Advanced biofiltration

An automated backwash process that requires no moving parts or electrical components.

Our Filter + Biofilter technology is capable of treating ammonia loads 50 to 100% higher than those of standard bead filters, with significantly lower water loss and pressure drop.

In addition, this innovative backwash process prevents clogging and fouling. Therefore, you can concentrate on the operation without having to worry about cleaning the filter.

This provides a thorough backwash that keeps the biofilm intact while allowing the system to operate for long periods of time without maintenance.

Benefits of the Aquaponics (AP) range of filters:

Automatic backwash – these filters clean themselves
Optional airlift circulation provides additional energy savings
Small footprint
Combined filtration and bio-filter (biological treatment)
Biofilm is preserved from frequent washing cycles
Simple layout with no moving parts that can deteriorate.
Reduced water losses – only concentrated sludge is evacuated.

Skids for quick and easy installation

With our skids, you can be sure to get a professionally assembled system. The skids are then delivered with all the basic filtration functions, plus UV disinfection as an option. In addition, the unit features an automatic backwash, using an easy-to-operate pneumatic backwash mechanism designed to save you time.

Mounted on a frame for indoor or outdoor use
Optional UV disinfection available
Optional additional on-line measurement probes (T°C, pH, O2, redox, conductivity, etc.), connected to the control cabinet
Alarm system by Wifi or SMS optional
Low power consumption
Skid can be adapted for use in seawater
Variable-speed centrifugal pumps with dry-running protection
Strainer basket upstream of the pump to collect large debris
Optional solenoid valve for mud evacuation

Design specifications

High performance backwash

This technology uses a static bed of beads to capture suspended solids and provide a substrate for biofilm development to effectively remove dissolved pollution (organic matter, ammonium). As time passes, the accumulation of material in the bead bed begins to reduce the flow rate through the unit. Each application has its own optimal backwash interval. In some cases, a prolonged backwash interval produces optimum performance (TSS) and in others, an extremely short backwash interval is preferable (nitrification). As a rule, short backwash intervals (<6 hours) are associated with large loads. Best performance for lightly loaded applications is generally associated with extended backwash intervals(>12 hours).

Low-load applications that focus on water purity (low turbidity) are usually associated with extended backwash intervals, perhaps twice a week. In lightly loaded applications that require clear water, start with a backwash interval of once a day. Increase the backwash frequency (increase the amount of air) if the flow through the filter decreases significantly, as this indicates that solids are not being removed sufficiently during backwashing. In recirculating systems, the success of the backwash adjustment is reflected in the concentration of ammonium (NH4) and nitrite. It is not uncommon to see the NH4 concentration reduced by 50% with a small change in backwash frequency.
