The work will consist of:

1.1.1. Replacement of the activated carbon at filters #1 and #2 (40 Tm wet carbon) for the production system of the potable water at Moron Air Base.

1.1.2. Extract, collect in authorized containers, transport to an authorized treatment facility and perform administrative management to existing activated carbon residue.

1.1.3. Cleaning of interior of filters prior to replacing with the new activated carbon filtering bed (12 Tm dry carbon activated).

1.1.4. Filters set up.

1.1.5. Final cleaning of installation affected by the present contract.

1.2. Special Requirements: The personnel at the Osmosis Plant shall work with the Contractor on the required operations for the opening/closing of the valves which control the functions of the filters. The Contractor shall not perform any operation on the valves which control the functioning of the system, all required operations shall be performed by Base personnel. The work will be accomplished in two phases, each phase apply for all the activities regarding one filter. The first phase will be accomplished completely before to start with the second phase.

1.3. Brand Names.

Names indicated for materials are for the purpose of establishing a standard selection only. Other manufacturers' materials are acceptable provided they conform to all specified requirements.

Names indicated for the quality of model, give the quality standard to be achieved. Other manufacturer's materials are acceptable if it is equal to the quality and function of the suggested model. All selected material is subject to the approval of Contracting Officer.

1.4. Filter Characteristics: The characteristics of the filter are as follow:

Type: FIC-2500 manufactured by STF-Filters.

Year manufactued: 2006 Number: 1555/2.

Code: ASME VIII Service Pressure: 4 BAR Design Pressure: 5 BAR Service Temperature: 20 Celsius.

Design Temperature: 40 Celsius.

Volume: 25,210 liters Area: 4.91 m² Vacuum Weight: 5,000 Kg.

1.5. Activated Carbon MG 950: Granular activated carbon to be used in the performance of this contract shall be type MG 950 from selected bituminous mineral carbon, by means of a thermal activation process. Carbon shall be subjected to successive processes of reactivation with excellent recovery of its characteristics. The utilization of the carbon in a fixed bed filter system is recommended as it permits a minimum of loss during the processes of backwash and regeneration. The MG 950 carbon contains a high proportion of pores on the low range of meso porosity, which provides high performance in the processes of the potability of surface or well water.
