Product Description
Lamella clarifier for waste water partical settling
Brief introduction
It is kind of high efficient combined type settling tank; set many dense inclined tube packing in sediment area, to make the suspended impurity in water sediment.
Such tank can improve sediment efficiency 50~60%, it can improve treatment capacity 3~5 times in the same area. It can design different flow rate inclined plate sediment device according to raw wastewater test report, it need dose flocculant usually.
Specification model YMXG | XG-5 | XG-10 | XG-15 | XG-20 | XG-25 | XG-30 | XG-40 | XG-50 | |
capacity (m3/h) | 5 | 10 | 15 | 20 | 25 | 30 | 40 | 50 | |
Size (m) | 2.2*2*3.5 | 2.25*2.25*5 | 5*2.5*4 | 6*3*4.5 | 8*3*4.5 | 8*3.5*4.5 | 10*3.5*4.5 | 12*3.5*4.5 | |
Working process
- Waste water flow into flocculation tank after add coagulant aid
- Waste water flow into lamella clarifier by feed box
- Waste rise flow along inclined tube,suspended impurity in water settle down.
- The separated sludge down to the tank bottom along the inclined tube by gravity,then discharge by sludge hopper.
- The clean water rise flow along flow distribution orifices and concentrate in discharge flumes
- When the water is enough ,they will overflow ,then realize the separation of solid-liquid.
The advantages
- Simple structure,without wearing parts,wear well,decrease maintenance
- Steady operation,easy operation
- Up to 10 m2 of settling area per square metre of ground area
- Small power,save energe
- Small occupy area, low investment, high efficient. Space requirement can be reduced by up to 90% when compared with a settlement tank
- Short retention time, high sediment efficiency, no sludge backflow.
- Supplied as a complete unit for easy installation

Products details
Inclined tube structure introduction
1. Inclined tube material: PVC,PE,PP ,inclined plate: carbon steel
2. The cleaning water area height is 1.0-1.5m above the inclined pipe top,the water distribution zone below the bottom no less than 1.0-1.5m, mechanical discharge sludge, the water distribution zone height should more than 1.6m, convenient install and maintenance.
3. The Re number in water flow less than 500,Fr number is 10-3—10-5 in inclined pipe.
4. Inclined tube design flow rate is 1.0-4.0mm/s, inclined plate 10-20mm/s.

Advantages
1. Simple structure,without wearing parts,wear well,decrease maintenance
2. Steady operation,easy operation,small power,save energe,Footprint reduce about 90% compared with a settlement tank.
3. Up to 10 m2 of settling area per square metre of ground area
4. Short retention time, high sediment efficiency, no sludge backflow.
Application
- Electroplate effluent contain many kinds of metal ion, Cr,Cu,Fe,Zn ,Ni etc remove rate all above 90%, after treatment, all can reach discharge standard.
- Coal mine,mineral processing waste water all can make the turbidity from 500-1500 mg/L reduce to 5 mg/L.
- Printing and dyeing,bleach and dye etc effluent chroma removing rate reach 70~90%,COD remove rate 50-70%.
- Tannery ,food etc industrial sewage COD remove rate 50~80%, impurity solids remove rate above 90%.
- Chemical waste water COD remove rate 60~70%, chroma removal rate 60~90%, suspended solids reach discharge standard.
