Description
PRODUCT PROFILE:1. Commonly used equipment for sludge dewatering includes plate and frame filter presses, belt filter presses, screw-type filter presses, etc. Cationic polyacrylamide is generally used for sludge dewatering. The specific model can be tested and comparatively analyzed according to different sludge properties to determine the model of water treatment agent polyacrylamide. 2. The dosage of polyacrylamide The conditioning of sludge has a great relationship with the dosage of chemicals. Insufficient dosage of chemicals can not effectively remove impurities in sewage. Sludge treatment will cause mud runoff and thin mud cake; excessive dosage will not only cause waste and increase costs, but also increase the nitrogen content in sewage. The filterability of the mud treatment is reduced, and the better treatment effect is still not achieved. Therefore, it is necessary to do a small test to determine the dosage of the medicine. In order to achieve better results.
3. It is related to filter cloth selection or filter cloth breathability If it is a new filter cloth, the filtering effect is no problem. If the filter cloth is contaminated, it needs to be cleaned in time, otherwise it will also affect the dehydration effect.Application industries:1. It is mainly used for the sludge dewatering and decrease the rate of water content of sludge.
2. It can be used to treat industrial wastewater and life sewage water.
3. It can be used for paper making to improve dry and wet strength of paper and to improve dry and wet strength of paper and to increase the reservation of tiny fibers and fillings.Specification | Anionic polyacrylamide |
