Ilsur Metshin: "Kazan citizens will forever forget about smells from the treatment facilities of the “Vodokanal”

(KZN.RU, November 29, Alsu Safina). The problem with the smell, which spreads from the treatment facilities of the “Vodokanal” to nearby territories, will be solved in Kazan by the summer of 2018. Ilsur Metshin, the Mayor of Kazan, told journalists about it during the press tour today. Now the installation of protective caps, equipped with an air purification system, is carried out on biological sewage treatment facilities. According to the Mayor, after the work is completed, the Kazan citizens can forever forget about the smells from the treatment facilities.

Numerous representatives of the republican and federal media were demonstrated how the work is going on in the area where primary sedimentation tanks are located.

Andree Egorov, the director of the “Vodokanal”, showed the Mayor and journalists at the stands where a steady technological smell is formed. He recalled that last year the President of Tatarstan and the Mayor of Kazan decided to eliminate this serious problem, after which a corresponding project was developed. It provides for the overlapping of technological objects of treatment facilities with removable structures that will prevent the spread of technological odor. 25 structures are subjects to the shelter. In addition, the project provides for an air purification system.

The works on primary settling tanks have already begun. On the question of Ilsur Metshin about the schedule of works, Andrey Egorov said that there are no backlogs. Next year, all 25 buildings will be closed with caps. It should be noted that the floor panels and trusses are made of stainless steel and have a long service life.

The Mayor of Kazan noted that the water treatment facilities of the “Vodokanal” are “one of the oldest headaches of the city’s economy”. “The problem is old. Thankfully, we found a decision”, said Ilsur Metshin. “Several large meetings were held with the President of the RT. By early May 2018, we are planning to complete the work”.

The Mayor drew attention to the fact that not only residents of the Privolzhsky district feel the smell. Sometimes, it reaches the center of the city. “The facilities were different, it was all built 50 years ago”, added the Mayor. “In the remaining six months, it is necessary to carry out and complete the work and forget about smells from the treatment facilities forever”.

It is noteworthy that the solution to the problem was found in the Year of Ecology, and the project itself corresponds to eco-standards. The process has three main stages of purification: mechanical, biological, and chemical. As a result, the water returning to the Volga corresponds to all necessary sanitary and hygienic indicators.

“This is a very serious project for us. We solved all these issues without increasing the cost for the population”, marked Ilsur Metshin. The total cost is 573 million rubles.

Another problem to be solved is the sludge. The next stage of modernization will be the construction of a shop for thermomechanical processing of the sludge, which is formed during cleaning. Thanks to the new technology, the sludge fields will go to the past.

“The project documentation has been prepared, it will be examined in December”, said the Mayor. “We hope to leave the sludge fields behind before the end of 2019”.

For today, about 300 tons of sludge is produced every day. The new shop is designed with a capacity of 400 tons.

Marat Salakhov, the first deputy director of the “Vodokanal”, told reporters how the process of sludge dewatering and exporting to sludge fields is being carried out.

The mechanical dewatering of the sludge is structurally a cascade of filter presses. In the existing shop, the sludge is dewatered to 75% moisture.

The director of the “Vodokanal” said about the fate of the existing sludge fields that “the preliminary work is carrying out on the choice of technology, pre-design work”.

I. Metshin called the SPS “Zarechnaya” the third important task that faced the city authorities. “You are familiar with this problem, it is already in the final stage. We will open capacities for the entire district, and we have large construction sites there”, he noted.

“It is three such huge problems, invisible to the city dweller. The solution will ensure the reliability of the “Vodokanal's” operation and will enable construction companies to invest in a large construction of micro-districts and complexes”, concluded the Mayor.
