An Introduction to Sludge Handling, Treatment and Disposal

COURSE NO: C04-021
PDH CREDIT: 4
An Introduction to Sludge Handling, Treatment and Disposal
Course Highlights

This online engineering PDH course will introduce you to processes and equipment for handling, treating and disposing of sludge produced by wastewater treatment plants. It covers sludge pumping, thickening, conditioning, dewatering, digestion, storage and final disposition. It also discusses loading parameters for gravity thickeners and operational parameters for air flotation thickeners. This course will provide guidelines for chemical conditioning of sludge; and advantages, disadvantages and shortcomings of filter presses, basket centrifuges, and solid bowl decanter centrifuges.  Finally it illustrated the design parameters for aerobic and standard and high-rate anaerobic sludge digesters.

 

This 4 PDH online course is intended for civil, environmental and chemical engineers as well as construction professionals seeking an introduction to sludge handling, treatment and disposal.

Learning Objectives

This PE continuing education course is intended to provide you with the following specific knowledge and skills:

  • Identifying the characteristics, advantages and disadvantages of the four primary types of sludge pumps
  • Recommending pump types for primary, chemical precipitated, trickling-filter, activated, thickened and concentrated sludge
  • Learning about gravity and flotation thickening of sludge, as well as the mass loading guidelines for gravity thickeners
  • Learning about the operational parameters for flotation thickening of sludge
  • Learning how chemical conditioning is used to improve sludge dewaterability and how heat can improve dewaterability of sludge
  • Learning about sludge dewatering using a belt filtration press
  • Understanding the advantages, disadvantages, shortcomings and solutions to problems that may arise with belt filter presses
  • Understanding the design guidelines for sludge drying beds
  • Learning about sludge moisture reduction using vacuum filtration
  • Learning about sludge dewatering using basket centrifuges or using solid bowl centrifuges
  • Understanding the advantages, disadvantages, shortcomings and solutions to problems that may arise with solid bowl decanter centrifuges
  • Learning about plate-and-frame filter presses, as well as manual, semi-automatic and automatic controls for filter presses
  • Learning about continuous and intermittent batch aerobic sludge digestion, as well as anaerobic sludge digestion
  • Understanding the design parameters for aerobic digestion using air, as well as the design parameters for standard- and high-rate anaerobic digesters
