Based on wastewater properties, various types of mineral buildup can affect wastewater treatment plant (WWTP) piping. With their impacts on plant energy efficiency and potential restriction of throughput capacity, keeping pipes free-flowing is an important aspect of WWTP operations. Here’s guidance for coping with two common problems associated with phosphorus concentrations in wastewater — struvite and vivianite.
Reverse osmosis (RO) systems offer power plant owners and operators a reliable and well-proven water treatment solution. However, designing and caring for an RO system requires a thorough understanding of a plant’s water supply and the technology’s capabilities. Part one of this series will review the importance of water samples and pilot studies as plant engineers begin to design an RO system to match their needs.
Basic construction activities today are more complex than ever when it comes to environmental concerns. Dewatering is a common necessity for contractors and developers today. In addition to ensuring a safe construction site, contractors must be aware of groundwater disposal constraints and regulations.
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.
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.
