Water Terminology

Activated Carbon Filters

Activated Carbon, manufactured from burnt coconut shells, is used to remove tastes and smells, as well as residual chlorine from drinking water supplies, industrial process water and reverse osmosis pre-treatment. To a lesser degree, activated carbon also removes organic colour, and in conjunction with the filter under-bedding used, will provide a low level of suspended solids filtration.

Cartridge Filters and Strainers

For point-of-use filtration, reverse osmosis pre-treatment and filtration applications needing extremely low levels of suspended solids, cartridge filters provide a cost-effective way to treat a number of water problems. Cartridge filter configurations can remove suspended particles, taste & odour, chlorine or scale build-up. Resin based cartridge filter systems can be used to soften or deionize water supplies in limited quantities. Manual or self-cleaning strainers can be used as pre-treatment equipment for the removal of large suspended particles.

Iron Removal Filters

Iron and manganese in groundwater supplies often leads to brown or black staining on laundry, walls or home appliances. It is essential to remove iron from reverse osmosis feed water to prevent extensive membrane fouling. Using a combination of organic manganese greensand and ozone injection, we can actively remove iron, manganese, bacteria and viruses from most water supplies, using the iron removal filter media to provide filtration levels to below 10 microns.

Multimedia Sand Filters

Multimedia Sand Filters are used for the reduction of suspended solids and turbidity in surface and groundwater systems. Ideal for use where conventional sand filters cannot cope with the amount of dirt in the water, multimedia filters boast the ability to filter down to below 5 microns, using less backwash water and operating for longer periods between backwashes.

Reverse Osmosis

CWC manufactures a range of custom-built reverse osmosis systems for tap water, brackish water and seawater supplies. Specifications below are for our more commonly requested systems, but larger units can be constructed on request.

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 below are for our more commonly requested systems.


Consolidated Water Conditioning 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

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 (a good example is the bottled water industry). 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

Water is considered ‘hard’ when it has excessive levels of calcium and magnesium dissolved in it. Hard water can lead to the following water problems:

  • Scale build-up in pipes, resulting in decreased flow rates.
  • Scale build-up on heating and cooling systems, leading to increased electricity costs and breakdowns.
  • White film on glass surfaces and staining on water taps.
  • Increased laundry costs due to hard water reacting with soap and laundry detergents.
