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 […]
From the gas pump to the synthetic fertilizers that help feed the world, petroleum products facilitate almost every aspect of modern life. But this ubiquitous fossil fuel comes with an overlooked and mounting environmental toll – for every barrel of crude oil extracted, an astounding 10 barrels of salty, contaminated wastewater called “produced water” surfaces […]
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 […]
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 […]
