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 […]
As we flush our toilets and run our sinks daily, wastewater gurgles into an unseen underworld of aging pipes, pumps, and treatment plants. This intricate infrastructure forms the backbone of our nation’s sanitation, collecting sewage from homes and buildings to process over 34 billion gallons daily. Yet cracking pipes, overflowing sewers, and outdated plants plague […]
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 […]
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 […]
Circular clarifiers are a critical component in the wastewater treatment process, serving an essential function in both municipal and industrial treatment systems. They are designed primarily to remove solid particulates by sedimentation. The process exploits the density difference between the suspended solids and water, allowing the solids to settle at the bottom of the tank, […]
Drum filters play a crucial role in the wastewater treatment process, providing a mechanical filtration solution that is both effective and reliable. These filters work by trapping solids as wastewater passes through a rotating drum that is covered with a filtering screen or fabric. Designed to handle a wide range of waste streams, drum filters […]
