What type of flocculant is suitable for the centrifuge used in sludge dewatering? We know that in sludge dewatering, polyacrylamide is mostly used. Generally, the combination of polyacrylamide and polyaluminum chloride can achieve the ideal effect in sludge dewatering.

In sludge dewatering, most of the filter presses need to be combined with water purification agents. Different types of filter presses need to be combined with different agents. Filter press generally includes crawler filter press, roller filter press and centrifugal filter press. Centrifugal filter press is a new generation of sludge dewatering equipment with unique advantages. When the centrifuge is running, the sludge and water purification agent can be mixed more evenly, and the desliming amount is higher. However, because of the rotation of the centrifuge, it is easy to disperse the sludge, so the water purification agent should be selected according to the characteristics of the centrifuge.

What type of flocculant is suitable for the centrifuge used in sludge dewatering? It needs to be considered comprehensively according to the characteristics of sludge and the type of filter press. First of all, polyacrylamide is mostly used for sludge dewatering at present. Combined with polyaluminum chloride, large dense and solid sludge can be formed, which will not be broken by centrifuge and will affect sludge dewatering effect. But we need to choose some high molecular weight polyacrylamide, only high molecular weight polyacrylamide can make the sludge more solid. However, polyacrylamide and polyaluminum chloride should be selected according to the properties of sludge.

What type of flocculant is suitable for the centrifuge used in sludge dewatering? Generally, polyacrylamide and polyaluminium chloride are used to match the sludge treatment characteristics, but high content polyacrylamide is needed.
