아쿠아 계측 시스템(Aqua Metrology Systems, AMS)은 소독부산물(DBP)의 형성에 대한 실시간 데이터를 제공해 수질 오염물질 검출을 위한 온라인 및 오프라인 분석 기기를 제공했다. 이는 획기적이고 자유롭게 염소의 살균 계획을 평가하는 유틸리티를 보조하기 위함이다. 또한 첨단 수질 정화 시범 프로젝트(Advanced Water Purification Demonstration Project, AWPDP)를 통해 음용수 및 재사용수 제조시 안전성을 확보하도록 했다.

from Aqua Metrology Systems (AMS), a provider of online and offline analytical instrumentation for the detection of water contaminants, to provide real-time data on disinfection byproduct (DBP) formation, aid the utility in evaluating its innovative free chlorine disinfection strategy, and ensure the safety of potable reuse water being used produced at its Advanced Water Purification Demonstration Project (AWPDP).

 

Padre Dam imports 100 percent of its drinking water supply from the Sacramento Bay Delta and Colorado River. Drought conditions and imported water supply challenges have highlighted the need for Padre Dam to explore new possible water sources capable of ensuring a safe and reliable drinking water supply. As a result, the AWPDP began operations in April 2015 at the Roy Stover Water Recycling Facility to evaluate the treatment strategy needed to meet the requirements for potable reuse from recycled water. Once full-scale, it will provide 2,000 to 3,000 acre feet per year -- 20 to 25 percent of Padre Dams drinking water.

 

The AWPDP, using a 100,000-gallon-per-day pilot facility, includes the feasibility testing of the addition of free chlorine, ultrafiltration, reverse osmosis, and advanced oxidation. Free chlorine is a unique application for water recycling facilities and, as such, it is important to test and verify the quality of the potable reuse water created through advanced treatment. The THM-100 monitor is being used to demonstrate the free chlorine strategy and its ability to provide high-quality potable reuse water while limiting the formation of harmful DBPs.

 

"The THM-100 online monitor provides us with immediate and accurate daily reports on THM levels. Monitoring the real-time formation of THMs helps us to ensure we are meeting the pathogen removal requirements for potable reuse," said Al Lau, Director of Engineering, Padre Dam Municipal Water District. "The online monitor continuously measures the THM levels of the permeate water from the reverse osmosis system. Manually collected samples are analyzed alongside the samples taken automatically by the monitor in its online mode."
