HKPC-STSA Packaged Sewage Treatment System
BackgroundSewage treatment system, HKPC-STS, is apackaged system designed for treating toiletwastewater (sewage) in some specificlocations where are unable to discharge tosewer, e.g. rural schools, campsites, etc2
IntroductionCommon TreatmentMethods Discharge to sewer (ifavailable) Mobile toilets and tankeraway of sewage periodically Septic tank and soak awaypit3
Technical DetailsDesign Basis Influent Standard– No. of people served : 50 200– Influent flow: 3 12 m3/day– BOD5: up to 250mg/L– COD: up to 400mg/L– SS: up to 400mg/L Treated Effluent Standard (storm drain, etc.)– BOD5: 20mg/L– COD: 80mg/L– SS: 30mg/L4
Flow SchematicHKPC-STS5
Treatment Process HKPC-STS consists of an anaerobic chamber, an aerobicchamber and a sedimentation and disinfection chamber. Wastewater from toilets is firstly discharged into theanaerobic chamber for digestion and decomposition Then the wastewater will be overflowed into the aerobicchamber for the aerobic treatment process. Soluble andsuspended organic matters in the wastewater are absorbedand assimilated by the microorganisms growing on thesurface of the fill media. Finally, wastewater will enter into the sedimentation anddisinfection chamber for final sedimentation and disinfection.6
Technical Features Flexible in site installation. System can be floormounted, buried wholly or half-submerged. Made of FRP. Light weight, high strength, anticorrosion and high durability. Simple, continuous and automated operation. Low noise, less odor and less sludge generated. Excellent treatment performance.7
Application Area The HKPC-STS has three standard models tosuit different inflow rate and different sizes ofconstruction site to comply with generaleffluent standard for discharge to storm drain,etc.): Model dayDimensions2.0 X 2.7 X 2.3 m2.0 X 3.9 X 2.3 m2.0 X 7.2 X 2.3 m8
