Filtration rateRecommended: 25 m/h

m/h

A planning rate for sand or glass media filters.

Filter assumptionsSand / glass media

This calculator uses a media-filter loading rate. Cartridge and D.E. filters require model-specific flow and surface-area data, so confirm those options against the manufacturer's product information.

For irregular pools, enter the customer's estimated water surface and average depth. All results are preliminary equipment-sizing references.

Plan view

Indicative geometry for equipment-sizing reference only—not an engineering or construction drawing.

Transparent by design

From dimensions to a practical starting point.

The calculator keeps its inputs clear, helping customers describe their pool before asking Bilanda for suitable equipment guidance.
