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.\u003c\/p\u003e","brand":"IWA Publishing (Intl Water Assoc)","offers":[{"title":"Paperback","offer_id":47891985039511,"sku":"9781843397526","price":14953.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/3471\/1191\/files\/9781843397526.webp?v=1781185370","url":"https:\/\/atlanticbooks.com\/products\/develop-and-demonstrate-fundamental-basis-for-selectors-to-improve-activated-sludge-settleability-9781843397526","provider":"Atlantic Books","version":"1.0","type":"link"}
