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 […]
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 […]
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 […]
Agricultural wastewater is a significant byproduct of farming activities, encompassing various types of water that have been used or affected by agriculture. It includes runoff from fields, pollutants from livestock, and drainage from irrigation, carrying substances that can impact water quality if not managed carefully. The challenges associated with managing this wastewater are surging due […]
In the domain of wastewater treatment, the use of band screens plays a crucial role in the initial stages of the cleaning process. Band screens are fine screening equipment that efficiently removes debris and solid waste from the flow of wastewater. They consist of a series of panels or bands, which form a continuous loop […]
In the realm of wastewater treatment, basket screens play an integral role in protecting the environment and extending the lifespan of treatment facility equipment. These screens are specifically designed to remove debris and other solid materials from wastewater before it proceeds to the more sensitive phases of the treatment process. They operate by capturing solid […]
