Dissolved Oxygen (DO) shortage can cause catastrophes in both natural waters and aerobic waste water treatment plants. In periods of high BOD and COD loading, or high ambient temperatures where biological activity and oxygen uptake rate are high, DO can fall to zero levels. At such times, higher aquatic life dies, odours can cause nuisance, and waste water discharges can exceed consent levels.

High purity oxygen brings immediate relief to oxygen shortfall. Air Products' rapid response oxygen supply via Oxy-Dep jet mixing equipment or Fine Bubble Diffusers can be installed on site quickly and effectively, often within 48h of request.
