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:

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

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

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

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

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
