DRINKING WATER CASE STUDIES AND WHITE PAPERS

• Meeting The Challenge For Remote Leak Pinpointing

  Ranhill SAJ Sdn Bhd, a subsidiary of Ranhill Holdings Berhad, is an integrated water supply company in Malaysia, involved in the process of water treatment and distribution of treated water to consumers right up to billing and collection. It serves around 3.1 million population and manages 22,175 km of pipes over an area of approximately 19,000k m².

• Liqui-Flux Case Study: Large-Scale Treatment Of River Water For Industrial Use

  Ultrafiltration (UF) is commonly used as a pre-treatment to Reverse Osmosis (RO) to ensure reliable, consistent and efficient operation. As Shandong Hongxin Chemicals Co., Ltd in China recently discovered, this consistency and reliability, along with quick setup and installation times, helped them realize convenience and cost savings.

• To AMI Or Not To AMI: Lessons Learned From Global Omnium's Deployment, And Steps To Success

  Is AMI worth the investment? Where will the ROI come from? How long will it take the water utility to be fully operational after AMI implementation? How can risks be minimized?

• Evolution Of Pipeline Leak Detection

  As the sheer number of pipelines crisscrossing the country continues to increase, there is an urgent need to ensure pipeline infrastructure safety. The age of many of the pipelines and the number of different products flowing makes this a challenging prospect. Now, new technology has been developed that meets the need for reliable protection that complies with regulatory requirements while eliminating false alarms.

• Is Coagulation Followed By Filtration Viable To Remove Arsenic When Raw Water Arsenic Levels Are High? (Loprest)

  A pilot study hoped to demonstrate "proof of concept" if coagulation followed by filtration was a viable technology to remove arsenic when raw water arsenic levels are high.

• Pilot Test For Manganese Removal Using Manganese Greensand

  Filtration rates, run times, backwash procedures, chemical dosage rates, etc. are all established by theoretical calculations and history. Therefore, Loprest’s goal in this pilot study was to conduct uninterrupted operation per bid testing procedures and document the results.

• Aclara RF Network System Stands Up To Hurricane Sandy

  When Hurricane Sandy struck in October of 2012, Aclara's RF network technology, which was installed across New York City's five boroughs, was under pressure to perform effectively. 

• Maximizing Speed And Accuracy In Microbiological Testing

  A quality outcome is only as reliable as the components and processes used to create and test it. When it comes to municipal drinking water, food, beverages, wastewater effluent, and other industrial applications, having reliable microbiological testing reference materials to benchmark quality control (QC) processes is essential. Here are some important points to consider when establishing or managing QC programs.

• Avoiding The High Costs Of Aeration Inefficiency

  Knowing that aeration requirements consume 50 to 60 percent of a wastewater treatment plant's (WWTP) energy bill is one thing. Knowing exactly how and when to tweak aeration output to optimize activated sludge process efficiency with minimal energy waste is an entirely different story.

• Removing Hexavalent Chromium From Groundwater Supplies

  This chromium removal pilot study was conducted for the County of San Bernardino, CA, at their CSA 70 Zone J - Well 5 treatment facility. Chromium in the CSA 70 Zone J – Well 5 raw water source exceeded the current maximum contaminant level (MCL) and was in need of a solution.
