Safe And Sound 2021

https://www.osha.gov/safeandsoundweek Safe + Sound Week is a nationwide event held each August that recognizes the successes of workplace health and safety programs and offers information and ideas on how to keep America’s workers safe.

In 2021, for the duration of this week, WasteWater Education 501(c)3 made our online/on demand CEU series free for general viewing with our thanks to Travis Vance and Patrick W. Dennison of Fisher Phillips LLP.

As a public service we are leaving the core presentation as open source/open access. If you would like to take this and other classes in this series for CEU or PDH Credit – please see our web site at https://wastewatereducation.org/onlineclasses.html WasteWater Education does not collect, track or share personal information for publicly available events.

There has been growing interest in integrated iron(Fe)-salts or waterworks Fe-rich sludge uses for system-wide operation, aiming to reduce the overall chemical footprint of urban water utilities.

The multiple beneficial uses of iron (either in the form of iron-salt or iron-rich sludge) in sewer system and downstream wastewater treatment plant in an integrated manner have found to achieve sulfide removal in sewers (decreasing sewer odour and corrosion), phosphorus (P) removal during wastewater treatment, hydrogen sulfide (H2S) removal during digester biogas generation, including improving the sludge settleability and dewaterability during wastewater treatment processes.

When adopting such integrated strategy of in-sewer iron-dosing, iron is reused four times during transit through the treatment chain of urban wastewater system thereby substantially reducing chemical usages. 

The project outcomes identified clear opportunities for water and wastewater utilities to collaborate, and share the benefits, providing water/wastewater services in a cost-effective manner albeit with improved environmental sustainability.

The current presentation will primarily shed light on the underlying mechanism behind some key beneficial aspects when implementing iron-dosing in integrated sewer-wastewater treatment plant.
