1. Introduction The oxidation ditch is a modified activated sludge biological treatment process that utilizes long solids retention times (SRTs) to remove biodegradable organics. Oxidation ditches are typically complete mix systems, but they can be modified to approach plug flow conditions. Ideally suited for small- to medium-sized municipal wastewater treatment plants, these systems are renowned […]

Introduction Virginia’s wastewater infrastructure represents some of the most advanced treatment technology in the United States, driven largely by the stringent nutrient reduction mandates of the Chesapeake Bay Preservation Act. With a growing population of over 8.7 million and a geography ranging from the tidal coastal plains to the mountainous Blue Ridge, the state’s engineering […]

Effective Wastewater Treatment Strategies for Operators and Engineers Advanced Biological Treatment Processes Did you know that biological treatment processes can reduce wastewater pollutants by up to 90%? That’s not just impressive; it’s a game-changer for municipalities and industries alike. When it comes to treating wastewater, these advanced methods are like having a secret weapon in […]

Advanced Phosphorus Removal Methods in Wastewater Treatment Introduction In the ever-evolving landscape of wastewater treatment, the quest for efficient and sustainable phosphorus removal techniques is at the forefront of environmental engineering discussions. As municipalities strive to meet stringent regulatory standards while juggling budget constraints, the demand for innovative phosphorus removal solutions has never been more […]

BNR Wastewater Treatment Plant: A Comprehensive Overview Introduction As the global population continues to rise, the management of wastewater has become increasingly critical. Wastewater treatment plants (WWTPs) are frontline defenses in protecting water quality and public health. Among these facilities, the BNR (Biological Nutrient Removal) wastewater treatment plant stands out for its innovative methods of […]

Alum plays a crucial role in wastewater treatment, helping to clean and purify water before it’s released back into the environment. This chemical compound has been used for over a century in various water treatment processes. Alum treatment of stormwater runoff consistently achieves 85-95% reduction in total phosphorus, 65-75% reduction in total nitrogen, and 95-99% […]

Anoxic zone wastewater treatment is an important part of many modern water cleaning systems. This method uses areas with no oxygen to remove harmful chemicals from dirty water. It works together with other parts of the treatment process to make water safe and clean. Anoxic zones in wastewater plants help change nitrates into nitrogen gas, […]

Struvite buildup in wastewater treatment plants can cause major headaches for operators. This crystal-like substance forms when certain nutrients mix in the right conditions. It clogs pipes and equipment, reducing system efficiency and increasing maintenance costs. Removing struvite from wastewater is crucial for keeping treatment plants running smoothly. There are several methods to tackle this […]
