The reverse osmosis plant that C&S Water Treatment Ltd recommended now enables site to manufacture ice more efficiently with regards to quality and cost. Their existing set up involves using 30m3/hr of treated water through reverse osmosis to be used for production whilst the remaining 15m3/hr goes to drain. Our proposals involved taking this 15m3/hr reject water and passing it through another stage of reverse osmosis resulting in a reduction of effluent by 50% and also utilising a further 7.5m3/hr of water in production. The CAPEX costs are around £100K with a payback of around 12 months. The profit thereafter is around £75k per annum after extra operational costs.
