Influence of changes in the Volga river water expenditure on water hardness and alkalinity increase in Kuibyshev refinery river intake

[摘要] The chemical control department of the Kuibyshev refinery (known as KNPZ) registers a systematic increase in river water hardness and alkalinity. The increase of these values changes the reagent softening mode of clearing agents with weighted sediments. It is required to carry out a constant analysis of water alkalinity before reagent softening. The researchers collected data of average monthly values of the Volga-river water samples from Samara Hydroelectric Station, the Samara-river water samples from the Bezymyanka heat power-station, the Volga-river water samples from Kuibyshev refinery as well as hourly water samples from the same stations and compared it with the data on average daily Volga-river water discharge from Zhiguly hydroelectric power station, obtained in 2016, from July till October. The analysis of the data showed that changes of the Volga-river water discharge had no effect on the increase of water alkalinity and hardness of the KNPZ river intake.
