For sites where space is sufficient and suitable sand media is locally available,* Recirculating Sand Filters are a good method for bringing wastewater that varies in volume and strength up to advanced treatment levels: BOD & TSS levels below 10 mg/L and total nitrogen reductions of 40-50%.
Complete RSF kits from Orenco Systems can handle every onsite treatment need, from a 1,000-gallon per day installation to a million-gallon per day effluent sewer system. Typically installed at grade level, they're the ideal solution for treating commercial waste from restaurants, schools, or RV parks. Orenco RSFs require little power to operate, and there's no need for a full-time operator. An Orenco Recirculating Sand Filter makes sense when treatment quality is important and cost matters.
* For sites where there is no room for a sand filter or suitable sand is unavailable, AdvanTex Treatment Systems may be the best solution for advanced treatment.
