Met-Chem understands that various types of wastewater contain organic matter that needs to be removed. Biological Oxygen Demand (BOD) is a chemical procedure for determining the amount of dissolved oxygen needed by microorganisms to break down organic matter.
Since many industries are facing stricter regulations to treat wastewater, Met-Chem will engineer and manufacture Wastewater Treatment Equipment for your specific needs. Met-Chem is able to design a complete wastewater treatment system or retrofit your existing system.

There are various types of wastewater that require specific treatment. Met-Chem will engineer and design a custom system to fit your specific wastewater treatment needs.
Wastewater is collected in the Initial Settling Tank or the Primary Clarifier. The main function and purpose of the Initial Settling Tank is to make the wastewater homogeneous, and it allows for solids to settle to bottom of the tank forming sludge. The sludge collect is removed and piped over to the Sludge Thickening Tank. While the Setting Tank will remove much of the initial solids, there are organic compounds will not settle, and it will need to be treated in the Aeration Tank or a DAF Clarifier, depending on the specific application.
In a conventional BOD Wastewater Treatment process, microorganisms use oxygen to break down organic compounds. The microorganisms essentially consume the organic matter, but there must be enough oxygen in the water. If there isn’t enough oxygen in the water, the microorganisms will die. Diffused Air supplies the aeration tank with an ample amount of oxygen. The organic compounds in the wastewater provide the microorganisms their “food”.
Since microorganisms will multiply in the wastewater over time, it is essential to have the correct balance of Oxygen, Organic Matter, and Microorganisms. Imbalances will hinder efforts to treat the wastewater. Eventually, the wastewater will be transferred over to the secondary clarifier, where the excess microorganisms will be removed as Wasted Activated Sludge (WAS). A portion of the Activated Sludge will be returned to the aeration tank to supply the new wastewater with enough microorganisms.
After the wastewater is treated in the aeration tank, it is transferred to the Clarifier or the Secondary Clarifier. The Clarifier will remove the excess microorganisms (Activated Sludge), and the effluent (clean water) that flows to the top will be discharged or transferred for further polishing.
Over time the microorganisms and remaining solids will settle to the bottom of the clarifier which is referred to as Activated Sludge. A portion of the Activated Sludge is returned to the Aeration tank to supply a sufficient amount of microorganisms. The excess sludge or Waste Activated Sludge (WAS) is then transferred to the Sludge Thickening Tank.
The Waste Activated Sludge from the clarifier is collected in the Sludge Thickener. The thickening tank will provide additional solid-liquid separation. Any liquid overflow will be returned to the settling rank. The thickened sludge will be processed by the Filter Press.

When there is enough wastewater in the sludge thickener, the slurry from the tank is pumped into the Filter Press. The filter press separates the liquids and solids using pressure filtration. Sludge Cake will form between the filter plates, where it can be safely removed and easily discarded. The excess water is returned to the Initial Settling Tank.
Our Large Volume RO Systems are designed to purify 18,000 to 270,000 gallons per day of water reliably and at an affordable price.
Met-Chem manufactures wastewater treatment systems. Each wastewater treatment system will be custom designed for your specific needs. As your business grows, we can expand your current system, reducing the need to purchase a new costly system
Met-Chem can offer start-up and installation as an additional option. We can provide full support as you get your system up and running. We have installation technicians and technical representatives that we can send to your facility to make sure the system is running as it should.
All units and systems are complete with manuals and telephone support. However, if you need someone to come to your facility, we will be happy to quote you on that as well.
