UNBSJ – TWO TIDE SYSTEMS

UNBSJ – TWO TIDE SYSTEMS

Projects dedicated to Research

UNBSJ – TWO TIDE SYSTEMS

Institution:

 University of New-Brunswick in Saint-John

Location:

 Saint-John, New-Brunswick, CANADA

Contact:

 Dr. Rémy Rochette

Habitat:

 Saltwater

Type of rearing unit:

 TWO TIDE SYSTEM RECIRCULATING UP TO 99,9% OF THE WATER
 

Unit description:

Four aquariums filtered, cooled and heated independently. Each aquarium have a tide simulation system;

At maximum flow rate (2 lpm), the 99.9% recirculation system requires no more than 0.12 litres of make-up water per hour.

Recycled effluent passes through a rapid action cartridge filter (16 microns) to remove fine solids and dissolved organics.

Degassing column (air intake included) for CO2 removing;

A thermoelectric module maintains a temperature range of 5-25ºC, provided that air temperature is at 15ºC;

The electronic digital temperature controller (Enviro-monitron) adjusts precisely (+0.1ºC) the water temperature.

One electronic controllers Enviro-monitron (Tide version) control the Tide and the Temperature for two aquariums;

The Tide simulation system consist:

  • 1 water level sensor;
  • 1 peristaltic pump (24VDC);
  • Each aquarium is divided in two tanks: one experimental tank (front tank) and one tank to accumulate the water (rear tank);
  • Capacity to regulate the water level from 3 to 56 cm;
  • Capacity to choose if the tide begin at low water or high water:
  • Capacity to choose duration between low and high water (300 to 420 min) and the number of consecutive flow.

Mandate:

Conception
Fabrication
On-site assembling, commissioning and training
