GTI Covers Selected for Sewage Treatment Plant Improvement Project

Geomembrane Technologies Inc. (GTI) has been awarded a cover project in New York, USA.

GTI will design, fabricate, and deliver two suspended covers as part of a sewage treatment plant improvement project. One portion of the project involves converting two secondary clarifiers into gravity thickeners. GTI’s suspended covers will be mounted on the 26 ft (8 m) diameter steel clarifiers to control odors and better regulate temperature within the tanks.

Odor had become a concern at the sewage treatment plant, especially in the summer months. Winter also presented challenges because there were concerns of tank contents freezing. GTI’s covers will help address both of these issues.

Access is often an important consideration when designing tank covers. GTI was able to provide a simple means of detaching the cover at the clarifier bridge and an integral tube to roll the cover to the far side of the tank. Peripheral attachment/detachment is also possible with this design.

The project is expected to be completed in summer 2017.
