Shallow pond aeration

Shallow pond aeration

The typical aeration diffuser module in the pond aeration industry is a EPDM disc style diffuser adapted from the waste water treatment industry.  They are proven to be efficient and durable, with a long life.  However, if your pond is shallower than 4-5’, the disc style diffuser may not be your best option. The disc diffuser emits the bubbles in a circular pattern, which then spreads as they rise to cover an ever-larger area of the pond. However, if your pond or one area of your pond is less than 4-5’ in depth, the residence time of the bubbles is not ideal.  The large bubble plume rising from the disc does not have time to spread, due to the shallow water depth.  As a result, the mixing and aeration coverage area for that diffuser is reduced as the water becomes more shallow.
