Air disk bubble diffuser
Air disk bubble diffuser for transferring air and oxygen together with air to sewage or industrial wastewater. Microorganisms in water require oxygen to break down pollutants. The Air Disc Fine Bubble Diffuser series combines an effective design with low installation cost, reliability and high performance during intermittent and continuous aeration. Specially designed slits cut slits, slits and patterns for high oxygen transmission and long-term operation
