Met-Chem - Model 30 GPM -Inclined Plate Lamella Clarifier
Inclined Plate Lamella Clarifiers are designed to remove solids from water. They are used in a wide variety of Wastewater Treatment Applications, including Metal Finishing Wastewater Treatment. The Total Suspended Solids (TSS) in the wastewater will naturally settle over time due to gravity, but this process can be sped up and improved by having Inclined Plates. The inclined plates provide a large projected settling area in a compact form. This technology is greatly beneficial compared to a cone bottom tank or a circular clarifier because of the space savings, settling efficiencies, and the reduced cost of construction.

Wastewater flows into the Clarifier at the top of the tank. Depending to help on the type of Wastewater Application you need, Flocculant and/or coagulants are added to help settle out the solids. The wastewater is fed via baffles to the bottom of the unit. This is where the settling process begins. Water flows up through the plates while the solids settle to the bottom of the clarifier.
After gravity settles the solids to the bottom of the clarifier, it is pumped into a sludge thickening tank for additional settling. From the sludge thickener, the sludge typically gets pumped through a filter press for final dewatering. The water from the filter press is returned back to the equalization tank, and the solids are safe for disposal.
Once the water is filtered and enters the top of the tank, it is typically safe for discharge. In some cases, additional water polishing is required.
Total Suspended Solids(TSS) will naturally settle over time due to gravity, but this process can be sped up and improved by having an Inclined Plate. Water flows up the plate at a 60° angle. Gravity will force the solids to settle onto the plate. The particles collect on the plates will become heavier and slide back down the plate to the clarifier cone. This process creates a counter flowing pattern, where the solids are seperated from the liquid into two lanes of traffic. The water flows in the upward bound lane, and the sludge flows in downward lane. This method reduces drag and friction creating a faster settling process than if the solids were to settle naturally.
FlocculantsandCoagulantsare added to improve the settling time.Coagulantsneutralize the negative charge particles allowing them to sink faster.Flocculantsallow for the small particles to collect and accumulate. This will make the solids heavier and easier to settle.
Inclined Plates allow for a compact design, therefore reducing the need for valuable floor space. The plates are angled at 60° allowing for an efficient projected surface area. Larger angles cast a smaller projected surface area, and shallower angles disrupt sludge flow and potentially could clog the plates. In the diagram, the Total Projected Surface Area graphically compares the equivalent floor space needed.One Standard Met-Chem Plate Pack is equivalent to a 15-foot diameter holding tank or a circular thickener.
Met-Chem’sdesign allows for a50-60 minute retention time. This is a much better retention time than a traditional Parkson Style Clarifier which has nearly half the retention time. By having a greater retention time, this allows for more settling time, which improves the counter flowing pattern as described above. Moreover, a larger retention timeReduces the Risk to Overrun the Clarifier.
