Easy filtration with a very compact automatic pneumatic backwash

AquaPonicSludge (APS) filter is an advanced version of our AquaPonic (AP) technology with the addition of many new features and increased purification performance.


  • Automatic compressed air backwash allowing the filter to operate for long periods without intervention. This saves time and labor
  • Lowest water loss filter in the industry, less than 5% compared to traditional filters
  • Large storage chamber to store the mud with minimal maintenance requirements
  • More solids removal and biofiltration in a single filter for crystal clear water
  • Low profile design allows water to be pumped by airlift, reducing energy costs
  • Simple, straightforward design with no moving parts or bracket replacement required, ensuring trouble-free operation.
  • Units arrive pre-filled with bead carriers that never need to be replaced

Additional options:

  • Automatic mud removal, making the filter virtually maintenance-free
  • Optional addition of UV disinfection for algae control even in hot environments.

The filter handles everything that passes through it

1H2O3 filters are suitable for ponds or tanks from 500L to 15 m3. In addition, they are used in :

  • Koi applications, aquaponics, for small fry
  • small scale applications of enlarging.

The following tables show the approximate sizes of ponds, tanks and aquaponics systems that the APS models will be able to filter.

Aquaponic Farms

These filters are perfect for aquaponics applications.

APS filters separate the solids from the water and store them in a large mud tank. Moreover, the latter allows a partial mineralization of the nutrients for the plants.

This nutrient-rich water can then be automatically discharged into the grow beds during the backwash cycle. The amount of water and frequency of discharge can be easily adjusted to maintain nitrate levels ideal for fruit production or growing green plants.

If you are looking for an integrated storage and filtration system for your projects, don’t hesitate!

Featured project

This APS filter is used in a small-scale domestic aquaculture project for tilapia farming.

He installed the filter in his greenhouse and insulated the tank with wooden boards to keep the water temperature constant.

In addition, for optimal energy savings, the APS filter is configured in airlift mode, without pumps or moving mechanical parts.

The mud is then collected in the chamber and automatically discharged into a nearby bucket, which facilitates maintenance.

AquaPonic Sludge : Configuration Standard

These unique filters backwash automatically several times a day.

  • During backwashing, the user does not need to stop the pump or close any valves.
  • In fact, the filter does not require a timer.
  • Injected air into the load chamber regulates the backwash cycle.
  • The filters clean and recycle the dirty water produced during backwashing every two to three hours.
  • Mud is only removed once or twice a week.

1) Filtering

  • The water first moves from the inlet to the log bed.
  • This bed provides a surface for water-purifying bacteria to filter and capture solids from the aquatic environment.
  • Slowly the air is then injected into the charging chamber, and concentrates at the top of the chamber.
  • As more air enters, the water level drops.
  • Lowering traps water in the settling zone, and solids from the last backwash concentrate in the sludge storage.
  • Finally, the air injection rate determines the time that elapses between two backwashes.

2) Start of backwashing

  • As the air made its way through the trigger to the bead bed, it was a bit of a challenge.
  • The resulting bubbles shake the beads, causing the solids and biofilm they contain to fall out.
  • As the air pressure in the load chamber decreases, the dirty water below the bead bed passes through the chute and carries the solids into the adjacent compartment.
  • No water flows out of the filter during the short 3 to 5 second backwash period;
  • However, contaminated backwash water is collected in the load chamber and the sewage tank.
  • The beads float in the drop zone where they continue to be swept up by the escaping bubbles.

3) While backwashing

  • Water flows down through the mixed bead bed and more solids are washed from the beds to settle to the bottom.
  • The downward flowing water sweeps the central compartment, rinsing away solids that have accumulated on the bottom of the filter and depositing them in the sludge basin.
  • The water level rises in the smaller rooms.

4) End of backwash

  • Water first rises in the mud chamber
  • This will cause the water to stop moving in the load chamber and the mud tank.
  • In addition, the trapped solids begin to settle when the filter chamber is refilled with water from the inlet.
  • Then, the beads float back to form the bead bed.
  • As soon as the water reaches the outlet, filtration will finally restart.

Periodic mud evacuation

  • At the end of the backwash, the beads rise to the top of the filter.
  • Most of the decanted solids are flushed to the mud chamber.
  • Filter will continue to backwash and filter several times a day.
  • Once the mud has collected, the user simply opens the mud valve to remove the concentrated mud from the filter.

The filter backwash frequency is usually set for a few hours, so that the filters are washed several times a day.

Mud will gather in the sedimentation chamber.

Every few days, or even once a week, the drain should be opened to remove the sludge.

Mud is a natural fertilizer that can be spread on the lawn or on a surrounding plant where it will degrade naturally.
