‘Development of a sustainable system for long-term breeding of aquatic organisms.Development of a sustainable system for long-term breeding of aquatic organisms.
In order to develop a technology for conducting experiments in space about long-term breeding of small aquatic animals, it is especially important to control the water quality parameters related to the microbial activity.

Contents

‘Development of a nitrification and denitrification batch processing technology. Removing of NH4+ and NO2 (toxic for fishes) by using denitrifying bacteria.
‘Development of a long-term dissolved oxygen monitoring/control technology. A long-term breeding in a closed environment requires an efficient monitoring of the air-pump performances, in term of oxygen consumption/supply and carbon dioxide accumulation/removing.
‘Check the effects of feeding and waste production on the eutrophication Since the wastes produced by the fishes may affect the water quality, it is important to monitor their composition and avoid their accumulation.
Approach: ‘ Support and monitor the activity of denitrifying bacteria
‘Evaluate the gas exchange efficiency via the contamination of the filter module.
‘Monitor the contents of proteins and amino-acids in the wastes, and verify the filter`s state.

‘Chemical instruments design and development
In the manufacturing of chemical devices and equipment, aspects such as the components’ structure, scale or volume, require numerous chemical and engineering calculations. Our company has experience in the managing of such type of tasks, as well as the performing of data validation.
Contents
‘ Pressure loss calculation
Study the specifications of fluid transfer equipment (such as pumps), and determine the appropriate pipes` diameter and length. Analysis of the pressure variation during the pumping stage and determination of the optimal pressure.
‘ Thermal calculation
Determination of heat balance, heater design, thermal insulation, heat capacity, flow heat transfer, convective heat transfer.
‘ Calculation of pressure resistance and earthquake resistance
Design of pressure-proof structure; study of devices` stability and earthquake resistance.
‘ Others
Calculation related to exhausts design (exhaust volume, exhaust port cross-sectional area), electron emitters design (lens diameter), radiation shielding, catalyst columns design (oxidation catalyst and reduction catalyst, etc.), humidification and dehumidification, emissions of special gases (volatile substances), and mass balance.
