Screening and straining
These two terms refer to the same function - that is of water passing through small bars or small holes in order to retain any matter whose size is greater than the area the water is passing through ...
Clarification
Clarification is a process whereby liquid is separated from solid matter. Solids settle due to the pull of gravity. The clarification stage is usually preceded by coagulation and flocculation ...
Granular Media Pressure Filtration
Granular media is contained within a pressure vessel, typically GRP or coated steel. Water enters the top of the vessel and flows downwards through the bed of media, exiting through a collector system at the base. Contaminants are removed by straining and/or adsorption depending on the chosen media.
Membrane filtration, microfiltration, ultrafiltration, reverse osmosis
The growing importance of membranes in the water treatment process is due to various factors ...
Softening
The high water hardness levels found in some water pose practical problems for both domestic and industrial customers.
Deionization / Demineralization
Deionization is based on ion exchange technology and removes dissolved minerals and salts from water, as well as some dissolved organics...
Continuous Electro-Deionization (CEDI)
Continuous Electro-Deionization (CEDi) is the latest generation of ion exchange technology. This continuous process produces high purity water without the need for regenerant chemicals.
