For 60 years, Aquafine UV systems have been successfully serving the diverse Life Sciences industry. Aquafine UV systems are reliable, deliver consistent performance, and have become the brand of choice of WFI (Water-For-Injection) & USP (United States Pharmacopoeia) systems. Aquafine systems are found in both the pre-treatment and process areas of the water system. While commonly found in microbiological inactivation and ozone reduction applications, our low-pressure (LP), low-pressure high-output (LPHO), and amalgam systems also can be found in TOC (total organic carbon) reduction and chloramine reduction applications. ChloRid®, for chloramines reduction equipment, utilizes medium-pressure (MP) technology with a reduced footprint and provides dose and is cost efficient.
UV technology for water treatment has several inherent advantages. Nothing is added by UV light to the water stream such as color, odor, flavor, or by-products. UV technology is a fast, efficient, and cost-effective solution.
Trojan Technologies offers validated systems, providing UV lamp and NIST traceable UV sensor validation with certificates, as well as Bioassay amalgam technology. All systems comply with cGMP and FDA requirements, and sanitary connections conform to DIN and USDA 3A standards. Select models carry the marks of cULus, CE and ANSI/NSF and can be mounted horizontally or vertically, or in skid mounted systems, maximizing installation flexibility and preserving floor space.
Applications for UV
This is the most common application of UV light in water treatment. A pharmaceutical water system could have several locations where UV equipment would be installed. Some typical locations of installation would be post-carbon filter and pre-RO (reverse osmosis). When installed downstream of the carbon bed and/or directly upstream of the RO unit, a UV system can significantly reduce the microbial counts by inactivating the microorganisms present in the influent stream. Inactivation is also recommended for the process distribution loop and pre storage tank. Learn more about UV Treatment.
The USP 31 regulations require an upper limit of 500ppb for TOC for both USP Purified Water as well as for WFI. Aquafine systems use a powerful 185nm wavelength appropriately sized and designed to meet this application. Learn more about TOC Reduction.
Ozone is commonly used in the pre-treatment area of a water system, as well as for sanitizing process and recirculating systems. Prior to the point-of-use, the residual ozone needs to be reduced to ensure the process water is not compromised. Because it is a fast-acting mechanism, UV technology is the preferred method for this application. After considering the appropriate variables, a properly sized UV unit can be guaranteed to reduce the ozone to non-detectable limits, ensuring the integrity of the process and the product. A dosage of 90 mJ/cm2 is recommended for reduction of ozone residuals of 1.0ppm. Learn more about Ozone Reduction.
While the addition of chloramines to municipal water may control microorganism levels, they have undesirable effects on the degradation of membrane filtration or RO. But popular methods of removal, such as carbon beds or chemical injection, have proven to be problematic. Sodium metabisulfite involves replacing one chemical with another and creates food for microorganisms, while carbon beds can be inefficient, vulnerable to channeling, and provide breeding grounds for microorganisms. Aquafine pioneered the technology of chloramines reduction utilizing UV light in the pre-membrane filtration or RO make-up water stream. Learn more about Chlorine and Chloramines Reduction.
*Specific UV systems manufactured by Trojan Technologies have been validated through microbial testing. Through this testing, performance data has been generated for UV dose delivery to treat Escherichia coli (E. coli ), fecal coliform, Poliovirus, Cryptosporidium, Giardia, and Adenovirus.
