Special Dewatering Filter 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 without sticking to the filter cloth. It has obvious gel-breaking and cell wall-breaking effects. After entering the mud system, it quickly integrates and reacts with the mud, fully utilizing the charge collision destabilization and bridging adsorption coagulation principles of inorganic coagulants to break the cell walls and coagulate the hydrophilic cell membranes of colloidal particles in the mud. At the same time, it works with the large molecular chain structure of polymer flocculants for rapid coagulation and filtration assistance. 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 landfill! It is a highly efficient, harmless, and low-moisture-content composite mud dewatering agent specifically developed for various municipal sewage muds.

Usage Method

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