Sus316l Water Treatment Sedimentation Tank Lamella Clarifier Separator

SUS316L Water Treatment Sedimentation Tank Lamella Separator

Lamella clarifier uses the time proven concept of inclined plate clarification. This type of clarifier uses gravity in conjunction with the projected settling area of the 55-60 degree angle plastic parallel plates to settle solids from the pre-treated liquid flow. This treated liquid flows first to the flocculation tank where a polymer is added to promote floc growth, then down to the bottom of the clarifier and up through the plate pack(s) while the solids settle out to the bottom sludge cone or cones – depending upon the size. The solids are intermittently taken from the bottom cone tank for a further settling of the solids and then, finally to a filter press for final dewatering.

How does Lamella Separator work?

Lamella sedimentation separates solids from a carrying liquid by directing the material between a series of inclined plates (sometimes referred to as lamellae).

The plates, arranged in close proximity, divide the lamella tank into several integral sections or chambers. Only one side of each chamber, the top surface of a plate, provides a settling surface.

The pretreated feed stream enters the lamella tank and transverses through feed ducts longitudinally, along each side of the lamella plates, through a bottomless distribution duct.

The liquid and solids feed stream then enters each plate chamber near the bottom section of the plates and flows upward between them.

As the feed stream moves upward, solids settle downward by descending a short distance onto the surface area provided by the plates.

Solids continue to slide down the plate surfaces to a collection hopper.

Lamella Separator Applications

• Primary clarification of wastewater streams

• Backwash water recovery

• Industrial water treatment systems

• Potable water treatment systems

• River water abstraction clarification

• Wash water recovery and recirculation systems

• Wet scrubber and slaking effluent treatment

Lamella Separator Advantages

Durable stainless steel construction:

• Optimised solids settling using stainless steel plates with a smooth mill finish, ensuring no plate clogging or sludge build-up.

• Low maintenance; only a hose down required.

• Minimisation of thermal current and wind effects on settled water quality

Lamella Separator Continuous operation

• Due to its small volume no need to allocate large storage when emptying.
• No drive nor mechanical parts.
• Filling and emptying time is short.
• Small floor area footprint.
• Modular design for future expansions.
