Veolia extends water reuse process for leading Qatari dairy producer

Following the first stage completed in 2020, Qatar’s leading dairy producer Baladna renewed its trust in Veolia Water Technologies to extend the wastewater treatment capacity at its farm in Al Khor, north of Doha. Baladna is home to over 24,000 cows that are spread over 2.6 million square meters, and will now recycle 22,000 m3/day of wastewater. Veolia Water Technologies is working with Baladna Food Industries to support their sustainability plan and recycle their wastewater. The partnership started in 2020 with the design and construction of a 6,000 m3/d wastewater treatment plant, allowing for the treated water to be reused for irrigation within the farm and, following further treatment by reverse osmosis, to spray and cool the cows during hot summer months. Based on this successful

Advanced Pipe Freezing Technology Reduces Maintenance Costs

Applications of electrodialysis

Conventional electrodialysis is today commercially by far the most relevant ion-exchange membrane separation process. Electrodialysis was first developed for the desalination of brackish water to produce potable water. In this application, electrodialysis is replaced today to some extent by other membrane processes such as reverse osmosis and nanofiltration. Nevertheless, water desalination is still the most important large-scale application of electrodialysis. But other applications of electrodialysis in the food, the pharmaceutical and chemical industry as well as in wastewater treatment are gaining increasing importance. Another large-scale application of electro-dialysis is the preconcentration of seawater for the production of table salt. Some of the more important large-scale

Corrosion Inhibitor Water Treatment Chemical

Corrosion inhibitors are chemical products which, when added to water or to any other process fluid, slow down the rate of corrosion. They are normally classified as: anodic, cathodic, film-forming and oxygen-absorbing agents depending on their mode of action. The effectiveness of most corrosion inhibitors is

What is Ultrafiltration? How an Ultrafiltration Membrane Works

Ultrafiltration (UF) uses standard home water pressure to push water through a semipermeable membrane and remove any contaminants. Unlike reverse osmosis, ultrafiltration retains minerals in the water, while filtering out bacteria, viruses, and parasites.

Treating Wastewater with Microorganisms

Biological Treatment What is a biological wastewater treatment system? Biological wastewater treatment harnesses the action of bacteria and other microorganisms to clean water. Wastewater typically contains a buffet of organic matter, such as garbage, wastes, and partially digested foods. It also may contain pathogenic organisms, heavy metals, and toxins. What method is better and newest for biological treatment of wastewater? Overall Aerobic treatment treatment of wastewater is a better option. Anaerobic degradation followed by aerobic is best suited biological wastewater treatment strategy. During anaerobic degradation, most of the recalcitrant molecules are broken down into smaller ones. What are the advantages of biological treatment? Compared to other treatment methods, biological

Global Wastewater Treatment Market to 2030

The global wastewater treatment market was valued at USD 250.38 Billion in 2021 and is forecasted to reach USD 462.49 Billion by the year 2030. The market is anticipated to register a CAGR of 7.41% over the projected period. Wastewater treatment is a step-by-step procedure of converting wastewater into usable water,

Facing Water Scarcity with Hybrid Desalination Technologies

KIST researchers have created solar and hydrothermal energy-based membrane distillation techniques. By using these specialized membrane distillation technologies for geographical climate applications, system efficiency is expected to be maximized. Human survival depends on access to clean water. The amount of freshwater that can be utilized for drinking, however, is less than 3%. Around 1 billion people globally lack access to clean drinking water, and the number is projected to increase to 1.4 billion by 2050, according to research released by the World Meteorological Organization. Water scarcity could be resolved using saltwater desalination technology, which creates fresh water from salt water. Researchers at the Korea Institute of Science and Technology have created a hybrid membrane
