Here >> List > High-Precision Precision Plank Filter

Filtration plank is a key device in the filter technics and playing the dual role of bearing the weight of filtration medium and backwash water distribution(gas).By our Company further explorations in practice,a high-precision plank birthed,it can link with filtration pond closely,and not deformation,high bearing strength,and convenient construction.

The level of high-precision plate installation depends on three factors: smoothness and evenness of the plank surface,the evenness of the whole filtration pool,the accuracy position of the expansion bolts.
