Sludge is the product of sewage treatment process, mainly composed of low organic matter such as amino acids, humic acid, bacteria and their metabolites, in addition, it also contains inorganic substances and mercury, cadmium, lead and other heavy metals. Today, Qingdao Shijun introduced a new sludge dewatering agent that can reduce the moisture content of sludge to 40%-60%. Sludge water content reduction agent (sludge conditioner) is a chemical agent that can change the surface structure of the sludge, reduce the surface load of the sludge solid, reduce the specific surface area of the sludge surface, and destroy the bacterial structure.

The main components of sludge conditioner are inorganic compounds, sludge surface structure modifier, degreaser, wall breaking agent, sludge surface treatment agent, sludge stripping agent, etc. Sludge water content reduction agent (sludge conditioner) has the advantages of small dosage, low cost, breaking the bottleneck of sludge dehydration, achieving efficient concentration and dehydration, good treatment effect and high cost performance. Sludge water content reduction agent (sludge conditioner) is widely used in life, printing and dyeing, paper making, electroplating, chemical industry, leather and other industries of sludge dewatering treatment.

The sludge moisture reduction agent (sludge conditioner) combined with the plate and frame mud press can reduce the sludge moisture content from more than 90% to 40%-60%, and fully realize the sludge reduction. After the sludge conditioning agent is used, the pressure of about 1.0MP is injected into the filter chamber of the filter press to efficiently filter out the free water in the sludge. When the chemical conditioning achieves better results, the high pressure feeding and high pressure pressing can shorten the time of the entire press section and improve the production efficiency.
