Ecological Systems and Devices Annotation << Back COMPLEX WATER TREATMENT IN THE ECOLOGICAL CALS-SYSTEM OF WATER MANAGEMENT OF THE LOW-TONNAGE CHEMISTRY ENTERPRISE V.E. Trokhin, M.V. Butakova, O.V. Guseva, A.M. Bessarabov, A.A. Klevcov The systematization of water resources management tasks at hierarchy levels is proposed: country, industry, enterprise. An ecological system of water management has been developed for one of the leading enterprises of low-tonnage chemistry, JSC "ECOS-1". The development was carried out on the basis of a promising computer support system – CALS-technology. For the three main stages of the system (circulating water supply, desalinated water production, steam generation and condensate treatment), the tasks of water treatment (combating salt deposition, corrosion and biological fouling) with the use of reagents produced by JSC "ECOS-1" were considered and solved. Keywords: ecological system, low-tonnage chemistry, water management, water treatment, technological regulations, computeraided design, CALS technology. DOI: 10.25791/esip.9.2023.1396 Pp. 28-36.
