Treating piggery wastewater

Constructed wetlands (CWs) have been used to treat various types of wastewaters such as urban runoff, acid mine drainage, municipal, industrial, and livestock wastewaters. This study was conducted to evaluate the effectiveness of two constructed wetlands (surface and horizontal subsurface flows) for piggery wastewater treatment after biogas process. The wetland plant Phragmites australis Cav. was used in two CWs. The flow rate of the CWs was 100 liters/day with the hydraulic retention time (HRT) of 3 days.

An investigation into the treatment efficiency of real piggery wastewater of a benchscale aerobic membrane bioreactor was performed. The experiments were aimed to evaluate the effects of hydraulic retention time and activated sludge concentration. The piggery wastewater having high chemical oxygen demand, ammonium and total phosphorus concentrations (about 4200 mg/l, 320 mg/L and 48 mg/L, respectively) was employed.
