Communities surrounding industrial facilities and municipal operations are directly impacted by foul orders making life unbearable. These smells indicate more than just the presence of nuisance, but rather hazardous air emissions that pose serious environmental and public health threats. Hydrogen Sulfide (H2S)—one of these contaminants—is a flammable and highly toxic gas that is normally known […]
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 […]
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 […]
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 […]
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 […]
In the realm of wastewater treatment, sidestream ozone injection represents a sophisticated method aimed at enhancing water quality through the application of ozone, a powerful oxidizing agent. This technique introduces ozone directly into a sidestream of the wastewater before mixing it back into the main flow. The utilization of ozone plays a crucial role in […]
Ultrasonic irradiation in wastewater treatment is an innovative and emerging technology that employs high-frequency sound waves to assist in the cleansing process. This method utilizes the power of ultrasonics to disrupt the cellular structures of pathogens and compounds, leading to their eventual breakdown. It is increasingly recognized for its potential to enhance the effectiveness of […]
Cascade aerators are a critical component in the treatment of wastewater, serving the primary function of introducing air into the water to increase the dissolved oxygen content. This process is essential for the biological treatment stages of wastewater management, where aerobic bacteria break down organic pollutants. The design of cascade aerators takes advantage of gravity […]
Efficient wastewater management is a critical concern for municipalities and industries around the globe, and rotary fan presses play a significant role in streamlining this process. Rotary fan presses are an advanced dewatering technology designed to separate liquids from solids in sludge, a byproduct of wastewater treatment. By applying steady pressure and rotational movement, these […]
