Obtained a utility model patent with patent number ZL 2017 2 1573288.7.

Basic Principles

The external ultrafiltration integrated equipment includes membrane elements, cleaning system, control system, and dosing system. Efficient integration and high degree of automation. It is a membrane separation process that uses screening as the separation principle and pressure as the driving force. The filtration accuracy is in the range of 0.005-0.01 μ m, which can effectively remove particles, colloids, bacteria, and high molecular organic matter from sewage.

Technical advantage

(1) The effluent quality is of high quality and stable, with no bacteria or suspended solids in the effluent;

(2) Low sludge load (F/M) and low residual sludge production;

(3) Efficient integration of reactors, small footprint, and no limitations on installation scenarios;

(4) The main pollutants COD and BOD are effectively degraded without secondary pollution;

(5) Convenient operation management and easy implementation of automatic control;

(6) The application of external tubular ultrafiltration membranes avoids the disadvantages of easy contamination and blockage of internal membrane biochemical reaction membranes.

Applicable fields

Suitable for solid-liquid separation of wastewater, intercepting impurities with molecular weights ranging from 10 ² to 10 ⁵ daltons.
