Influent Wastewater Characteristics

Nov 20, 2020 This post will provide data/tables to give you a starting point when it comes to evaluating influent wastewater characteristics in the absence of plant-specific data. In my own work I make reference to the textbook data tables shown below to compare data I generate in-the-field to "expected" or "typical" data. As a specific example of how I use the textbook influent wastewater tables, I was at

Defining Hazardous Waste: Listed, Characteristic and Mixed

A solid waste is a hazardous waste if it is specifically listed as a known hazardous waste or meets the characteristics of a hazardous waste. Listed wastes are wastes from common manufacturing and industrial processes, specific industries and can be generated from discarded commercial products. Wastewater treatment sludge from the

The effect of wastewater cations on activated sludge

The data showed that WWTPs contained highly varying concentrations of Na+, Al, and Fe in the wastewater and that these cations were responsible for differences between WWTPs as to sludge dewatering rates and effluent quality. In general, a high influent Na+ concentration caused poor sludge dewatering and effluent characteristics.
