6 Where Does Sewage Flow?

Where Does Sewage Flow?

Posted on May 19, 2011 by team

Have you ever seriously thought where water poured out into the sink or flushed into the toilet flows? And what happens to leftover food and our waste products which disappear in pipes? Even if you haven’t, you’ve probably heard at least something of treatment facilities and maybe know that during the cleaning process silt is obtained, which is then used for producing gas!
Today we’ll visit the Kuryanovsky water treatment plant in the south of Moscow and trace the way of sewage “from pipe to pipe”. We’ll also visit a mini thermoelectric plant running on biogas produced from silt.

Many people think that water treatment plants are something unattractive and smelly. But they are wrong! The most “fragrant” is a place of “confluence” of sewage. But it’s easy to be there for a long time without feeling much discomfort. Yes, it smells there but the smell is quite bearable.

The capacity of the Kuryanovsky water treatment plant is 3.125 million cubic meters per day. It’s located in the south-east of Moscow, in the bend of the Moscow River, and collects sewage from the north-western, western, southern, south-eastern districts of Moscow and some other surrounding areas.

The world’s largest ultraviolet disinfection unit (with capacity of 3 million cubic meters per day) is currently being built here. It’s expected to be put into operation by the end of 2011.

“Technological scheme of wastewater treatment”

During the process of wastewater treatment about 18.000 cubic meters of liquid sediment is produced daily here (about 6.5 million cubic meters per year). This sediment undergoes fermentation inside special tanks at a temperature of about 53 C. As a result biogas containing about 65% of methane is obtained.

All that we flush down the toilet flows out of these pipes. 2 million (!) cubic meters per day. 365 days a year.

This is the most “stinking” place at the plant. It’s written in quotes, because, as we already said, the smell is quite bearable.

First of all, water gets into the building where the largest garbage is filtered.

All that is bigger than 10 mm is left on the lattice.

It perfectly shows how much rubbish we flush down the toilet.

After that water goes to the so-called “sand catchers”. Obtained at this stage sand can (and actually should) be used in urban construction and improvement. But… Having a constant source of this sand, the city prefers to buy “normal” sand. Which is, of course, wrong.

    Something smells here. I am sure the water somehow, someway, is used in inappropriate means. Just like the Russian Army was fed dog food in Vladivostok, somehow, quality conrol will be lacking here.

    Fantastic post.

    hey, I live right there, in Kuryanovo! this place is 10 minutes from my home!
    sometimes it really stinks.

    Our machine shop regularly makes “sewage rollers.” There are hundreds of these (of varying sizes) at some wastewater treatment plants. The wastewater enters blackish and after going through these numerous spinning metal rollers (coated with rubber) the water is completely clear, the organic matter being obliterated by the roller’s smashing action.

    We have had a treatment plant for many years, and it represents a major step forward in environmental protection. Next: lose the lead in your gasoline Russia.

    That Effluent is pretty yellow, don’t know if I’d drink it!
