As urban populations swell around the globe, an overlooked byproduct of our modern sewage systems is accumulating at an astonishing pace – wastewater sludge. This problematic solid waste is highly nutrient-rich yet challenging to manage sustainably. But innovative resource recovery techniques are now transforming sludge from an environmental liability into a circular economic asset supplying […]
As China’s capital Beijing continues its unprecedented urban expansion, the city’s environmental and public health demands grow in turn. With over 20 million residents, Beijing generates staggering volumes of sewage and wastewater that must be treated and discharged responsibly. At the forefront of Beijing’s wastewater infrastructure stands the Beixiaohe Treatment Plant – an engineering marvel […]
Water treatment company H2O Innovation Inc. recently announced the acquisition of Itasca Systems Inc. in a $24 million deal. Itasca Systems provides specialized water systems engineering and technical services related to membrane filtration and other treatment technologies. This strategic purchase allows Canadian cleantech leader H2O Innovation to expand its engineering and system design capabilities in […]
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 […]
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 […]
Bar screens are essential components in wastewater treatment plants, serving as the first line of defense in the filtration and treatment process. They are installed at the entrance of the treatment facility to physically remove large objects such as sticks, rags, and plastic materials from the wastewater stream. This preliminary step is crucial because it […]
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 […]
