132 Commercial Pool Sand Filter Systems
How it Works
Soil is captured in the filter bed itself while solid particles lodge in the extremely small spaces and voids between the sand particles. Gelatinous, mucous-like substances and oils tend to cling to the grains of filter sand. Gravel/stone serves as a barrier which prevents the sand from washing through the underdrain into the pool during the filter cycle and also to distribute the flow of water uniformly to the underside of the sand bed during the backwash cycle.
All Mer-Made filter Systems are certified by NSF international and ANSI/NSF standard 50 for pool and spa applications.

Filter tanks shall be manufactured from fiberglass using heavy woven cloth as necessary for strength and have a minimum wall thickness of 0.3″. Filter tanks are designed for 50 psi working pressure with a safety factor of 4 to 1. Tanks are factory tested at 75 psi. The underdrain system shall be such that uniform collection of filtered water and distribution of backwash water is provided under the entire bed area. The underdrain pipe is PVC with slotted orifices. The total area of slots in the filter is equal to (4) times the area of the inlet pipe. The orifices in top laterals are equal to (7) times the area of the inlet pipe. The filter tank is provided with 12″ x 16″ fiberglass elliptical manway with gasketed yoke and bolt cover which is sealed by internal pressure. The filter shall be designed for a filter rate of up to 14 GPM per square foot of filter area and a backwash rate of 15 GPM per square foot of filter area.
