Activated carbon

Activated Carbon (also known as Activated Charcoal or simply AC) filters are used for the removal of colour, odour and taste from drinking water.


Bromine, chlorine, fluorine and iodine belong to a family of elements known as halogens. Halogens share similar properties like disinfection and bleaching.


Chlorination is a powerful water disinfection technology. It is effective against almost all microorganisms including bacteria, viruses and protozoa.

Crossflow filtration

It is the membrane process utilized in RO, UF and microfiltration units. It uses pressure to force water against a fine membrane to filter water.


This article provides an overview of scale formation chemistry and discusses a hydrogen-based ion exchange process known as decarbonisation.

Deionization DI

DI results in pure water that is very reactive and not suitable for drinking. It is kept in contained environments to avoid exposure to air or other chemicals.

Depth cartridge filters

Depth cartridge filters are specially designed to offer better sediment prefiltration distribution across the cartridge surface.


Water disinfection means the removal, deactivation or killing of bacteria, viruses and other harmful microorganisms present in water supply.


Electrodialysis is an ion exchange process, to reduce limescale, that uses electrical current to separate ions based on their charge.


Iodine is a halogen element used for water disinfection. It can protect against exposure to Giardia (a parasite that cause gastrointestinal illnesses).

Ion exchange

Ion exchange refers to the process of water softening or the exchange of sodium ions for calcium and magnesium ions in order to remove hardness.

Magnetic devices

Magnetic water treatment (MWT) claims that if hard water is passed through a strong magnetic field, the level of limescale formation drops.


Microfiltration (MF) is a membrane separation process that filters out colloidal and suspended particles in the range of 0.1 to 10 microns.

Nanofiltration NF

NF filters out large molecules, salts and heavy metals in the 0.001-0.01 micron range (viruses and bacteria are about 0.01 and 1 micron).

Multi media

A multi-media filter, or depth filter, is a simple water filtration technology that utilizes layers of sand, gravel, garnet and coal to achieve fine filtration.

Neutralizing filters

In a neutralizing filter an alkaline material (usually lime) is added to balance acidity. This raises the pH of water to be close to neutrality over time.


It is a form of disinfection, effective against bacteria, algae, mold and viruses and removes heavy metals and taste from water.

Pleated filters

Pleated filters are designed to have a large surface area of sediment filtration in a small, compact design.


Oxidizing filters oxidize iron and manganese ions in the water by utilizing oxygen from air. An aeration system increases the level of oxygen.

Precoat filters

Precoat filters combine sediment and carbon filtration in one cartridge with six times more filtering surface area than other systems of similar size.
