1-Pretreatment & Filtration

[@dailylivingwithwater4540]

Some good nuggets in this training segment. But, here's where confusion can ensue. At 21:40, the topic of water softeners is covered for this portion of the pretreatment considerations. The Powerpoint slide identifies the chemistry of hard water as calcium, manganese, and iron when the list should be calcium, magnesium, and iron. The instructor correctly identifies verbally to the class the chemistry is magnesium. I'm not in the market for commercial boiler applications, but a distributor of water treatment chemicals. Before making a global commitment to broadcast this error, the presenter should have had a chemical engineer sign off on the slides. But I get it. People make mistakes. (They mentioned in the 6-hour stream class that they have beer available in the fridge after class.) I'm sure I've misused chemistry names by replacing a similarly pronounced name of an element over the years. Here's hoping my comment will bring attention to the presenter about this slide. All in all, I gained a deeper understanding of the scale commercial boilers require filtration and pretreatment and the solutions available to backwash the sediment out of water in a way that conserves water by significantly reducing it in the backwash treatment. More coffee, less beer, unless it's (root beer or ginger ale) within 50 feet of the Powerpoint content creator. 😉

Will you explain blowdown? What are different types of blowdown (boiler blowdown, RODI blowdown)?
