DOCKING STATION
Open circut station with dual deputation string
The DS can be used as a standalone unit or together with the other AQUALIFE closed circuit applications.
As a standalone unit the docking station can be used in places where there is no risk of wastewater contamination, meaning that only shellfish and fish native to the area are kept in the facility – the stand alone docking station is not capable of purifying and safely disposing of hazardous waste water.
The docking stations have two piping strings that each connects to 20 tanks or 20 tubs. Through the strings the water is circulated through the power unit for chilling and purification.
The open circuit station can be used as a local collection point for part loading an ocean freight container The station can hold 40 tanks (one container) or 20 tanks and twenty 1000 litres tubs (60 m3 capacity)
The station is capable of maintaining a temperature of 2 celcius degrees and to cool down 20 celcius degrees warm water within a maximum time of 4 hours. The unit is mounted on a pallet for easy handling and cleaning.’
NB: if you are planning to keep shellfish or fish in the docking station not native to the local area, you will have to add a Closed circuit Purifier or even a Closed-Circuit- Purifier w’ Membranes . This gives you the opportunity to dispose wastewaters without running the risk of polluting your local seawaters with invasive diseases and spices.
NB: if you do not have access to class A seawater, you will either need to add a Fresh-Water-Salitation Unit or a Closed-Circuit- Purifier w’ Membranes.
Specifikation:
Filtration:
-Pre filter for large items; shells, small rocks etc..
-Micro filter with automatic back flush: clean organisms down to a size of approximately 0.01 microns.
-Ultraviolet filter: dose 254 NM (Nanometre), wavelength (optimal wavelength of 264 NM).
Chiller:
-Cooler will keep the water in a recircular environment at 2 degrees Celsius.
-The maximum flow of a DS is 20 M3 per hour. This will make it capable of running 2 strings simultaneously. This means that the water exchange in the units (Aqualife tanks or tubs) will be 500 litres per hour. A daily water flow per unit of 12 m3 litres.
Wastage:
-The DS has a brine mixing unit to create salt water. This unit ensures that water spillages is not an issue, and ensures enough water to get the water flow running.
Power supply:
-The DS requires 3 faced 400 volt power supply at 50-60 Hz With a 32 Amp fuse.
Surveillance:
The system is equipped with a digital surveillance system that through a digital display will inform the user of the following:
-salt content
-Oxygen saturation
-PH
-Ammonia
-Flow
- Temperature
The surveillance system shares the PLC interface with the general interface to the system. The system is further equipped with an 8 channel alarm that will alert the operator if any of the measured values falls outside the pre set tolerances.
