Access to safe, clean drinking water is a basic necessity that billions around the world still lack. Contaminated water continues to spread life-threatening diseases like cholera, dysentery and diarrheal infections – a leading cause of childhood mortality in developing nations. While large-scale sanitization infrastructure has expanded, many remote and impoverished communities remain without reliable water […]
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 […]
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 Yet cracking pipes, overflowing sewers, and outdated plants plague […]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 […]
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 […]
