Over the past 10 to 15 years, granular sludge technologies are being more commonly used for treating high strength wastewaters with low suspended solids (SS) concentration due to their inherent advantages. The Upflow Anaerobic Sludge Blanket (UASB) and the Enhanced Granular Sludge Bed (EGSB) are two of the most commonly used granular technologies for treating such wastewaters. Several factors, such as wastewater characteristics, pH, temperature, reactor configuration, nutrients, recycle and other design elements affect performance of UASB/EGSB reactors.

This paper highlights the findings from a general survey of granular anaerobic treatment systems and Triad's experience at two systems in particular in which UASB/EGSB performance was enhanced. Common problems encountered and ways to alleviate or reduce these problems to optimize the system are summarized. Optimization methods discussed include: chemical feed locations, recycle, reactor pH, control of oil & grease, and reactor feed distribution.
