Watts Scale Control Technology

Fort Bend, Independent School District

Overcomes Destruction of Equipment from Scale

Armstrong ElementaryFormerly Quail Valley ElementaryStafford, TXJuly 17, 2008

Problem - Defined

For years the district used the standard, 80-year old technology, salt-based water softeners to prevent scale.

Softeners increased equipment costs for the district.

Increasing maintenance, salt storage costs, and the expense of wasted water from backwashing and regenerating.

Salt-based systems became prohibitively expensive.

Control valves on Softeners required maintenance contracts and monitoring

Salt storage required

Special storage facility (due to the corrosive properties of out gassing)

Recurring monthly expense

Labor to handle storage and fill brine tanks

Problem—Created a Chain Reaction

Use of Water Softener Excluded by Independent School District

(ISD) At Armstrong Elementary.

Excessive Scale Issues in Under 1 Year

Damage to Steamers, Water Heaters and Mixing Valves

In-Line Point-Of-Use Scale Inhibitors Required Monitoring & Servicing at Great Expense

Softener

Facilities Construction Department, Ft. Bend Independent School District. After reviewing the results of this final test, the district will use the Watts

OneFlow® Technology for future new projects and replacements. 

OneFlow® provided a sizeable vaster protection against scale buildup vs. salt Softener. OneFlow reduced and extensively de-scaled previous buildup. OneFlow, No salt, no maintenance, no backwashing, no regeneration or no monitoring. Since OneFlow® has been installed, Facilities Crews have not even been back in the mechanical room where the system is located. 

With Watts OneFlow, No salt purchases, no salt storage, no replacement salt labor, no monitoring and no salt corrosive damage: OneFlow works and is maintenance free.

OneFlow® is for any owner looking to have protection against scale buildup with no maintenance, no salt, no wasted water and you only need the replacement of the media every three years.
