history is the continuous improvement we do it through the tight cooperation with more than 700 customers. "EKOTON company is the largest equipment manufacturer and supplier of modern technological solutions in the field of wastewater treatment and sludge dewatering in Russia. For 16 years of activity the company has implemented more than 1000 successful reconstruction and modernization projects for wastewater treatment plants of municipal and industrial enterprises. Complex projects include technology developing, designing, The excellent team of experts has been formed during the company's...

In order to facilitate maintenance of the mechanical treatment stage, to minimize the influence of "human factor" and to provide energy-saving, it is appropriate to implement the complex of equipment including screens, conveyor and compacting press set to work together in automatic mode. Automated complex Over time, the company supplied more than 600 sewer screens, most of which were a part of the automated systems with conveyors Various schemes of screen operation automation are possible: by operating time, by wastewater level difference in the channel before and after the screen, by the...

Bar screens are intended for extraction of large and medium-sized solids from wastewater and recommended for using as a preliminary mechanical treatment at sewage pump stations. The possibility of reducing clear openings range down to 5 mm allows to use the bar screens for the fine screening at wastewater treatment The bar screen is completely manufactured of stainless steel. The ways of movement of chains are protected from abrasion by a wear-resistant Screening element is assembled of bars with a drop-shaped section, thus reducing the flow resistance by 15-30% compared with screens formed...

Step screens are intended for extraction of medium and fine-sized solids from the wastewater and recommended for fine screening of municipal and industrial wastewaters. The design of the solid removal profile does not allow the winding of the waste, therefore demonstrating the excellent quality of work with the wastewater containing rags, wool and other similar contaminants. Stepwise principle of operation provides forming of a waste layer on the work surface of the screen, hence retaining contaminations larger than 3 mm on a filtration profile with 5 mm spacing between step lamellas. The...

Drum screen Brush type RMB-Brush The screen is applied at the municipal and industrial wastewater treatment plants with a maximum flow rate 150 m3/h. It is mounted directly on the pipe and ensures extraction of solids larger than 0,8 mm. The drum screen is completely manufactured of stainless steel. The screenings holding sieve is cleaned by rotating brushes inside the drum. Optional it is possible an additional flushing of the sieve with pressured wash water and heating of internal space The screen's top is covered by a lid, therefore preventing spattering and spread of odors, also...

Grinder screens are intended for grinding of big and average wastes, which came with sewage flow to sewage pumping stations. Installation of the grinders at the sewage pumping stations is the most effective way to protect pumps and completely solves the problem of removal and disposal of retained In-channel grinders are made entirely of stainless steel and the grinder-mills themselves are made of high strength steel AISI440A. For prevention of large flat waste skipping which is observed in operation of the similar equipment, shafts rotate towards each other with different Automatic reverse...

The screw conveyor is used for solid screenings or dewatered sludge (cake) transportation in horizontal or inclined plane on distance to 30 m The conveyor is manufactured completely of stainless steel, and the operating spiral is made of special wear-proof steel. For prevention of wearing by a spiral the bottom of case is protected by the replaceable wear-proof polymeric insert. Use of a spiral for solids moving to the conveyor allows lowering loading on a drive in comparison with axial screw gears. The shut case of the conveyor prevents distribution of odors. The dump of solids in the...

Combined module Max. flow capacity, cu.m/hr 200-13300 Diameter of retained particles Nonstandard equipment production is available on request Tangential grit chambers PT Max. flow capacity, cu.m/hr 50,100 Feed rate of waste water, m/s 0,6-0,8 Diameter of retained particles Mixing unit drive power, kW 0,18 Conveyor drive power, kW 2,2 Nonstandard equipment production is available on request Grit chambers Combined module: Screen and compact Grit chamber RPK The unit is a compact set of equipment for extraction from the wastewater of medium and fine- sized screenings, sand and fat-like...

Scraper complexes IRPO Scrapers are used for sludge removing from the bottom of radial clarifiers of various diameters. While designing the constructors' efforts were directed to maximal reliability enhancement, costs decreasing and sludge scraper complex serviceability ensuring. The sludge scraper bottom construction enables to remove the sludge on the whole of settler bottom qualitative, because of scrapers on the sludge scraper gyration wings which changing its length and bend approaching to the central sink. For optimal sludge collecting in concrete operation conditions the scrapers...

Dissolved air flotation units FT Treatment efficiency characteristics Main technical characteristics: Nonstandard equipment production is available on request DAF-units are used for the removal from wastewater of fine-sized sparingly soluble particles as fat, weighed and surfactant species at pulp and paper plant enterprises, food and oil-refining industry, small sewage treatment facilities and also for sludge compound thickening at utility plants treatment facilities. The special shape of unit chamber ensures sufficient time for the occurrence of the flotation process (time for flotation...
