Water treatment plants use different methods to filter contaminants from wastewater. For many, ultrafiltration technologies offer a way to produce high-quality finished water. However, they may not be right for every treatment facility.
Problems Associated With It
Unfortunately, ultrafiltration technologies have drawbacks that make them unsuitable for some treatment facilities. These negatives include:
- Recirculating water — Contaminants cannot be removed from wastewater in one pass through filtration membranes. Therefore, it must be recirculated until all solids are removed.
- High energy input — The continued circulation of wastewater and high pressure required to push it through filtering membranes requires a large input of energy. This can make ultrafiltration cost-prohibitive for some facilities.
Benefits of Using Ultrafiltration
There are also many benefits of using ultrafiltration in wastewater treatment. First, it produces consistently high-quality water regardless of the quality of input wastewater. This is important for treatment facilities that must reliably produce potable water.
Additionally, it does this without the need for added chemicals. This is critical as some of the chemicals traditionally used in water treatment have known negative effects.
There are pros and cons of using ultrafiltration in wastewater treatment processes. Whether it is a viable technology for your facility will depend on the availability of resources and demand for high-quality outflow water.
