Industry solutions for WASTEWATER

Tractor Painting Wastewater Treatment

Tractor Painting Wastewater Treatment – A renowned tractor painting company, with facilities across the United States, reduces wastewater treatment costs in a facility based in Georgia. Clean Water Technology’s patented GEM® System, followed by a membrane bioreactor (MBR) and a reverse osmosis (RO) system.

Tractor Painting Wastewater Treatment Solution by Clean Water Technology.

Our heavy metal industry case study client is a large and diverse company with facilities across the United States ranging from engine and tractor manufacturing to assembly and distribution. This company pioneered the sub-compact tractor in the market.  Needing to live up to their moto, “For Earth, For Life” the company researched total wastewater treatment systems for a facility in Georgia and chose Clean Water Technology (CWT-Global) as their wastewater treatment supplier.

They also need to consider:

The company needed a total wastewater treatment system for a new plant they were building.  

This tractor painting facility had wastewater with high total suspended solids (TSS), high chemical oxygen demand (COD,) and turbidity.  In addition, the water stream characteristics included paint and part cleaning wastewater and contained high levels of heavy metals.  The company wanted a complete system that would allow the wastewater to be reused.

Solution

Tractor Painting Wastewater Treatment Solution – Clean Water Technology (CWT–Global) proposed a primary wastewater treatment system (GEM® System 75/150), followed by a membrane bioreactor (MBR) and a reverse osmosis (RO) system. 

Upon commissioning, the flow rate was expected to be 65,000 gallons per day (GPD) and would be processed at 90 (GPM) gallons per minutes. 

Maximum flow rates were expected to be 150 GPM.  Since the GEM system can be re-calibrated to operate at flows below 75 GPM and up to 150 GPM, overall wastewater treatment capacity can be increased without additional capital expenditure. 

The GEM System effluent is fed into a Membrane Bioreactor (MBR) resulting in an effluent that complies with criteria for recycled water in California (title 22), and other jurisdictions for water reuse, including cooling tower water, plant washing, irrigation and other non-potable uses.  The Reverse Osmosis (RO) further purifies the water for additional uses.

Conclusion

Tractor Painting Wastewater Treatment Solution – Unlike conventional DAF technologies, the GEM System utilizes a unique combination of mechanical and chemical mixing to remove TSS and FOG and reduce undissolved BOD/COD.

The GEM System is not inhibited by contaminant loading. A single GEM System can treat 200 or 10,000 ppm of FOG and TSS while providing superior results within the same small footprint.

Utilizing a series of hydrocyclones known as Liquid Solid Gas Mixing (LSGM) Heads, the GEM System proactively separates the solids from liquids before they enter the GEM flotation tank. The LSGM’s serve three significantly unique purposes:

1) They provide homogeneous mixing of liquid contaminants and chemistry resulting in the attraction of more waste particles per polymer

2) They offer the flexibility to change the mixing speed and energy to adapt to Client’s unique wastewater characteristics and changing wastewater conditions

3) The saturation of 100% of the wastewater stream with dissolved air creates bubbles of various sizes to attract both the largest and smallest of waste particles.

As such, the GEM flotation tank is significantly smaller than most DAF flotation tanks as it is used only to skim the large, decantable solids that come off the beach at 10-13% moisture content with continued decant to often more than 30% solids.
