Flocculation grid reactor

Grid flocculation reactor (also known as grid flocculation tank) is widely used in water purification of waterworks, upgrading and transformation of urban sewage treatment plants, and industrial wastewater treatment projects such as printing and dyeing, chemical, papermaking, and pharmaceuticals. Suitable for surface water purification, reclaimed water reuse projects, and various raw water quality conditions such as high turbidity, low turbidity, and micro pollution. It can be used for efficient flocculation units in newly built water plants, as well as for upgrading and renovating existing partition flocculation tanks and perforated cyclone flocculation tanks to improve flocculation efficiency, shorten reaction time, and reduce drug consumption.

Product Introduction

A grid flocculation reactor is a water treatment device that promotes the collision and adhesion of suspended particles in water to form flocs by arranging multiple layers of grids or grating elements in the flow channel. It utilizes the inertial effect and vortex shear generated as water passes through the grids. The core structure adopts a multi-compartment vertical flow recirculation design, consisting of a stainless steel external frame assembled with multiple thickened PP (or ABS, stainless steel) grid bars. The number of grid layers gradually decreases from the inlet end to the outlet end. The partitions between grid layers are arranged in a staggered up-down pattern, causing the water flow to contract and expand successively as it passes through the grids, thereby generating micro-vortices.

Technical Advantage
High flocculation efficiency and short reaction time
The micro vortices generated by the grid significantly increase the frequency of particle collisions, shortening the residence time by about 40% to 50% compared to traditional baffle flocculation tanks. The flocculation process can generally be completed within 10-15 minutes. After the renovation of a water plant in the south, the turbidity removal rate of the filtered water increased by 10.67%.
Save medication and reduce operating costs
By optimizing energy allocation and enhancing particle collision, the dosage of coagulant can be reduced. Engineering cases show that the dosage of medication can be reduced by 24.3%.
Small head loss
The head loss of the grid (bar) reaction tank is generally 0.1-0.15m, and the operating energy consumption is low.
Strong resistance to impact load
Strong adaptability to changes in raw water quantity and quality, able to maintain stable flocculation effect. However, it should be noted that large fluctuations in water volume may affect flocculation efficiency, and it is recommended to use it in situations where the water volume is relatively stable.
Modular structure and easy installation and maintenance
The grid flocculation reactor adopts an integrated module design, with a peripheral frame made of 304 stainless steel and grid bars assembled from thickened PP or ABS materials for easy processing, transportation, assembly, and replacement. The structure is simple, reliable, and easy to maintain.
