Sand Filter Manufacturer and Supplier in Chennai
Whether you manage a home, farm, factory, or RO plant, water clarity matters. Hard earned experience with the highly turbid sources common around Chennai has driven us to engineer sand filters that strip out mud, silt, and organic debris before they can foul pipelines or membranes. From compact domestic units to high pressure industrial vessels, we deliver proven performance backed by local after sales support.
Why choose our sand filter?
Multi layer quartz media captures particles down to 40 µm in a single pass.
Low friction under drain plates cut back wash water use by up to 30 %.
FRP or mild steel epoxy lined shells rated for 6 bar working pressure.
Built in Chennai, spares stocked locally, and service calls within 24 hours.
Product & Application
Residential sand filters
Protect RO systems and washing machines from grit. A typical 10 × 54 in (25 L) unit treats 2 m³ h, slashing cartridge filter changes and extending RO membrane life by 40 %.
Sand filters for agriculture & irrigation
Layered sand and gravel beds block suspended solids that clog drippers. Models up to 20 m³ h keep subsurface drip lines flowing, even with open well or canal feeds.
Ro pre filters for commercial plants
Every litre that reaches an RO membrane first passes through our rapid sand vessels, lowering SDI from >5 to ≤1.5 and lifting permeate output while cutting membrane cleaning chemical cost.
High pressure industrial sand filters
Pharmaceutical, food processing, and textile clients rely on 1 000 mm dia. filters that handle 15 m³ h at 5 bar, removing fine fibres and colloids before EDI or softener trains.
how a sand filter works
✔
Influent water enters above the media, distributing evenly across the bed.
Solids are trapped as water percolates through successive layers of coarse gravel, fine silica, and garnet.
✔
✔
Filtered water is collected by a hub and laterals under drain, then sent to storage or downstream treatment.
Frequently Asked Questions
How often should I back wash?
When the pressure drop rises by 0.7 kg cm ² or at least once every 7 days for surface water sources.
What is the media life?
Silica sand typically lasts 3–5 years with proper back wash; replace when it rounds or cakes.
Can the same filter handle RO feed pressures?
Yes—our industrial series is hydro tested to 10 bar and operates safely at 6 bar.
Which contaminants are removed?
Mud, rust, silt, micro flocs, algae, and any particle larger than about 40 µm.
How do I know it’s clogged?
Monitor the inlet/outlet pressure gauge pair—an increasing differential means it’s time to back wash.
