dam water is used to provide water for drinking, laundry and general hospitality uses.

Ultraviolet Disinfection

CWC Ultraviolet Disinfection

Ultraviolet (UV) is a non-chemical process used to disinfect air and water. Ultraviolet is popular in industries where the addition of taste altering chemicals is problematic. CWC's potable and process water UV lamps transmit UV-C light and are designed to produce 30 microwatt seconds per square centimetre of ultraviolet light.

Water Softeners

CWC Water Softeners

Water is considered 'hard' when it has excessive levels of calcium and magnesium dissolved in it. The most commonly used equipment for the treatment of hard water is an ion exchange water softener which reduces hardness in water by removing the calcium and magnesium ions in the water and replacing them with sodium ions.
