The cities of Littleton and Englewood, CO, just south of Denver, share a wastewater plant — the Littleton/Englewood advanced wastewater treatment (AWT) plant located in Englewood. The 7886 m3/hr (50-mgd) Littleton/Englewood AWT plant serves more than 300,000 residents in the Denver metropolitan area. The facility also receives sewage from 21 districts within a 75 square mile service area. Plant effluent is discharged to the Denver metro area’s major watershed, the South Platte River.

New RO And Other Techniques Lead To Improved Performance New RO And Other Techniques Lead To Improved Performance

For water utilities facing various water contamination issues, there is no single catch-all treatment. That is why in this recent Water Talk interview Ronit Erlitzki and Doug Craver of AdEdge Water Technologies share treatment options that can be used alone or in combination to address diverse challenges. They introduce a new reverse osmosis (RO) treatment technique capable of raising recovery rates by 20 percent and reducing concentrate volume up to 70 percent vs. conventional RO (depending on water quality). They also explore biological processes for removing nitrate, VOC, ammonia, etc. and treating high brine concentrations in wastewater, plus techniques for resolving ammonia problems in water with high TOC concentrations.

A Modern Approach To Sewer Overflows A Modern Approach To Sewer Overflows

As storm activity continues to grow, utilities are under increasing pressure to mitigate sewer overflows. Building enough storage to handle the excess runoff until it can be treated is no longer practical — in most places, it’s not even feasible to create a large enough space — and the issue will only get worse as storms continue to intensify. Meanwhile, most settling technologies that address overflows require chemicals and a complex process to start up, shut down, and store through off-peak times.

ABOUT WASTEWATER FILTRATION

Wastewater filtration is often part of the tertiary treatment process that involves the final removal of suspended particles from water that has passed through both the primary and secondary treatment phases and immediately precedes disinfection. As the water passes through the filter, residual suspended material and bacteria is trapped in the filter and are removed from the filtered water. Passage can be blocked by physical obstruction, biological action, adsorption, absorption or a combination of ways. Wastewater filtration is usually the final step in the solids removal process.

With regulations increasing around wastewater effluent, the use of ultrafiltration and microfiltration systems in further polishing effluent has grown. Sand or activated carbon filters can provide a media for bacterial decomposition of nutrients, converting nitrates into nitrogen gas. The rise of water reuse applications is also fueling the increasing use of filters during the final polishing stages of the wastewater treatment process.
