Ultraviolet Disinfection Water Level Control Engineered Flap Gate Counter Balanced Gate. UV lamps need to be submerged regardless of the flow. At zero flow conditions, the level control gate needs to hold the water level. An engineered gate allows this to happen. Finger weirs can take up too much room and simple weighted gates are problematic.

For non potable applications, PVC UV systems are designed for small flow wastewater or clean water aquatics. Due to the PVC chamber, water is not suitable for drinking. Unit comes complete with all necessary components. Ultraviolet Disinfection UV for ponds, pools, wastewater.

UV System ballasts for amalgam lamps operating over 13 years. UV amalgam lamp disinfection.

Open channel wastewater UV disinfection systems require level control. An engineered flap gate or engineered counter balanced gate is often selected for its small footprint and low headloss. Typically, level control finger weirs are used. If there is no space, the level control flap gate can be used in horizontal and vertical channels.

This is a basic video showing some of the preventive steps you need to take when servicing UV systems. It shows horizontal open channel service and Teflon FEP tube style cleaning. 2 1/2 minutes. Meant to help visually understand.

UV lamps need to be submerged regardless of flow. Open channel systems require UV lamps to remain submerged regardless of flow. Finger and serpentine Weirs are used to control the upstream water level and allow water to flow over its top - crest. UV lamp’s electrodes need to be immersed to provide optimum output. Lamps that burn in the air reduce life, damage components, and cause quartz foulin...
