Water treatment issues solved by Linde


From industrial wastewater to municipal water treatment, bulk oxygen (O2) and oxygenation systems from Linde can cost-effectively address a range of environmental control issues that often peak in summer months.

Oxygenation systems can help control BOD (biochemical oxygen demand) and associated odours, and pure oxygen can boost the efficiency of aeration water treatment systems – or completely replace them.

When an aeration system is pushed to capacity, plant odours can create community issues, and excess BOD can create compliance issues or result in fees or fines from water treatment authorities. Meat, poultry and other food operations are among those prone to such seasonal issues. At the same time, municipal water treatment plants may need to increase BOD treatment efficiency to respond to seasonal or other spikes from local point discharge.

Linde pure oxygen injection and O2 diffusion systems can boost dissolved oxygen levels much more efficiently than aeration systems, which require energy-intensive compressors. In addition, air is only about 21% oxygen.
