New pre treatment system meets environmental
pressures and delivers cost savings.
Williams and Oakey Engineering Co. Ltd is a Precision CNC Machining and Powder Coating company, employing over 60 staff. As with any process line, rinsing is a key factor.
Due to the quality of finish required water quality of < 50 μS/cm is needed at two of the rinse stages to ensure the treated products are suitably rinsed and ready for the next stage of production.
After looking at a number of solutions, a DI plant was considered to be the best option, because it was the most cost effective, robust solution in a challenging environment. EWS then looked into a number of different DI solutions including an option for water recovery De – I which involved recovering the maximum volume of water, minimising new water costs and water wastage whilst maintaining the production process.
