This month we are focusing on the control of sludge blanket build up in Lamella Clarifiers. Lamella Clarifiers, also known as Inclined Plate. The efficient design of the SuperSettler™ lamella-type plate clarifier utilizes lamella plates and shallow depth sedimentation to minimize the clarifier footprint. The Monroe lamella plate Vertical Clarifier is designed to provide low cost, efficient solids removal from a wide range of waste and process liquids. The inclined.

Rather than the effluent flowing over the top of the inclined plates to the outlet channel it flows through orifices at the top of the plates. The clarifieg monitors provide an exceptionally simple and reliable method of detecting the sludge blanket level in clarifiers. Obviously this design only works for relatively clean effluent streams as the orifices would quickly become blocked with deposits which would severely reduce the efficiency of the unit.
Handbook of water and wastewater treatment technologies [Online-Ausg. By reducing the settling distance dramatically, higher flows can be treated in a much smaller footprint.
Lamella Plate Clarifier
Retrieved from ” https: Another design variation, which improves the efficiency of the separation unit is the way the effluent enters the lamella clarifier.
Some possible design characteristics include:. The sludge is drawn off at the bottom of the hoppers and the clarified liquid exits laella unit at the top over a weir.
Regular maintenance is required as sludge flows down the inclined plates leaving them dirty. Introduction to potable water treatment processes.
The retention time is the average time that a particulate remains in lmaella clarifier. The post-treatment required for the overflow stream depends both on the nature of the inlet stream and what the overflow will be used for.
Up to 10 m 2 of settling area per square metre of ground area Can be supplied as a complete unit for easy installation Available in standard and site-specific versions Minimal operating and maintenance costs. This design allows for more consistent back pressure in the channels between the plates and hence a more consistent flow profile develops. Lamella clarifier performance can be improved by the addition of flocculants and coagulants.
Advice on sensor selection is available by contacting our Sales Engineers. Inclined plates may be based on circular, hexagonal or rectangular tubes. Standard clarifier design has the effluent entering at the bottom of clarrifier inclined plates, colliding with the sludge sliding down the plates.
Further lamella clarifiers are able to maintain the required water quality to the membrane without the use of chemicals. Parallel Plate Settlers Report.

Novel application of a lamella clarifier for improved primary treatment of domestic wastewater. Our sludge blanket sensors can be designed into the Lamella Clairifier or retro-fitted, the low cost addition to the clarifier can save money on maintenance, avoid pollution problems and improve the quality of the sludge that is being extracted from the tanks.
They are used in industrial water treatment. Expected separation efficiencies for a typical unit are:. Effluent enters the Lamella Clarifier via an inlet pipe, entering the plates through the side openings where the liquids and solids are then separated.
Up to date news on products, events and industry insights from Partech Instruments. In such a case it often needs to be transported to a disposal plant, and the cost of this transport depends on the volume and weight of the slurry.
Higher values for turbidity removal efficiency correspond to less particulates remaining in the clarified stream.
