In a society where capex is less abundant and effluent permits are more stringent, there seems to be no treatment solution known that can overcome these challenges. However, a new technology is being introduced to the market that can alleviate both of these concerns.
Xylem – Sanitaire Taron, Rotating Disc Dynamic Filter (RDDF) combines secondary clarification and tertiary filtration in one complete step. Taron’s design consists of a modular configuration comprised of vertically rotating mesh panels. Filtration occurs as the partially submerged panels rotate slowly in the bioreactor depositing biomass on the mesh. The hydraulic pressure then compacts the biomass via gravitation forming a sludge cake layer comprised of finely sized pores. This drives quality effluent with TSS concentrations less than 5 mg/L and turbidity levels below 10 NTU. The sludge cake layer is removed after each rotation via a backwashing system, eliminating the risk of mesh plugging. The sludge is then returned to the bioreactor permitting a higher operation of MLSS in the bioprocess. Taron’s utilization of sludge cake layer build-up allows it to thrive at high MLSS concentrations from 4,000 – 15,000 mg/L; this also enables Taron to operate at flux rates of 588–1,200 gfd (1,000–2,040 lmh). Operating at these high MLSS concentrations allows for plants to maximize their biological capacity while reducing the footprint required for the wastewater treatment process – thus, contributing to a mass savings in capex.
In this session we will explore Taron’s ability to achieve quality effluent while saving on capex budgets – making it the ideal treatment solution in today’s society.
