Small screw conveyor systems for dosing dry powder of flocculant in sewage treatment

Small screw conveyor systems can be used for the experimental proportioning of flocculant for sewage treatment and the configuration of aqueous solution of flocculant for sewage treatment.

Sewage flocculants can be used in industrial water treatment systems in urban water supply treatment, sewage treatment, paper mills, garment factories, food factories and other industries, which can effectively remove microorganisms and pathogenic bacteria in water, and can remove emulsified oil and chromaticity in sewage. , heavy metal ions and other pollutants.

Granular polymer flocculants cannot be directly added to sewage. It must be dissolved in water before use, and its aqueous solution is used to treat sewage.

1 ton of sewage usually needs to add about 1-10g of flocculant, which should be adjusted according to the specific situation of sewage. Before use, it is necessary to carry out experimental proportioning to obtain the type and dosage to be added. Small screw conveyor systems have accurate and stable feeding and can be directly used in the experimental proportioning of flocculants in sewage treatment.

In specific use, Small screw conveyor systems are installed under the weighing screw conveyor or silo, and a certain weight or proportion of the flocculant is forcibly fed into the ejector or mixing equipment, and the flocculant is quickly dispersed and fully mixed with water. Form sewage treatment flocculant water solvent.

Then, the prepared flocculant aqueous solution is sent into the sewage tank by Small screw conveyor systems, and the chemical and the suspended solids in the sewage are in contact with each other during the flow of the water body, and the adsorption bridging reaction occurs, and the impurities are separated from the water. After that, the solid-liquid separation and other steps are carried out on the sewage to complete the sewage treatment work.
