Wastewater Treatment, Reagent Implementation, and Corrosion Problem Solving: Summarizing the Water Treatment Conference

«Roshimreaktiv», together with Association members GC «EKOS-1» and «SPF «Travers» LLC, traditionally acted as organizers of the XI Scientific and Practical Conference «Modern Technologies of Water Treatment and Protection of Equipment from Corrosion and Scale Formation».
On October 21, nearly 80 listeners and speakers from over 40 companies and scientific institutions gathered at TGC «Vega». Participants included:

• «Krismas +» CJSC, a member of the «Roshimreaktiv» Association;

• Russian Water Supply and Sanitation Association;

• NP «Russian Heat Supply»;

• Department of Heat Power Engineering, National Research University «Moscow Power Engineering Institute»;

• National Research University «Moscow State University of Civil Engineering»;

• «Asterion» LLC;

• D. Mendeleev University of Chemical Technology of Russia;

• «Ion Exchange Technologies» JSC; and others.

The conference was opened by Vladimir Vasilyevich Antonov, President of the «Roshimreaktiv» Association. Afterwards, Georgy Alexandrovich Sambursky, Chairman of the Expert-Technological Council of the Russian Water Supply and Sanitation Association, presented a report on «Methodological Activities in the Field of Water Supply and Sanitation». A welcoming speech and a report on problems in the heat supply industry were delivered by Vitaly Alexandrovich Grachev, Vice President of NP «Russian Heat Supply».

Sergey Prorekhin, Acting Head of the Water Treatment Department at NPF «Travers», GC «EKOS-1», spoke about the experience of implementing AMINAT reagents for organizing the water-chemical regime of a CCGT-TPP.

«We found that the dosing of AMINAT reagents corresponded to the established regime charts across all technological systems of the station. The integrated approach to reagent introduction ensured an improvement in the operational characteristics of the equipment, minimized the risk of emergency situations caused by corrosion and deposit formation, and also contributed to achieving an economic effect by replacing some imported reagents with domestic analogues while maintaining comparable specific consumption rates.»

Konstantin Ivanovich Popov, Professor, Head of the Department of Applied Technologies at «Low-Tonnage Chemistry» SC JSC, GC «EKOS-1», delivered a report on «Main Misconceptions Regarding the Mechanisms of Inorganic Scale Formation Initiation, the Mechanisms of Action of Inhibitors of This Process, and Methods of Slowing Down Salt Deposition». The colleague dispelled myths about the chelate effect, electrostatic effect, and crystal deformation of deposits.

At the end of his report, Konstantin Ivanovich concluded: «The main problem is that due to various misconceptions, we know about the nature of nano-impurities not much more than about dark matter in astrophysics. We are at the beginning of a difficult but correct path.»

Maria Trukhina, Head of the Laboratory of Innovative Technologies at «Low-Tonnage Chemistry» SC JSC, GC «EKOS-1», spoke about the features of applying scale inhibitors in recirculating water systems using the new inhibitor AMETEK AP-2 as an example.

«AMETEK AP-2 has a number of advantages for recirculating water systems. We are talking about improving the efficiency of heat transfer processes and reducing equipment cleaning costs. Furthermore, the chances of emergency situations in the system are reduced, and productivity, on the contrary, increases.»

Alexey Germanovich Pervov, Professor at the Department of Water Supply and Sanitation of the National Research University «MGSU», in a short lecture, outlined new solutions for creating membrane water treatment systems without the use of reagents. The use of multi-stage schemes with nanofiltration membranes with low salt selectivity helped create technologies that reduce operating costs (for scale inhibitors and cleaning reagents) and concentrate disposal costs. This allows preventing the formation of calcium carbonate in membrane units, regulating the ionic composition of purified water and concentrate, and reducing the volume of concentrate.

A report on the treatment of wastewater with high MEA (monoethanolamine) content was presented by Eleonora Volkova, Process Engineer at «Ion Exchange Technologies» JSC. The expert explained that to treat industrial wastewater containing MEA to the maximum permissible concentration for drinking and cultural-domestic water, it is necessary to ensure a reagent contact time of up to 4 hours and maintain the pH range required for the Fenton reaction to proceed. It is also necessary to treat wastewater without its prolonged equalization, as monoethanolamine can form complex complexes.

At the end of the event, Alla Bogacheva, Lead Methodologist at «Krismas+» CJSC, spoke. Her report was dedicated to the characteristics of ready-made solutions for water-chemical control and the use of portable equipment.

The water treatment conference was successful and demonstrated the high level of professionalism of the participants. The discussion of the main topics made it possible to identify key trends and problems in the modern water treatment industry.

Conference participants noted the significant development of water purification technologies and concluded that the choice of reagent depends on the specific operating conditions of the equipment and the quality of the source water. Innovative solutions aimed at improving the energy efficiency of water treatment processes were presented. The importance of regular monitoring and analysis of water composition for process optimization was emphasized.

Thus, the conference became an important platform for exchanging experiences and identifying promising directions for the development of water treatment. Its results will contribute to the further improvement of technologies and increased environmental safety in industry.

The «Roshimreaktiv» Association thanks all participants of the event and looks forward to seeing you at the next conference in 2027!
