Description:
Zenon Environmental Systems (Zenon) has developed the ZenoGem™ process to remove organic compounds from wastewater by integrating biological treatment and membrane-based ultrafiltration. This innovative system combines biological treatment to remove biodegradable organic compounds with ultrafiltration to separate residual suspended solids from biologically treated effluent. Zenon claims the technology reduces organic contaminants in wastewaterto nondetectable levels, improves effluent quality, and reduces the quantity of sludge for disposal. The major components of the ZenoGem™ system are an influent holding/equalization tank, an enclosed biological reactor (bioreactor), a pH buffer tank, a nutrient solution tank, an ultrafiltration module, an air blower, an off-gas carbon filter, a permeate carbon filter and process, feed, and metering pumps (Figure 1). A pilot-scale ZenoGem™ system, contained in an 8-ft by 48-ft ZenoSite™trailer, was used for the demonstration.
