Bio Reactor 10000

Bio Reactor 10000

This 3 chamber filter provides complete koi pond filtration in one unit.

The first chamber captures solids in the settling tank. The water moves cross flow through the settling tank and then through a baffle system of coarse Black Matala media. Very few solids pass through this mechanical filter stage. The V bottom is sloped for easy flush out of solid waste.

The second chamber acts as a mechanical / biological stage. Further small particles are removed and the bacteria whichs grows here will be primarily heterotrophic type. This means the bacteria will be digesting mostly dissolved organic matter derived from the solid waste in Chamber 1. This is an upflow chamber which allows for further settling of solids, thus preventing the medium coarse Green and Blue Matala from clogging. A 2 inch layer of open cell foam on top captures fine floc particles. and helps polish the water. The V bottom is sloped for easy flushing of waste particles and the organic floc which has been produced by the bacteria.

Chamber 3 is also an upflow chamber and acts as a pure biological filter. The water passes through the fine filtration of Blue Matala and Gray Matala. Another 2 inch layer of open cell foam is provided for fine polishing and floc capture. Since no appreciable solids reach this chamber, the bactteria growing here will be mostly autotrophic types. Thes types of bacteria function to digest the dissolve inorganic waste produced by the bacteria in chamber 2. This chamber rarely gets dirty and will become an extremely efficient biofiter.

Each chamber has a bottom drain valve for flushing waste. For in the ground, gravity fed installations, all chambers are drained to chamber #1 where an Eliminator 9 sludge pump (not included) can pump solid waste to the sewer.

This combination of all 3 chambers will provide you with complete koi pond filtration. Each chamber functions in a synergistic manner complementing each other as a true bio reactor. Your pond water quality will reach a level of stability where koi health is supported even under heavy populations and heavy feeding, as it should be. This type of filtration is not feasible or attainable in a pressurized type filter system.

Outside Dimensions:: 43" H x 44" D X 81" L

The system is complete and includes:

  • Heavy duty fiberglass construction 3 chamber tank.
  • 24 cubic feet of Matala media.
  • Drain valves, all inlet and outlet fittings.
  • Lid.
  • Each tank is custom built to your pond specifics regarding pipe size and locations. 4" pipe, 3" pipe, 2" pipe and 1.5" pipe sizes all available per order.
  • The system can be built as a gravity fed system or a pump fed system.

Bio Reactor 4000

Bio Reactor 4000

This two chamber tank can be configured as a bio/mechanical or a pure bio filter. It can also be conected to the Bio Reactor Settling Tank. Each tank has a slanted bottom with a drain. The Bio Reactor Filter can be installed above or a pond level depending on the set up. For in ground gravity installations we incorporate a well for an Eliminator 9 Sludge Pump (pump not inclued) in order to pump the waste to sewer or your garden. This makes cleaning very convenient. chamber 2 drains back into chamber 1 with the use of a standpipe included.

Outside Dimensions: 52"L x 28" W x 39.5" H

Contains approx 200 gallons.

The system is complete and includes:

  • Heavy duty fiberglass construction 2 chamber tank.
  • 12 cubic feet of Matala media.
  • Drain valves, all inlet and outlet fittings.
  • Lid.
  • Each tank is custom built to your pond specifics regarding pipe size and locations. 4" pipe, 3" pipe, 2" pipe and 1.5" pipe sizes all available per order.
  • The system can be built as a gravity fed system or a pump fed system.

Bio Reactor Settling Tank

Bio Reactor Settling Tank

A settling tank is installed ahead of your pump and biofilter. A settling tank will settle solid waste before it reaches the pump or biofilter. The water from the pond will flow via 3" to 4" bottom drains by gravity to the settling tank. In this way, solids are not ground up by the pump. The Bio-Reactor Settling Tank is positioned at the same elevation as the pond. The water level in the settling tank is the same as the water level in the pond. The top of the settling tank is positioned 2 inches above the pond water level. The bottom of the Bio-Reactor Settling Tank is ?? inches below the pond water level. This type of filter should be designed into the pond plan before you actually dig the pond. (Retrofitting a settling tank to an existing pond would require complete repiping in many cases and is not advisable.)

The Bio-Reactor Settling Tank is a two part system. The water enters the tank, upflows to the surface and gently rolls downward. This actually enhances settling of solids. Large solids will settle at this point. Smaller particles are baffled by a series of Black Matala mats. The smaller particles collect and conglomerate together, they become heavier and also settle. Very little solid debris passes through. The waste accumulates on the V bottom where a bottom drain or Eliminator 9 Sludge Pump (not included) will send it to the sewer.
