Tyco Fire Protection Products relied on evaporation technology for wastewater treatment and volume reduction. The operation was extremely messy. Liquid waste streams were collected in secondary containment units on the shop floor and were moved to the outdoor evaporation area. The outdoor evaporation area was often cluttered with various containers of waste until the evaporation cycle was complete and another batch could be processed. The operator was required to transfer material from the waste container to the evaporator using pumps and hoses. This process resulted in frequent spills, overflows, leaks and drips. Secondary containment structures were strategically placed around the waste transfer operations; however, the spilled material would have to be evacuated, the secondary containment structure cleaned, and the containment put back in place. The evaporator reduced the liquid volume about 70% resulting in a gelatinous substance. The sludge-like material would have to be evacuated from the evaporator with a system of pumps and hosed and containerized in drums for disposal. Overall, the waste stream had to be handled twice; once to place the material in the evaporator and a second time to evacuate the material from the evaporator. Material handling was cumbersome.
Tyco installed a new wastewater treatment system that allows for the regeneration of wastewater. Water from parts washing centers is recycled. Prior to installing the engineered WWT system, the wastewater generated from the parts washing process was discharged directly to the POTW after a single use. Ultra-filtration technology allows the water to be reused.
Total Cost Savings: $56,000.00
Comments: The payback period of the project is 2.5 years. Total cost savings due to avoided disposal are $30,000/year. Cost savings for material handling overall are about 900 labor hours which is about $18,000/year.
