Tetra Tech’s 30-page Guide to Microscopy and Staining of Activated Sludge by Ron Schuyler, is now available for individual purchase. The book is also included with Tetra Tech’s Bacteriological Stain Kit.

This guide is the perfect reference for wastewater professionals analyzing activated sludge with a microscope. This illustrated book includes chapters on sample collection and transport, equipment, microscope operating procedure, preparation of the specimen, staining, and examining your mixed liquor, as well as references and a two-page color plate of examples.

Here is a sample from the book:

"Experience from presenting a number of courses on wastewater treatment microbiology suggested that students need a simple list to assist them in getting started with microscopic examination of filamentous microorganisms. This kit contains the stains most commonly used in identifying filamentous microorganisms and includes the common gram stain and the less common Neisser, PHB and sheath stains. It also contains glass slides, cover slips and immersion oil to help you get started."

Based on requests from students, Tetra Tech is also providing in this document a basic reference for using the microscope to evaluate activated sludge. The following sections discuss sample collection and transport, microscopic equipment requirements, operating procedures, specimen preparation, staining and mixed- liquor examination."

This essential book is now available separately from the Bacteriological Stain Kit for $12.95 plus shipping and handling.
