Diffused Aeration In Water Treatment

Oxygen is required by microorganisms bacteria residents in the water to break down the pollutants.

Diffused aeration in water treatment. Aerobic treatment and nutrient removal processes rely on the presence of oxygen for the removal of bod biological oxygen demand and the oxydation of nutrients. These tanks and the associated air diffusion equipment are the heart of the activated sludge process and typically are the single largest energy user associated with plant operations. Course and fine bubble diffused aeration products for all biological wastewater treatment needs. It is also effective in precipitating dissolved iron and manganese.

Several types of diffusers can be utilised to maintain the required oxygen concentrations and differ mainly on the pore size which define the size of the bubbles generated. Aeration adds valuable oxygen to a pond or lake particularly on the pond s bottom where muck and organic debris accumulates. An air diffuser or membrane diffuser is an aeration device typically in the shape of a disc tube or plate which is used to transfer air and with that oxygen into the sewage or industrial wastewater. Aeration water treatment is effective for management of dissolved gases such as radon carbon dioxide some taste and odor problems such as methane and hydrogen sulfide as well as volatile organic compounds like mtbe or industrial solvents.

In wastewater treatment the function of aeration is to introduce air into the water through the most effective and least costly methods that will increase oxygen transfer dissolved oxygen in the wastewater. Dualair fine bubble ceramic or membrane diffuser system 313 1 kb all documentation. It mixes wastewater with oxygen to allow aerobic bacteria to digest biosolid particles in the water. Diffused wastewater aeration systems aeration forms a vital part of the wastewater treatment process particularly the secondary treatment phase.

Activated sludge and biological treatment activated sludge aeration tanks are the largest applications for diffused aeration equipment. Diffusers use either rubber membranes or ceramic elements typically and produce either fine or coarse bubbles. A properly sized aerator works from the bottom up to ensure all areas of the pond are circulated and saturated with dissolved oxygen leaving you with a cleaner clearer and healthier pond. Aeration to maintain an aerobic condition.

Diffused aeration systems evoqua offers a complete line of coarse and fine bubble diffused aeration systems a complete selection of diffusers for mixing and or delivering oxygen to wastewater or other process water applications. Proven cost of ownership benefits.
