The "AERO" series of grease traps are aerated grease traps that are designed for cleaning industrial fat-containing wastewater before discharge into the general sewer network, in order to prevent emergency shutdowns of the internal sewerage of buildings as a result of the formation of fat deposits on the internal walls of the pipeline.
The "AERO" series of grease traps are aerated grease traps that are designed for cleaning industrial fat-containing wastewater before discharge into the general sewer network, in order to prevent emergency shutdowns of the internal sewerage of buildings as a result of the formation of fat deposits on the internal walls of the pipeline. Specifications: Length: 800, Width: 600, Height: 450, Capacity, m3 / h: 1.75, Peak discharge, l: 150, Pipe diameter: 50 or 110, Inlet height (center): 380, Outlet height (center): 375, Fat efficiency: up to 98%, Organic waste efficiency: up to 80%, Production: Russia, Non-standard design: possible
An additional positive effect of the use of aerated grease traps is to increase the overall efficiency of subsequent treatment facilities (biological treatment plants, etc.)
The principle of operation and technological process of wastewater treatment
The principle of operation of aerated grease traps of all models of OV is developed on the basis of the experience of large sewage treatment plants with constant small-bubble aeration and classic settling tanks of various types. The above-mentioned technologies are combined in the "AERO" series of grease traps.
During the development, the engineers proceeded from the existing experience in the production of water treatment equipment for industrial wastewater characterized by uneven inflow.
The treatment of incoming wastewater can be divided into two stages:
Deceleration of the flow and settling, as a result of which the gravitational separation of suspended particles and emulsified fat products occurs. At this stage, the suspended substances (food waste) coming from the general effluent are deposited and the non-emulsified fat products are separated (surfaced) to the water surface.
Aeration is the process of saturation of wastewater with oxygen, in order to intensify the formation of colonies of aerobic bacteria that actively break down organic pollutants and block all rotting processes (the action of anaerobic bacteria) that cause the appearance of sharp unpleasant odors.
In addition, as a result of fine bubble aeration, the capture of fat products dissolved in water (emulsified) occurs and their intensive removal to the surface, which entails a significant increase in overall efficiency
