In designing a wastewater reuse system, it is indispensable to develop a compact, easy-maintenance and cost-effective treatment scheme that is capable of removal of phosphorus and nitrogen as well as organic matter effectively. To meet these requirements, a pre-coagulation and bio-filtration process was developed in this study. A precoagulation process has some merits:
1. suspended and some soluble organics can be removed effectively,
(a) nitrification in the following biological treatment is enhanced,
(b) SS loading into the following filter is reduced,
2. phosphorus can be removed effectively.
Bio-filtration has advantages that filtration and biological activities were combined in a single reactor with aid of media. Maintenance is facilitated because there is no need of sludge recycling and operation of a final clarifier.
nitrogen and phosphorus removal ratios of their processes are about 77% and 72~83%, respectively. A target phosphorus concentration was around 1mg P/L.
These results proved that this process is applicable to advanced treatment of sewage with easy maintenance.
