Tube settlers, also called lamella clarifiers, can produce by polypropylene(PP) , polyvinyll chloride(PVC), ethylene-propylene copolymer and FRP. Assembly in two from of oblique tube and straight tube.
Application
Tube settlers is mainly used for a variety of precipitation and desanding. It has a wide arange of applications, such as high processing effect, small footprint and son on. It is suitable for the new construction and transformation of the existing old pool, and can achieve good economic benefits.It is suitable for the transformation of existing old water tanks.
Straight tube is mainly used for bio-filter high- load bio filter, tower bio filter, submerged biological filter(also known as contact oxidation tank) and biological turntable microbial carrier, industrial organic wastewater adn urban sewage biochemical treatment.
Inclined tube features
1. Long wet weeks, small hydraulic radius.
2. The laminar flow is good and the sedimentation is not disturbed by flocculation.
3. When the pipe length is 1 meter, the payload is designed according to 3-5 tons/m2. V0 control in the 2.5-3.2 mm/2, the output water quality is good.
4. Use Inclined tube settler in the water intake, tube length of 2.0-3.0 meters, the 50-100kg/m3 sand content of high turbidity in the safe operation of treatment.
5. The process of capacity of inclined lamella clarifiers is 3-5 times of advection-type sedimentation and 2-3 times to accelerate the clarification pool and pulse clarification tank.
Straight tube features
1. The treatment efficiency is higher than the activated sludge method, the general hydraulic load : 100-200m3/m2 per day,
the orgainc load: 2000-5000 g/m3, so it reduced the occupied area.
2. Aeration strength is lower than the activated sludge method, and no sludge back, it can reduce the power consumption and simplify management.
3. Less sludge, reducing sludge dewatering and other post-processing workload.
4. The sludge generated by the settlement is good, conducive to remove suspended solids of end part.
5. Good adaptability, can adapt to a wide range of different water quality, have strong endurance of water quality to maintain a stable treatment effect.
