Oxygen Diffusers & Aquaculture Aeration

The Dryden Aqua Air Diffuser is a semi-flexible, high-efficiency fine bubble air diffuser available in 9 different lengths, depending on the air through-put required . It provides oxygen transfer rates of up to 5kg/kw, 10m3/h of air and 1 kg of O2/h. Its semi-flexible construction with its own internal ballast will stay on the bottom of tank or pond without the need to be anchored to the floor. The Dryden Aqua Air Diffuser combines excellent performance with cost effectiveness for aeration, oxidation and biological treatment. Dryden Aqua Air Diffuser Key Features Semi-flexible, tubular construction Self weighted Available in 9 lengths from 0.3 – 3m. Air handling capacity from 1 – 10m3/hr Less than 0.2 Bar (3 psi) pressure differential Oxygen transfer efficiency up to 5 kg/kwhr Resistant to calcification Easy to clean and maintain Robust and long-lasting (typical lifespan is 5 – 10 yrs) Built in non-return valve Stainless steel and plastic construction Can be used with Air, N2, CO2 Oxygen Transfer Performance Surface aerators waste a huge amount of kinetic energy throwing the water into the air, transfer coefficient is 1 kg to 2 kg of oxygen per kW. Membrane diffusers are more efficient at 2 kg to 3 kg of oxygen per kW. The Dryden Aqua diffuser at over 5 kg is therefore the most efficient fine bubble diffuser available and is ideal for retrofit applications as a simple drop in product for tanks and ponds in Aquaculture and Waste Water Treatment.

These aquaculture-duty diffusers are among the most efficient diffusers available, allowing you to increase yield while controlling the cost of expensive gases. Made from premium materials and subject to rigorous testing, Micro Bubble Diffusers provide the kind of performance and reliability our reputation is built on. Size below depicts base dimensions. The original since 1988 These aquaculture-duty diffusers are among the most efficient diffusers available, allowing you to increase yield while controlling the cost of expensive gases. Made from premium materials and subject to rigorous testing, Micro Bubble Diffusers provide the kind of performance and reliability our reputation is built on. Point Four diffusers use a specially developed, ultra fine pore ceramic plate that produces a cloud of extremely fine bubbles of approximately 100–500 microns; far superior to airstones, porous hose or membrane type designs. The flat plate design ensures uniform bubbles across the entire surface and minimizes bubble coalescence to achieve an absorption rate in excess of 80%, depending on depth and flowrate. Bubbling Pressure is 25 to 35 psi. (1.7 to 2.4 bar). Applications for micro-bubble diffusers include pure gas applications (pure oxygen, carbon dioxide), high-density hauling, holding/growout tanks and emergency aeration.

Point Four Plastic Micro Bubble Diffusers (PMBD) are one of the most efficient diffusers available, allowing you to increase yield while controlling the cost of expensive gases. Made from premium materials and subject to rigorous testing, PMBDs provide the kind of performance and reliability our reputation is built on. Point Four diffusers use a specially developed, ultra fine pore ceramic plate that produces a cloud of extremely fine bubbles of approximately 100–500 microns; far superior to airstones, porous hose or membrane type designs. The flat plate design ensures uniform bubbles across the entire surface and minimizes bubble coalescence to achieve an absorption rate in excess of 80%, depending on depth and flowrate. Bubbling pressure is 25 to 35 psi (1.7 to 2.4 bar). • Robust construction—ceramic plates set in an injection moulded plastic base with solid brass connection fittings.• Flexible, modular design lets you easily add or subtract diffusers as your needs change. Applications for micro-bubble diffusers include pure gas applications (pure oxygen, carbon dioxide), high-density hauling, holding/grow out tanks and emergency aeration. Note: Diffusers are also known as airstones.
