Steel Industry Experience: Representative Projects and Systems

Circular Clarifier to remove TSS/fines for blast furnace wastewater

Circular Clarifier to remove TSS/fines from blast furnace scrubber wastewater. The 46 ft. diameter clarifier was elevated on legs for ease of access to sludge piping, and was designed to handle a 2,000 GPM max flow.

Circular Clarifier for oil water separation

Circular Oil Water Separator for primary treatment of waste oils and solids at a steel mill. The 50 ft. diameter clarifier was designed with low sidewater depth, inlet diffusion, and multiple skimming arms & collection troughs.

900 GPM API Separator for oil water separation

900 GPM API Separator for free oil separation prior to a DAF. The system featured inlet diffusion reaction jet baffles, chain & flight conveyor, and customized oil skimming system with collection beach & auger trough.

Circular Clarifier for the clarification and thickening of the blast furnace scrubber wastewater

100 ft. diameter high-torque Thickener Clarifier treating blast furnace scrubber blowdown. The system included an inlet well flocculator, 500,000 ft·lbs drive torque rating, PLC controls, redundant sludge pumps, and a 15 mg/l effluent TSS and 5% solids underflow performance guarantee.

Dust Collector for dust collection of scale and steel fines from grinding operations

10,000 CFM Dust Collector Cyclone to remove scale and steel fines from grinding operations at a steel plant. System design included ceramic lining for abrasion resistance, 90% alumina ceramic tiles, and cone hopper w/ rotary airlock.

Belt Skimmers for oil recovery from wastewater

Monroe 8A Belt Skimmers for oil recovery from wastewater tanks at a steel mill. The custom thermoplastic belts are rated to withstand 180°F liquid temperatures.

Horizontal Plate Clarifier to remove TSS from pickling wastewater.

40 GPM Horizontal Plate Clarifier to remove TSS from pickling wastewater prior to membrane filtration. The polypropylene clarifier was equipped with chemical mixers, HDPE separation plates, and surface oil skimmer.

Lamella Plate Vertical Clarifier for treating metal finishing wastewater

Lamella Plate Vertical Clarifier to remove iron and nickel hydroxides from metal finishing wastewater. The 1,533 GPM unit was constructed of 304 SS, equipped with flash mixing and flocculation tanks, and provided over 3,900 ft2 of settling area.
