Innova Corporate (India) supplies high-quality filter media for Delhi'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), 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 Delhi's municipal water treatment plants (treating Yamuna river water), we provide ISI/BIS certified filter sand with uniform coefficient (UC) <1.5. For textile ETPs and CETPs, we supply activated carbon for color removal, COD reduction, and removal of trace organics (dyes, auxiliaries). For pharmaceutical ETPs, we supply activated carbon for removal of APIs and solvents. For food processing and data centers using groundwater with high iron (2-10 ppm), our manganese greensand effectively removes iron and hydrogen sulfide. For reverse osmosis (RO) pretreatment in Delhi's ZLD plants (textile, pharma), we supply multimedia filter media – garnet + sand + anthracite – to achieve Silt Density Index (SDI) <3. All media are washed, dried, and graded per AWWA standards. We also provide complete filter vessel loading and replacement services. Pack sizes: 50kg bags, 1 MT jumbo bags. Technical support includes media depth calculation, backwash rate optimization, and SDI testing for RO feed.
