NUTRIENT REMOVAL RESOURCES
How To Utilize Electrocoagulation For Efficient Phosphorus Removal In Wastewater
In this article, we will discuss what phosphorus is, the effects of elevated phosphorus levels on an ecosystem, and how innovative electrocoagulation technology can be sustainably used for effective phosphorus removal in wastewater and water sources.
Your Sewage Is Valuable Muck
A world without phosphorous is a world without life. But phosphorous is a finite resource, so researchers are recovering it from sewage.
Sidestream Enhanced Biological Phosphorus Removal Made Easier
Some excellent progress has been made in recent years on sidestream enhanced biologic phosphorus removal, but a current project promises to advance the practice even further.
Nutrient Sensor Action Challenge Winners: Data And Decisions To Manage Excess Nutrients
Nutrients in the environment from excess nitrogen and phosphorous can result in negative impacts on water quality. EPA is improving nutrient management by incentivizing the development of low-cost technology solutions, such as nutrient sensors, in collaboration with USGS, USDA, NIST, NOAA, and the U.S. Integrated Ocean Observing System (IOOS).
WRF Hosts Capitol Hill, State-Of-The-Science Briefing On Harmful Algal Blooms
To make informed decisions about how to limit exposure to cyanotoxins, utilities need information to select and implement a comprehensive and technically sound management approach. The Water Research Foundation (WRF) has been actively involved in developing effective innovative solutions to help utilities address this challenge and protect public health.
Aerobic Treatment Unit (ATU) System Design Tips And Operations Variables
Providing a suitable environment for microorganisms to treat wastewater is what aerobic treatment units (ATUs) are all about. These advanced systems outshine alternatives on tight lots where there is no room for conventional treatment and on sites with poor soils, shallow vertical separation distances to limiting conditions, and horizontal setback restrictions. Some systems can be designed for the treatment of high-strength wastewater or where total nitrogen removal is required.
Aerobic Digester Reduces Nutrient Return And Improves Energy Efficiency
Faced with rising operational costs due to increasing energy and chemical prices, as well as stricter effluent permit limits, many operators and engineers are turning to performance optimizers and controls automation to enhance treatment processes and reduce operating costs while limiting capital expenses.
Understanding And Coping With Struvite/Vivianite Formation In WWTPs
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.
EPA Uses Floating Vegetated Islands To Remove Excess Nutrients From Water
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.
World’s Largest Denitrification Plant Helps Tampa Bay Reduce Nutrient Pollution
Nutrient pollution is getting worse in many estuaries throughout the United States, especially those on the heavily populated East Coast.
