Abstract
Lancaster, Pennsylvania has two practically new, activated sludge type sewage treatment plants, known as the North Plant and the South Plant. The two plants are identical in type, number and size of units, although, due to topographical conditions, the physical arrangement of the units is different. Considerable trouble has been experienced with bulking of the sludge at the South Plant. The report discusses an analysis of the problem to find its cause.
