NUTRIENT REMOVAL RESOURCES

• Proactive WWTP Design And Innovation Improves Health Of Chesapeake Bay Watershed

  Read about the $568 million, decade-long upgrade of a Water Pollution Control Plant that would expand the plant’s capacity from 30 mgd to 40 mgd while also reducing nitrogen and phosphorous to the limit of technology.

• Evoqua's Orbal System For Biological Nutrient Removal

  Discover how a fast-growing community's new WWTP meets new tighter limits on ammonia, phosphorus, and nitrogen for future growth.

• When Density Is Desirable

  Infrastructure intensification through densification and granulation can help utilities meet nutrient management goals with minimal investment through retrofit.

• Sustainable Clarification In Food And Beverage Operations

  Companies within the food & beverage industry generate significant quantities of wastewater each day. For example, a 16 oz. can of beer is about 90-95% water; however, to make that can, beer producers utilize approximately 7 times this quantity. About 2/3 to 3/4 of the water is typically discharged as wastewater to a municipal sewer system.

• To Reduce Harmful Algal Blooms And Dead Zones, The U.S. Needs A National Strategy For Regulating Farm Pollution

  Midsummer is the time for forecasts of the size of this year’s “dead zones” and algal blooms in major lakes and bays. Will the Gulf of Mexico dead zone be the size of New Jersey, or only as big as Connecticut? Will Lake Erie’s bloom blossom to a human health crisis, or just devastate the coastal economy?

• Biotechnology Innovations Extend Life, Resilience Of Wastewater Infrastructure

  In the daily rush to ensure that all the mechanical, electrical, and operational procedures are followed — monitoring inflow volumes and organic/nutrient loads; servicing and maintaining motors, pumps, and other electrical and mechanical equipment; maintaining chemical treatments to ensure effluent compliance — it is too easily forgotten that wastewater treatment is primarily a biological process.

• EPA Researchers Develop Tool That Helps Water Quality Managers Meet Nutrient Load Targets

  Nutrient pollution is one of America’s most widespread, costly, and challenging environmental problems. This pollution can occur when excess amounts of nutrients, such as nitrogen and phosphorus, run off from land into streams, rivers, lakes, and other water sources. To help water quality managers reduce nutrient pollution, EPA researchers developed the River Basin Export Reduction Optimization Support Tool (RBEROST), a regional online tool currently available for the Upper Connecticut River Basin that provides low-cost solutions to meet nutrient load targets.

• Optimizing The Biological Process With Claros Process Management

  The Wastewater Treatment Plant of Barstow, California (USA), sits in a challenging geographic and demographic position on a straight line between Los Angeles and Las Vegas. Operating a biological nutrient removal system, the plant treats 2.1 million gallons of water per day and discharges into percolation ponds. Kody Tompkins is the Chief Plant Operator of the facility.

• Community Wastewater Treatment Options Expand With Decentralized Treatment Approaches

  Sometimes conventional wastewater treatment solutions won’t work for a given application, and sometimes a nonconventional approach is simply the better choice for high-quality, cost-effective performance.

• Riviera Utilities WWTP Upgrades To State-Of-The-Art Aerobic Granular Sludge Technology

  Instead of taking the traditional approach of adding an additional oxidation ditch to increase treatment capacity, Riviera Utilities had the desire to “future-proof” the plant and prepare to meet more stringent effluent requirements.

• Biolac Long Sludge Age Treatment Combined With MRI Plate Settlers Achieves Low Nutrient Limits

  The Tri-Lakes Wastewater Treatment Facility located in Monument, CO, receives flow from the Woodmoor, Palmer Lake, and Monument Sanitation Districts. The plant discharges treated effluent to Monument Creek, which is within the Fountain Creek Water Shed. Originally, the Tri-Lakes facility consisted of a three-cell lagoon. This was replaced by a two-basin Biolac Wave-Ox system, which was installed in 1990 and later upgraded in 1998 to a three-basin system with a capacity of 4.2 MGD.

• Complete Grit Removal And Sludge Screening Solution Protects And Optimizes Plant Performance In Conway, Arkansas

  An aging wastewater treatment plant had the potential to impact the water quality of a 6,700 acre man-made fishing lake near Conway, Arkansas. The city needed a new treatment facility that was consistent with pending permit limits.  Read the full case study to learn more.

• Side-Stream SDOX® Systems Enhance Biological Function And Treatment Capacity

  Wastewater from the meat processing facility is treated using a sequence batch reactor and an aerobic lagoon that discharges to surface waters following treatment. The facility replaced surface aeration equipment with two, 350-HP the “no-splash,” side-stream SDOX systems retrofitted to the treatment basin. Read the full case study to learn the results.

• Wastewater Nitrogen Is Causing Ecological Havoc, But The Necessary Innovative Solutions Exist

  The water quality damages associated with excessive nitrogen discharges to our surface and groundwaters that result in life-threatening harmful algae blooms (HAB), the loss of shellfish and finfish, and the degradation of our groundwater drinking water aquifers are now ubiquitous in the U.S. and worldwide. Wastewater nitrogen discharges are typically the elephant in the room when the sources of nitrogen are quantified. Septic nitrogen discharges, in particular, are the primary cause of water-quality/ecological degradation in many, especially coastal, areas.
