Packed column DAF, or Dissolved Air Flotation, is an innovative water treatment technology that efficiently separates contaminants from water. DAF systems are particularly effective for the removal of solids, oils, and greases that are lighter than water and thus can be floated to the surface with the aid of fine air bubbles. Packed column DAF […]
Wastewater treatment is essential for protecting water resources and human health, and microscreens play a critical role in this process. Microscreens are fine screening devices used in wastewater treatment to remove small particles, a process pivotal for protecting downstream processes such as biological treatment and disinfection. The technology behind microscreens includes rotating drum screens or […]
Zone settling is a crucial phase in the wastewater treatment process, which involves the separation of suspended solids from water. This process is based on the differential settling rates of particles under the influence of gravity. In the context of wastewater treatment, zone settling aids in concentrating the solid particles, thus enabling the removal of […]
Ozonation is a water treatment process that leverages the power of ozone, a potent oxidizing agent, to eliminate various contaminants from wastewater. Traditionally used for disinfecting drinking water, its application has expanded to treat municipal and industrial wastewater. Ozone is particularly effective against bacteria, viruses, and organic compounds, often as a tertiary treatment step to […]
Secondary clarification is an integral step in the wastewater treatment process, focusing on separating biological floc or sludge from the treated water after the primary treatment and biological processes have taken place. This phase is crucial as it determines the quality and clarity of the effluent, leading to the release of safe water back into […]
Effluent discharge refers to the flow of wastewater—treated or untreated—that is released into natural water bodies from various sources including industrial, commercial, and residential establishments. The characteristics of this effluent can vary widely based on the source and the types of contaminants present, ranging from organic matter and nutrients to chemicals and thermal pollution. The […]
