B-TYPE AUTO SAND is a sand filter which uses sand as the filter medium for depth filtration to capture heavy metals, and is the optimal solution for wastewater filtration. It reduces even traces of suspended heavy metal particles and other minute suspended solids from wastewater to regulation values or lower, and achieves a stable quality of treated water.

Features

• No need for complicated valve operation to switch between processes such as filtration and backwash, thanks to single touch valve operation system.
• Captures more suspended particles than conventional filter medium layers, thanks to unique shape and 3D arrangement of filter medium.
• Small specific gravity of filled filter medium means only a small amount of backwash water is required. Further large washing water savings possible if used with an air bubbling system.
• The total treatment efficiency of the entire system is further improved by using the filter as a component for the "Econoback System" (recovering and recycling system).
