“ANC” Advanced Wastewater Treatment System

Across various industrial and municipal wastewater sectors, stringent nitrogen limits and the presence of refractory organic compounds make stable compliance difficult, leading to frequent operation and maintenance interventions and process upsets. Conventional treatment trains often rely on external carbon dosing, intensive aeration and membrane polishing, resulting in high energy consumption and elevated costs. To address these challenges, HKPC has developed “ANC System”, an advanced Anammox Chemical Co Treatment Process that integrates our proprietary advanced chemical precipitation with the Anammox process to deliver excellent carbon and nitrogen removal performance with significantly lower energy use, chemical demand and overall operating cost.

Service Details:
  • Applicable to high ammonia and recalcitrant organic wastewater from various industries such as landfill leachate, electroplating, semiconductor, chemical, livestock, food waste leachate, sludge digestate, etc
  • Uses HKPC patented chemical treatment process to precipitate colored and non-biodegradable organics
  • Low carbon Anammox process removes nitrogen efficiently
  • Chemical precipitation effectively removes humic substances and inhibitory components to significantly alleviate their toxic effects on Anammox bacteria, thereby enhancing system stability and applicability
  • Achieves 90% color removal, >70% organic (COD) removal, and effluent nitrogen levels of NH3 N <1 mg/L and Total Nitrogen <30 mg/L
  • Compared to conventional processes:
    • Zero external carbon addition
    • About 85% lower power consumption and up to 90% lower carbon emissions
    • Up to 25% lower capital investment (CAPEX) and 75% reduction in operating expense (OPEX)
  • Applicable as a green, efficient and scalable solution for complex industrial and municipal wastewaters with high ammonia and poorly biodegradable organics, reducing energy use, carbon footprint and total cost while improving treatment stability and compliance assurance
