Tube Settler System:

• Conventional clarification equipment requires 10 times more physical area to even begin to approach the same settling capacity of a Neotech Lamella Gravity Settler. This means faster settling in one-tenth space because the effective gravity settling area of the inclined plate design equals each plate are projected on a horizontal surface. Up to ten square feet of settling area becomes available for each square foot of physical area occupied by the unit. Loading rates normally used for the design of conventional settlers can be applied to the sizing of a Lamella Settler by substitution projected area for the surface settling area of a conventional clarifier.
• The compact design minimizes hydraulic disturbances caused by wind or temperature changes. Balanced flow distribution ensures equal flow to each plate and across the plate surface area preventing short-circuiting.
• Units and plate packs arrive at the job site factory assembled which reduces installation time and lowers installed costs. Minimal moving parts mean low maintenance costs.

How it Works:

• Influent enters the lamella system and flows downward through the inlet chamber in the center of the unit and enters the plates through side  entry plate slots. The countercurrent design, unlike typical bottom feed designs, reduces the risk of disturbing previously settled solids. As the liquid flows upward, the solids settle on the inclined, parallel plates and sludge into the sludge hopper at the bottom. Further thickening of the sludge is achieved in the hopper due to compression in the quiescent zone achieved by the side feed design.
• The clarified liquid leaves the plate assembly through orifices or weirs at the top and is distributed into the collection channels leading to the clarified water outlet. This creates a pressure drop across the collection channels which ensure uniform flow distribution across the plates in order to utilize the full area for settling.

• No moving parts, thereby minimizing maintenance
• Continuous operation possible for any length of time without shutdown
• Each plate is constructed of FRP corrosion resistant material
• Lifting arrangements are not required for plate installation or inspection individual Lamella plates can be easily removed and installed during installation or maintenance by a single operator without
• the need to shut down the system
• Internal flow feed ducts ensure even distribution of water to each and every plate
• controlling velocity and thereby minimizing turbulence
• Adjustable weir plates ensure even collection of the treated water without short circuiting
• The tank and structural support design is completely self supporting for continuous working
• conditions and is also compatible with supporting walkways, ladders etc.
• The flash mix cum flocculation tank is a one piece configuration for bolt up to the lamella tank in the field.
• The Lamella Clarifier system design is such that it does not build up deposits, thereby minimizing the frequency of cleaning as well as other maintenance problems usually faced with conventional clarification
