Before
Before Sustainachem Started Treating the System:
- Calcium cycles were 1.65 with conductivity cycles at 2.6 (Scale Forming)
- Iron levels were 1.31 ppm (Under Deposit Corrosion)
- Zinc levels 1.4 ppm (White Rust)
- Ammonia leak in the system (High Acid Feed and Blowdown Masking)
- Feeding sulfuric acid (Overfeeding due to leak)
- Sulfate reducing bacteria and legionella present
- Spending $115,000 on water treatment chemicals
- Fans running hard due to poor heat transfer

After Sustainachem Took Over (10 Months)
- Calcium cycles 4.1 and conductivity cycles 3.8 (Removing Scale)
- Iron levels - 0 ppm
- Zinc levels - 0 ppm
- Changed acid feed
- Added proper biocides and cleaned up system
- No legionella present
- Spending less than 1/2 of previous spend
- Water savings of 3 MGal/yr by cycling and fixing leaks
- Energy savings of $62,800 from clean coil

Before Sustainachem Took Over The Site:
- Filters were being changed out every two weeks as seen above
- Iron levels were 311 ppm total with 171 ppm FE2+ (Corrosion)
- Plugged strainers and coils restricting flow
- Overworking compressors and leading to failure of 3-4/yr
- Spending $45k/yr on replacement heat pumps

Extremely High Iron
After Sustainachem Took Over:
- Picture above is after 24 hours of treatment
- Iron was down from 311 ppm to 17 ppm
- After 4 days iron was down to 0 ppm soluble
- Filters no longer being replaced as they are clean
- No plugged strainers
- No more replacement compressors
