Municipal sludge is the solid precipitated substance produced in the water treatment process of sewage treatment plants or tap water sewage plants, and municipal sludge is the largest type of sludge. The main characteristic of municipal sludge is high moisture content (general moisture content of more than 99%), sewage including interstitive water (free water), capillary water, adsorption water, internal water, the first two can be removed by mechanical force with the help of dewatering equipment, and the last two are generally difficult to remove using sludge dewatering equipment. The sludge separated from industrial wastewater has complex composition, high organic content and contains a large number of microorganisms, machinery quality and rich nitrogen, potassium and other nutrients, as well as harmful substances such as bacteria, inorganic particles, heavy metals, pathogenic microorganisms, which are not well treated and easy to cause secondary pollution to the environment.
Municipal sludge contains a lot of water, if not conditioning treatment, direct dehydration treatment, will lead to excessive dewatering equipment load, increased energy consumption, but also may affect the sludge dewatering effect. Therefore, before the use of sludge dewatering equipment, it is necessary to use conditioners to reduce the moisture content of the sludge and improve the efficiency of dehydration.
Sludge conditioner is a kind of high performance cationic polymer, its specific chemical properties make it have a strong electrical neutralization, specially used in sludge dehydration and coagulation treatment. Suitable for domestic sewage treatment plant, industrial sewage treatment plant, kitchen waste treatment plant, paper mill, printing and dyeing plant, oily sludge, high organic sludge, low dewatering rate of sludge, etc.
Product performance:
1. Unique dewatering ability, excellent performance in the dewatering treatment of various industrial sludge.
2. Due to its special parent structure, it is suitable for plate and frame dehydration treatment, and the moisture content of the treated sludge can reach less than 50% [the dehydration rate of ordinary polyacrylamide is about 75%], which can reduce the factory sludge by 30%-45%.
3. When applied to plate and frame demudding water treatment, it can replace the use of calcium salt and iron salt, and can also be used together to achieve better sludge dehydration and sludge reduction effect, and does not block the filter cloth and does not affect the normal operation of the equipment.
4. For oily and high organic sludge, the treatment effect is good, and the mud pressing speed is fast.
