Water & Wastewater HiOx™ Ultra-Fine Bubble Panel Aeration System An Advanced Energy Efficient System Which Can Increase Transfer Efficiency by up to 30% The HiOx™ Advantage Applications The most energy intensive operation in any activated sludge plant is • High-rate aeration processes. associated with the requirements for mixing and aeration. The HiOx™ • Activated sludge. ultra-fine bubble diffuser reduces that energy requirement by increasing • Membrane bioreactor. the transfer efficiency by 20% to 30%. This is achieved by producing smaller bubbles and having high floor coverage, giving a low flux rate. This higher transfer efficiency translates to reduced air demand and thereby to reduced operating costs. Advantages The Diffuser • Energy savings. • High SOTE (Standard Oxygen Transfer Efficiency). The diffuser membrane is made of high-strength polyurethane supported on two-ply polyurethane with a nylon reinforcement body, separated into several strips by radio frequency (RF) welds. This is supported on • Low flux. • High floor coverage. • Very small bubbles. • Independent testing (ASCE). • Lightweight units. • Minimal piping. • Long membrane life. • Easy membrane replacement. a stainless steel frame with 6 anchors and threaded bolts for precise levelling. Each diffuser measures 3.6 m by 1.2 m, and weighs 32 kg. How It Works The HiOx™ produces 1 mm diameter ultra-fine bubbles which decreases the electrical consumption of the system. 5-10 mm bubbles are found in many coarse bubble aeration systems, while 2-3 mm bubbles are found in many fine bubble aeration systems. Each panel diffuser covers a large area, roughly equivalent to 4.3 square meters. These specially developed, lightweight panels are covered in high strength perforated polyurethane. The slick surface of the polyethylene membrane is self-cleansing. This cleaning effect is further facilitated by the flexing caused by air flowing through the diffuser panels.

Wa te r & Wast ewate r HiOx™ Installation & Maintenance HiOx™ offers a lower installation cost as each diffuser High covers a large area and has an aeration area equivalent to one hundred standard 22 cm discs. As the number of required to feed them. This design feature also significantly reduces installation costs. Each diffuser has it own feed line and isolation valve, which allows the operator to fine tune the air distribution to best match a plant’s changing needs SOTE (%) diffusers is greatly reduced, so is the amount of pipe work and isolate one or two panels if required. Simply flexing...
