UV Sterilisation for the treatment of bacteria.
Problem: Bacteria
Bacteria should be tested for by carrying out a laboratory analysis. Our advice is that if you have a private water supply you should have a UV steriliser installed. Even if an analysis shows that bacteria isn’t present in your water, you must bear in mind that the analysis was a point in time test and doesn’t show if bacteria is present at other times.
Solution. Install an Ultraviolet Water Disinfection System. A correctly sized UV steriliser will protect your private water supply from microbiological contamination. UV kills bacteria (E.coli, Coliforms etc.) mould, algae and virus contamination without adding chemicals – preserving the water’s natural taste and healthy minerals. All UV units should be installed with a pre-filter, often in the form of a cartridge filter. The pre-filter removes the larger particulate from the water, preventing the effect called “shadowing” whereby bacteria can pass through the water in the “shadow” of small debris.
The UV is normally the last piece of equipment in a treatment system to ensure it has the fully treated water giving the highest level of light transmission possible. The correct sizing of the UV is vital to ensure the correct dose and contact time. A UV lamp must be changed as a minimum every 12 months and the UV quartz sleeve checked periodically to maintain light transmission.
Springbore install the highest quality UV units. We can also incorporate a shut down solenoid valve into these systems. These solenoid valves close upon lamp or power failure. They are especially important for UV units that are remote from the house or systems that are gravity fed where water would continue to flow even during a power outage, resulting in potential harm to health. Warning systems in the form of audible and visual alarms and telemetry such as GSM auto dialler/text units are available to alert of fault conditions. Many existing UV units can be adapted to include this technology.
