The dewatering effect of sludge enhancer in plate and frame filter press is significant, which is manifested in the following aspects:
One. Dehydration effect
Sludge enhancer combined with plate and frame filter press can significantly reduce the moisture content of sludge. After the conditioning of the sludge, under the pressure of the plate and frame filter press, the moisture content of the sludge can be effectively reduced to 35%~55%, and the deep dehydration of the sludge is realized.
Two, improve the filtration efficiency
The use of sludge synergists can also greatly improve the filtration efficiency of the plate and frame filter press. Compared with the traditional sludge dehydrating agent, the sludge enhancer can reduce the press filtration period and increase the mud press efficiency by 100% to 500%, thus greatly shortening the dewatering time.
Third, the friendliness of equipment
Traditional water treatment agents such as polyacrylamide, polyaluminum chloride, etc., may cause corrosion to sludge dewatering equipment, or cause blockage to filter cloth. The sludge enhancer can effectively avoid these problems, it will not corrode the equipment, nor will it block the filter cloth, thereby extending the service life of the equipment and reducing maintenance costs.
Four, conducive to subsequent processing
The moisture content of the sludge after treatment with sludge improver is greatly reduced, which is conducive to the subsequent treatment of the sludge, such as incineration, brick making and composting. This not only improves the resource utilization rate of sludge, but also reduces the pollution of sludge to the environment.
Five, cost savings
The use of sludge synergists can also save costs for sewage sludge treatment enterprises. Since the sludge enhancer does not require the addition of auxiliary agents such as lime, the amount of agents used can be reduced, thus reducing the treatment cost. At the same time, due to the improvement of the filtration efficiency and the shortening of the filtration cycle, the operating time and energy consumption of the equipment can also be reduced, and the cost can be further reduced.
In summary, the dewatering effect of the sludge synergist in the plate and frame filter press is remarkable, which has the advantages of improving the dewatering efficiency, being friendly to the equipment, conducive to follow-up treatment and cost saving. Therefore, it has a wide range of application prospects in the field of sludge treatment.
