Metal Recycler, CA
Atlas Iron and Metal Company, California
Atlas, a family run organization since 1949, is one of the leading buyers of steel, cast iron, aluminum, stainless steel, copper, brass, radiators, insulated wire, electric motors and all other metals in the Los Angeles area.
The company installed a StormwateRx treatment train including Clara and Aquip in 2010 to comply with the California Industrial General Permit.
TARGETED POLLUTANTS: TSS, COD, copper, iron, aluminum, zinc
Atlas Iron and Metal Company is a scrap metal recycling facility on the Alameda Corridor in Los Angeles, California. Atlas, a family run organization since 1949, is one of the leading buyers of steel, cast iron, aluminum, stainless steel, copper, brass, radiators, insulated wire, electric motors and all other metals in the Los Angeles area.
Southern California, while dry for the majority of the year, has seasonal downpours that can flood low lying areas. Atlas’ location was no exception. As scrap recyclers it is not uncommon for them to see heavy oil from engine blocks, grease, particulates or suspended solids (known as TSS in the stormwater community), metals, and COD (chemical oxygen demand). Despite the company’s efforts to control pollutants on site through rigorous source control and housekeeping BMPs they still had concerns that some pollutants were making their way into local waterways.
With the help of StormwateRx LLC Atlas revamped their entire stormwater conveyance system to reduce pollutants from leaving their site and entering in local waterways.
StormwateRx has helped redesign the stormwater conveyance so that all stormwater leaves the site through the treatment BMPs. StormwateRx supplied the Clara Plug-Flow Separator for pre-treatment of stormwater and the Aquip SBE Filtration System for enhanced treatment.
Clara Plug-Flow Separator is a settling system that provides basic or first line removal of free-oil, floatables, dirt and associated pollutants such as metals. Clara includes an internal high flow bypass that allows storm events larger than the treatment design capacity (i.e. – clean water) to bypass without washing out accumulated oil and sludge.
Aquip enhanced stormwater filtration system provides a secondary level of pollutant reduction targeting fine solids, dissolved metals, nutrients and organics. The patented Aquip uses filtration, sorption, and biological processes as the primary means of pollutant removal. Solids and metals (dissolved and particulate) are sequentially removed within the Aquip after passing through several layers of both inert and sorptive medias. The Aquip also targets the removal of organics (known as COD, BOD, and TOC) using biological activity inherent to the depth filtration system. The Aquip’s passive hydraulic controls provide optimal pollutant removal without using water backwashing systems as required by pressure sand filtration systems.
With the help of StormwateRx, Atlas revamped their entire stormwater conveyance system and added an end of pipe stormwater treatment system to reduce pollutants from leaving their site in compliance with the California Sector-Specific Scrap Metal Recycler NPDES Storm Water Permit.
