Water disinfection is a key factor in the process of providing quality water supply. ABCO water pump skids utilise ultraviolet and chemical treatments to produce a consistent quality of potable water supply.

Ultraviolet Treatment
Ultraviolet treatment has been used for over 70 years to eliminate disease-causing bacteria from industrial and commercial water supplies. Ultraviolet wastes no water, requires no chemicals and is inexpensive to maintain. A standard ultraviolet unit essentially comprises of a stainless steel casing and a mercury vapour lamp. The lamp is made with a clear quartz globe which transmits over 90% of ultraviolet energy to the surrounding water. The system incorporates a cleaning bracket which travels along the length of the lamp and prevents the buildup of biological organisms on the globe.

The ultraviolet systems used by ABCO require very little maintenance. General duties are limited to confirming the correct function of the UV unit’s operation. Each unit has built-in technology to self-check and notify via a liquid crystal display of any system errors.

Ultraviolet lights run at very high temperatures and rely on a constant supply of cool water to avoid damage to the system. By installing a temperature-controlled bypass system across all ultraviolet units, ABCO eliminates this risk and ensures that no further components are damaged by overheated water.

Chemical Treatment
Sterilisation is achieved by dosing the water with liquid chlorine. This serves to remove any contaminating biological organisms from the water prior to camp use. Chlorine levels should be continuously monitored to prevent over-dosing of chlorine, as this can lead to skin irritation. Typical chlorine levels for potable water should be limited to 0.3ppm.

Other form of chlorine sterilisation is by way of use of a Hypochlorination system utilising high grade salt, this removes the hazard of handling liquid chlorine and allows for long shelf life of the base material required to generate the chlorine.

Ozone Treatment Ozone treatment has been a continuously advancing technology over the past 40 years. As the technology is refined, it has become more viable for small to mid-scale water treatment facilities. The primary advantage of ozone treatment is that it has no residual effect on the product water; the only by-product of the oxidation and disinfection being oxygen. The other key advantage is that ozone generators can be installed on site, which eliminates the need for chemical supply and storage.

ABCO encourages the incorporation of ozone treatment into its future wastewater treatment plants as an alternative to traditional chemical treatments.
