The automated filters of the FK series were developed for the conditions of extremely polluted water of the CGOK.
After several months of operation of the new filter size of the FK filter in very contaminated draysene water at the Customer, the specialists of Oceananashenergo came to the conclusion that it is necessary to refine the design of the filter under the new operating conditions.
The typical design of the FC filter was not designed for constant large inflows of Draisena shells into the filter. There were cases of slipping through the coarse screen of large fragments of contaminants, clogging of filter elements and the automatic protection against jamming of the drive.
The specialists of Oceananashenergo analyzed the current situation, quickly finalized the design documentation for the filters, manufactured additional elements and carried out refinement and retrofitting of the filters at the operating site for severe operating conditions.
Were finalized: the installation and fit of the coarse grate to the housing, the seals of the lower bearing, the nozzle of the drain line and a number of other elements.
After improvements, the FK filters are again in normal operation, and perfectly cope with heavily contaminated water..
Automated filters FK.A-1530 are mounted on pipelines of pumping stations of PJSC ArcelorMittal Kryvyi Rih.
Two automated filters ÔÊ.À-1530 are mounted on supply pipelines of technical water to QTB and QTS pumping stations of PJSC ArcelorMittal Kryvyi Rih. Specialists of Oceananashenergo carried out installation supervision and adjustment of filters for specific filter application conditions.
Filters are currently in operation, perfectly coping with their tasks. There are no comments on the operation of filters from service personnel.

Automated filters FK.A-1530 and FK.A-1530 are mounted on the pipelines SPC-2 of PJSC ArcelorMittal Kryvyi Rih.
One automated filter FK.A-1530 and two automated filters FK.A-680 are mounted on a supply pipe of process water for cooling the beams of the furnace of small-sized mill N4 SPTs-2 of PJSC ArcelorMittal Kryvyi Rih. Specialists of OE carried out installation supervision and adjustment of filters for specific filter application conditions.
Filters are currently in operation, perfectly coping with their tasks. There are no comments on the operation of filters from service personnel.
A collective monograph has been published, a section of which is devoted to automated filters for industrial water.
Annotation. Energy conservation in industry is directly related to the quality of water used in technical installations. One of the means of purifying process water from mechanical impurities is strainers. However, despite the variety of existing automated filters, analysis shows that not all water treatment links are provided with automatic filters that meet the relevant requirements.
The subject of the study is the design parameters of mesh industrial mechanical filters, including special conditions for their use.
The purpose of the work is to develop fundamentally new technical solutions for industrial mesh mechanical filters, including special conditions for their use.
Research methods: identifying weaknesses in the characteristics of water treatment facilities by analyzing its individual links, developing the main technical requirements for improving or creating new filters for these links, developing fundamentally new technical solutions that meet the developed requirements, developing methods for calculating the basic elements of new filters.
The main conclusions of the work: establish specific links of water treatment systems, industrial plants, for which there are no optimal solutions for the mesh filter, developed the technical requirements for such a new filter design, carried out theoretical study and developed the design parameters of the calculation methodology of basic elements of the new filters.

February 28, 2020 5 automated filters ÔÊ.À-680 and ÔÊ.À-1530 were manufactured and delivered to PJSC ArcelorMittal Kryvyi Rih.
Filters are manufactured under an agreement with PJSC ArcelorMittal Kryvyi Rih.
Filters are designed to protect end consumers of process water from solid large contaminants.
Filters were manufactured in difficult conditions of lack of deposit money from the customer, in an extremely short time.
Such conditions demanded that our experts maximize the stress of forces and capabilities, radically reorganize the technological processes of manufacturing and assembling the filters.
Work on the production of this order made it possible to gain valuable production and organizational experience.
February 2020
Our experts conducted scheduled maintenance of the filter FÊ.A-1530 installed at the Central Processing Plant in 2019..
As a result of filter maintenance, the reasons for the accumulation of organic contaminants (Draisen shell) were established. Technical and organizational measures are proposed to prevent such isolated cases..
The accumulation of a large amount of contaminants inside the filter and on the filter elements with large rocky single fragments up to 50 mm across did not lead to damage to the filter and its elements, which confirms the correct filter design.
After servicing the filter and taking measures, the filter is again in automatic operation.
