Polyacrylamide In The Inorganic Sludge
May 26, 2017

Polyacrylamide has been widely used in various industries because of its many properties, and the properties of polyacrylamide are after use, Polyacrylamide we need to know how to buy polyacrylamide, the following is a personal summary of the purchase of high quality polyacrylamide six steps 1, sludge is the city sewage treatment of the inevitable product, first of all we should understand the source of sludge, nature, composition and solid content. According to the main components of sludge, sludge can be divided into organic sludge and inorganic sludge. In general, cationic polyacrylamide is used to treat organic sludge, Polyacrylamide anionic polyacrylamide is used for inorganic sludge, it is not suitable to use cationic polyacrylamide when it is very strong, and it is not suitable to use anionic polyacrylamide when the acidity is strong, and the dosage of polyacrylamide is usually higher when solid content is high.


2, the size of the Floc: Polyacrylamide The Floc is too small will affect the speed of drainage, flocculation group too General Assembly to bind more water and reduce the mud biscuit degree. The size of the Floc can be adjusted by selecting the molecular weight of polyacrylamide.


3, the Ionic degree of polyacrylamide: for dewatering sludge, the use of different ionic degrees of flocculant by first doing small test screening, Polyacrylamide the best suitable polyacrylamide, so that can obtain the best flocculant effect, but also to add the minimum dose, save costs.


4, the strength of the Floc: Floc in the shear action should remain stable without breaking. Increasing the molecular weight of polyacrylamide or selecting suitable molecular structure can help to improve the stability of the floc.


5, polyacrylamide and sludge mixing: polyacrylamide in the dehydration equipment at a certain location must be fully responsive to the sludge, the role. Polyacrylamide To this end, the viscosity of polyacrylamide solution must be appropriate, under the existing equipment conditions can be fully mixed with the sludge, the mixture of the two is the key factor of success. The viscosity of polyacrylamide solution is related to its molecular weight and preparation concentration.


6, the dissolution of polyacrylamide: good dissolution to give full play to flocculation. It is sometimes necessary to accelerate the dissolution rate, when the concentration of polyacrylamide solution can be considered.
