During the Manufacturing Process of Corrugated Cardboard or Paper Mill Manufacturers. There are many steps in the process that produce wastewater. These wastewater streams contain various contaminants and solids, in which the wastewater will not be within range to be discharged to the drain.
Wastewater can be created from several different steps with pulp mills or the paper recycling process. Several examples include waste from the corn starch glue that is used to bond the corrugated material to the sheets, extra starch particles in the water, different waxes for specialty finishes, BOD / COD Wastewaters, wastewater from bleaching, or de-inking wastewater. Met-Chem has the technology and the industrial experience to design, build, and install the exact wastewater treatment system for each individual customer.
Many factors go into which wastewater treatment technology is chosen, but the overall volume of water to treat is always step 1.
Met-Chem can develop a custom-built wastewater treatment to treat your specific wastewater. A Continuous Flow Wastewater System can be designed for larger pulp and paper mills with more complex treatment. Smaller versions such as Batch Waste Treatment Systems or Evaporation System can be build for smaller manufacturers.
Met-Chem can also offer options for discharge and for water reuse.

Incoming wastewater from various streams are collected in the equalization tank. The main function and purpose of the equalization tank is to make the wastewater homogeneous, and it maintains the desired flow rate.
By adjusting the pH (hydroxide ion concentration) of the wastewater, metals become insoluble and they become easier to remove. Typically a two-stage pH Adjustment system is used to obtain a specific pH Target. The two-stage pH system is more economical and Saves on Time, Chemicals, and Money.
After the wastewater has had the pH adjusted, it will go into a clarifier, where polymer is added into the flocculation tank. Here the sludge settles to the bottom of the clarifier. Wastewater from the top of the clarifier can be safely discharged. While the sludge will be transferred to the Sludge Thickener Tank.
The sludge from the clarifier is collected in the Sludge Thickener. This sludge will be eventually processed by the Filter Press. Any overflow will be sent to the pump station.
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 filtered water is then sent to the pump station.

When your daily wastewater volume is not high enough to warrant a Continuous Flow Wastewater Treatment System then a Met-Chem Batch Wastewater Treatment System is the way to go. Our batch wastewater treatment systems range from 500 gallons per day up to 10,000 gallons per day.
Met-Chem can build a wastewater treatment system designed to fit your specific treatment needs.
If your wastewater flow rate is not high enough to justify a Batch or Continuous Flow Wastewater Treatment System, an Atmospheric or Thermal Evaporation System might be a better solution for your company. An Evaporation System can reduce your need to haul away Expensive Wastewater, and the equipment would Pay for Itself in a manner of years.
