What are steps adopted by these three plants for treatment of sewage?
With pre-treatment and preliminary treatment such as pollutant interception and sediment completed, sewage treated by the secondary high-effective activated sludge process containing steps like bio-aeration and secondary clarification to decontaminated water is discharged into the Tamsui River every day wherein 10,000 tons are recycled for repeated employment via sand filtration. Dehydrated from sludge via steps of concentration and anaerobic digestion, sludge cakes are instructed to the operating vendor authorizing another professional vendor for follow-up treatment.
With pre-treatment and preliminary treatment such as pollutant interception and sediment completed, sewage treated by the secondary high-effective activated sludge process containing steps like bio-aeration and secondary clarification to decontaminated water is discharged into the Keelung River.
