Special Dewatering Filtration Aid for Plate and Frame Filter Press

--Special for Municipal Sewage

Product Introduction

The product is compounded from various inorganic salts, polymer flocculants and catalysts.

Product Features

The product can be added alone without the need for other flocculants to achieve ideal dewatering results and does not stick to the filter cloth. The product has obvious gel-breaking and cell wall-breaking effects. After entering the slurry system, it quickly integrates and reacts with the slurry, fully utilizing the coagulation and cell wall-breaking principles of inorganic coagulants through charge collision destabilization and bridging adsorption to break the cell walls and coagulate the hydrophilic cell membranes of colloidal particles in the slurry. At the same time, it works with the large molecular chain structure of polymer flocculants to quickly aid coagulation and filtration. The product contains various trace elements required by plants, such as iron, magnesium, calcium, etc., enabling the dewatered sludge to be reused as fertilizer, solving the secondary pollution problems of sludge incineration and landfilling! It is a highly efficient, harmless, and low moisture content composite slurry dewatering agent specifically developed for various municipal sewage slurries.

Usage Method

The solid product can be directly added to the slurry. When adding, it should be evenly and slowly introduced into a stirred slurry mixer. After stirring for about 20 minutes, it can be fed into the filter press. It can also be diluted for use at a ratio of 5-10‰. Dosage (reference amount): when the slurry concentration is 3000-6000 mg/L, 0.1-1 kg (solid) per ton (slurry). The specific dosage should be determined through on-site small-scale testing.
