Filtre et biofiltre pour aquaponie et aquaculture

Get Superior Biofiltration

The self-automated backwash process requires no moving parts or electronics.

Under development for several years, the patented PolyGeyser® technology is capable of handling ammonia loads 50% – 100% higher than standard bead filters at a fraction of the water loss and head loss.

The innovative backwash process prevents caking and clogging – keeping your day-to-day operations moving along smoothly. The backwash is gentle, keeping the biofilm intact while allowing the system to operate for long periods of time with no maintenance.

PolyGeyser Benefits:

  • Automatic backwashing – these filters clean themselves
  • PolyGeyser has been tested and proven for over 20 years
  • Optional Airlift offers additional energy savings
  • Superior biological filtration with 1.5x Bubble Beads
  • The biofilm remains protected from frequent backwash cycles
  • Simple design has no moving parts to break
  • Water loss is reduced – only concentrated sludge is removed

About backwash

Your patented PolyGeyser® filter technology employs a static bed of beads to capture suspended solids and provide substrate for development of a biofilm to remove targeted dissolved pollutants (organics, ammonia). After time, the accumulation of solids in the bed begins to reduce t the flow passed through the unit. Each application has its optimum interval for backwashing. In some cases, an extended backwash interval produces optimum performance and in others, and extremely short backwash interval is best. In broad terms, short backwash intervals (<6 hours) are associated with heavy loads. Best performance for lightly loaded applications is usually associated with extended backwash intervals (>12 hours).

Lightly loaded applications with a focus on water clarity (reduced turbidity) are generally associated with extended backwash intervals, perhaps, twice a week. In lightly loaded application seeking high water clarity, start with a backwash interval of once a day. Increase the backwash frequency (turn up the air) if the flow through the filter declines significantly as this is a sign solids are not being backwashed enough for your application. In recirculating applications, the backwash tuning success is reflected in the TAN and Nitrite concentration. It is not uncommon to see the TAN concentration reduced by 50% with a small change in backwash frequency.
