Spectrophotometry is a well-established analytical method, which has been used for decades in chemistry, physics, biochemistry, and chemical engineering for quantitative analyses.
The Leopold Type 360 Underdrain uses a modular lateral design to simplify installation. Unique hold-down brackets secure the laterals and enable service to individual underdrains through its innovative bolt down system.
This guide will help lab managers understand risks and best practices as they develop training for CO2 incubator users and establish a preventive maintenance program and setup criteria.
As water utilities migrate toward remote system monitoring and real-time control, the risks associated with cybersecurity tick upward as well. While the rewards of digitalization offer real promise, the associated complexity and security concerns pose corresponding risks. That is why it is important to have an overall risk-management process for the organizational level, the business process level, and for the information system and data levels as well.
The purpose of source water monitoring is to enable drinking water treatment facilities to identify changes in water quality, implement treatment strategies based on the characteristics of the water, optimize the treatment processes, and take preventative actions to protect the source water from intentional and accidental contamination.
A potable water plant in Eastern Angelina County, Texas, serves over 2,000 rural customers.
Ozone disinfection has long been a critical process in the wastewater treatment industry. And, because ozone is relied on so heavily to oxidize a wide variety of potential wastewater contaminants, water quality analysis during the disinfection process is paramount. Once the ozone process itself is understood, its water quality ramifications and the quality parameters that offer insight into its efficacy can be analyzed and taken into account.
More than 7,000 islands of the Caribbean Archipelago are scattered over a million-square-mile area between North and South America. Some smaller islands are naturally dry, but some volcanic islands — like Grenada and St. Lucia — are well forested and provide significant water catchment to support spring water and surface water. But, as populations, agriculture, and industry grow, desalination is becoming more attractive as a water source throughout the entire region.
For some water providers, carefree days of producing pure, fresh water from groundwater sources are long gone. Years of evolving chemical complexity, industrial operations, and short-sighted disposal methods have taken a toll on groundwater sources. The lowering of maximum contaminant levels (MCL) for contaminants such as chromium and the drilling of new wells into different geologic structures add to source water pressures. Fortunately, new technologies are helping water providers make the best of a challenging situation across a wide range of contaminants.
In the Semiconductor industry, raw water is treated in two steps; the first treatment is used to produce “make-up water” and the second phase involves turning make-up water into ultrapure water. This ultrapure water is then used for the final rinsing of fabricated wafers.
