Eco-friendly Hydropuls method
The most well-known water treatment plant in Ostrava – Nová Ves was established in 1908 and has been in operation to this day. Drinking water produced in this water treatment plant comes from underground sources and is naturally rich in minerals that are indispensable to the human organism.
Ostravské vodárny a kanalizace a.s. (OVAK) was the first company in the Czech Republic to regenerate wells using Hydropuls, a method to clean wells by means of a rapid expansion of highly compressed gas (in this case air). After last year’s trial, OVAK used this method for the second time this year, this time in two locations in a total of seven wells, which then significantly increased their output; one of them even saw a substantial increase in output by up to 85%.
From 2017, Hydropuls increased the capacity of wells by almost 26 l/s.
The main advantage over other methods is that it employs mechanical regeneration. No chemical preparations are used for the regeneration. The length of regeneration by the Hydropuls method depends mainly on the depth of the borehole and the extent of the contamination. Approximately 10-20m perforation takes about 1 day at “usual” contamination. The technology is patented in Germany and is currently being used in the Czech Republic by a specialized company.
