Wastewater clarification technologies for primary and secondary treatment. Clarification and separation technologies remove suspended solids from wastewater, providing a clarified liquid effluent for downstream treatment processes. Clarifiers & Separators.

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 …

In the LAMELLA ® Gravity Settler, influent enters the unit and is distributed onto the plates through side-entry inlet slots. The side-entry design, unlike less efficient bottom feed designs, reduces the risk of disturbing previously settled solids and offers better effluent quality at higher plate loading rates.

The MAK Water Lamella clarifiers are capable of managing feed water with high concentration of suspended solids. Separation results will vary depending on the feed water quality and types of contaminants. The feed water enters the lamella clarifier through the inlet channel on the top and flows to the bottom of the separator.

Feed point: Feed should be introduced at least 20% above the base of the plate to prevent disturbance of the settling zones at the base of the plates. Post-treatment systems. Both the overflow stream and the underflow stream from a lamella clarifier will often require post-treatment.

The inlet stream is stilled upon entry into the clarifier. Solid particles begin to settle on the plates and begin to accumulate in collection hoppers at the bottom of the clarifier unit. The sludge is drawn off at the bottom of the hoppers and the clarified liquid exits the unit at the top.

LT – Lamella Thickener the Lamella thickener is a tank model available in several standard sizes. It is supplied with a ...

A Lamella Plate Settler uses parallel inclined plates to minimize floor area occupation. The size and cost of the settler can be reduced by matching the thickening and clarifying requirements more closely. Two basic criteria for gravity settling equipment to be met are sufficient clarity of the overflow liquid and maximum density of the ...

A typical Lamella Thickener plate is usually two feet wide by ten feet long, is spaced two inches from adjacent plates, and is inclined at an angle of 45 or 55 degrees. The ten foot plate length is divided into two sections, one above and one …

Thickening and clarifying. Poor solid-liquid separation functions can threaten the overall performance of your processing plant. With our efficient feed dilution and flocculation technology, we provide superior thickening performance in the form of better overflow clarity and higher underflow densities, while minimising your operating expenses.

Typical lamella clarifier design consists of a series of inclined plates inside a vessel, see first figure. The untreated feed water stream enters from the top of the vessel and flows down a feed ...

The feed enters the unit through the feed pipe and flows through the inlet chamber in the centre of the unit and in between the plates through ... The Lamella Thickener is a Tank model available in several standard sizes. It is supplied with a sludge thickening tank

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 ...

In the Ionic lamella clarifier, flow enters form both sides of the lamella plate. This allows the feed flow to be equally proportioned, directed and distributed to all settling surfaces without impeding the movement of solids already settled. The inlet flow is divided and enters the lower part

Lamella thickeners are high rate thickeners that use a series of angled impact plates to increase settling rates. The problems for the clients thickener were: When the bed level came up to high and entered the plate region the efficiency of the thickener dropped. The bed would sometimes break up and flow over into the launders.

Production and treatment of process and drinking water. Description of slurry thickeners ENVITES: As a standard, the slurry thickeners are produced in sizes with the tank diameters of 2.0 – 3.6 m and volumes of 5.7 to 39 m 3. The tank consists of a cylindrical …

An equivalent total depth of 42 ft of clays averaging 3.5% solids content were added, through a 308-day period, to the 7-ft pit. The final thickness of the clay bodies was 42 in, and the clay solids averaged 33.8%. The design of the experiment was aimed at creating a 400- to 600-lb/ft² pressure on the clay wastes.

Ovivo is synonynous with sedimentation, the mainstay process for liquid-solid separation. The range of settlement basin designs and sludge removal options available within our portfolio allow Ovivo to provide customized mechanisms suitable for any conceivable sedimentation application.

5.6.2.2 Center-feed, peripheral draw-off clarifiers shall not have the overflow weir against the clarifier sidewall. Weir placement shall be 1/10 diameter or greater toward the center. 5.6.2.3 The up-flow rate shall not be greater than the surface overflow rate at any …

Thickeners Particle size 0.1 to 300 im try to avoid using a thickener for particle diameters Downward solid flux of 0.2 to 500 g/s m with low values of 0.2 to 2 for waste water treatment, pickle liquor and higher values of 40 to 70 for mineral processing.Higher flux rates by factors of 3 to 10 up to fluxes of 800 g/s m can be obtained with the addition of flocculants.

The feed enters through vertical chambers on either side of the lamella packs, with clarification taking place above the suspension inlet so there is no mixing of the clarified fluid with the incoming feed. The solids hit the lamella plates and slide down to the sludge tank where they are thickened further and compressed using a raking system.

The Lamella Settler consists of 4 major compartments positioned along a rectangular settler tank with an inclined backside at a slope of 45-60 degrees. The sections are: A central slurry feed launder with a feed connection. Two plate pack compartments with overflow launders that straddle the feed launder.

pump the contents of the tanks to the 2 (No.) new lamella thickeners (duty/duty), whereby solids will gravitate into each integral thickener, and supernatant (clarified water) weirs then gravitates to the existing inlet chamber at the head of the works if <10NTU. If supernatant is >10NTU then flow will be directed back to the washwater tanks.

Conventional thickener feedwell designs have two main shortcomings: short circuiting, where the feed stream momentum carries the flow prematurely down and around the feedwell, past the shelf and deflector, and out of the feedwell; and inefficient flocculation, where only a small area around the inlet of the feed provides good mixing.

Energy consumption with lamella separators generally uses 0.1 kWh/m 3 to achieve an output concentration of 0.1–1.5% dry algal biomass ( Uduman et al., 2010 ). Algal recycling is an interesting strategy in which recycling algae with readily settleable algae strains, such as Pediastrum sp., improved settling efficiency by 85%.
