Case Study, River Biorehabilitation
Guangfu River is typical tributary for Pearl River, but in recent years, caused by
untreated sewager and incomliance industrial wastewater discharge, water quality become
deteriorated with blakc moss and smelly odor. Goverment investigated pollution source and
order pollluter to rectification within limited time, after that start implement bio remediation
for Guangfu river.
1) Interception for domestic waste,
2) Base on core technology of microbial enzyme, dosing Aqua Clean + Sludge removal+
Ammonia Control + Odor Control
3) Install air diffuser to create aerobic for providing sufficient D.O for microbe growth and
4) Install floating wetland for microbe carrier, increase purification ability for
During bio remediation, Tangsons overcamed all difficulties and carried out strict pollution
monitoring on the river channel, initiate the timely emergency mechanism, implemeted
ecological restoration and management for black-odor river treatment in all direction after 60
days, finally turn black-odor river into benchmark river scenery line.
