Chemically enhanced high rate settling (CEHRS) shows promise in removing harmful compunds such as pharmaceuticals and consumer products from wastewater.

Veolia's solution to the ever-changing, and increasingly stringent, environmental regulations that frequently require upgrading a primary treatment facility (i.e. only screening and primary clarification) or secondary treatment facility (biological treatment for removal of BOD and TSS) to tertiary treatment and the removal of BOD, TSS and Total Nitrogen (TN).

This paper presents results from the study of the Dynamic Phase Control strategy at the North Cary WRF, NC. The study showed that process can be significantly optimized by incorporation of Dynamic Phase Control.

The key distinguishing characteristic of the BAF process is that the microorganisms live in a biofilm attached to a media surface, rather than being freely suspended in the wastewater.

Thermal hydrolysis solves numerous challenges at a wastewater facility including increasing treatment capacity, reducing biosolids handling, increasing biogas production to reduce energy utilization, reduce operation cost for biosolids processing, produce renewable bio-fertilizer.

The Hydrotech Discfilters remove the precipitated phosphorus as well as phosphorus bound in the TSS from the upstream BNR process.
