·Continuous concentration of the sludge treatment.Economical and practical, performance outstanding.

·Concentrated sludge solid content up to 6-12% DS.

·Sludge thickening tanks can be alternated; it is the ideal mechanism to solve sludge problems.


·The GLN-screw extrusion drum sludge thickening machine is a mechanical, low-rotating speed, body hermetically sealed, continuous operation. These characteristics can be used to distinguish traditional method of sludge treatment (traditional coagulation tank operated by large-scaled concentrated scraper harrow). The sludge thickener consists of Wedge-shaped cylindrical stainless steel filter and screen-screw-shaft with variable pitch, variable axial-radial axis and reasonable changed gradient. The filter is made of high quality stainless steel, which was treated by pickling passivation already to increase corrosion-resistance.

·The sludge which's solid content approximately at 0.5%DS passes through fluidic feeding device, mixes with flocculant liquid , then be transported into mixing reactor. When the concentration of homogeneous is stable, then the sludge flows into thickener. The sludge is slowly upgraded by screw axis from low-end to the high-end and be concentrated during this conveyance. All processes take place in the hermetically sealed device. The solid content of the sludge can reach 6%--12%DS. The filtrate percolates through the filter. In order to discharge thick mud successfully, the installation angle of thickener is 30o.

·Sludge thickening machine is equipped with pre-set automatic cleaning device, Mechanical operation and the effect of enrichment will not be affected by the washing process. Concentrated sludge will be dumped into the thick mud collection box for the follow-up process. This system is equipped with a fully automatic powder / liquid flocculant delivery device, the preparation of the flocculant can be continuously generated by single fully automatic equipment.

·GLN-sludge thickener occupies less area, requires less energy but will be given the effect of high sludge concentration. GLN-Sludge Thickener applied to a variety of enrichment requirements.
