• Preliminary process: First, foreign materials (such as wood pieces) from the waste water is removed using a golden sieve. Second, the filtered water is put into a mixing pond to adjust the alkaline content (fit for bacteria operation and pulp precipitation). Lastly, the temperature is adjusted and Urea Phosphate is added (a special compound which increases the efficiency of bacteria to digest contaminated water).
• The filtered water from the first process is delivered to an air accumulation pond wherein the oxygen content is increased. It will then digest all the contaminated substances and exhNLst it. Lastly, dregs are separated through the sediment tanks, and thus produce clean water (with the right BOD and COD level compatible with regulated standard from the Factory BureNL) as a finished result.
