The contract type will be firm fixed priced. The requirement is for the manufacture and delivery of a complete packaged continuous microfiltration water treatment system. The prospective contractor is responsible to provide the microfiltration unit as well as the associated electrical controls, operator interface, piping, tubing, air compressors, air receiving, backwash, clean in place, and other tanks, and appurtenances needed for a functional system. The prospective contractor shall furnish this microfiltration treatment system as described below: The core component of the filtration system must be microporous, maximum nominal pore size of 0.2 microns, hollow fiber, which forms the filtration membrane. During normal operation of the system the water must pass from the outside of the membrane to the inside and exit the hollow membrane. The microorganisms and suspended solids are to be collected on the outside surface of the filter. As filtration occurs a periodic backwash is required. The unit shall utilize a gas backwash system to inject air into the center of the fiber, and breaking up the accumulated solids from the membrane surface to they can be flushed away. The system must utilize raw water in the backwash cycle. Filtrate water is not to be used in the backwash process. The units must automatically perform periodic membrane integrity diagnostics to assure that none of the fibers have ruptured, or if they have, to help locate the problems. The system must allow the membranes to be periodically chemically cleaned to remove iron or hardness scaling. Through the use of a Programmable Logic Controller (PLC), the systems can be left unattended with only periodic, or remote, monitoring and data logging required. The microfiltration package treatment plant shall be hydraulically capable of treating not less than 425,000 gallons of water per day at a water temperature of 35 F, and not less than 630,000 gallons of water per day at a water temperature of 68 F. The membrane system shall be capable of treating a influent surface water with turbidity of 500 nephelometric turbidity units (NTU) to a continuous effluent turbidity of less than 0.10 NTU, without undue hindrance of the plant's hydraulic capabilities, and with the only pretreatment to be a 500 micron screen. The microfiltration shall be capable of not less than 3.0 log removal of Giardia and Cryptosporidium from a surface water source. The microfiltration unit shall come as a complete system with the components to include, but not limited to, the following: Microfiltration unit, 500 micron self-cleaning prescreen with controls, Supervisory PLC and control system with operator interface, interconnecting piping and tubing within the unit, compressed air supply system, including compressors, receiver tank and controls, accessories to include pneumatic wrench for module removal, sonic analyzer and testing tube for failed filament identification, backwash system including tank, clean-in-place system with heater, pump, storage tank, and chemicals, five (5) copies of the operation and maintenance manuals shall be included. Individual membrane modules shall be accessible for maintenance and replacement without shutting down the overall array. Each membrane module shall consist of a membrane bundle enclosed in casing. Membrane material shall be capable of withstanding nominal operating pressure of up to 50 psig. Normal operating differential pressure across the membrane shall not exceed 30 psi. Membrane module blocks are to be fitted to a frame and connected with necessary piping and valving as well as electrical and pneumatic controls. The gas injection system shall be such that it insures that lubricating oils in the air compressors are not present in the air injected in the filter membrane. The Contractor shall include with their proposal a schematic drawing of the systems layout and three (3) copies of the manufactures literature describing the system. Shipping and Delivery: The Contractor shall manufacture, build test, and ship the complete microfiltration system within one-hundred eighty (180) days of contract award.
