Zone 2

(Medium hardness/Medium organics)

The quality of water supplies that fall into Zone 2 are the most difficult to predict and quantify as their sources can vary even daily depending on how local water authorities manage their reserves. 

Zone 2

(Medium hardness/Medium organics)

The quality of water supplies that fall into Zone 2 are the most difficult to predict and quantify as their sources can vary even daily depending on how local water authorities manage their reserves. 

Water under this classification can be drawn from a surface supply, an underground source or be a blend of both types, so the design of any water treatment system needs to be based on the worst case scenario.

The quality of potable water from Zone 2 can, therefore, fluctuate from Zone 1 quality to Zone 3 quality or exhibit a mixture of both types, e.g. High hardness and high organics.

Within this zone there exist localised “hot spots” where the organic quality of the source water can be exceptionally variable and typically colloidal in nature. Water treatment systems in these areas will generally require additional forms of pre-treatment, which could include the use of ultra-filtration as a means of reducing the level of colloidal organics.

Haemodialysis

Based on the region or water quality that you have selected, plus the type of application you have chosen, then the solution detailed below is likely to be appropriate.

Please note that even within small geographic areas there can be considerable variation in the quality of the raw water supply; similarly, different projects often have unique requirements in terms of the volume of pure water required, the space available in which plant can be installed and the operating parameters that have to be satisfied. As a result, the solution outlined below should be treated as a guide only.

For an exact specification, or for further details of the proposed solution, please contact one of our water purification specialists.
