Potable water is sold to the client through a multi-year agreement (minimum 10 years). DDFS provides and owns all the assets through a turnkey installation. The industrial salts are sold to fertilizer companies which generates additional income. DDFS managed to reduce the cost of producing water significantly through addressing the energy and waste problems. Our Zero Liquid Discharge Reverse Osmosis system with Energy Recovery hydro system is modular, stand-alone, energy efficient and able to handle both inland borehole water and sea water.
This current report is based on the improvements DDFS can bring to the South African Reverse Osmosis industry. The comparison for Reverse Osmosis systemâs simulation was based on Total Dissolved Solids 5,000 ppm levels or 559 millisiemens per meter (mS/m) with very high silica levels in the feed stream to produce 1,000 m3 / day permeate.
