Landfill Leachate is created by liquid that drains or leaches from the landfill and needs to be treated as there can be materials that are dangerous to enter the sewer system and need to be treated prior to discharge. Rainwater is also a large contributor to the Leachate.
Landfill Leachate can be a challenge to treat, because it may contain a wide variety of wastewater. Met-Chem will custom build a Wastewater Treatment System specifically designed for your wastewater. Met-Chem is capable of treating standard Leachate with the physical treatment of polymers and precipitation, or more complex wastewater treatment with BOD (Biologically Oxygen Demand) and Activated Sludge.
A Met-Chem Wastewater Treatment Analysis will allow us to design and engineer a WWT (Wastewater Treatment System) to treat your exact wastewater. This allows us to provide the most cost-effective way to treat wastewater, and avoid the purchase of unnecessary treatment equipment to safely discharge the water.
Contact Met-Chem and discuss your Leachate and Wastewater Treatment Options.
Landfill Leachate is created by liquid that drains or leaches from the landfill and needs to be treated as there can be materials that are dangerous to enter the sewer system and need to be treated prior to discharge. Rainwater is also a large contributor of the Leachate.
Two types of systems are used for this treatment. The first is for applications where the pH is within a suitable range for discharge to the sewer system. This Leachate and rainwater will go into a large holding tank. This allows the landfill to handle the surges of Leachate it will see when there is heavy rain and allow the clarifier to handle an average treatment flow. The water will go from the large holding tank into the polymer section of our clarifier. Polymer will be added to help drop out the solids so they can be collected in the bottom of a clarifier cone. The clean water will exit the top of the clarifier and can go to the city sewer. The sludge in the bottom will be pumped through a filter press to further dewater the solids.
The second system is when your Leachate pH range is outside what is acceptable for discharge to the city sewer. For these cases after the large holding tank will be a dual pH adjust system. After the pH is adjusted the leachate wastewater will be processed through the clarifier and filter press.
A Met-Chem Clarifier is custom engineered and designed to fit your specific needs. Clarifiers come in a range of sizes and styles. The Met-Chem 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 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.
The Filter Press uses pressure filtration to separate the solids from the liquid. The slurry is pumped into the filter press where the solids mass is captured between the filter plates. The filtered water is returned to the holding tank.
A Met-Chem Filter Press is custom engineered and designed to fit your specific needs and application. Filter presses come in a variety of sizes ranging from 470mm to 1500mm, or 1 to 300 cubic foot capacity. The manifold and piping can be constructed using CPVC or Stainless Steel. Ask Met-Chem about additional filter press options and features.
