Zero Liquid Discharge (ZLD) is a wastewater treatment process in which all wastewater is either recycled or evaporated, thus leaving zero liquid waste to be discharged. The purpose of a Zero Liquid Discharge System is to produce clean reusable water and safely dispose of wastewater. Thus, minimizing disposal costs, and reducing your environmental footprint.
A Zero Liquid Discharge (ZLD) System Saves Money.
Every industry produces different types of wastewater each with unique challenges. Met-Chem has the expertise, experience, and technology to treat a wide variety of wastewater. Achieving Zero Liquid Discharge is accomplished through water purification, evaporation, and sludge dewatering. Met-Chem offers various systems for water purification including Ultrafiltration (UF), Reverse Osmosis (RO), and Deionization (DI). Met-Chem manufactures both Thermal Evaporators and Atmospheric Evaporators. Sludge dewatering is handled by a Met-Chem Filter Press.
Met-Chem can design and manufacture a complete Zero Liquid Discharge System for your company. Please contact Met-Chem to discuss preliminary planning, environmental goals, feasibility, and ROI.
Specific Industrial Wastewater Treatment will vary greatly. Met-Chem can design a Zero Liquid Discharge System to fit your needs.
The first step in achieving Zero Liquid Discharge is to pretreat the wastewater if required. This may be needed to remove certain toxins, and reduce the number of Total Suspended Solids (TSS). This step will also help to preserve the life of the Reverse Osmosis (RO) or Ultrafiltration (UF) membranes.
In this step, the wastewater is purified to the level of reuse. Some industries require ultra-pure water (UPW), and other industries only require potable water. Met-Chem will purify the water to the level your company needs.
Any wastewater that cannot be purified will be transferred to a holding tank to be processed. The wastewater is pumped into a heated tank system where the evaporator will evaporate the water. The wastewater will concentrate. The concentrated slurry will then be pumped into a Filter Press to capture the solids. The filter press will also keep the heated tank clean and provide a seamless operation.
In the final step, the filter press will capture solids, and return the remaining liquid for evaporation. The solid waste is discharged into a Sludge Cart where it can be properly disposed of in a landfill. In some cases, the solids can be sold or processed for reuse.
Met-Chem can manufacture a Zero Liquid Discharge Treatment System. The Evaporator and Heated Tank System can be manufactured with a gas-fired burner, steam coil or electric heater. Each Filter Press will be designed to your specifications. The manifold and piping can be constructed using, but not limited to CPVC, Carbon Steel, or Stainless Steel. As your operation grows, our filter presses can be expanded by adding additional Filter Plates, reducing the need to purchase new costly equipment.
An Atmospheric Evaporative Tank is an excellent solution for wastewater reduction and Water Evaporation. It is free of complicated machinery and chemistry, and it can actually save you money.
Those looking for the greatest evaporation rates at a given temperature will choose an atmospheric evaporator for its high efficiency.
Dewatering of waste solutions can save the users of evaporative tanks thousands of dollars in disposal costs. Where the need is for only 3 to 4 gallons of evaporation per hour, no added heat is required. Heat for evaporation is taken from the room.
