Sewerage Aeration

The efficiency of Leeaky Hose for aeration of fish ponds is equally relevant to the oxygenation of sewerage ponds. In most applications it will not only provide superior aeration for the same air flows, but will require less energy to achieve.

Also as it is not subject to corrosion, the longevity of LH is believed to be greatly superior to stainless steel pipes and membranes and most water lifting devices.

Installation

In most ponds the preferred installation method would consist of fastening Leeaky Hose in a spiral to a steel or plastic grid raised to a minimum of 20cm above the floor of the pond. A number of smaller grids would be preferred to the installation of a single large grid to allow redundancy and greater ease of handling.

Maintenance

While Leeaky Hose is not susceptible to blocking from the air flow, it can be prone to build-up of fungus on the outer wall. If this is not dealt with on a regular basis, the fungus will gradually grow into the wall cells.

This can be done by removing it from the water every 3 – 6 months and soaking in a chlorine solution, or passing a chlorine solution through it every three months.
