Chlorine, colour, odour, and dissolved organic compounds in feed water damage RO membranes, reduce product water quality, and create compliance failures in treated effluent. Standard filtration alone cannot address these dissolved chemical contaminants.
Activated Carbon Filters (ACF) solve this at the source. Using a high-surface-area carbon media bed, they adsorb chlorine, chloramines, VOCs, pesticides, colour, and odour consistently and at industrial flow rates.
Trity Enviro is a trusted Activated Carbon Filter manufacturer and supplier in India, supplying FRP, MS, and SS-grade ACF systems to industries, commercial facilities, and water treatment plants across the country. Every system is custom-engineered to your flow rate, inlet water chemistry, and downstream process requirements.
An Activated Carbon Filter is a pressure vessel packed with high-grade activated carbon media — granular activated carbon (GAC), coal-based carbon, or coconut shell carbon — that removes dissolved chemical contaminants from water through a process called adsorption.
Unlike physical filtration that traps particles, adsorption works at the molecular level. Contaminants chemically bond to the vast internal surface area of the carbon particles and are removed from the water stream as it passes through the bed.
A single gram of activated carbon provides a surface area of 500 to 1500 m². This is what makes it exceptionally effective against a wide range of dissolved organic and chemical contaminants at low operating cost.
Protects RO Membranes: Chlorine and chloramines cause irreversible oxidative damage to polyamide RO membranes. An ACF installed before the RO system eliminates this risk entirely, extending membrane life and protecting your capital investment.
Improves Product Water Quality: For food processing, beverage, pharmaceutical, and packaged water industries, ACF removes taste, odour, and organic impurities that affect product quality and regulatory compliance.
Meets CPCB Discharge Standards: In Sewage Treatment Plants and Effluent Treatment Plants, the ACF serves as the final polishing stage to meet colour and COD discharge limits before outlet.
Reduces Chemical Dosing Cost: In chlorinated municipal supply lines, high chlorine residual forces higher antiscalant and reducing chemical dosing. An ACF normalises the chlorine level, reducing downstream chemical consumption.
Low Operating Cost: No chemical regeneration required. Backwashing with water restores flow capacity. Carbon media replacement is a straightforward, low-cost maintenance task every 2 to 4 years.

Fibreglass Reinforced Plastic vessels are the standard choice for most industrial and commercial ACF applications. FRP is lightweight, corrosion-resistant, and rated for pressures up to 4.5 kg/cm².
Ideal for: municipal feed water treatment, RO pretreatment, textile and dyeing units, commercial buildings, and standard industrial process water.
MS vessels with internal rubber lining (MS-RL) are specified for higher-pressure applications and large-capacity plants where FRP vessel dimensions become impractical.
Ideal for: large industrial plants, cooling tower makeup, municipal water treatment, and ETP polishing systems above 50 m³/hr capacity.
Stainless steel vessels are mandatory where material certification is required for product-contact water. SS 316 provides additional resistance against chloride-bearing and corrosive process water.
Ideal for: pharmaceutical manufacturing, food and beverage processing, packaged drinking water plants, and hygienic-grade industrial applications.
Feed water enters the ACF vessel from the top inlet and is distributed evenly across the carbon media bed through a top distributor system. As water travels downward through the bed, dissolved chlorine, chloramines, organic compounds, colour, and odour molecules adsorb onto the surface of the carbon granules.
Treated water exits from the underdrain system at the bottom of the vessel, consistently meeting the outlet quality targets for chlorine residual, colour, and organics.
The carbon bed has a finite adsorption capacity. As it loads with contaminants over time, contact time or Empty Bed Contact Time (EBCT) becomes the key design parameter. A correctly sized ACF maintains adequate contact time to deliver consistent outlet quality throughout the service cycle between media replacements.
| Contaminant | Removal Mechanism | Typical Removal Efficiency |
|---|---|---|
| Free Chlorine | Chemical reduction + adsorption | Greater than 99% |
| Chloramines | Adsorption (requires higher EBCT) | 80 to 95% |
| Colour (Hazen Units) | Adsorption of organic chromophores | Up to 90% |
| Taste and Odour | Adsorption of geosmin, MIB, H2S compounds | Greater than 95% |
| VOCs and Pesticides | Adsorption | 70 to 95% (compound dependent) |
| Phenol and Industrial Organics | Adsorption | 60 to 85% (higher EBCT required) |
| THMs (Trihalomethanes) | Adsorption | Greater than 85% |
Note: ACF does not remove dissolved salts, hardness, TDS, heavy metals, or microbiological contaminants. Downstream RO, softener, or disinfection systems address these parameters.
Our ACF systems arrive pre-assembled and factory-tested at our Ghaziabad manufacturing facility. Site installation is straightforward and typically completed within one to two days for standard systems.
Step 1 — Inlet Connection: The ACF is connected to the feed water line using the inlet port. A flow control valve or flow meter is installed upstream to maintain the design flow velocity through the carbon bed.
Step 2 — Initial Rinse: Before commissioning, the carbon bed is rinsed thoroughly to remove carbon fines. The flush water is discharged to drain until it runs clear.
Step 3 — Outlet Quality Verification: At commissioning, the outlet chlorine residual and colour are tested to confirm the system is performing to design. For RO pretreatment applications, outlet chlorine must be confirmed below 0.1 ppm before connecting to the RO membrane feed.
Step 4 — Service Mode: The system enters service and operates continuously at the design flow rate. For automatic systems, the PLC manages the service cycle and initiates backwash based on either a time trigger or a differential pressure (DP) trigger.
Step 5 — Backwash Cycle: Backwash is initiated when DP across the vessel exceeds the clean baseline by 0.5 to 0.8 kg/cm², or on a scheduled time basis for standard-turbidity feed water. Backwash restores flow capacity by removing accumulated particulate matter from the carbon bed. It does not regenerate the adsorption capacity — only media replacement achieves that.
Activated Carbon Filters are low-maintenance systems. A consistent backwash schedule and periodic outlet quality monitoring are the two most important maintenance activities.
| Task | Frequency / Trigger | Key Action |
|---|---|---|
| Backwash cycle | Every 24 to 72 hours or DP trigger | 10 to 15 minutes at 10 to 15 m/hr backwash velocity |
| Outlet chlorine check | Daily (for RO pretreatment) | Confirm below 0.1 ppm before RO membrane feed |
| Outlet colour and odour check | Weekly | Rising outlet colour or odour indicates media saturation |
| Bed height inspection | Annually | Top up media if bed height reduced by more than 10% |
| Carbon media replacement | Every 2 to 4 years | Replace when breakthrough chlorine or organics detected at outlet |
| PLC and valve calibration | Quarterly (automated systems) | Verify backwash flow rate and timing against design parameters |
Important: Backwashing an ACF removes accumulated particulate matter and restores flow capacity. It does not restore exhausted adsorption capacity. When outlet chlorine, colour, or organic levels begin to consistently rise above target values despite proper backwash, the carbon media has reached end of life and requires replacement.
Trity Enviro supplies carbon media replacement services across India under our Annual Maintenance Contract (AMC) programme.

Custom-Engineered Systems: We do not supply standard vessels with standard media. Every ACF system is sized based on your inlet chlorine level, flow rate, EBCT requirement, and downstream process. You get a system designed for your numbers, not an average figure.
Pan India and Overseas Installation: With a network of installation engineers and service personnel across India and project experience extending to international locations, we support your project wherever your plant is located.
Right Media for Your Application: Coconut shell GAC, coal-based GAC, and wood-based carbon have different adsorption properties. We select and supply the correct media grade for your specific contaminant profile — not the cheapest option available.
Complete Water Treatment Systems: ACF is rarely a standalone requirement. Our Multi-Grade Filter upstream removes suspended solids before the ACF, extending carbon media life. Our wastewater treatment systems integrate ACF as part of complete ETP, STP, and water recycling treatment trains. We supply the full system, not just the filter vessel.
After-Sales Support and AMC: We provide installation, commissioning, operator training, annual maintenance contracts, carbon media replacement services, and rapid breakdown support. Our clients are supported from order through to the end of the system's operational life.
