Lower Carbon Footprint With New Hydro Hiox High Performance Aeration System

THE HiOx Activated Sludge Aeration System, launched in the UK by Hydro International's Wastewater Division, achieves 20% improvement in sludge aeration performance, increasing treatment capacity and significantly reducing energy demands.

Hydro International has signed an exclusive licensing agreement with the US wastewater market leader Parkson to make the high efficiency HiOx system available for the first time in the UK and Ireland.

Suitable both for retrofitting and new installations, the HiOx has been developed to achieve much smaller bubble production and high floor area coverage, increasing transfer efficiency by 20% with a low oxygen flux rate, leading to reduced power demand.

"The most energy intensive operation in any activated sludge plant is associated with the requirements for mixing and aeration," says Chris Day, General Manager of Hydro's Wastewater Division. "HiOx cuts plant energy requirements dramatically and at the same time offers significantly increased capacity at a low installation cost."

HiOx's 1 mm diameter ultra-fine bubble production and high floor area coverage result in 20% or greater Standard Oxygen Transfer Efficiency (SOTE). It delivers aeration efficiency and flexibility in both high rate and conventional nitrifying activated sludge processes, and ensures Membrane Bio Reactor systems operate at optimum rates.

Lower installation costs are achieved because each HiOx diffuser covers a large area, equivalent to 100 conventional 22 cm disc diffusers. The specially-developed lightweight panels clad in high-strength perforated polyurethane (patent pending) enable a high floor area which reduces the need for associated pipework and ensures lower installation costs.

Maintenance requirements are reduced because the polyurethane membranes are self-cleansing, thanks to the slick membrane surface and the inherent flexing provided by the air flow. Isolation valves enable the user to fine tune each panel depending on demand and plant needs. The polyurethane membrane has a life of up to 12 years, and can be replaced easily.

The performance and durability of Hydro HiOx panels has been proven in use since the 1990s and has been tested and approved by the American Society of Civil Engineers.
