Micro-vortex Clarifier

The micro-vortex clarifier is a high-speed integrated reaction sedimentation/concentration tank. Through micro-vortex coagulation and three-dimensional contact flocculation, it fully utilizes the coagulation space, coagulation energy and floc activity, greatly improving the coagulation reaction efficiency. This process can significantly improve the effluent quality, shorten the reaction time, reduce the consumption of coagulants, and is simple to construct, stable in operation, and easy to maintain. The micro-vortex high-density clarifier is mainly composed of a fast vortex reaction tank, a slow vortex reaction tank, a pre-sedimentation-concentration tank, an inclined tube separation zone, etc., and adopts a unique integrated reaction zone design. Features

1. An external sludge circulation system is set up to lift the sludge from the sludge concentration area to the reaction tank inlet pipe and mix it with the raw water;

2. Coagulation and flocculation are carried out in two vortex reaction zones. The efficient micro-vortex state in the reaction zone greatly improves the coagulation and flocculation effect;

3. Unique and efficient composite organic flocculants are used;

4. The high-efficiency inclined tube sedimentation layout is adopted. The alum flowers can be kept intact from the low-speed reaction zone to the inclined tube sedimentation zone, and the alum flowers produced are uniform in quality and high in density;

5. The high-efficiency inclined tube sedimentation zone with advanced technology is adopted. The rising speed of the sedimentation zone can reach 20~40m/h, and the dense alum flowers are well precipitated here;

6. It can effectively complete the sludge concentration, and the effluent water quality is stable and resistant to shock loads. Advantages

1. Sludge circulation improves the flocculation ability of the incoming sludge, making the flocs more uniform and dense;

2. The unique inclined tube arrangement improves the sedimentation effect, with a high sedimentation rate of up to 20m/h-40m/h. The high sedimentation efficiency makes the structure compact, reduces the civil engineering cost and saves installation land.

3. The effluent water quality is good, and the unique vortex structure and inclined tube separation produce high-quality effluent water; the inlet water is 2000mg/l, and the effluent water is about 10mg/l;

4. It is resistant to shock loads, is not affected by changes in flow or pollution load, and can withstand a wide range of flow changes;

5. The operating cost is low, compared with the existing process, it saves 10% to 30% of the reagents; at the same time, the water temperature can be reduced by 5~10℃;

6. The discharged sludge concentration is high: the integrated sludge concentration avoids the subsequent concentration process, and the generated sludge can be discharged directly. Compared with the static sedimentation tank, the water loss is very low.
