Experimental study and application of gels formed by nonionic polyacrylamide and phenolic resin for in-depth profile control - ScienceDirect
Moreover, these gels typically have lower thermal stability in high temperature reservoirs, resulting in over cross-linking or syneresis, and produce a failed in-depth profile control treatment. Organic cross-linking reactions involve the

Get Price- How many water treatment plants are there in Moscow?
- Alexei Babayev: There are four water treatment plants in Moscow that treat surface water and make it drinkable. The total length of the city system is about 13,000 kilometres of varied-diameter pipeline. In the city there are 11 regulatory nodes — reservoirs and pumping stations. Storage tanks are used to hold water from the treatment plants.
- How long does a water treatment plant take in Mosvodokanal?
- Moscow has four water treatment plants: Rublevskaya, Western, Northern, and Eastern. It takes eight to 12 hours to bring water from the intake to the tap in a flat. Chief Engineer of Mosvodokanal (municipal water and wastewater utility) Water Supply Department, Alexei Babayev, knows how to make water from a reservoir drinkable.
- How do water treatment plants work?
- The water treatment plants adjust the treatment mode of the water: amount of chemicals, filtration speed, the facilities undergo more frequent cleaning. Moreover, there is a plankton blooming period — mass growth of phytoplankton in the reservoirs. This usually happens in the summer when the water gets warm.
- Why did Sergei Sobyanin visit the Rublevskaya water treatment plant?
- On 13 October, Sergei Sobyanin visited the Rublevskaya water treatment plant, which has been equipped with an additional water filtration unit using the latest water purifying technology based on ozone-sorption. The most advanced technologies have made water in Moscow flats purer, more transparent, and odourless.
