The Lamella clarifier is a device which can separate the solid in the water under gravity Its working principle is based on the shallow water theory sedimentation tanks sedimentation efficiency is only related with the sedimentation area In the lamella sedimentation tank the sedimentation area is the sum of the horizontal projection of all inclined plates doubling increase sedimentation efficiency
It is kind of high efficient combined type settling tankset many dense inclined plate packing in sediment area to make the suspended impurity in water sediment water rise flow along inclined tube the separated sludge down to the tank bottom along the inclined tube by gravity then discharge it in concentration Such tank can improve sediment efficiency 5060 it can improve treatment capacity 3to 5 times in the same area It can design different flow rate inclined plate sediment device according to raw waste water test report it need dose flocculant usually
Its widely suitable for the industrial waste sanitary sewage coal mine pit sewage the non ferrous metal processing waste water Power plant Boiler room water power dust removal waste water Liquid Solid of coal gas station washing Also suitable for the pretreatment of the water purify
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 tubesuspended impurity in water settle down
The separated sludge down to the tank bottom along the inclined tube by gravitythen 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 solidliquid
EQUIPMENT FEATURES
Capacity 1150 m3h

APPLICATIONS
Electroplate effluent contain many kinds of metal ion CrCuFeZn Ni etc remove rate all above 90 after treatment all can reach discharge standard
Coal minemineral processing waste water all can make the turbidity from 5001500 mgL reduce to 5 mgL
Printing and dyeingbleach and dye etc effluent chroma removing rate reach 7090COD remove rate 5070
Tannery food etc industrial sewage COD remove rate 5080 impurity solids remove rate above 90
Chemical waste water COD remove rate 6070 chrome removal rate 6090 suspended solids reach discharge standard
