StormwateRx offers two approaches for higher flow rate sediment removal – a Clara Separator for free oil, floatables, and settleable solids removal, and Clara Filter for free oil, floatables, and suspended solids removal.

High Rate Filtration:

Clara Filter

Modular, High-Flow Removal:

Clara LongBox

Clara (KLAR-uh) Separator is a patented oil-grit-trash-water gravity separator for industrial stormwater treatment. This below-ground, standalone system is a high capacity oil water separator specifically designed for the fluctuating flow rates inherent to stormwater.  With the built-in internal high flow bypass, pollutants are trapped in this below-ground structure even during peak runoff events.

Clara (KLAR-uh) Filter is a patent pending†, passive media filter that can serve as standalone treatment or as a pretreatment BMP for sites with high particulate (TSS) loading. Clara Filter is specifically designed for filtration of runoff from site with erosion, or sites where the stormwater quality is close to benchmarks/numeric action levels.

Clara (KLAR-uh) LongBox (LB) Separators are designed specifically for efficient sediment, suspended solids and metals removal on stormwater treatment and dewatering projects and the treatment of process water, mine groundwater and wastewater. Easily transport on flat-bed trucks to sites and remote areas, installation, setup and operation are fast and simple with their small footprint, even on uneven ground. Available with tube settlers or inclined plates, Clara® LB® separators provide excellent removal efficiencies compared to traditional weir tanks and settling or frac tanks commonly used for sediment treatment on unpaved sites and in heavier industrial applications.
