3. GENERAL
3.1 Description of the drum filter
The Bio-drum and/or the drum filter consists of a drum
sieve that is driven by an electro-motor. Additionally,
control electronics and a rinse pump are included.
The
drum filter serves to filter and discharge floating particles,
dirt particles and algal remains. Regarding the Bio-drum
there is an additional space, fitted with an air stone or air
disc, in which the organic filter material Helix can be
placed.
This drum filter is a product that may be applied only in
fresh water. The filter was designed for use in ponds.
The water to be filtered flows (due to gravity or pumping)
into the inlet openings of the drum. On the inside of the
drum, dirt will remain behind as a result of the mesh that
was fitted across the drum. As the cloth gets more
polluted, less water will flow through the drum. The water
level behind the drum will fall (in case of a gravity
installation) and a sensor present there, measuring the
water level, will subsequently activate the electronics. The
electronics will send a signal to the motor of the drum and
to the rinse pump. The drum will rotate, while the rinse
pump will, under high pressure, control the nozzles that
spray the mesh in the rotating drum clean. The waste
water is collected by a duct in the drum and will flow
outside, via the duct, for instance into the sewer. After the
set rinsing time has elapsed (14 seconds as standard), the
electronics will be deactivated again. The drum will stop
rotating and the pump will stop spraying water towards
the nozzles.
3.2 Warning
Only staff sufficiently knowledgeable about drum filters is
permitted to perform maintenance/activities on this
equipment. This staff must be familiar with the
international regulations for accident prevention.
Connection and settings must be in conformity with the
applicable electrical regulations.
