Aeration is a process in which stagnant or less oxygen content air is replaced by fresh air with sufficient oxygen content. It takes place due to atmospheric temperature, pressure and open structure. Hence artificial aeration becomes necessary. In this case, oxygen is dispersed by a pipe aeration system anchored at the bottom of the water. Aeration is used in nitrification/denitrification process in sewage treatment. It decreases the BOD (Biological Oxygen Demand) level in sewage. Unfortunately an escape of pure oxygen to the surface of water cannot always be avoidable. For this reason aeration plants situated near public waters such as lakes, ponds is dangerous to watercraft, people participating in water sports, anglers and even to people walking near water.

Mechanical aeration systems use surface or subsurface mechanical stirring mechanisms to create turbulence to mix air with the water. There are several types of aeration systems used for wastewater treatment applications that include mechanical aeration systems and diffused aeration systems. These systems effectively remove volatile organic compounds but are generally used for wastewater treatment systems. The diffused aeration system bubbles air through a contact chamber for aeration; the diffuser is usually located near the bottom of the chamber. The air introduced through the diffuser, usually under pressure, produces fine bubbles that inpart water-air mixing turbulence as they rise through the chamber. Diffused aeration systems are designed to serve either point-of-use or plant situations.

Aerial Boom Inspections range from an annual inspection of structural members, welds & bolted connections to complete inspection & testing during the manufacturing of new aerial devices.

Aerial cable systems primarily consist of tree wire conductors. The covered conductors of aerial cable systems are considered bare conductors for electrical insulation requirements. It is more suitable for long runs where there are few transformers and spurs lines. It is commonly strung together with LV cable on the same poles. The use of aerial cable systems to skid logs has not been widely introduced. It eliminates the need for multiple-duct underground construction and its numerous associated problems, such as; extreme high cost conflicts with other underground utilities, and extended vehicle traffic tie-ups during initial construction and future expansion. The advantages of an aerial cable system are (1) the cable cannot be accidentally dug up, and (2) most of the utility cables are on transmission lines, far off the ground and only accessible by trained professionals.
