Step screen

for wastewater treatment

Ekoton Catenary Screen is a reliable solution for mechanical cleaning at sewage treatment plants, pumping stations and water-intake facilities. The screens protect the equipment in the many different stages of wastewater treatment by removing the large objects and other items that can cause deterioration of the equipment or cause accidents. It even handles large debris in large waste streams. Features and benefits of Ekoton Catenary Screens - A distinct feature of the catenary screen is its special design, i.e. the “support chain”. This innovative solution allows the chain with only one fixed axis of rotation to work both as a loadbearing and supporting structure for the rakes. - The “support chain” design lets avoiding jamming of the entire mechanism, which can adapt to the dimensions of the large waste that shall be removed. - The lamellar chain of the catenary screen significantly exceeds other chains traditionally used in rake screens in terms of reliability and safety margin. - The web is made of a drop-shaped profile or a reinforced rectangular profile of stainless steel. - The use of a drop-shaped profile is due to its high hydrodynamic characteristics: this ensures a high throughput of the screen even with small spacing. - The control system of the catenary screen is automated by time or by the level of drains in the channel. - The screen drive: high-reliability worm gear motor from one of the world leaders, NORD Drive Systems. - Engineering solutions used in the design of the catenary screen do not require complex operations for its maintenance or replacement of operational elements. - The screen does not stop when large amounts of debris enter into it.
