So, we had another incident #55 "water treatment plants". I'm writing from my phone on the train, there might be some typos, don't blame me. I want to start with the good. I was very pleased with Musovludenal. They did an analysis of all the subscriptions they have, connected local water infrastructures and administrations. I have never seen such systematic work on sewage anywhere. As a result, they have a full understanding of what, how and where their 6,000 subscribers pollute. AI is heavily used for analysis - if there is an excess of contamination indicators, AI helps determine which plant could be the source, etc. all due respect! This is what should have started with the national projects "Improving the Volga" and "Conserving Lake Baikal". First, we analyze subscriptions, analyze drains, and then we approach the projectile from a design perspective. Aha. It was good. Now in my next post I will tell you about the reality of the regions.
