DEMINERALIZED FEEDWATER TRAILERS SOW.pdf

DEMINERALIZED FEEDWATER STATEMENT OF WORK

1.0 Applicable to items: Grade “A” Feedwater is water that has been stripped of all impurities. The term

“feedwater” will be used hereafter to describe the end product meeting all requirements of the contract specification.

1.1 Capacity: The feedwater generating rigs shall be capable of processing not less than 80,000 gallons of water without regeneration when the average Total Dissolved Solids (TDS) does not exceed 300 Mg/L.

The maximum number of water treatment trailer systems in simultaneous use by the Government at any given time is ten (10). The actual quantity will vary depending on the number of ships/facilities being serviced and the criticality of these services. As such, the CLIN quantities identified herein are estimates only and are based upon historical data as well as current workload projections.

Estimated total gallons to be processed yearly are 1,920,000. This number may vary depending upon operation demands.

1.2 The rig shall be designed to operate with a fresh water inlet pressure of 25 PSIG to 100 PSIG with a maximum outlet flow rate of 200 GPM.

2.0 Freeze Protection

2.1 Freeze protection shall be provided by the contractor 365 days per year. Contractor will be responsible to ensure components of the feedwater rig are properly protected from frost or freeze.

NNSY will provide auto drip valves and/or heat trace on downstream equipment.

2.2 The Norfolk Naval Shipyard, Portsmouth, VA will provide a source of electric power and cables to hook-up freeze protection, when required.
