Description

This Prior Information Notice (PIN) relates to a project to establish an agreement for the Supply, Delivery, Installation & Maintenance of Side Stream Filtration Units (UOS-22506-2021) at the University of Strathclyde. The University of Strathclyde has recently installed a district heating network, that includes a number of side stream filtration units to maintain a high standard water quality. The University also has some units installed in CHW systems, however, it is anticipated more of these units will need to be procured. The University invites companies with a product that can fulfill all parts of the following specification, including experience of maintaining that same product, to express an interest in this Prior Information Notice (PIN); - Filtration to less than 5 microns; - pH Control to maintain pH 9.5-10.5; - inhibits corrosion maintaining less than 1.0mg/l; - that removes air/microbubbles; - that restricts bacterial growth; - has BMS connection; - requires no dosing pots or injection pumps negating the need to carry drums of chemicals through buildings; - has no dosing pots to prevent the need to store chemicals on site; - has a small footprint; - uses back wash that can be connected to a drain or discharge into a gulley; - has a glycol recuperator to recover glycol from cooling systems. The recuperator will automatically pump the glycol back into the cooling system; and - requires no consumables items such as filters.
