Experimental Study on Conditioning Residual Activated Sludge by Dual Conditioners

To select conditioner for the process of thickening residual activated sludge from Chaoyangzhou Wastewater Treatment Plant in Nanchang by cavitations air floatation (CAF), some conditioning experiments were done by dual conditioners. Results showed that dual conditioners such as PAC+ FO4440SH, PAC+ FO4190SH, PAC+ FA920SH and PAC+ AN926SHU were given a more comprehensive consideration effect of sludge conditioning, comparing with inorganic conditioners alone. Since PAC+ FO4440SH showed the best effect of sludge conditioning, it was selected for sludge conditioning for the WTTP.
