GM FILT Multi-Grade Sand Filter is an advanced depth filtration system designed using a precisely engineered blend of coarse and fine sand in fixed proportions. This unique media arrangement creates an optimized filter bed with ideal pore sizes, enabling the effective removal of both coarse and fine suspended particles from water.

GM FILT delivers significantly higher specific flow rates compared to conventional sand filters. Specific flow rates of 20–30 m³/m²/hr have been successfully achieved while treating water with 25–30 ppm suspended solids, consistently producing a filtrate quality of less than 5 ppm.

The filter vessel is available in FRP and MSRL construction, selected based on application requirements, system capacity, and site conditions. Designed for durability, high performance, and ease of installation, GM FILT systems are robust, reliable, and maintenance-friendly.

Applications of GM FILT include:

• Potable water filtration
• Cooling tower water treatment
• Effluent treatment plants (ETP)
• Drinking water systems
  
  

GM FILT ensures high filtration efficiency, superior water clarity, long media life, and dependable performance across a wide range of industrial and utility applications.
