Most enterprises deeply engaged in the wastewater treatment and sludge disposal industries are plagued by three persistent problems: filter cloth sticking and difficult discharging, excessive moisture content in sludge cakes, and .....

In the actual operation and maintenance of plate and frame filter for sludge treatment, most plants generally encounter problems such as long sludge inlet time, insufficient cake thickness, and low sludge output. The core cause li.....

Municipal and industrial sludges contain a large amount of colloidal particles, intracellular water of microorganisms and bound water. After conventional treatment with chemicals, the sludge has low dehydration efficiency and the .....

In municipal wastewater treatment plants, sludge dewatering has always been a troublesome "chronic problem". In traditional processes, in order to reduce the moisture content, a large amount of lime and iron salts are of.....

The sludge specific resistance is a key technical indicator for measuring the difficulty of dewatering. The higher the specific resistance value, the more difficult it is for water to pass through the sludge layer, and the lower t.....

At present, the majority of domestic plate-and-frame sludge deep dehydration systems still employ inorganic conditioning systems consisting of PAC, polymeric iron, and lime. This process is mature and has a straightforward cost st.....
