These substances will affect the effect of biological cultivation and the growth of microorganisms. The filter pool can effectively intercept and remove these suspended matter and impurities through its internal quartz sand and activated carbon to ensure that the water quality entering the biological cultivation system meets the requirements. The filter pool needs to be aerated when in use. Aeration can increase the oxygen concentration in the filter pool and promote the growth and reproduction of microorganisms. They can decompose organic matter and other pollutants in the water and convert them into harmless substances. Through aeration, sufficient oxygen can be provided to these microorganisms, thereby accelerating their metabolic activities and improving purification efficiency.
