Method for processing in-process monitoring results to improve drinking water quality and safety (experience of SUE «Vodokanal of St. Petersburg»)

Summary

The paper concentrates on the experience of SUE «Vodokanal of St. Petersburg» with regard to the development and introduction of the method of processing and storing the data of in-process monitoring drinking water quality and safety. In accordance with Russian Government Resolution No. 10 of January 6, 2015, water utility operators are responsible for conducting in-process quality control of drinking water at the source, after water treatment, and in the water distribution network. SUE «Vodokanal of St. Petersburg» provides for the in-process water quality control at 396 monitoring points. Considering the requirements of the Russian legislation, the amount of laboratory tests is approximately 16,000 per month. Processing and analyzing such a volume of information received monthly is a labor-intensive and resource-consuming process. Automating the process of processing laboratory test results provides for reducing the human factor effect in data transfer and processing; automatic checking deviations from acceptable limits, and minimizing errors in calculations and result interpretation.

Experience in upgrading water treatment facilities under limited budget: the practice of retrofitting a dynamic water clarification technology

Summary

The experience in upgrading water treatment facilities in the town of Malaia Vishera, Novgorod Region is presented. The water supply source, the Malaia Vishera River, is characterized by high color (180–400 degrees), high permanganate index (18–36 mg/dm³), and high iron oxide concentrations (0.8–1.7 mg/dm³). The treatment facilities were built and commissioned in 1970. In accordance with CP 31.13330.2021, a multi-stage treatment flow scheme was required. Due to the limited funds for the upgrade of the facilities, it was decided to use a single-stage water treatment flow scheme using Diclar dynamic clarification technology (Mirrico Group of Companies). The results of five-year operation of the treatment facilities using this technology are presented.

Опыт компании «Полимерконструкция» по реализации биохимических технологий очистки подземных вод

Аннотация

Ключевая особенность биохимических процессов, протекающих на поверхности фильтрующей и (или) контактной загрузки внутри фильтров и описанных еще в конце XIX века академиком С. Н. Виноградским, заключается в их естественном происхождении. В той или иной степени эти процессы возникают практически на всех этапах водоподготовки, особенно при использовании аэрационных методов удаления таких загрязнений, как железо и марганец. Задача специалистов заключается в том, чтобы создать условия для эффективного протекания этих естественных процессов и использовать их в целях водоподготовки.

Resent research on the effect of surfactants on oxygen transfer
in aeration systems

Summary

A review of the recent global research on the effect of surfactants on oxygen transfer in wastewater aeration systems is presented. The data on the mechanisms of surfactants affecting the volumetric mass transfer coefficient kLa, including a 20–70% reduction in the liquid phase mass transfer coefficient kL, the formation of diffusion barriers at the interface, and changes in bubble size and interfacial surface area are systematized. It is shown that the alpha factor for fine-bubble aerators in the process of municipal wastewater treatment ranges from 0.4 to 0.8 and significantly depends on the surfactant concentration. The differences in the effects of anionic, cationic, nonionic, and amphoteric surfactants, as well as biosurfactants, are examined. Outsize effects are discussed, including possible increasing of oxygen transfer efficiency in the presence of surfactants under certain conditions. Practical recommendations for designing aeration systems with account of the surfactant concentration in wastewater are formulated; and the key areas for further research are identified.

The technology of wastewater treatment of PVC floor tile production

Summary

The results of studying the treatment of wastewater generated during the production of polyvinyl chloride tiles that contains thermal decomposition products of the starting materials. Experiments were conducted on wastewater processing with oxidizing agents – Longafor and Khloriteks containing compounds of tri- and dichloroisocyanuric acid, respectively. It was found that the treatment efficiency, based on COD, for both chemicals was 65–75%. Exposure of a wastewater sample after chemical treatment and filtration for 72 hours improves the treatment efficiency to 85–90%. Conceptual wastewater treatment schemes at the intermittent and continuous inflow, as well as with water recycling, were developed.

Multi-agent intellectual monitoring and control of wastewater disposal with operational analysis of the optical characteristics of aqueous solutions

Summary

The information and measurement support for the operation control of water supply and wastewater disposal systems was analyzed. A conclusion was drawn regarding the feasibility of a comprehensive solution to interrelated problems, i. e. on-line monitoring of aqueous solution quality indicators and on-line process efficiency analysis. Within this framework, a mobile automated unit for simultaneous measurement of absorption and scattering spectra was developed and tested as a means of on-line receiving data on wastewater parameters. The results of the spectroscopic study confirmed the potential of non-contact optical approaches for estimating wastewater quality, since the spectral characteristics of the studied model samples depended significantly on their composition. A multifunctional and multipack approach to creating an intellectual multi-agent system with a unified semantic information space and hierarchical knowledge organization based on OSTIS was substantiated. Integrating POTENTIAL software (adaptive control of the process parameters of wastewater treatment facilities), the Intellectual Resource Analytics Module (monitoring wastewater disposal parameters), and a complex for analyzing the optical characteristics of aqueous solutions into digital platforms for water and wastewater utilities, using multi-agent approaches was proposed. This will significantly improve the efficient automation of municipal wastewater disposal and treatment processes.

Water security and the environment. The Chinese way

Summary

In modern conditions of socio-economic development, China is facing an acute shortage of water resources. The level of water availability in the country is low and unevenly distributed regionally and seasonally. The solution to water security problems in China is mainly associated with hydraulic engineering megaprojects, such as the construction of the Three Gorges dam on the Yangtze River and South-to-North Water Diversion Project involving the transfer of river water through a canal system from the south to the north of the country. The scale of the projects determines the corresponding impact on the natural environment with difficult to predict consequences.

Improving the energy efficiency of the blowing ventilation system by utilizing the heat of the compressor station of a hydro cracker

Summary

Hydrocracker compressor equipment generates up to 35–40% of the low-grade heat consumed; however, irretrievably lost through the cooling systems. The objective of this study was to analyze the efficiency of utilizing this heat for the needs of the blowing ventilation system of an oil refinery production building. The heat balance was calculated for the compressor station, and the available thermal capacity (560 kW) was determined based on the equipment specifications. A hydraulic circuit with an intermediate coolant (water, 70/50°C temperature chart) was proposed. For a facility (in the climatic conditions of the central region of Russia) with three compressors (one for the circulating gas, two for the makeup, and one for the backup) and a 60,000 m3/h air handling unit, the recovery was found to cover 63.3% of the heat load during extreme cold periods and completely replace the external heat source at temperatures above –3.1°C. The system operates only during the heating season (5,136 hours/year). The annual thermal energy savings amount to 1,872 Gcal, resulting in savings of over 5.05 million rubles with a capital investment payback period of approximately 2.5 years. The proposed solution is economically feasible and can be recommended for the application at oil refining facilities.
