Manufacturers, Exporters and Suppliers of Filter Media for Water & Wastewater Treatment – Sand, Gravel, Carbon & Multigrade Solutions in Bihar

Innova Corporate (India) supplies high-quality filter media for Bihar's water and wastewater treatment plants, including silica sand (0.4-0.8 mm, 0.8-1.2 mm, 1.2-2.0 mm), gravel support layers (2-20 mm), garnet sand (for multimedia filters – high density), anthracite (0.8-1.6 mm, 1.6-2.5 mm), activated carbon (coconut shell or coal-based, iodine number 900-1100 mg/g), manganese greensand (for iron and manganese removal), and calcite (for pH correction). For Bihar's municipal water treatment plants (supplying Ganges river water to cities like Patna, Muzaffarpur, Bhagalpur), we provide ISI/BIS certified filter sand with uniform coefficient (UC) <1.5 and effective size (ES) as specified. For sugar mill ETPs and CETPs, we supply activated carbon for color removal (melanoidins), COD reduction, and removal of trace organics – our coconut shell carbon has high hardness (>95%) and low ash content. For hotels and residential complexes in Bihar using groundwater with high iron (2-10 ppm) and manganese (0.5-2 ppm), our manganese greensand (MnOx coated, 1-2 mm) effectively removes iron and hydrogen sulfide without expensive aeration (greensand oxidizes and filters). For reverse osmosis (RO) pretreatment in Bihar's sugar mills (boiler feed), food processing, and pharma units, we supply multimedia filter media – typically a layer of garnet (specific gravity 4.0) at bottom, then sand (2.6), then anthracite (1.4) on top – to achieve a Silt Density Index (SDI) <3. All media are washed, dried, and graded per AWWA B100-16 or IS 8419 standards. We also provide complete filter vessel loading and replacement services for Bihar's industries – including removal of old media, inspection of underdrains, and reloading with new media. Pack sizes: 50kg bags, 1 MT jumbo bags. Technical support includes media depth calculation, backwash rate optimization, and SDI testing for RO feed. For Bihar's swimming pools (hotels in Patna, Bodh Gaya), we offer pool filter sand (0.45-0.55 mm) for high-rate sand filters. For dealkalizers and softeners (for boiler feed pretreatment in sugar mills), we supply ion exchange resins (cation and anion) as a separate product line. We also provide filter refurbishment contracts where we periodically inspect and replace media as needed.
