Water Recycling in Paper Production
In order to minimize business costs and water demand MEPCO developed an on site water recycling process. This involved the installation of screens, drum filters, dissolved air flotation units and gravity filters. The company also installed an effluent treatment plant.
At a capital cost of US$5,700,000, funded entirely by MEPCO, plant water demand reduced from 20,000 liters to 5,000 liters per ton of product, adding to the total reduction of 6,000,000m3/year. The return on investment for all technologies installed only took approximately two years. The plant also recycles 2,500kg of paper each day.
