Automatic control of the local rinse water treatment facilities
Summary
On the basis of the system analysis of the operation of local rinse water treatment facilities of the steel band dip galvanizing line the structure of a process unit as a controlled object was developed. The vectors of the output coordinates of control and disturbing actions are defined It is shown that the controlled object is multi-dimensional, unsteady and has an unstable structure. The results of the study were used in designing and introducing an automatic control system of the local rinse water treatment facilities.
Key words

Indirect method of determining pollution concentrations of train track surface runoff
Summary
The classification (categorization) of the train track and railway station ballast section pollution density has been developed and approbated. Each category of train track pollution density is specified and the criteria of the space interval attribution to a pollution density category are presented. The pollution concentration of train track surface runoff as a function of the ballast section pollution density is determined.
Key words
suspended substances , oil products , surface runoff , train track , ballast section , pollution density classification , pollution density category
