How much polyaluminum chloride should be added to the aerobic tank?
Thread Content
Recently, the system was subjected to water ingress, causing severe sludge disintegration! SV30 has dropped from 23 to 19, and this trend continues; therefore I want to add some polychloride to aid sedimentation in order to prevent excessive loss! So I’d like to ask everyone how they add it and how much to add? For the addition site, is it better to use a solid or a liquid?
Add 0.05–0.1 kilograms of PAC per ton of water; adding PAM at the same time yields even better results； If PAM is added, PAC can be halved. It is added by dissolving PAC at a concentration of 5–10% and then adding it. However, this is a temporary measure; the problem with the aerobic tank still needs to be resolved fundamentally.
