Water filtration units are essential components in water treatment systems, used to remove impurities, suspended particles, and contaminants from water. Multi-grade filters (MGF) and activated carbon filters (ACF) are commonly used in these units, and they can be manufactured in different materials, including fiber-reinforced plastic (FRP), mild steel (MS), and stainless steel (SS).

Multi-grade filters (MGF) use multiple layers of filter media, typically sand, gravel, and anthracite, to remove impurities from water. The MGF can remove a wide range of contaminants and particles, and it is commonly used in pre-treatment for reverse osmosis systems, boiler feed water treatment, and swimming pool filtration. MGF units can be manufactured in FRP, MS, and SS, depending on the application and desired operating conditions.

Activated carbon filters (ACF) use activated carbon to remove impurities and contaminants from water. The activated carbon has a large surface area and can adsorb a wide range of pollutants, including organic compounds and chemicals. ACF units are commonly used in drinking water treatment, wastewater treatment, and industrial processes. ACF units can also be manufactured in FRP, MS, and SS, depending on the application and desired operating conditions.

Fiber-reinforced plastic (FRP) is a popular material used for water filtration units due to its excellent corrosion resistance, durability, and low maintenance requirements. FRP units are lightweight, easy to install, and can withstand harsh environmental conditions. MS and SS are also commonly used for water filtration units, depending on the application and desired operating conditions.

In summary, water filtration units are essential components in water treatment systems, and multi-grade filters (MGF) and activated carbon filters (ACF) are commonly used in these units. They can be manufactured in different materials, including FRP, MS, and SS, depending on the application and desired operating conditions. The selection of the appropriate material for water filtration units depends on factors such as durability, corrosion resistance, and maintenance requirements.
