Plate and frame filter presses are widely used in sludge dewatering treatment, but the dewatering rate is often affected by multiple factors. Improving the dewatering rate is the key to enhancing treatment efficiency and reducing costs. The emergence of sludge enhancers has provided an effective solution to this problem.

What factors affect the dehydration rate

Youdaoplaceholder0 Sludge characteristics ‌ : The organic matter content, particle size and distribution of sludge, etc., will affect the degree of combination between water and sludge particles. Sludge with high organic matter content and fine particles has strong water-holding capacity and is difficult to dewater.

The use of ‌ chemicals ‌ : Traditional dewatering chemicals such as polyaluminium chloride and polyacrylamide can improve the dewatering performance of sludge, but their effect on complex sludge is limited, and they may leave chemical residues that affect subsequent treatment.

Youdaoplaceholder0 Operating conditions ‌ : Operating parameters such as filtration pressure, filtration time and feeding speed have a significant impact on the dewatering effect. Insufficient pressure, too short a time or too fast feeding can all lead to incomplete dehydration.

How can sludge enhancers improve the dewatering rate

Youdaoplaceholder0 Breaking cell structure ‌ : The microbial cells in sludge contain a large amount of bound water. The sludge enhancer can penetrate the cell wall, destroy the cell structure, release bound water, and reduce the water-holding capacity of the sludge.

Youdaoplaceholder0 Enhance floc performance ‌ : The sludge enhancer can optimize the structure of sludge flocs, form larger and denser flocs, increase the strength and stability of flocs, reduce floc breakage during the filtration process, prevent filter cloth clogging, and accelerate water discharge.

Youdaoplaceholder0 Regulating sludge properties ‌ : Some sludge enhancers can adjust the pH value and charge properties of sludge, improve the dewatering environment of sludge, enhance the coagulation effect between sludge particles, and further improve the dewatering effect.

Selection and usage suggestions

Youdaoplaceholder0 Selection ‌ : According to the nature of the sludge and the treatment requirements, choose the appropriate sludge enhancer. The dehydration effect, cost and environmental friendliness of different products can be compared through small-scale tests, and the best product can be selected.

Youdaoplaceholder0 usage ‌ : Strictly determine the dosage and addition method of the reagent in accordance with the product manual. Generally, the sludge enhancer is thoroughly mixed with the sludge first, and then it enters the plate and frame filter press for dewatering treatment. At the same time, pay attention to controlling the operation parameters to ensure the stability of the dehydration effect.
