Description

The Warminster Water Reclamation Facility (WRF) is a 31 m3/d wastewater treatment plant that faced challenges in nitrogen removal and sludge management while meeting stringent effluent limits. To address these issues, the facility adopted a modular solution combining the AvN™ control strategy, miGRATE™ biofilm carriers, and inDENSE™ sludge densification hydrocyclones. The AvN™ system optimizes total inorganic nitrogen removal by dynamically adjusting dissolved oxygen setpoints based on the ammonia-to-nitrate ratio to improve energy efficiency. The miGRATE™ carriers, composed of hemp fibers, polymer binders, and a natural densifier with high specific surface area, support biofilm biomass growth by migrating throughout the process for easy retrofit and simultaneous nutrient removal. The inDENSE™ hydrocyclones enhance sludge properties by separating lighter sludge for waste handling while retaining denser biomass, improving settleability and process stability.
