Case Description
East Toba-Montrose Hydroelectric Project Montrose Case Study Coanda screens are designed to minimize maintenance in the field, which is crucial in remote location. For the East Toba-Montrose Hydroelectric Project, we designed and built reinforced screens in order to handle impact from larger debris overflowing the screen. Snow load was incorporated into design calculations for the screen sizing as well. Our unique force and debris calculations and proprietary wire type each allowed for added strength. Special studs were integrated into the design to help anchor the screen assemblies into concrete weir walls at the site. This tough, easy to install, low-maintenance screening technology can be used to simplify and implement run-of-river hydro anywhere.
Line Creek Water Treatment Plant Montrose Case Study Debris handling is expensive. Side intakes at low head dams are the most common application for raw water intakes, most of which require a significant amount of debris handling. The majority of debris handling at these sites is done by mechanically driven equipment, including: traveling screens and raking devices. These equipment options require significant maintenance costs.
A Coanda screen design was used in a recent water treatment plant installation in Georgia called Line Creek. Line Creek retrofitted an existing low head dam by installing a Coanda screen on half the structure. The system has an 18 MGD capacity and the screen panels themselves have a footprint of approximately 100 square feet. Cook Legacy used its sizing model to design an accurate screen by analyzing the flow elevations above the crest, velocities inside collections chamber, and elevations in the pump station at different flow patterns. These details have allowed the Coanda screen a smooth implementation with the entire system.
Illundo Small Hydro Montrose Case Study To determine the feasibility of producing electricity from two rivers near Ilundo, Tanzania, a group of citizens of the region partnered with Coanda Power Systems to determine the feasibility of a small hydro project. The proposed sites will employ Coanda Power Box and and a Coanda Powerhouse to maximize hydraulic potential while minimizing impacts on the environment. The project will supply the village of Ilundo with sufficient power while allowing the locals to potentially sell some of the power back to the electrical grid.
Fitzimmons Creek Hydroelectric Montrose Case Study The Fitzimmons Creek Hydroelectric project used approximately 4.25 CMS of water to generate 7-9 MW of power for use at Whistler Mountain, the site for the 2010 Winter Olympics Alpine events.
Brandywine Creek Montrose Case Study The Brandywine Creek installation has been operational since 2002. It is a small Run-of River site that served as a proof of concept for future Coanda Intakes. After some design modifications in 2004 (which are now design standards) the system has been providing clean, consistent power.
McNair Creek Montrose Case Study Mc Nair Creek was built in 2004 and has been in successful operation since installation.
