Ultraviolet disinfection systems for the drinking water inspectorate
With atg UV systems treating in excess of 2500 m3/hr daily, Ultraviolet disinfection is no longer an ‘emerging` technology. A number of Water Treatment Works across the world are now investing heavily in Ultraviolet technology as the threat of chlorine resistant parasites, such as Cryptosporidium and Giardia, continue to pose a serious risk to water companies and their customers. To this end, in the UK, the DWI have issued their guidelines for UV operation and system selection to the UK water industry. A key feature of their guidance is UV system validation. Validation refers to a series of 3rd party testing to ensure the performance of an Ultraviolet system design under a range of operating environments.

Determination of chlorate, perchlorate, and chlorite ions in drinking water including bottled water
Introduction
Chlorination remains the most widespread way of disinfecting water in the world. Its flaws are: high toxicity of chlorine and other chlorinating reagents, also formation of various chlorine-containing compounds, including chlorite-, chlorate, and perchlorate anions. Maximum permitted levels (MPL) of these components are established in WHO Guidelines for drinking water and other regional and national regulations.

PremiumFiltration technology for Domestic wastewater treatment industry
AQQA® is used in domestic wastewater treatment to: act as barrier for bacteria and virus in membrane bio reactors (directly inserted into the mixed liquor). constitute the final filtration of the effluent of standard sewage treatment plants (tertiary treatment). supply hygienically safe water for reuse, e.g. irrigation of public places and crops. The treated water complies with the German Norm DIN 19650, EK2, reused water for the irrigation of crops for raw consumption. It also exceeds the standards according to the EU guidelines for bathing water according to EU guideline 2006/7/EG. eliminate micropollutants from wastewater, typically in combination with activated carbon.

Circuit Board Cleanliness Testing
Contamination of circuit boards can bring about severe degradation of insulation resistance and dielectric strength. Cleanliness of completed circuit boards is, therefore, of vital interest. For those companies who have established circuit board cleaning procedures, the MIL Spec P-28809 has been used as a guideline for control. Now a simple `on line` test for the relative measurement of ionic contamination has been developed. This fast and economical method for testing circuit board cleanliness uses a Myron L Company Ultrameter II™ 4P or 6P, a suitable container, and a mixture of Dl (deionized) water and alcohol.
