Sludge dehydrating agent, also known as sludge conditioner, is a high-performance cationic polymer, its specific chemical properties make it have a strong electrical neutralization, can change the sludge surface structure, reduce the sludge solid surface load, reduce the specific surface area of the sludge surface, dedicated to sludge dehydration and coagulation treatment.
As a drying agent in sludge dewatering process, compared with traditional PAM flocculant, it can significantly reduce the water content of sludge. The main components are inorganic compounds, sludge surface structure modifier, degreaser, wall breaking agent, sludge surface treatment agent, sludge stripping agent, etc. All or part of the replacement of the inorganic flocculants and conditioning agents such as polyferric chloride, polyaluminum chloride and lime used in the sludge deep dewatering process, combined with the plate and frame mud press, can reduce the moisture content of the sludge from more than 90% to 40%-60%, and fully realize the sludge reduction.
The use of sludge dehydrating agent (sludge conditioner) has the following advantages:
1. It can maintain the properties of sludge and organic matter content without increasing the amount of sludge, and does not change the pH value and salt content of filtrate.
2. the unique dewatering ability, in a variety of industrial sludge dehydration treatment convenient performance.
3. the moisture content of sludge can meet the requirements of reuse, and the sludge can turn waste into treasure.
4. does not contain any inorganic salt, the mud cake after deep drying does not harden.
5. after adding sludge dehydrating agent, the filter material is almost non-stick filtration equipment, reducing the cost of equipment cleaning.
6. the dehydration speed is fast, the clarity of the filter water can reduce the difficulty of subsequent wastewater treatment.
Sludge dewatering agent (sludge conditioner) treatment effect is good, cost-effective, can be widely used in domestic sewage, printing and dyeing plants, paper mills and other industries sludge dewatering treatment, to achieve efficient concentration and dehydration.
