How it works:-
|
The Eazy tm is a stainless steel vessel containing a volume of static K1 media which is located within the centre chamber of the Nexus. Water enters the centre chamber and then enters the Eazy tm via slots in the lower half of the unit. This results in a downward flow causing many of the larger solids to settle out prior to entering the Eazy tm. The size of the slots will not allow large mechanical waste to enter the cylinder thus acting as a first stage mechanical filtration. The water then passes through the static K1 media utilizing up and side flow and this process causes the fine solids to become entrapped. The mechanically clean water then passes to the outside chamber of the Nexus where the Kaldnes moving bed tm is located for biological treatment prior to being returned to the pond. |
Maintenance
The Nexus Eazy tm is extremely easy and pleasurable to clean. The water pump is switched off and an air valve is operated which diverts air from the main Nexus air ring into the base of the Eazy tm. This causes the K1 media to be agitated and cleaned vigorously. As this happens the captured particles are flushed out into the central chamber of the Nexus, allowing you to see the amount of waste that has been filtered out. Once the K1 media has been agitated for a sufficient period, the water in the central chamber is flushed to waste using the purge valve provided at the base of the Nexus. Once clean, the air flow is re-directed back to the main air ring and the system started again. The whole process from start to finish can take less than two minutes.
