Hospital sewage carries pathogens, disinfectants, pharmaceutical residues and laboratory chemicals alongside normal sewage. We design STPs with robust biology, membrane or tertiary filtration and reliable disinfection — sized for beds, OPD load and future expansion.
A hospital generates 400–500 litres of sewage per bed per day plus OPD, staff and canteen loads; the stream includes disinfectants that can shock biology, laboratory and radiology waste (handled separately under BMW Rules), and pharmaceutical residues. Norms for hospitals emphasise faecal coliform and disinfection; treated water is commonly reused for flushing, landscaping and cooling towers. Reliability matters — a hospital cannot stop.
Sampling plan and inlet characterisation → process design (PFD, P&ID, sizing, BOQ) → supply, erection and commissioning → biological stabilisation → handover with O&M manual and training → AMC if you want us to stay. We also audit and upgrade plants built by others.
On beds (400–500 L/bed/day), OPD footfall, staff and canteen, plus a growth margin — we calculate from your occupancy plan, not a rule of thumb alone.
MBR gives the clearest water and smallest footprint, ideal for reuse and basement installations; MBBR is simpler and cheaper to run where space allows. We recommend after seeing site and reuse targets.
Conventional biology removes part of them; MBR and activated carbon improve removal; advanced oxidation is added only where a specific requirement exists.
Flow, inlet analysis and required outlet — we reply with a scheme and budget range within one working day.
