Harmful algal blooms — the overgrowth of algae in water — are a major problem across the nation. Blooms occur when excess nutrients (nitrogen and phosphorus), combine with sunlight, and warm temperatures in water bodies. They can cause severe, negative impacts on aquatic ecosystems, the economy, and human health.
While San Diego has a reputation for beautiful weather in a sunny seaside setting, its growing population in the southernmost area of rain-starved California is a recipe for trouble in paradise. That challenge has spurred the creation of Pure Water San Diego — a multi-phase, multi-year program with the goal of using recycled water for up to one-third of San Diego’s water supply by the year 2035.
Wastewater professionals are under constant pressure to cut costs and improve sustainability. At the same time, they’re responsible for meeting ever more stringent regulations. Continued improvements in wastewater treatment processes are essential for utility leaders to meet these goals.
Wastewater treatment facilities can be designed for physical and biological removal of numerous contaminants. Each plant is unique, yet nearly all wastewater plants must provide disinfection before discharging or reusing the effluent.
Guided wave radar technology provides accurate and reliable level and interface measurement in effluent treatment areas, ensuring regulatory compliance and reducing costs in wastewater applications.
Everything may be bigger in Texas, but there is more of everything in New York City — including biosolids, which require smart, sustainable management.
No utility wants to enact an emergency plan, but every utility should have one in place.
It’s important to start with the fact that this is not a regulatory test. This technology won’t replace any required compliance tests and the results are not reportable, which is actually a great benefit to our users. While regulatory testing is important, compliant does not necessarily mean clean.
Protecting public health and the environment by treating and disinfecting water and wastewater is a global endeavor. India is no exception, and with a rise in population and industrialization, protection of water resources is critical.
Reliable and effective disinfection is a cornerstone of water and wastewater treatment, needed to protect public health. Most drinking water utilities are required to maintain a minimum disinfectant residual in the distribution system. This ensures adequate chemical was applied and remains in the system to kill pathogens. The most commonly used disinfectants — chlorine gas and bulk sodium hypochlorite — require operators to regularly handle these hazardous chemicals.
