Basic Filter Types
Pump
Fed Vortex Filter System.
A vortex is
used to settle out waste products and heavier solids. Water is injected
along one side to induce a whirlpool effect called a vortex.
This encourages the heavier solids to sink and the cleaner water to rise to
the outlet and will reduce the workload of the filters by removing most of
the heavy solids and fish waste also reducing filter maintenance.
Pump fed
filters are installed above the level of the pond. Water is pumped up to the
filter and allowed to fall back to the pond

To work correctly, the first vortex in the system must be fed via the
inlet port (shown left).
Vortex units may be joined together in various configurations to
provide greater pre-filtration or to form part of larger multi-bay
filter systems. The example below left shows a dual vortex system to
provide extra settlement while the example below right shows a vortex
followed by extra vortex units used as filter bays |
