Federal law mandates low-lead brass in 2014, but come July 1, 2012, ANSI/NSF 61 Annex F takes effect, lowering lead TAC to 5 ppb. Some brass now ANSI/NSF 61-certified might not comply. Deplete existing 85-5-5-5 brass stocks and replace them with low-lead. Add "N" to virtually any Mueller® brass catalog number for low-lead.

Benefits Of IFAS For Enhanced Biological Nutrient Removal (BNR) By Headworks Inc.
One of the major concerns regarding municipal wastewater treatment plant discharge is the rising concentration of nutrient compounds, specifically nitrogen and phosphorus. Nitrogen and phosphorus are the primary causes of cultural eutrophication (i.e., nutrient enrichment due to human activities) in surface waters.
Maximizing Your ROI On Test Equipment By Heather Rekalske, Myron L Company
In today’s economic climate, it’s tempting to want to buy the cheapest test equipment you can. But, how can you tell what the true cost of test equipment is? You have to consider how widely your water and chemical consumption will vary, just as the readings on your instrumentation do.
A Primer On Energy Efficiency For Municipal Water And Wastewater Utilities By The World Bank
This primer is concerned with energy use and efficiency of network-based water supply and wastewater treatment in urban areas. It focuses on the supply side of the municipal water cycle, including the extraction, treatment, and distribution of water, and collection and treatment of wastewater — activities which are directly managed by water and wastewater utilities.
WEDECO’s renowned reliability and unmatched energy efficiency come together to form the WEDECO Spektron Series Closed Vessel UV Reactor. EPA and DVGW compliant, the upgraded features include the patent pending OptiCone™ flow diverter and optional automatic wipers for high fouling/scaling water. These additions create optimum hydraulic conditions inside the reactors resulting in enhanced flow capacity per lamp and reducing needed maintenance, giving you a clean water disinfection system that provides energy efficiency and lower costs.
