Treatment Guidelines

Rocky Mountain AquaTech will test your water systems on a regular basis (monthly) to monitor the progress of the treatment and to make necessary adjustments and recommendations.
Regular testing is critical to the success of the water treatment program, and we recommend that our clients perform weekly tests to monitor the system when we can’t be there...

Chilled and Hot Closed Loops must be considered as seriously as any other system in your facility. We design this treatment based on the following considerations:
- Effective January 1, 2007, Molybdate can no longer be used in systems that drain into Denver.
- Wastewater.  As such we have removed Molybdate from products subject to this EPA restriction.
- Industry standards recommend 700 ppm of Nitrite in new-construction facilities.
- In systems that were previously treated with Molybdate, we blend Nitrite at approx. 300 ppm.
- Nitrite corrosion inhibitor provide protection to carbon steel and alloys.
- Copper and copper based alloys require an azole to provide corrosion protection.
- Our Closed Loop Treatment Blends contain tolyltriazole to help reduce copper corrosion.
- We recommend adding propylene glycol to any system that requires freeze protection.

Steam Boiler Water System (Medical, Process, Humidification, etc.) is a six step process:
- Use a softener (when necessary) the remove calcium and magnesium from the make-up water.
- To the dearator, add oxygen scavenger to prevent oxygen pitting on heated boiler surfaces.
- To the feed water tank, add caustic to provide alkalinity control to the boiler water.
- To the feed water tank, add sludge conditioner to prepare the boiler water for blowdown.
- To the steam header, add return line treatment to neutralize the condensate returning to the boiler.
- Install a controller to provide automatic blowdown to maintain an efficient cycle of concentration (TDS).

Cooling Water System (Chiller, Open Condenser or Evaporative Cooling Tower) is based on three guiding principles:
- System bleed is controlled by the conductivity of the water (measure of total dissolved solids).
- Scale and Corrosion Inhibitor is fed to the system based on metered make-up.
- Dual Alternating Biocides are fed to the system to control microbiological activity
