Blondal equipment is designed for the pretreatment or filtration stage of an industrial water-treatment system. The green cylindrical tank houses layers of filtration media — often sand, gravel and activated carbon, Which remove suspended solids, turbidity, organic contaminants, and sometimes iron or manganese from raw water. After passing through the media bed, the water is much cleaner before entering subsequent treatment steps.

Key features typically include:

• A robust, pressure-rated vessel (Stainless Steel or FRP) to withstand industrial process flows.
• Inlet and outlet piping, valves, and sometimes an automated backwash system to flush the media bed and restore performance.
• Internal media layers configured to optimise sediment capture, depth filtration, and in some cases activated-carbon adsorption.
• Modular layout so it can be part of a larger system (skid mount or series banks) for high flows.
• Suitable for industries requiring water treatment of large volumes, for example manufacturing, process plants, or municipal feed water pretreatment.
