What is the primary function of a pressure filter in water treatment?

The primary function of a pressure filter in water treatment is to remove suspended solids and contaminants. Pressure filters are designed to treat water by passing it through a filter medium under pressure, allowing them to effectively capture and eliminate impurities, such as dirt, debris, and other particulate matter suspended in the water. These filters are especially useful in the treatment of water that has a higher concentration of solids, as they can achieve a high level of filtration efficiency.

By utilizing pressure to force water through the filter media, the system can operate at a higher flow rate compared to gravity filters, making it a preferred choice in many water treatment facilities. This capability is crucial for maintaining water quality and ensuring that the treated water is safe for consumption and other uses.

The other choices do not align with the primary function of a pressure filter. For example, while chlorination is a method for disinfection and not the main role of a pressure filter, enhancing taste and odor refers to different types of water treatment processes, such as carbon filtration, and regulating water temperature involves separate heating or cooling systems rather than mechanical filtration.
