Desalination, or desalting, refers to processes that remove salts and minerals from saline water to produce fresh water suitable for human consumption or irrigation. As supplies of fresh water across the globe grow scarce while demand continues rising, desalination technologies have become increasingly critical for providing populations with adequate water. Desalting technologies can be separated […]
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 […]
Screw presses play a crucial role in wastewater management, serving as an effective tool for the dewatering of sludges and slurries. These mechanical devices leverage a screw mechanism to apply pressure and separate solids from liquids. Their operation is relatively straightforward but highly dependent on specific variables such as screw speed, the design of the […]
Sand filtration is a widely accepted and effective method for treating wastewater before it is discharged into the environment or reused. It operates by passing wastewater through layers of sand where contaminants are physically captured or biologically treated. The simplicity of design and operation makes sand filters a practical choice for removing suspended solids, reducing […]
Medium Pressure (MP) UV Systems have become a pivotal component in modern wastewater treatment processes, combining efficacy with sustainability. By utilizing ultraviolet (UV) light to disinfect effluents, these systems inactivate pathogens and microorganisms and help in meeting stringent discharge standards. The strategic use of UV light at medium pressure enhances the efficiency of disinfection while […]
Understanding the role of gray water in wastewater management is crucial for the efficient use of water resources. Graywater, essentially the reuse of domestic wastewater from sinks, showers, and washing machines, can significantly reduce the total volume of wastewater requiring treatment. This sustainable practice not only saves water but also lessens the load on sewage […]
Ozone laundry systems represent an innovative approach to wastewater treatment that leverages the power of ozone—a potent oxidizing agent—to sanitize laundry and disinfect wastewater. These systems inject ozone gas into the water, reducing the need for high-temperature water and chemical detergents. By utilizing the natural properties of ozone to break down contaminants, these systems can […]
In the context of environmental sustainability, reuse, and disposal practices play critical roles. Reuse involves repurposing materials or products, which can significantly reduce waste and conserve resources. Meanwhile, disposal is the final action taken for materials that can no longer be effectively used, necessitating strategies that minimize environmental impact. Approaching both practices thoughtfully ensures that […]
Water is the sign of life. A global survey shows that approximately 70% of the earth’s surface is covered by water in the form of oceans, seas, rivers, lakes, etc. Despite being abundant, water is becoming highly scarce due to the growing disparity between freshwater supply and usage. The imbalance between the supply and demand […]
Global engineering and consulting firm Black & Veatch (B&V) announced this week that it has acquired the water business of MJ Gleeson Group, an Australian construction and civil engineering company. This strategic acquisition significantly expands B&V’s water infrastructure capabilities and strengthens its presence across the Asia-Pacific region. MJ Gleeson’s water infrastructure division specializes in designing […]
