02
Borewell Water
Reduce silt, sand and particulate matter before downstream treatment.
03
Commercial Buildings
Support common raw-water filtration for utility-water systems.
04
Industrial Utility Water
Improve inlet-water quality for process, cooling or equipment-support lines.
05
STP / ETP Tertiary Stage
Use as a polishing filtration stage where the treatment route requires it.
06
Irrigation & Agriculture
Help reduce particulate load before suitable irrigation distribution systems.
Recommended Treatment / Project Flow
Every site should be designed after understanding water quality, flow, end use, available space and operating conditions. A typical project flow may include the following stages:
01
Inlet Water Review
Assess turbidity, suspended solids, flow and any iron/oil/organic concerns.
02
Media & Vessel Selection
Select vessel material, media layers, flow loading and valve arrangement.
03
Filtration Cycle
Raw water passes through graded media to retain suspended particles.
04
Backwash Planning
Provide a planned backwash sequence and drain route to restore filtration performance.
Information Needed for Correct System Sizing
Sharing the following details helps the Ethix technical team recommend a practical configuration instead of selecting equipment only by name or capacity.
Raw-Water Inputs
- Turbidity / suspended solids
- Iron, algae or oil concerns
- Source and flow variation
Hydraulic Requirement
- Required flow in LPM / m³/hr
- Peak flow and operating hours
- Available inlet pressure
Plant Integration
- RO pre-treatment, WTP, STP/ETP or standalone use
- Existing pumps and pipe size
- Need for automation / multiport valve
Site Conditions
- Footprint and height
- Backwash water and drain line
- Power and control-panel needs
Key Project Benefits
- Reduces turbidity and suspended solids before downstream treatment.
- Helps protect RO membranes, softener resin and selected equipment from particulate fouling.
- Can be integrated into commercial, industrial and raw-water treatment trains.
- Flow-based sizing supports a stable filtration rate and practical backwash schedule.
- Available with suitable vessel, valve and control arrangement based on project duty.
How This Solution Differs From Other Water-Treatment Systems
| System / Stage | Main Role | Important Selection Point |
|---|---|---|
| Dual Media Filter | Reduces turbidity, silt and suspended solids. | Needs backwash water and a drain connection. |
| Iron Removal Filter | Targets iron/manganese-related water concerns. | Selected by iron chemistry, pH and water analysis. |
| Activated Carbon Filter | Targets chlorine, odour, colour and selected organics. | Does not replace DMF for high suspended-solid load. |
| RO Plant | Reduces TDS and dissolved solids. | Needs DMF/other pre-treatment to protect membranes. |
Project Support Across Pune & Maharashtra
Ethix Water Solutions supports commercial and industrial enquiries from Pune, PCMC, Mumbai Metropolitan Region, Nashik, Kolhapur, Satara, Sangli, Chhatrapati Sambhajinagar, Nagpur and other Maharashtra locations.

Frequently Asked Questions
What does a Dual Media Filter remove?
A DMF is typically used for suspended solids, silt, sediment and turbidity. Its actual performance depends on media, filtration rate and raw-water characteristics.
Is a DMF required before RO?
In many RO projects, a DMF or other suitable pre-filtration stage is used to reduce particulate loading. The final pre-treatment is selected from the water report.
Does a DMF reduce TDS?
No. A DMF does not reduce dissolved TDS. An RO plant is selected when TDS reduction is required.
How often does a DMF need backwashing?
Backwash frequency depends on inlet-water turbidity, operating hours, pressure drop and system design.
