Problem: An Arkansas developer wanted to build a subdivision outside the range of city sewer service. To maximize property development, at least 260 homes were needed on the 60-acre development, including wastewater treatment and disposal. A compact wastewater treatment system needed to maximize development and meet a 100-foot residential setback requirement. To save space, an NPDES surface discharge permit with stringent levels for BOD, TSS, oil and grease, COD, total organic carbon, ammonia and phosphorus was obtained.

Solution: FujiClean USA treatment systems were specified. Due to complex topography, a combination of gravity sewer and two lift stations were utilized to deliver wastewater to a central collection point at the corner of the development. The combined final treatment system includes at 20,000-gallon trash/alum dosing primary treatment tank, a 20,000-gallon settling/equalization dosing tank, 12 FujiClean CE6KG secondary treatment units offering 72,000 gpd total capacity, a 1,500-gallon discharge tank and UV disinfection. The modular FujiClean treatment system allowed the developer to control cost and infrastructure during the build-out. A common operator building was constructed to house the UV, alum storage, flowmeter and control panels. 

Result: The FujiClean systems were successfully implemented in the subdivision. 207-406-2927; www.fujicleanusa.com
