WATER &EFFLUENT TREATMENT


believes it is vitally important to our increasingly fragile environment that as much of these metals as possible is recycled so that the waste does not finish up in landfill sites, or far worse, is disposed of illegally.


The company says aqueous wastes should not automatically be incinerated or sent to alandfill site without checking if recovery of any of the contaminants is possible. Doing so could not just help the environment and save valuable metals, it could provide a source of income in these difficult times.

Paint manufacturer enjoys enhanced product consistencyand reduced costs ELGA Process Water,a


Veolia Water Solutions & Technologies company, is helping Pro-Spray Automotive Finishes maintain product


consistency on its latest environmentally friendly refinishing paint.


Due to the need for


bacteria-free, deionised water at the company's Biggleswade head- quarters, Pro-Spray


adopted ELGA Process Water’s proposal for an on-site demineralisation plant that would


produce water of the specified quality as and when needed, elimin- ating the need for IBC handling and storage.

ELGA Process Water suggested that Pro-Spray produce the required deionised water on demand using acombination of reverse osmosis and ion exchange technologies. This would not only be more cost effective than buying IBCs in bulk but would guarantee the consistency of water,and hence repeatable product formulation.


So how does it work? Mains water is delivered into abreak tank and then pumped to a MiniRO™ reverse osmosis plant that removes 95% of dissolved solids and 99% of organic contaminants and bacteria. The permeate from the MiniRO™ is collected in atank and pumped through aUVdisinfection unit, acartridge filter and aservice deionisation cylinder to produce deionised water of better than 0.5µS/cm conductivity.This is delivered to points of use on the manufacturing line via aring


While Pro-Spray’s main objective was to ensure consistent deionised water quality,the company also discovered that the solution saves approx- imately 25p per litre of water compared with the cost of buying IBCs, an outcome that will provide payback in less than two years.
