Massachusetts Metal Recycling – Industrial Stormwater

Unlike many states that administer their own industrial stormwater programs, stormwater discharges at industrial facilities in Massachusetts are regulated under the Multi-Sector General Permit (MSGP) and administered by the Environmental Protection Agency (EPA). This metal recycling facility came to WaterTectonics for assistance with reducing Total Suspended Solids (TSS), heavy metals (Copper, Iron, and Zinc), and Chemical Oxygen Demand (COD) in its stormwater discharges. WaterTectonics had worked with this client many times in the past, and a process solution had already been identified for the facility to match operations at another like facility. However, this facility was in a colder region, and the client wanted to ensure the system could operate with minimal disruption or damage during the winter months. WaterTectonics provided a system utilizing electrocoagulation, settling tanks, media filtration, and carbon filtration. At 600gpm, the media filtration and carbon filtration systems were constructed in their own 40’ shipping containers and pass-throughs were built between the containers so operators could traverse the three-container system without having to exit and enter each box separately.
