NEWater Automatic Backwash Filters
Backwashing, as a water conservative process, is an essential process. NEWater’s Automatic Backwash Filters make use of a series of steps to ensure the efficient functioning of the filtration media. And run until the turbidity of the backwash water is below a standardized value. The steps include service, where the water is being filtered by the media, after that backwash occurs, concluding with a rapid rinse.
The first step that occurs is the service cycle, where the raw water moves through the filters and is treated, by the removal of impurities and contaminants. This is done as the water flows from the top of the filtration tank to the bottom. Over a series of filtrations, the media is likely to clog up, and it is due to this that backwashing is then carried out, and is this process is also referred to as regeneration of the media.
Once it is identified that the filters need to be cleaned, our Automatic Backwash Filters, begin the cleaning process. The water enters a cycle where it flows in a direction that is the reverse of the service flow. The water flows, rather than the top, flows from the bottom of the filter bed to the top, this may be aided by compressed air being pushed up through the media, depending on your need, and as the water flows up, it separates any retained contaminants from the media.
The final step is the rapid rinse stage, where the water again flows from the top of the media to the bottom, thus in the same direction as the initial service flow. But rather than its usual flow, the water is directed to the drain. This helps clear any remaining contaminants and impurities in the tank and also helps repack the filter media to its original condition. This allows your regular filtration process to resume with renewed efficiency.
Our Automatic Backwash Filters are both cost-effective and easily programmable. We provide both highly experienced teams for the installation of equipment, along with comprehensive instructional videos, to alleviate any confusions you may have as a customer of our devices.
