What is A Gravity-Fed Drum Filter, How Does It Works?

A gravity-fed drum filter is a type of mechanical filter used in koi ponds that utilizes gravity instead of a pump to move water through the system. Here's how it works:

Taking Advantage of Gravity:

The key to a gravity-fed system lies in its placement. The drum filter unit is positioned below the water level of the koi pond. This creates a natural downward flow of water due to gravity. make sure that the top of the filter is at lest 15cm above the pond water level.

Water Cycle Flow  Through the Koi Pond Filter:

1. Pond Inlet: Water enters the filter through a pipe connected to a drain point situated below the pond's water level. A valve on this line allows for controlling the flow rate.

2. Filter Drum: The incoming water enters the inner chamber of the drum filter unit. Here, it flows through a rotating cylindrical mesh screen.

3. Filtration Process: The fine mesh screen captures solid waste like fish waste, leaves, and algae, while allowing clean water to pass through.

4. Clean Water Exit: The filtered water exits the drum and flows out of the filter unit through a separate pipe with pump.

5. Waste Discharge:  The captured waste accumulates on the drum's surface. Most drum filters have a spray bar or nozzle that periodically sprays the mesh clean. This flushes the collected waste out of the filter unit to a drain or designated waste disposal area.

Things you need to consider:

Positioning:  Gravity reliance necessitates placing the filter unit lower than the pond. This may require digging a pit for the filter housing.

Water Level Maintenance:  The filter relies on a specific water level difference to function. Fluctuations in pond water level can affect performance.

Flow Rate:  The flow rate is determined by the difference in water levels between the pond and the filter.  This may not be suitable for all pond setups.
