Chandrashekar S, Shankar HS: Bio-Remediation of Waste Water Streams using SBT: AICHE 2009
CAMUS-SBT is designed with minimal mechanical equipment
Frequently Asked Questions• What is the extent of pre-treatment? (How much COD, TSS and TDS are removed)
• Fine screens and Grit removal chamber• Equalization tank balances peak flows • Pre-Treatment Primary Clarifier / Tube Settler for BOD and TSS separation• Removal efficiency of 60% is in BOD and TSS in the clarified stream • Clarifier sludge is processed in a Anaerobic Digestor with Phosphate Accumulating Organisms (PAO)• Digested sludge further vermicomposted in BM3 to produced phosphate rich organic fertilizer
• What is the range of fluctuating load• CAMUS-SBT plants are designed as per CPHEEO norms as regards to peak flows• Plants are designed to handle flows from 5% to 100%• Shock loads of 30% over design load can accommodated for 1-2 days (requires extra consumables)
• flocculant/coagulant dosing to capture more TSS/BOD/COD and load on Bio Mounds • Feed rate or loading rate i.e. Hydraulic and Organic loading rates at each stage?
• Fine Screen and Grit Chambers are Designed at Peak Hydraulic Flow• Equalization Tank at CPHEEO norms of 2 hours at peak flow• Clarifiers at Average Hydraulic Flow using 1.5 cum/sqm/hr overflow rate• Anaerobic Digestor designed at 10-20 days detention time • BioMound 1 Hydraulic Loading Rate = 0.1 cum/sqm/hr (2.4 cum/sqm/day), COD loading rate = 0.35
kg/cum/day• Bio Mound 2 designed at Hydraulic Loading Rate = 0.2 cum/sqm/hr (4.8cum/sqm/day), COD loading
rate of 0.30 kg/cum/day 24
Frequently Asked Questions• What happens to the CAMUS- SBT plants in Monsoon?
• Rain water impinging on the Bio reactors will percolate down rapidly and captured in treated water.• Bio reactors are designed for hydraulic percolation rates of upto 5 cum/sqm/day • Heaviest 1 day rainfall ever recorded worldwide is 2.5 cum/sqm/day (Reunion Island)• Cherrapunji on average gets approximately 0.8 cum/sqm/day in monsoons• Overflow in Collection tanks ensure that the Bio Reactor/Bio Mounds is not flooded.
• What is the input and output of the CAMUS-SBT?• CAMUS-SBT plants are designed to meet CPHEEO/Client requirements for a given output.
• A comparative study of technology with respect to area and costs• upto 1 MLD,1-5MLD, 5-10 MLD, 10-50 MLD etc?
• Please see Technology Cost Slides• How are phosphates are removed in the CAMUS-SBT System?
• Phosphate removal takes place largely in Raw Sewage Tank / Clarifier / Anaerobic digestor by flocculation/coagulation/settling/bio accumulation via Phosphate accumulating organisms.
• Small amounts of Lime (pH management)+FeCl3 is added in the Raw water tank that precipitates the Phosphates as HydroxyApatite. pH of 6.5-7.5 is maintained
• In Larger plant the bottom phosphate rich sludge from Clarifier/Settlers is pumped as slurry to BM3 and is converted to vermi compost.
• In smaller plants the inorganic sludge at the bottom of Raw Sewage tank is periodically harvested (Once in 4 years)
• The biomounds themselves remove approximately 2mg/L 25
