Frequently Asked Questions on Water Treatment

Common questions regarding turnkey plant sizing, membrane cleaning, STP/ETP revamping, and Pollution Control Board compliance.

Direct Answer: We provide turnkey commissioning, revamping, and AMC for Reverse Osmosis (RO) Plants, Sewage Treatment Plants (STP), Effluent Treatment Plants (ETP), Water Treatment Plants (WTP), Zero Liquid Discharge (ZLD) Systems, Mineral Water Plants, and Water Softeners.

Whether you are setting up a new industrial facility or need scheduled maintenance and media replacement for an existing plant, our certified engineering team handles everything from raw water analysis to commissioning and regulatory compliance.

Direct Answer: CIP chemical cleaning is recommended whenever normalized permeate flow drops by 10-15%, feed pressure increases by 15%, or salt passage increases by 10-15% (typically every 3 to 6 months depending on feedwater TDS and SDI).

Our industrial RO service includes high-pressure chemical circulation using specialized acidic and alkaline descaling formulations to dissolve mineral scale, biofouling, and colloidal silicates without damaging the thin-film composite polyamide membrane structure.

Direct Answer: Yes. We specialize in upgrading older conventional activated sludge systems to MBBR (Moving Bed Biofilm Reactor) or MBR (Membrane Bioreactor) configurations, increasing hydraulic capacity by up to 50% within existing civil tank footprints.

Our engineers replace depleted biological carriers, overhaul aeration diffusers and blowers, and retrofit tertiary filtration systems with activated carbon and multi-media sand filters to bring discharge quality up to current TNPCB standards.

Direct Answer: Yes. Repuls Internationals manufactures and supplies complete laboratory testing instruments (digital pH meters, TDS/conductivity meters, turbidity meters, spectrophotometers) as well as certified laboratory glassware and testing reagents.

Our Lab Instrument Service includes routine precision calibration, electrode replacements, and calibration buffer solutions to keep your in-house quality control facility running accurately.

Direct Answer: Through biological culture monitoring, optimized coagulant-flocculant chemical dosing, multi-barrier tertiary filtration (activated carbon + sand), and periodic third-party NABL-certified testing.

Under our Annual Maintenance Contracts (AMC), we monitor BOD (Biological Oxygen Demand), COD (Chemical Oxygen Demand), Total Suspended Solids (TSS), and Ammoniacal Nitrogen parameters on a weekly and monthly schedule to ensure complete compliance with local environmental regulations.
