It is horizontal to promote sand filter comprehensive purifying for the high risk of cleaning and the deficiency of low efficiency；
Two, simple for assembly process, it is made of pipe fitting and connector；
Three, cleaning impurity is clear, and cleaning pipe is equipped with stomata, and assembling is placed on bottom of pond, is convenient to clean impurity, clears up from bottom to top
Thoroughly；
Four, input is few, and the application can be adjusted to water purification mode and cleaning by the inlet valve and purge valve for converting water inlet
Impurity mode, without newly-increased large-scale component material, Material Cost is suitable with conventional sand filter construction；
Five, sand filter water purification ability is not changed, the application without transformation, does not change into water, therefore not water inlet component
Water purification ability can be reduced.
The research and development of the application can be realized automatic cleaning, improves sand filter and clears up detergent power, promotes the aquatic products such as shellfish and educates
Seedling industry water quality safety.With actively pushing forward for China's mariculture industry upgrading synergy strategy, the research and development of the application have wide
Market prospects, for ensure breeding water body water quality safety have great importance.
