Overview
The submersible recirculation pump is a special equipment improved on the basis of submersible mixer technology. The submersible recirculation pump has the characteristics of low head and large flow. Its function is to realize the activated sludge circulation through sludge return and promote the denitrification process. To maintain the concentration of activated sludge and microbial balance in the system. It can also be used in scenarios such as raw water transportation, cooling water circulation and irrigation.
Application

Municipal sewage treatment plants
Industrial wastewater treatment facilities
Recycling in wastewater treatment processes
Rural or small sewage treatment stations
Sludge concentration and dehydration systems
Ecological wetland or artificial wetland systems
Wastewater treatment processes such as activated sludge process, A²/O process, SBR process, etc.
Structural Features
Compact Design
Small size, light weight, easy to install and maintain
01
Corrosion-resistant Material
Stainless steel and other corrosion-resistant materials are usually used to adapt to the corrosive environment of sewage and sludge.
02
Non-clogging Impeller Design
Can effectively prevent clogging by impurities such as fibers and solid particles in the sludge.
03
Feature
High wear resistance and long service life
04
Strong Adjustability
The impeller of some sludge return pumps can be adjusted to meet different flow and head requirements
05
