Improving the quality of irrigation water by vacuum treatment

Abstract

The first stage of research of the water purification plant was carried out in laboratory conditions on a hydraulic model at the Department of Water Supply of the Volga State University, the second stage of tests for purification and activation of water was carried out at the experimental production site of the Volga State University “Innovative Village” before sowing tomatoes in the ground, on a plant with a capacity of 10 m3/ day. The second stage included the work performed in the following sequence: first, they achieved stable operation of the water purification unit by vacuum-ejection method, then they achieved stable operation of the water activation unit using a vacuum activator. The final tests were carried out at the start of both installations. The installations worked in semi-automatic mode. It should be noted that the vacuumejection unit includes a vacuum-ejection oxidizer and a semi-automatic sand filter, working as a single unit.
