Lamella Clarifier

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

Efficient treatment of high concentrations of solid waste water grit  clay  lime  metal particles 

The smallest floor area  maximum capacity

Install both in indoors and outdoors  but the ambient temperature needs above 0 

Slope sedimentation tank can create a good laminar flow environment  to achieve better precipitation effect

Intensive design  minimize the hydraulic interference caused by wind or temperature change

Suitable for onsite unattended automatic continuous operation

Life time of carbon steel material 10 years  life time of stainless steel material 20 years

Supplied as a complete unit for easy installation

ADVANTAGES

Simple structurewithout wearing partswear welldecrease maintenance

Steady operationeasy operation

Up to 10 m2 of settling area per square meter of ground area

Small powersave energy

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 back flow

Supplied as a complete unit for easy installation

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
