In recent years, with the sharp increase in human energy consumption and the concentration of carbon dioxide gas in the atmosphere, the global climate has become increasingly hot. As a major energy consumer, the low-carbon reform for traditional aquariums is imperative. The old generation of oceanariums relied on high-energy mechanical filtration systems, which resulted in huge energy consumption costs (accounting for more than half of the total annual operating costs of the oceanariums). We replaced the old generation’s high-energy mechanical filtration technology with low-energy ecological technology, which will significantly reduce the huge energy consumption of animal and plant exhibition halls such as oceanariums by more than 5 times and reduce maintenance and operation costs by more than 2 times.
