{"product_id":"develop-and-demonstrate-fundamental-basis-for-selectors-to-improve-activated-sludge-settleability","title":"Develop and Demonstrate Fundamental Basis for Selectors to Improve Activated Sludge Settleability","description":"Successful operation of the activated sludge process relies heavily on the ability to effectively separate mixed liquor into return activated sludge (RAS) and a high quality final effluent. Solids separation efficiency is dictated in large part by the relative population of floc-forming and filamentous microorganisms present in the activated sludge. During normal operation, mixed liquor will be composed primarily of floc-formers with relatively low levels of filamentous organisms. Some population of filamentous organisms is necessary to promote the formation of larger flocs and prevent development of a \"pin-floc\" condition, which often results in high effluent turbidities (Jenkins, 2004). However, when conditions favoring the growth of filaments over floc-formers occur, a condition commonly referred to as filamentous \"bulking\" may occur.
