Mechanistic understanding of multiple beneficial aspects of iron-salts & iron-rich waterworks sludge uses in integrated urban wastewater system – Lessons learned from lab-scale, pilot, & field studies
Dr. Sohan Shrestha completed his PhD in 2020 from Advanced Water Management Centre (AWMC), School of Chemical Engineering, The University of Queensland (UQ), Brisbane, Australia. Currently, he works as researcher & water treatment operator for Arris Water Pty Ltd.

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.
EArth Day 2021
Session Three of “It’s ALL about the money, isn’t it?” will take place on April 22.
Never has it been more important to be able to predict how climate will impact community water and wastewater systems of any size!
It’s ALL about the money! Session Two now available
Session One: watershed modeling
It’s ALL about the money isn’t it?
Model. Monitor. Map. Maintain. Manage.
Tools for crunching numbers: For communities of any size.
This 8 week Symposium is an opportunity to learn from the best how to make wise, affordable and sustainable wastewater decisions for your community.
All events can be attended live or viewed later as an on-demand recording.
To view the individual sessions or register for all 8 go to

Session One: Watershed Modeling Tools is now available here.
We were busier than ever in 2020
We have been busy – and we have a new office
WasteWater Education 501(c)3 came to the close of our FY2019-20 with a healthy balance and increased participation – in both distance learning online/on demand CEU classes and WWETT sponsored public education events! Look for the publication of our Annual Report here shortly.
It is with a heavy heart we acknowledge the demand for our distance learning expertise has come at a sad cost and for the saddest of reasons – Covid19. We are honored to help but wish it wasn’t for this reason.
Since the June WWETT event discussing the innovation happening in Swedish wastewater reuse, we have hosted the following events which you can also view on our YouTube Channel.
BAHMAN SHEIKH, PhD, PE.Visiting Assistant Professor, University of California, Davis
It is with great sadness that we report that Bahman passed away peacefully shortly after recording this event. Our thoughts are with his family.
This event focuses on the experience gained in the field in California and other regions over the past several decades regarding use of recycled water for irrigation of agricultural crops.
Regulations governing use of recycled water for agriculture will be discussed comparing their stringency and effectiveness with special emphasis on microbial risks.
Chemical risks from use of recycled water for irrigation will also be discussed summarizing research findings of recent years, particularly with regard to constituents of emerging concerns, also called microconstituents.
The main conclusion to be drawn is that existing regulations are adequately protective of the health and safety of farm workers and consumers of agricultural crops grown with recycled water. The extremely low concentrations of microconstituents detected in recycled water are placed in perspective with calculated numbers of years of exposure necessary to accrue one safe daily dose of each of the constituents of concern.

What kept you awake at night a year ago has now changed – for ever.
Communities of any size, from 250 to 250K, are facing the new reality of reduced revenue, ongoing repair costs, and wildly fluctuating use patterns.
If you have an asset management system, or are wondering if now might be the time to figure out how this might work for you, come see how Los Angeles County does this in real time.
In any community, there are many employees, departments, contractors, inspectors and service personnel who all need to work together and have equal access to any piece of the data that impacts them – on demand.
Asset management is not just a data base, not just a catalog of parts and activities. At its best it mirrors the system and allows everyone, at any time, to see what’s happening – and what might be ABOUT to happen!
Hosted by t4Spatial, where the mission is simple. To get more value from your pipeline inspection data and CCTV video. That means storing, indexing, and sharing your videos in the cloud and visualizing your inspection data via embedded links so it’s more accessible, usable, and valuable. Can you to find the information you need, when you need it, and from any device, while tethering your resources together to maximize workflows?
Come find out how.

Environmental decisions are based on environmental sampling data. But how much is toomuch?!
Having the ability to quickly and clearly understand the data is important to quality decision-making.
Using web and mobile platforms facilitates the management, collection, labeling, and reporting of both environmental field data and laboratory data. SampleServe facilitates planning, sampling and the reporting for a wide range of environmental professionals and service personnel.
