An activated carbon filter removes free chlorine, odour, colour and many organic compounds by adsorption onto highly porous carbon. In an RO plant it has a second, critical job: thin-film RO membranes are damaged by chlorine, and the ACF removes it before the water reaches them.
It is sized by flow and by contact time — the water must spend long enough in the carbon bed for adsorption to happen. The carbon is eventually exhausted and must be replaced; backwashing only removes trapped dirt.
Maintenance that matters
- Replace the carbon on schedule — exhausted carbon lets chlorine through to the membranes.
- Carbon beds can grow bacteria once chlorine is removed; downstream disinfection (UV) matters in potable systems.
- Put the ACF after the sand or multimedia filter, so it is not used up trapping dirt.
Installation, commissioning and service response
Commercial buyers are buying uptime, so the commercial terms matter as much as the equipment specification. Insist on these being written into the purchase order rather than discussed verbally.
- Site survey and feed-water analysis before the final quotation — never accept a specification produced without a water report.
- Defined commissioning scope: civil and electrical prerequisites, who supplies what, and a documented performance test at handover.
- Written service response times, with escalation, and clarity on whether spares are held locally.
- Operator training and a laminated SOP left on site, so routine flushing and cartridge changes do not depend on one person.
- Warranty terms stated separately for membranes, pumps, vessels and instrumentation, because they differ.
What a quotation includes
- Chlorine and organics review
- Vessel sizing by flow and empty-bed contact time
- Granular activated carbon media
- Backwash valve and controls
- Carbon replacement schedule
Why specify with us
Low total cost of ownership
High-rejection membranes, correctly sized pre-treatment and efficient pumps reduce power draw, consumable spend and reject volume. We quote five-year operating cost alongside capex, because that is the number that actually matters.
Heavy-duty SS-304 / SS-316 build
Corrosion-resistant stainless chassis and wetted parts engineered for continuous 24/7 duty, with SS-316 specified where chlorides or process chemistry demand it.
Rapid on-site servicing & AMC
Pan-India installation and service, with written response times and escalation in the AMC rather than verbal assurances — because plant downtime, not the repair, is your real cost.
Custom TDS tuning
Systems engineered against your actual water analysis — brackish groundwater, municipal supply or heavy borewell input, including high-TDS configurations for 3,000+ ppm feed.
Treatment architecture
- 1
Pre-treatment module
Multigrade sand and activated carbon filtration strips suspended solids, turbidity and chlorine that would otherwise oxidise the RO membrane.
- 2
Softening / antiscalant dosing
Protects membranes from calcium and magnesium scaling. On hard feed water this stage is not optional — it determines membrane life.
- 3
High-pressure RO module
Heavy-duty booster pumps drive feed water through industrial spiral-wound membranes at 12-18 bar in an array sized for your recovery target.
- 4
Post-treatment disinfection
UV disinfection and ozonation, with mineral dosing where potable taste and consistency matter.
- 5
Microprocessor / PLC controls
Auto start-stop on tank level, dry-run protection, high and low pressure cut-offs, and timed membrane flushing — with data logging on industrial plants.
