New spectrophotometers have appeared at all water intakes of the State Unitary Enterprise Vodokanal of St. Petersburg. The devices allow you to determine the quality of city water online using eight indicators in one sample.
With the help of this modern equipment, Vodokanal specialists now automatically and continuously receive processed information from smart terminals. The control takes into account the content of nitrate nitrogen, total and dissolved organic carbon, and petroleum products in water, and also monitors the turbidity and color of the water.
Such monitoring minimizes the risk of producing drinking water with reduced characteristics, including by eliminating the ingress of foreign impurities into it. In addition, its data is in demand in process control, in particular when calculating the amount of required reagents in the blocks of the water treatment system.
The high sensitivity of flow spectrophotometers, a short measurement cycle, and the ability to quickly record changes in water quality based on the “shade of the spectrum” make it possible to ensure the safety of water supplied to St. Petersburg residents to the maximum extent.
“A number of large projects are being implemented in the public utilities industry of St. Petersburg to modernize and develop water supply and sanitation systems. This includes introducing new technologies for monitoring the quality of water that flows into the homes of St. Petersburg residents, as well as tens of thousands of enterprises and socially significant facilities in the city. New devices and intelligent systems make it possible to automate the water supply process at all stages as much as possible,” said Governor Alexander Beglov.
It should be noted that over the past few years, the authorities of the Northern capital have been carrying out large-scale measures to update the city’s water supply system. Thus, a comprehensive modernization of the storm sewer system is being carried out, launched in 2019 on behalf of the governor. This helps create a comfortable urban environment and improves road safety. Currently, work is underway on Parachute Street: during the first stage of work, sewer networks and a microtunnel will be installed in the section from the intersection of Repishchev Street to Marshal Novikov Street.
An important area of work was the program to stop the discharge of untreated wastewater into the city’s reservoirs and watercourses. Today, 99.7% of household wastewater is treated, and by 2030, the entire volume of household and household wastewater will be transferred to municipal wastewater treatment plants.
Another serious task that city authorities together with environmentalists solve year-round is cleaning the rivers and canals of St. Petersburg. Thus, in the summer, by order of the Committee for Environmental Management, the Ecostroy enterprise, with the involvement of divers, examined the bottom of the Pryazhka River for explosive objects, and also cleaned the riverbed of silt and other sediments. The Moika River was also cleared of household and natural debris. In general, the 2023 plan includes the cleaning of 344 water bodies.
