Maintenance

The Aquaconsult range of fine bubble diffusers and Hydrok’s unique approach to design
has reduced day to day operator maintenance requirements to an absolute minimum.

Routine maintenance is carried out automatically by sub routines programmed into the
control of the system. Diffuser membranes are cleaned daily by a deflation cycle that
flexes the membrane, effectively removing organic growth and deposits. The frequency
of this flexing cycle is increased if the pressure within the system exceeds pre-determined
set points. The number of flexing cycles is recorded and should this exceed recommended
levels an acetic acid dosing cycle may be initiated to clean more thoroughly.

Therefore depending on local conditions manual cleaning will be significantly reduced
or eliminated. In the unlikely event of manual cleaning being necessary, it is a simple
process using a high pressure hand lance.

Hydrok will also provide a planned maintenance programme to ensure optimum performance
at all times. This will be carried out by our own locally based maintenance engineers.

The manual cleaning of tanks and diffusers should be avoided where possible. By using
extractable sample points that provide a safe means of examining the conditions at
the bottom of the tank without draining down, the need for man entry can be
significantly reduced.
