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 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
2
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.
Optional Carbon-sand Dual Media
A combined coconut-shell activated-carbon layer polishes colour, odour, and residual chlorine in a single skid.
Extractor-pump Compatibility
For flows above 120 m³/h we integrate inline extractor pumps and DP gauges so backwash cycles trigger automatically.
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 pumping energy.
Rapid ROI Within 12 Months*
Typical payback achieved through chemical savings, fewer RO cleanings, and minimized unplanned downtime.
Choose with confidence
Choosing the right filtration systems
- Identify the problem: turbidity, iron, smell, colour or chlorine.
- Match the filter size to flow rate (m³/hour) rather than tank size.
- Plan backwash water and a drain point near the filter.
- Use filtration ahead of RO or softeners to protect them.
- Agree a media replacement schedule at installation.

FAQs about Industrial Sand Filter
Still unsure? Ask us directly or call +91 95000 55565.
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.
Which filter do I need for borewell water?
Most borewell water needs a sand or multi-grade filter for suspended solids, and an iron removal filter if iron is present. A water test tells us which stages are needed.
What does an activated carbon filter remove?
Carbon filters reduce chlorine, odour, colour and many organic compounds. They are often used after a sand filter and before RO or softening.
How often should filter media be replaced?
Sand media lasts longer than carbon. Replacement depends on water quality and backwash practice; we share a schedule when the filter is installed.
What is backwashing?
Backwashing reverses the flow through the filter to lift and flush out trapped dirt. Regular backwashing keeps pressure drop low and media working.
Can you build filters for agriculture and industry?
Yes. We build sand filters for drip irrigation, industrial process water and RO pre-treatment in sizes to suit the flow.
Do you supply replacement media and cartridges?
Yes. Sand, carbon and other media, cartridges and membranes are available as spares.
