Water Filtration
Water often contains suspended solids, turbidity, silt, sand, iron and other particles that can damage equipment, reduce process efficiency and affect product quality. Inovar’s Water Filtration systems provide robust, multi-stage solutions that ensure consistent removal of physical impurities across a wide range of applications in India. We don’t offer one-size-fits-all filters. Every Inovar system is tailored based on raw water characteristics, flow rate, and downstream requirements.
What do we do differently?
- Conduct turbidity, silt density index (SDI), and particle size analysis
- Design multi-layer media beds with graded gravel, sand, anthracite, and garnet
- Customize filters (Pressure Sand Filter, Iron Removal Filter, Dual Media Filter, etc.) as per industry needs
- Offer both manual and fully automated systems with backwash control
- Provide modular skids with corrosion-resistant fabrication

Having Trouble with Water Filtration System?
We assess filter loading rates, media life, and fouling patterns to retrofit and restore performance.
Since 2019, Inovar has been leading the way in Water Filtration System in India
- We design with data, not assumptions
- We engineer for long-term performance, not just installation.
- We don’t cut corners to stay cheap.
- We prioritize total cost of ownership (TCO), not just CapEx.
- We care what happens after handover.
Inovar's Water Filtration System
Inovar’s water filtration systems combine multiple stages to remove physical, chemical, and organic impurities. Each component is selected based on water quality, application, and downstream requirements.
Water Filtration System Components
- Pressure Filter - Removes suspended solids and reduces turbidity using graded sand or multimedia.
- Dual Media Filter (DMF) / Multimedia Gravity Filter (MGF) - Combines layers of sand, gravel, and anthracite for high dirt-holding capacity and extended filtration cycles.
- Carbon Filter / Activated Carbon Filter - Removes chlorine, colour, odour, and organic contaminants from water.
- Iron Removal Filter - Eliminates dissolved iron and manganese, commonly found in groundwater sources.
- Water Softener - Exchanges calcium and magnesium ions with sodium, preventing scale formation in pipelines and equipment.
- Side Stream Filter - Used in cooling tower systems to continuously filter a portion of circulating water, improving overall water quality and reducing blowdown.
Frequently Asked Questions
What is a centralized water filtration system?
What are the common contaminants removed by a filtration system?
Our filtration systems effectively remove:
• Suspended Solids & Turbidity: Mud, sand, silt, and other visible particles.
• Colloidal Particles: Fine particles that cause cloudiness.
• Microbiological Contaminants: Protozoan cysts, bacteria, and some viruses (when using specific media like Anthracite or advanced membranes).
• Iron & Manganese: When oxidized, these form particles that can be filtered out.
How is filtration different from purification?
• Filtration primarily focuses on removing particulate matter—silt, sediment, rust, clay, and cysts (like Giardia and Cryptosporidium). It is a physical barrier process.
• Purification (e.g., Reverse Osmosis, Distillation) focuses on removing dissolved contaminants like salts, metals, and ions. Filtration is often a crucial pre-treatment step before purification.
What types of filtration systems do you offer?
We design and supply a range of technologies to suit different water qualities and requirements:
Multi-Media Gravity Filters (MMGF) / Pressure Sand Filters (PSF): Use layers of anthracite, sand, and garnet to remove a wide range of particle sizes. The workhorse for high-flow applications.
Activated Carbon Filters (ACF): Specialized for removing chlorine, organic compounds, pesticides, and
improving taste and odor.
Dual Media Filters (DMF): A two-layer system (typically anthracite and sand) for efficient solids removal
Cartridge & Bag Filtration: For polishing applications or protecting downstream equipment from fine particles.
Ultrafiltration (UF) Membranes: For absolute removal of particles, bacteria, and viruses down to 0.0 microns.
How do I choose the right filtration technology?
The selection depends on:
• Inlet Water Quality: The type and size of particles to be removed.
• Required Effluent Quality: The clarity needed for your process or compliance.
• Flow Rate: The volume of water to be treated per hour.
• System Footprint: Available space for installation.
• Capital & Operational Budget.
• Our engineers will conduct a water analysis and process review to recommend the optimal technology.
Where are your water filtration systems typically used?
Our systems are deployed across various sectors:
• Municipal Water Treatment: As a final polishing step after sedimentation to produce clear drinking water.
• Industrial Process Water: For cooling towers, boiler feed water pre-treatment, and product rinsing.
• Wastewater Treatment & Reuse: As a tertiary treatment step to remove residual suspended solids before disinfection or reverse osmosis.
• Pre-treatment for RO/UF: To protect delicate membranes from fouling and scaling, extending their lifespan.
What is the typical cost of a filtration system?
The cost is influenced by:
• Technology: Pressure Sand Filter vs. UF Membrane.
• System Capacity & Design Flow Rate.
• Materials of Construction (Mild Steel Rubber Lined, FRP, SS 304/316).
• Level of Automation.
• We provide cost-effective solutions tailored to your budget after a technical review.
My water has high iron content. Can a standard filter remove it?
A standard filter can only remove oxidized (ferric) iron, which is particulate. If your water contains dissolved (ferrous) iron, it must first be oxidized (typically by aeration or chemical dosing) to form a precipitate, which can then be effectively filtered out. We design complete iron removal systems that include both oxidation and filtration steps.
Do you offer Operation & Maintenance (O&M) support?
What is the regular maintenance required?
Maintenance is straightforward but critical:
• Media Filters: Regular automated backwashing. Occasional replacement of filter media every 5-7 years.
• Activated Carbon Filters: Backwashing and periodic carbon replacement (every 1-3 years) as it becomes exhausted.
• UF Systems: Regular backwashing and periodic Chemical Enhanced Backwash (CEB) or Clean-in-Place (CIP).
• Cartridge Filters: Replacement of cartridges when a differential pressure gauge indicates they are clogged.
