Industrial wastewater encompasses a wide spectrum of water discharge, originating from activities related to manufacturing, processing, washing, and cooling in industrial facilities. It often contains a mix of chemical, biological, and physical pollutants that vary greatly depending on the industry and specific processes from which it originates. These pollutants can have significant impacts on the […]
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 […]
Safe drinking water and effective wastewater treatment are critical for protecting public health and the environment. Chemical technologies play an important role alongside physical and biological treatment methods. This article provides an overview of key chemical processes used, design considerations, and challenges for further improvement. Chemically-enhanced sedimentation (coagulation and flocculation) is used to remove suspended […]
Wastewater from industries and cities is collected and treated by a wastewater treatment plant (WWTP). To put it another way, a WWTP treats water to get rid of waste, grease, floating oils, sand, and any coarse debris that may be present in the water. The treatments get rid of organic and inorganic materials through settling […]
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 […]
Wastewater treatment is a crucial process in ensuring clean and safe water for our communities and the environment. It involves the removal of contaminants and pollutants from wastewater to make it suitable for discharge or reuse. One of the key components in this process is wastewater treatment pumps, which play a vital role in moving […]
Biological treatment in wastewater management is a process that mimics the natural purification mechanisms found in the environment. It involves using microorganisms, such as bacteria and protozoa, to break down organic matter in sewage or industrial effluents. This method is favored for its efficiency in reducing the load of pollutants and its role in the […]
Secondary treatment in wastewater is a vital process that follows the primary treatment stage to purify wastewater further before it is released into the environment or reused. Primary treatment involves the removal of large solids and sedimentation, which reduces the water’s organic load but does not eliminate dissolved organic matter or pathogens. This is where […]
Drum screens are essential components in modern wastewater treatment facilities. They play a pivotal role by mechanically separating solid waste from the liquid stream at the very beginning of the treatment process. Their primary function is to prevent large debris and particulate matter from entering and potentially damaging subsequent equipment or hindering the effectiveness of […]
Screening is a critical first step in the wastewater treatment process that serves to protect the rest of the system from large debris. At wastewater treatment plants, water first passes through screens to remove objects such as rags, paper, plastics, and metals. This is essential not only to prevent physical damage to downstream equipment but […]
