2026-11-03

A . All of the demineralizers shall consist of the following trailer mounted tank units designed for 100 psig , 100 ºF , and 125 GPM maximum operating conditions shall be capable of being easily maneuvered into and out of the tight areas at the above two sites : i . Minimum of three ( 3 ) tank units each with 28 cubic feet one with strong acid cation resin and one with strong base anion resin and a third one with mix bed resin . Typically tanks are 36 " diameter x 4 '- 6 " height , 100 psi rubber lined pressure vessels . All tank modules shall have associated piping , valves , and fittings equivalent to the following : a . At vessels : PVC inlet distributor and PVC under drain distributor . b . Piping : 3 " diameter schedule 80 PVC piping with 3 " Butterfly inlet and outlet block valves . c . Connections : 3 " Male Kamlok . d . Manual air vent . 2 . One ( 1 ) accessories module complete with following controls and instrumentation : a . Self - acting pressure control valve ( PCV ) b . Automatic shut - off valve c . Totalizing Flow meter d . 10 Micron Resin Trap with ß10 Ratio of ≥ 5000 e . One ( 1 ) effluent monitor to measure conductivity from the demineralizer , interconnected with the shut - off valve to stop flow upon resin exhaustion . f . One ( 1 ) pressure gauge and sample valve assembly provided upstream on the PCV , downstream of the PCV , and downstream of the resin trap . g . Discharge check valve . 3 . The Utility also seeks proposals for skid - mounted mixed bed ion mini exchange units ( one for each site ) for the purpose of scrubbing CO2 from the deionized water in the storage tank at each site . The deionization units each shall have 30 to 35 cubic feet media volume with tank diameter of 36 to 38 inches and unit height between 78 and 84 inches for each site . The bidder shall provide a detailed description of the mini scrubbing units including the guaranteed thru put of each unit , monthly rental cost and unit exchange cost . All delivery , set up and pick up of exhausted systems shall be the responsibility of the contractor . Any additional requirements for the site support other than those listed under VMEU ’ s Responsibilities in Section VI shall be clearly defined . B . The demineralizer tank units shall be installed and interconnected in winterized trailers ( electrical power for instrumentation and heaters to be provided by VMEU ). The trailer units of 3 million and / or 10 million grain capacity would be quoted as requested in the Proposal Form . All necessary hoses and fittings connecting the trailer mounted demineralizer system to Plant ’ s city water lines and demineralizer outlet to the plant piping will be provided by the Contractor . C . The bidder shall state ( on the proposal forms ) and guarantee the minimum number of gallons of demineralized water each quoted system can produce for the worst case city water conditions of 200 micromhos or 130 mg / l , ( TDS ). The proposed system shall meet the following requirements : 1 . The continuous flow rate of the system may vary from 50 to 100 GPM for the unit ( s ) covered under normal operating conditions . 2 . The effluent water from the system shall have the silica and carbon dioxide and other contaminants removed by the process .
