Manufacturer and Supplier of Industrial Sand Filter in Chennai
Greenly is Chennai’s trusted source for robust industrial sand filters that safeguard water-dependent processes in factories, food plants, chemical works, and more. Whether you need high-pressure throughput for a cooling-tower loop or an energy-efficient low-pressure solution that pairs with reverse-osmosis (RO) units, every filter we build delivers crystal-clear water, lower operating costs, and years of trouble-free service.
Why Choose Greenly Sand Filters?
Engineered for high & low pressure
Vessels are FEA-validated and hydro-tested to 1.5 × working pressure, so you get stable flow rates, no media channeling, and consistent turbidity removal even when pressure swings.
Seamless RO pre-filtration
Placed upstream of an RO system, a Greenly sand filter intercepts silt, rust, and organic debris ≥ 20 µm, cutting chemical cleaning cycles by up to 40 % and extending membrane life by 18–24 months.
Durable, corrosion-resistant build
Tanks are fabricated from IS 2062 carbon steel and epoxy-lined at 250 µm while internals use SS 304/316 or food-grade PVC—zero pinhole corrosion even in coastal Chennai’s saline atmosphere
Key Features
1
Effective particle & sediment removal – Multi-layer silica sand (0.4–0.8 mm) over graded gravel captures suspended solids, oxidised iron, and algae down to 20 µm. Typical outlet turbidity < 1 NTU.
2
Optional carbon-sand dual media – A combined coconut-shell activated-carbon layer polishes colour, odour, and residual chlorine in a single skid.
2
3
Extractor-pump compatibility – For flows above 120 m³/h we integrate inline extractor pumps and DP gauges so backwash cycles trigger automatically.
4
Easy maintenance & low downtime – Tool-free manways, snap-fit hub-lateral distributors, and a four-step backwash programme mean one technician can restore media in under 20 minutes.
Applications Across Industries
Manufacturing & cooling towers
Keep heat-exchanger tubes free from scaling particulates, protect pumps, and maintain stable ΔT in recirculating loops.
Food & beverage compliance
Meet FSSAI and IS 4251 hygiene norms by pre-treating process water for bottle rinsing, CIP, and steam generation.
Chemical & pharmaceutical purity
Prevent catalyst poisoning and particulate contamination in batch reactors, API wash-downs, and purified-water units.
Technical Specifications
Filtration media & grain size – High-grade silica sand (0.4–0.8 mm) and support gravel (2–4 mm). Dual-media option: 50 % activated carbon, 40 % sand, 10 % gravel.
Configurable operating pressure – 2–8 bar standard; custom vessels up to 12 bar. All units hydro-tested to 1.5 × design pressure.
Custom flow rates & footprint – Single units 5–150 m³/h; duplex or parallel skids up to 600 m³/h. Vertical or horizontal orientations for tight utility rooms.
Benefits for Your Plant
Enhanced water quality – Achieve < 1 NTU turbidity, SDI < 3, and stable pH, protecting downstream equipment from scaling and fouling.
Reduced OPEX & component life extension – Cleaner water extends seals, valves, and membrane life, while low head-loss design saves up to 12 % pumping energy.
Rapid ROI within 12 months* – Typical payback achieved through chemical savings, fewer RO cleanings, and minimized unplanned downtime.
Frequently Asked Questions
What flow rates can a single Greenly sand filter handle?
Standard vessels cover 5–150 m³/h. For larger demands we supply duplex or modular skids up to 600 m³/h.
How often should the filter media be replaced?
With proper backwashing (every 8–12 h of runtime) silica sand lasts 3–5 years; carbon media 18–24 months.
Can I retrofit a Greenly filter into my existing RO line?
Yes. We supply flanged or Victaulic connections, automate valve sequences, and match control-panel logic to your existing PLC.
Does the filter remove iron and manganese?
Yes—oxidised Fe/Mn particles > 20 µm are trapped. For dissolved forms, pair the sand filter with an aeration or catalytic-media stage.
