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.\u003cbr\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/p\u003e","brand":"Rarewaves","offers":[{"title":"Default Title","offer_id":57874301190518,"sku":"9781843397526","price":169.24,"currency_code":"GBP","in_stock":true}],"url":"https:\/\/www.rarewaves.com\/products\/9781843397526-develop-and-demonstrate-fundamental-basis-for-selectors-to-improve-activated-sludge-settleability","provider":"Rarewaves.com","version":"1.0","type":"link"}
