Most of the paper sludge is composed of cellulose organic matter, nitrogen, phosphorus, potassium and other plant nutrients, and contains a certain amount of trace heavy metals and pathogenic bacteria. According to the characteristics of the sludge containing plant nutrients, the sludge can be processed into organic fertilizer. So how can we effectively remove the water in the sludge?

The paper industry generally adopts the method of filter press to remove the water in the sludge. Due to the different papermaking process, the amount of chemicals is also different. After sludge concentration, before entering the mechanical dehydration, it is necessary to add chemical agents - inorganic flocculant polyaluminum chloride, ferrous sulfate and organic flocculant polyacrylamide for treatment.

However, the use of sludge synergist sludge dewatering effect will be better, for the organic flocculating polymer sludge adjuster. Due to the large flocculant formed by the sludge booster, the press filtration process produces a lot of water, and the water content of the extruded mud cake is low.

The moisture content of mud cake can reach about 50-60%, which is convenient for post-processing. After the mud cake is obtained, it is further processed into organic fertilizer to realize the transformation of waste into treasure.

Sludge synergist features:

1, the use of sludge synergist is economical, the amount is very small, the effect is good;

2, can significantly improve the production efficiency or increase the solid content of mud cake;

3, sludge synergist soluble in water;

4, in the production process of solid-liquid separation, can improve the capture rate of solids;

5, effective work in a wide pH range.
