Benthic Flume

General Specifications

• Flume is made of acrylic with the following dimensions : 50 cm deep, 50 cm wide, 732 cm long ;

• The flume rests on a seawater resistant fibreglass frame and contains sedimentation box and collimator to dampen cross-stream circulation;

• Water current within flume is driven by one variable speed electric drive 1 HP motor with speed controller, shaft and propeller. Water returned through a 12” pipe ;

• Water quality control module includes only chiller and titanium heat exchanger;

• Water temperature is maintained down to 10°C with air-cooled Chiller controlled by electronic thermostat (±1°C) ;

 

Anular flume General specifications

• Seawater resistant fibreglass table on which to rest an anular flume;

• Sturdy and levelled support for a motor and rod;

• Anular flume dimensions and design may vary depending on requierments;

Outer diameter 1,80M;
Inner diameter 1,40M;
Height 0,46cm;

• Flume comes with a fibreglas table with maximum ajustable height of 35 inches;

• System include ring, motors and control;

• Extreme care will be devoted to assure that all the equipment can be finely adjusted to level by users in client’s laboratory;
• Up to 4 evenly distributed plastic cores will be inserted on the floor of the flume.

 

8 channel flume General specifications

• Water velocity controlled independently in each flume; 
• Laminar flow over a 60 cm long section
  Range from 0.15 to 10 cm per sec;
• Precision 0.15 to 0.99 cm/sec: ±0.01 cm/sec ; 1 to 10 cm/sec : ±0.1 cm/sec
• Four Eco-type REBF (water recycling with biofiltration) are included, one common water recycling circuit for 2 flumes;
• Independent temperature control for each pair of flumes;
• Four Montrons are included in order to give that flexibility

 

• Eco-type REBF modules are for ecology-type studies (low fish density).
• This represents a maximum of 15 kg fish/m3 fed with a commercial dry diet at 2% body weight;
• This corresponds to approximately100 g of fish/channel. 
• The biofilter is pre-activated with your choice of active seawater or freshwater nitrifying bacteria.
• Working volume per flume (portion where flow is laminar) :  7.2 litres.
• Water temperature range is: 5-30°C at ambient temperature (20°C).  Water is chilled and warmed by two thermoelectric modules (Pelletier Effect) per set of two channels.
