**Water Sifu #29: 10 Year Reunion** Jul 28, 2022

In this “10 year anniversary” episode, I want to take the time to say thank you, answer some very common questions about the website and the best way to use the material on it, give an update on my life, and share a few other items I think you might like.

Water Treatment Chemical Feed Pumps — **Water Sifu #28: Chemicals in Water Treatment** Aug 13, 2012
**Chemicals in Water Treatment**

In this episode I answer a couple of common questions I often receive pertaining to searching for jobs in the water industry. I discuss a speech I recently gave about this podcast, and then we hop into the meat of the show covering chemicals we use in treatment. We discuss ferric chloride and alum as coagulants, lime and carbon dioxide for alkalininty, hardness, and pH control, and gas chlorine, liquid chlorine, and chloramines as disinfectants. We also discuss perchorate and, wrapping up the show, I ask you to do me a favor.

As discussed in the show, below are some chemical equations for subjects which we covered:

**Adding gas chlorine to water drops pH by formation of two acids:**
Cl₂ + H₂O = HOCL (Hypochlorous) + HCL (Hydrochloric Acid)

**Hypochlorous acid breaking into the hypochlorite ion at higher pH:**
OH (Hydroxyl) + HOCL (Hypochlorous) = H2O (Water) + OCL (Hypochlorite)

**Adding liquid chlorine to water raises pH by forming caustic soda:**
NaOCL (Sodium Hypochlorite) + H₂O = HOCL + NaOH (Sodium Hydroxide / Caustic Soda)

**The combination of hypochlorous acid and ammonia forms chloramines:**
NH₃ + HOCl = NH₂Cl + H₂O

Submersible Ultrafiltration Membranes — **Water Sifu #27: Membrane Filtration** Jul 13, 2012
Membrane Filtration

Membrane Filtration is the wave of the future in the water treatment field. This month I spend a little time talking about my new job and the last State Treatment Exam, and then get into talking about membrane filtration in depth.

Membrane plants are totally different from plant to plant, so we talk about the different types of plants first and then jump into the items they all have in common. In this show we cover the difference between pressure systems and submersible, suction systems. We discuss the difference between microfiltration, ultrafiltration, nanofiltration, and reverse osmosis. We then discuss several methods of cleaning membrane systems and judging membrane performance common to most plants… flux or flow, trans-membrane pressure, permeability, membrane integrity testing, backwashing, or CIP’s and recovery cleans.

Advanced Treatment Audio Flash Cards
(click to listen in a new window)

I’m back for three more monthly shows, starting with another audio flash cards show. This is one I initially made for myself, but decided to release because I think some of you could find it very helpful. I found it very helpful myself, many people have been asking me to do more audio flash cards shows, and it was on my hard drive, so here it is. It focuses on treatment techniques, government regulations, types of contaminants, MCL’s, and even gets a little into chemicals and chemistry. Hope you like it!

Hello and Goodbye
(click to listen in a new window)

I haven’t stopped teaching! … still going strong and still loving it! However, this episode of The Water Sifu is the last in this podcast series. With that in mind, this show is my way of saying goodbye to those who have been listening and hello to new listeners. I wrap up some topics from last week, throw in a few small rants, talk about what my plans are going forward, and sign off.

Show Update: The Montana Water Center’s free online continuing education courses, which I discuss in this show, have been removed from their website. As such, I have removed my link and my comments about the courses from my links page.

Part 4 of a 4 Part series, this episode will take a look at how fluoride programs are implemented. We will discuss the major players behind pushing fluoridation programs, how they work together, techniques used to implement fluoridation programs, and why they are successful. From the top levels of government on down to the smallest of cities, we discuss the entire process, using the Californian push as an example.

Fluoride, Safe and Effective? — **Water Sifu #8 – Fluoridation: Safe and Effective ….Really??? (part 3 of 4)** Sep 25, 2010
Fluoridation – Safe and Effective ….Really???
(click to listen in a new window)

Part 3 of 4, This episode will focus on the “safe and effective” aspects of water fluoridation. I ask the questions… “Is it safe?” and “Is it effective?” on the way to answering the ultimate question, “Is it worth it?”. Among the evidence brought out is a chart graphing the decline of dental carries in both fluoridated and non-fluoridated communities around the world and an essay titled “Why I Changed My Mind About Fluoridation“, by Dr. John Colquhoun, a previous Principal Dental Officer from New Zealand. We discuss fluoridation studies, covering information published by the CDC’s scientists, and further discuss ways that pro fluoride groups have perverted evidence to further their cause. Also discussed are the side effects of fluoridation, including accidents as well as risks of exposure to infants, citing the ADA’s own manual **(the link has since been removed since recording the podcast)** which states that infants should not drink fluoridated water. Finally, several individuals, groups, or countries which oppose water fluoridation are mentioned.

History of Water Fluoridation — **Water Sifu #7 – The History of Fluoridation (part 2 of 4)** Sep 16, 2010
Water Sifu #7: The History of Fluoridation (Part 2 of 4)
(click to listen in a new window)

The History of Fluoridation is the subject of this weeks episode. In an attempt to fill in some huge gaps in the history of fluoridation, as told by promoting groups, I delved deep into this subject. My research took me into some pretty creepy and unexpected places. From the influence of big business in early research and promotion, to the selling of fluoridation to the public, to growing trends against fluoridation, this episode is an eye-opening, must-listen-to, podcast.

Some great links to view, along with this podcast are listed below: (Unfortunately, since recording the podcast, many of the pro or neutral posts about fluoride have been removed from the government sites originally linked.)

The Fluoride Deception: This is a three part you tube video (this link will take you to part one) which explains in depth the connection between fluoridation and big business from it’s very inception.

**The following link has been removed since recording the podcast. I can no longer find any reference to water fluoridation on the National Institute of Health’s website:** Although this article conveniently leaves out any reference to ALCOA, or any mention of Gerald Cox, who was the first to actually suggest fluoridation of the drinking water supply (see History, in the CDC Manual on fluoridation: Link in show notes for part one), this is the best history statement I have found as told from a pro / neutral standpoint.

Water Fluoridation Discussion — **Water Sifu #6 – Water Fluoridation: The Greatest Thing Since Sliced Bread, or an Unnecessary Evil?** Sep 11, 2010

Water Sifu #6: Water Fluoridation Part One
(click to listen in a new window)

Water fluoridation has long been a hotly debated topic. This episode of The Water Sifu will discuss my initial thoughts about the fluoridation of drinking water, what I found when I first started looking into it that really shocked me, and how I’ve been completely pulled into researching this very intriguing topic. This was originally intended to be a one week show, but I quickly found out that a one week show is just going to be impossible to do, if I am do do this subject any justice. So, this will be the first of four shows which will chronicle my research into water fluoridation.

(click to listen in a new window)

This episode of The Water Sifu is going to talk about water distribution systems, giving you a brief overview of how the whole process works. We’re going to talk about sources of supply, and how water gets from that source to your tap. We’re also going to talk about different types of system designs, system storage, system pressure, and how water systems work in areas of different elevations.

As discussed during the show, while talking about asbestos-cement mains, I have provided a link to an EPA page concerning asbestos in drinking water here.

Conventional Water Treatment Plant — **Water Sifu #3 – Water Treatment Overview** Aug 19, 2010
Water Sifu Episode 3 – Water Treatment Overview
(click to listen in a new window)

Water Treatment is the subject of this weeks episode, with an emphasis on Conventional Treatment. We will follow water from the moment it enters the plant as it travels through pre-disinfection and into the flash mixer where coagulation occurs. From there we follow it’s path through the flocculation basins, the sedimentation basin, the filter beds, and into the clear wells where it will be ready for consumption. We will also briefly discuss direct filtration and micro filtration.

Water Distribution and Water Treatment Operator Certificates — **Water Sifu #2 – Water Treatment Operator or Distribution Operator Certification** Aug 13, 2010
Water Sifu Episode 2 – Water Treatment / Distribution Operator Certification
(click to listen in new window)

In this episode of The Water Sifu, I concentrate our discussion on Operator Certification. I will discuss why you want to get certified, how to get certified, how to keep your certification, and how to move up the certification ranks, using California as a guideline.

Even though the overall certification process is similar and the exam questions all cover the same subjects, every state can vary a little by what they call the different levels of certification and the exact requirements for certification. If you are outside of California, please look up your state on the links page of this website for the exact requirements in your state. Even if you live outside California, you will still get a good look into how the process works, which will provide a good base of knowledge.

I also discuss water treatment and distribution training courses, exam testing, continuing education requirements, and reciprocity between states.
