Термин TDS расшифровывается как “total dissolved solids” и означает общее количество растворенных в воде частиц, другими словами — общую минерализацию в ppm (parts per million = миллионная доля), что эквивалентно 1 мг/л (миллиграмм на литр), или общему количеству растворенных в воде частиц солей на один миллион частиц воды.
Мы измеряем TDS для оценки переноса и осаждения солей с атмосферными осадками.
Как показали измерения TDS: - талая вода имеет 4 - 5 ppm - дождевая вода 20 ррm - талая вода с проезжей части 1867 ppm

At this point, however, Durov had already been working on Telegram with his brother, and further planned a mobile-first social network with an explicit focus on anti-censorship. Later in April, he told TechCrunch that he had left Russia and had “no plans to go back,” saying that the nation was currently “incompatible with internet business at the moment.” He added later that he was looking for a country that matched his libertarian ideals to base his next startup. On Feb. 27, however, he admitted from his Russian-language account that "Telegram channels are increasingly becoming a source of unverified information related to Ukrainian events." Telegram was co-founded by Pavel and Nikolai Durov, the brothers who had previously created VKontakte. VK is Russia’s equivalent of Facebook, a social network used for public and private messaging, audio and video sharing as well as online gaming. In January, SimpleWeb reported that VK was Russia’s fourth most-visited website, after Yandex, YouTube and Google’s Russian-language homepage. In 2016, Forbes’ Michael Solomon described Pavel Durov (pictured, below) as the “Mark Zuckerberg of Russia.” "Your messages about the movement of the enemy through the official chatbot … bring new trophies every day," the government agency tweeted. So, uh, whenever I hear about Telegram, it’s always in relation to something bad. What gives?
