Plate and frame filter press is widely used in the field of sludge dehydration, so what sludge conditioner or sludge filter aid should be used to dry the sludge? Works Chemical shares the following experience here, in many cases, the use of improper agents can lead to sticky tape over the filter cloth or side leakage problems. Printing and dyeing sludge, after physical and chemical treatment, influent COD is 800, after treatment is 200-300, it is difficult to debug.
Works Chemical- Sludge conditioner, sludge dewatering synergist manufacturer
In the treatment of various types of sewage, the sewage will contain solid substances. For example. In the sewage of the municipal sewage plant, the solid substances contained are mainly colloidal particulate matter, which has a strong affinity with water. Dehydration can be very difficult if proper treatment measures are not taken. So what sludge conditioner (sludge dehydrating agent) or sludge filter aid should be used to dry the sludge?
The new sludge conditioner is a characteristic polymer, as a drying agent in the sludge dewatering process, compared with the traditional PAM flocculant, it can significantly reduce the water content of the sludge, and completely or partially replace the inorganic flocculants and adjuster such as polyferric chloride, polyaluminum chloride and lime used in the sludge deep dewatering process, so as to achieve real sludge reduction. At the same time, the properties of sludge and organic matter content are maintained, and the pH value and salt content of filtrate are not changed. After the use of sludge conditioner combined with the plate and frame filter press, the weight of the pressed sludge is obviously reduced, and the moisture content of the mud cake can be 40%-60%; At the same time, the mud press efficiency is increased by 100%-500%, which greatly shorens the mud press cycle, and also shorens the frequency of the filter cloth of the plate and frame filter press, saving the operating costs.
