Tucked away in a quiet corner of Arlington County lies an unassuming complex of buildings that play a vital role in maintaining the health and cleanliness of our waterways. The Arlington Waste Water Treatment Plant has been operating since 1959 to treat sewage from Arlington County and discharge clean water back into the environment. On […]
The Eastern Water Reclamation Facility (EWRF) is a crucial wastewater treatment plant providing significant water reuse and environmental services to the Orlando, Florida, region. Owned and operated by the Orange County Utilities Department, EWRF commenced operations in 1986 to help meet increasing wastewater infrastructure demands stemming from rapid Orlando metro population growth through the second […]
As water scarcity intensifies globally, innovative technologies are needed to ensure adequate supply and optimize treatment. Water processes based on osmosis, the natural diffusion of water across a semi-permeable membrane, have generated growing interest for their efficiency, reliability, and environmental sustainability. Engineered osmosis methods like forward osmosis (FO) and pressure-retarded osmosis (PRO) utilize optimized membranes […]
Excess phosphate in water bodies can lead to eutrophication, causing algal blooms that reduce oxygen levels and threaten aquatic ecosystems. Removing phosphate from wastewater, agricultural runoff, and other point sources before they enter natural water systems is an essential strategy for preventing eutrophication. Biochar, a porous carbonaceous material produced by pyrolyzing biomass under oxygen-limited conditions, […]
Ozonation in wastewater is an advanced treatment method that utilizes ozone, a powerful oxidant, to remove a variety of contaminants from water. This process has been employed for over a century, initially focusing on disinfection, but has since evolved to address a wider range of inorganic and organic pollutants. The efficacy of ozonation in improving […]
Lagoons have been a fundamental part of wastewater treatment for communities worldwide, leveraging natural processes to manage sewage and industrial waste. They offer a cost-effective and energy-efficient solution for wastewater management, particularly in small, rural, and tribal communities where resources and infrastructure may be limited. Understanding the various types of lagoon systems and their operational […]
Anaerobic digestion is a biological process that occurs when organic matter is broken down by bacteria in the absence of oxygen. It is a technology that has been harnessed to manage waste, mitigate pollution, and produce biogas – a mixture of methane and carbon dioxide that can be used as a renewable energy source. The […]
Ammonia exchange in wastewater treatment is a critical process for managing nitrogen levels and maintaining environmental safety. High concentrations of ammonia in wastewater can lead to eutrophication in water bodies, a process that depletes oxygen and harms aquatic life. To address this, various technologies have been developed for the efficient removal or conversion of ammonia […]
Anaerobic digestion is a biological process that plays a crucial role in wastewater management by breaking down organic material in the absence of oxygen. This process not only reduces the amount of waste but also converts it into biogas, a renewable energy source comprising primarily methane and carbon dioxide. Wastewater treatment plants around the globe […]
The Activated Sludge Process is a critical part of modern wastewater treatment methods. Through this process, wastewater containing organic matter is aerated in a basin to encourage the growth of microorganisms that consume the organic pollutants. The method vastly improves the quality of the effluent, rendering it safer for discharge into natural water bodies or […]
