Enva Delivers Advanced UV Solution for Westmeath
Date: 04 February 2008
| Enva have announced the completion of its largest UV project to date for the supply, installation and commissioning of UV disinfection systems in part of the Westmeath water supply system. |
 |
| Providing drinking water disinfection for 4 water treatment plants, including an installation at the recently upgraded Athlone water treatment plant, these systems will ultimately treat approximately 10 million litres of drinking water per day. They will provide greater protection from disease causing bacteria that may be present in the raw water, including cryptosporidium and a range of other chlorine resistant pathogens. |
|
| With UV Technology, the disinfection process takes place as water flows through irradiation chambers. A photochemical effect is created using UV light, and vital processes are stopped within the micro-organism cells, therefore making the micro-organism harmless. The UV light inactivates microbes by penetrating cell membranes to disrupt DNA molecules and prevent cell replication. When a microbe cannot replicate, it is incapable of damaging humans. |
 |
| Commenting on this project, Finbarr Pyne, Technical Development Director at Enva noted; “UV is widely acknowledged as a critical component in the disinfection of a wide range of microbiological contaminants that can be found in drinking water. It has been successfully applied across the UK and United States for cryptosporidium inactivation, and research also shows that UV Technology is effective against all known micro-organisms, and provides a highly effective solution against bacteria, algae, moulds, yeasts, viruses, cysts and protozoa”. |
|
| He also noted; “Another key advantage of UV Technology is that it also destroys micro-organisms which are resistant to chlorine, while UV does not form disinfection by-products which can pose health risks”. |
 |
| Enva have now supplied in excess of 100 UV units of various sizes, with individual units ranging from low flow units to large flows of greater than 1,400m3 per hour. Units can be fully integrated with standard PLC or Scada controls, and are supplied in conjunction with ATG UV technology, who have over 25 years experience in the manufacture and application of UV Technology across a range of international clients, from large blue chip organisations and government controlled agencies. All units are third party bio-assay validated in accordance with the 2007 US EPA guidelines for UV Technology. |
|
| Greg Duggan, Senior Engineer, Water Services at Westmeath County Council advises; “‘Westmeath County Council provides quality drinking water for over 66,000 people throughout the county on a daily basis. The Council had to deal with an outbreak of cryptospiridiosis in 2002, which greatly impacted on the quality of life for one third of water consumers. In order to meet the demands of the new European Communities (Drinking Water) (No.2) Regulations 2007 and minimise the threat of a micro-biological contamination to its water sources, Westmeath County Council has introduced innovative technology and work procedures as a highly effective solution to a complex risk” |
|
| Highlighting the key supports services offered by Enva, Finbarr Pyne added; “As well as supplying and installing UV Technology, Enva also offer the reassurance of a full and immediate after-sales service backup. We offer full maintenance contracts by fully trained service engineers. We also provide a 24 hour callout service as part of our maintenance contract, while our facility in Cork carries a full range of back-up equipment”. |
