Small grid reactor is a new type of high-efficiency flocculation equipment developed and produced in recent years. Due to its good hydraulic performance and convenient installation and maintenance, it is increasingly widely used in water plants, reclaimed water reuse projects, advanced treatment sections of sewage treatment plants and other projects, with significant social and economic benefits.
The small grid reactor is equipped with vortex street device to better distribute water flow and enhance reaction effect. The small grid reactor can make the water flow generate high-frequency spectrum array vortex, and the alum produced is dense. The small grid reactor divides the reaction section into three stages. The first stage reaction is the most violent, which ensures the full contact between the agent and the particles in the water, creating favorable conditions for the formation of dense alum flowers. The secondary and tertiary reaction flow rates gradually decrease, during which the dense alum flowers gradually form, and then flow slowly through two transition sections. The dense alum flowers enter the sedimentation tank, laying a solid foundation for the subsequent sedimentation work.
The small grid reactor equipment is integrated, easy to install, simple to manage and maintain, and has strong adaptability to changes in raw water volume and water quality. It can adapt to high turbidity water, low turbidity water and slightly polluted water that are difficult to treat, and has stable flocculation effect. The small grid reactor equipment can rotate by itself under the effect of hydraulic conditions to prevent sludge and inhibit the growth of algae.
