INTRODUCTION

INCLINED OPEN CHANNEL UV DISINFECTION SYSTEMS

In 2001 the first inclined UV channel systems were engineered because of the industry’s dire need for a higher range of water level installations within municipal and industrial effluent applications. Since then, the design has been optimized and the latest inclined UV lamp bank design provides users with up to 30% more depth options.

This results in advanced design scalability and customization since the users can adjust not only the width but also the height of the channel UV units. For clients with an existing water treatment infrastructure, the new design helps to save additional construction costs, as inclined channels can easily be integrated into chlorine contact tanks, as well as easily replace old horizontal type open channel UV systems. Upon installation of multiple lamp banks, the users also get an extra design advantage: a seamless disinfection path with no empty spaces in-between banks – which means that the water is exposed to UV across its entire disinfection path.

The inclined channel units, as well as vertical, has a sealed top compartment where the lamps, quartz sleeves, wiping motor, and UV sensors are easily accessible without the need for any tools. This allows for quick, easy, and hygienic maintenance procedures without the need of removing the channel out of the water. Equipped with the automated ULTRAWIPER™ feature to keep quartz sleeves clean, inclined channel units require minimal annual check-up and maintenance.
