Solvents, high COD, toxic and biorefractory compounds, antibiotics that inhibit biology, batch-wise discharges, pharma effluent needs segregation, stripping, sturdy biology and often ZLD. We have designed for API, intermediate and formulation plants.
API and intermediate plants generate concentrated mother liquors (COD 20,000–100,000 mg/L) alongside dilute wash water; solvents (methanol, toluene, DCM), high ammonia, sulphates and salts are common; formulation plants are milder but carry surfactants and actives. Norms include COD, BOD, TDS, ammoniacal nitrogen and, increasingly, antibiotic-residue expectations; many API units are under ZLD directions.
Sampling plan and inlet characterisation to process design (PFD, P&ID, sizing, BOQ) to supply, erection and commissioning to biological stabilisation to handover with O&M manual and training to AMC if you want us to stay. We also audit and upgrade plants built by others.
Toxic shock from un-segregated concentrates, solvents and antibiotics. Segregation, pre-treatment of concentrates and a buffer/equalisation stage protect the biomass; MBR with long sludge age tolerates variability better.
If your consent says so, yes. Otherwise a good reuse train (UF+RO) with reject to CETP is often the economical choice; we compare both on lifecycle cost.
Yes: stripping and recovery are designed upstream of biology; recovered solvent has value and the ETP is protected.
Flow, inlet analysis and required outlet; we reply with a scheme and budget range within one to two working days.
