case studies

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

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
