Cooling/Heating Water System Treatment
The work compromises furnishing all labor, materials, utilities, transportation, equipment, and services to accomplish all work for this Service Contract in accordance with these drawings and specifications.
Raw water and water treated at the Reverse Osmosis plant: Perform an initial water analysis in the water treated at the reverse osmosis plant, raw water coming from the production ground water wells and water injected in the water distribution system (RO treated water blended with raw water). Study the corrosiveness of the water entering the distribution system depending on the blending ratio and provide the most beneficial ratio to avoid corrosion in the Domestic Cold and Hot Water open circuits, as well as in the closed cooling, heating and steam systems.
Cooling Systems: perform a study in order to implement a water treatment plan by conducting an initial water analysis in the cooling system water closed loops, corrosion control inhibitor addition, periodical follow up and product reposition when necessary to keep the correct product concentration at all times (see paragraph 1.2). Modify every system as necessary to install a product injection access point useful for future product reposition
Heating systems: perform a study in order to implement a water treatment plan by conducting an initial water analysis in the heating system water closed loops, corrosion control inhibitor addition, periodical follow up and product reposition when necessary to keep the correct product concentration at all times (see paragraph 1.2). Modify every system as necessary to install a product injection access point useful for future product reposition.
Steam systems: perform a study in order to implement a water treatment plan by conducting an initial water analysis in the steam system water closed/open loops, boiler product addition, periodical follow up and product reposition when necessary to keep the correct product concentration at all times. Modify the system as necessary to install a product injection access point for close steam systems (302) and also a product injection access point including permanent dosing pumps per each product to be added for open steam systems (115) (see paragraph 1.2). The dosing pump(s) installation shall be permanent (including electrical installation) for a nominal power supply of 115volts/60Hz. Dosing pump(s) shall be able to provide the required product(s) dosage for a daily steam consumption of 7m3.
