GENERAL REQUIREMENTS SUMMARY OF THE WORK

01100-1

PART 1 - GENERAL

1.1 Project Title: Pendills Creek NFH Ultraviolet Disinfection System

Pendills Creek NFH uses ultraviolet (UV) disinfection to control fish pathogens for the incoming fish production water supply. Recently an influx of sand and detritus plugged the mud valves and backed the water up into the filter building, flooding the existing UV system. The flooding event destroyed the two existing UV disinfection systems. The UV disinfection systems in the filtration building are imperative to maintaining fish health in the hatchery. This contract shall replace the damaged UV systems.

3. PRODUCTS

General: Design, Construction and Materials:

The low-pressure high intensity UV lamps are mounted in a module that is installed through the upper support flange of the vertical glassware rack assembly. Each bank of lamps is positioned vertically and perpendicular to the direction of water flow.

Each lamp module acts as a completely independent entity as it can be serviced i.e. the lamp can be removed from its sleeve for service without disrupting water flow or turning the complete system power off. Each sleeve module can also be removed from the lamp array without disrupting water flow or turning the complete system power off. Each lamp is powered by its own independent electronic ballast for greater system reliability.

All wiring to the lamp is done outside of the vertical glassware rack assembly; no wiring is exposed/submerged in water. The UV lamp field is completely shielded to contain the

UV energy from the lamp field and cannot be opened during operation. Cleaning of the unit’s sleeve assemblies is done without the use of any chemicals; each module can be easily removed one at a time and wiped down with a clean damp rag.

A. All lamp banks with welded metal components in contact with effluent will be UV stabilized polypropylene.

UV stabilized Polypropylene is robust and non-corrosive material thus suitable for aquaculture environment.

B. All wiring exposed to UV light will be rubber coated. 4. All wires connecting the lamps to the ballasts will be enclosed inside the frame of the UV lamp bank and not exposed to water.

15179 - 5 Open Channel Vertical UV Disinfection

3.1 Lamp Array Configuration:

A. The lamp array configuration will be the uniform array with all lamps staggered to each other and vertically aligned in the channel for the easy access to the lamps. Horizontal array shall not be accepted due to the increased complexity of the maintenance.

B. The system will be designed for complete immersion of the UV lamps including both electrodes and the full length of the lamp tube in the effluent.

3.2 UV Lamp bank:

The UV Lamp Bank vessel is a channel system manufactured of heavy wall PVC and HDPE plastic, which is used to direct the water to be treated through the UV Sterilizes lamp field array. The channels lamp field array will have an overall size of approximately 75-inches long x 34-inches wide with an operating water depth of 66 inches.

B. CONTROL SYSTEM OVERVIEW

The UV Sterilizer system is designed to operate automatically. The operation of the unit is managed by its microprocessor controller system, which continuously monitors and controls the system’s functions. The microprocessor controller is the brain of the system and communicates with the operator interface for complete control and monitoring of the system. The UV Sterilizer system operates using an automatic or manual dose paced control system, to maintain an adequate UV dosage for the water flow conditions while conserving power and extending lamp life. The flow pacing is accomplished by turning on groups of (7) lamp rows with a minimum of (2) rows (14) lamps being on at all times. In automatic mode the number of UV lamp rows being on (2+) is in response to manual flow input and the UVT system. Each lamp bank uses a communications control board (CCB), which monitors the lamps status. Each CCB is located inside the PSCE’s enclosure housing and communicates with the microprocessor controller via a bus network. The microprocessor controller polls each CCB in sequence to continually update the status of each lamp. The information from the CCB’s are decoded by the microprocessor controller and then checked for errors prior to being displayed on the data status screen. (See the section on controller functions for details on alarms and the types of information displayed by the data display system). This system shall also allow the Government to do manual dose pacing by manually selecting the quantity of lamps rows to be on based upon tables supplied by the UV manufacturer that indicate lamps required to achieve the minimum required UV dose at a known water flow rate and UVT displayed by the

UVT monitor.
