A: Water inlet
The pump is connected by means of a pressure hose to the water inlet.
B: Swirl-System
By means of gravity floating particles and contaminants settle down.
C: Biological cleaning
Microorganisms accumulate on the filter sponges´ pores. The blue and yellow
filter sponges differ in size and density. With different speeds, the water flows
through the different zones. As for the zones with a high flowing speed (blue fil-
ter), there settle mainly microorganisms that convert ammonia into nitrate. As for
the zones with a lower flowing speed, the growth of anaerobic microorganisms is
particularly supported which in turn oxidize nitrate to nitrogen.
D: Mechanical filter
Dirt particles are retained on the surface of the filter sponges before the water
flows towards the filter inside.
E: Cleaning of the pond water
When flowing out, the water is exposed to the ultraviolet radiation of the UVC
lamp thus killing germs, bacteria and algae. When flowing through the filter, the
water circulates from the outside to the inside.
F: Water outlet with flow indicator
On the outlet the cleaned water is led back into the pond.
G: Cleaning connection
Here, a hose can be connected in order to clean the filter. This is to remove the
accumulated dirt.
The waste water can be directly disposed of or used to water the flower bed.
H: Function switch
For selectively switch between „filtering“ and „clean filter“
I: Cleaning handle
The filter sponges can be cleaned manually by turning the cleaning handle.
