IFAS Optimizes Use of Existing Infrastructure and Upgrades Performance
Abstract
Small footprint technologies, such as the integrated fixed film activated sludge (IFAS) process, provide unique solutions for biological nutrient removal (BNR) facilities that face site constraints, expansion challenges, and/or the desire for a high quality effluent. The Yucaipa Valley Water District (YVWD) selected IFAS to expand the Henry N. Wochholz wastewater treatment plant (WWTP) capacity from 15140 m3/d (4 mgd) to 30280 m3/d (8 mgd) and to meet a total inorganic nitrogen (TIN) permit limit of 6 mg/L based on a 12-month average. The paper will discuss startup challenges with respect to the IFAS basins loading, media, aeration control as well as foaming issues. It will also provide information on current plant performance and operations.
