Download: Effective Utility Management - A Primer for Water and Wastewater Utilities
Water and wastewater utilities across the country are facing many common challenges, including rising costs, aging infrastructure, increasingly stringent regulatory requirements, population changes, and a rapidly changing workforce. Effective utility management can help utilities respond to both current and future challenges and support utilities in their common mission of being successful 21st century service providers.
Based on these challenges, E…
Download: DISSOLVED OXYGEN MEASUREMENT IN A WASTEWATER TREATMENT PLANT
Monitoring dissolved oxygen is an important part of the activated sludge process. It assists in ensuring that there is sufficient dissolved oxygen in the process for the biological activity to take place, and helps to optimize energy usage through controlled air addition. In some cases, aeration accounts for between 2% and 3% of their annual energy costs. Maintaining a proper level of dissolved oxygen can only be accomplished by using an on-line instrum…

Download: Breakpoint Chlorination Ammonia Removal Thesis
Numerous wastewater treatment processes are currently available for nitrogen removal or ammonia conversion to nitrate.
- Those that are economically feasible rely mostly on microbiological processes, which are only effective when the microorganisms remain in a healthy state.
- If a biological process upset was to occur, due to a toxic shock load or c
Download: Manual for Wastewater Chlorination and Dechlorination Practices
Published by California State Water Resources Control Board
This manual was prepared to provide regulatory agencies, consulting engineers, and treatment plant operators with the urgently needed information on recommended chlorination and dechlorination practices. The principal aim of the manual is to improve wastewater disinfection and reduce residual toxicity associated with chlorination. It is expected that significant savings in chlorine w…

Accurate and reliable testing of raw, process and treated wastewater is fundamental to the efficient operation of a wastewater treatment facility.
As with many other types of industries, some form of process monitoring is required for wastewater treatment plants to ensure that the quality of the final product is maintained at the highest possible level. One of the methods used in the wastewater treatment industry to maintain a high quality effluent is…
