설명

애플리케이션

• Inhibition of boric acid and sodium borate on the biological activity of microorganisms in an aerobic biofilter.: This research examines the effects of di-sodium tetraborate decahydrate on the biological activity of microorganisms in an aerobic biofilter. The study finds that di-sodium tetraborate decahydrate can inhibit microbial activity, which has significant implications for waste treatment and environmental management. This inhibition property can be utilized to control microbial populations in various industrial processes, enhancing the efficiency and effectiveness of biofiltration systems (Gunes, 2013).
