Essentials of Water and Wastewater Treatment for CPI Operations Guidebook


SKU: ce93 Category:


Treating inlet water so it is suitable for use in the process plant, and treating industrial wastewater so it is suitable for either reuse in the plant or discharge in accordance with all regulatory requirements and sound environmental practices, are major undertakings for all chemical process industries (CPI) facilities.

This Chemical Engineering Guidebook provides a wealth of insight and practical engineering recommendations for professionals involved in water- and wastewater-treatment activities. Some of the engineering articles contained in this guidebook cover mechanical options, such as different options for filtration, to remove particulate matter (with articles covering, for instance, selection, operation and troubleshooting tips for filters and filtration systems and sludge processing).

Other areas focus on biological treatment routes, with engineering articles discussing how to select and optimize the microorganisms needed to degrade organic contaminants and other chemical pollutants, and engineering recommendations for maintaining and troubleshooting activated-sludge systems. Find detail on the complex treatment systems that are available to treat wastewater so it is suitable for reuse as an inlet water source. Additional coverage provides guidance on pumps, valves and piping, all of which are ubiquitous in any water- or wastewater-treatment system design.

As an added resource, several articles included provide practical engineering guidance on project management and cost estimating during capital projects.

Delivered in a PDF format, 158 pages.
