Common problems and solutions in the use of polyaluminum chloride (PAC)

As a widely used sewage treatment agent, polyaluminum chloride may encounter some common problems during its use. Here are some common problems and how to solve them: 1.Large particles of alum flowers rise on the surface of sedimentation tank Reason: the dosage of polyaluminum chloride is too large Methods: Appropriately reduce the dosage of chemicals, or strengthen the drainage of mud operations 2.In the clear water area, there is a fine flocculent rising, and the effluent is cloudy Reason: too much water and insufficient dosage of polyaluminum chloride Methods: Reduce the amount of water and increase the dosage of polyaluminum chloride 3.When the height or concentration of the sludge layer increases too quickly, the turbidity of the effluent rises Reason: the amount of mud discharge is small, and the sludge accumulates in the system Methods: To shorten the sludge discharge period and extend the sludge discharge time in order to effectively control the height and concentration of the sludge layer 4.There are more bubbles in the clean water area Reason: the amount of lime water is too large, the sludge in the tank long-term precipitation fermentation, produce gas. Solution: Reduce the amount of lime water added, shut down the equipment and carry out your operation to release the air in the pool 5.Turning flowers Causes: the water temperature is too high, the water flow is too large, the dosing is interrupted, the mud is not discharged in time, and the sludge layer is too high Method: Reduce the water temperature to the normal value, reduce the amount of water, add medicine in time, drain mud in time, and control the height of the disobedient layer The main products of flocculant manufacturer Xinhuan Water Treatment are: White polyaluminium chloride (food grade), drinking grade polyaluminium chloride, industrial grade polyaluminium chloride, anionic polyacrylamide, cationic polyacrylamide, nonionic polyacrylamide, Activated carbon,petroleum recycling polyacrylamide, oil recovery polyacrylamide, polyacrylamide, polymer flocculant polymer flocculation coagulant, polymeric ferrous sulphate, polymerized iron and aluminium chloride, and other water treatment chemicals.
