1. Fewer resources and increased operator demands
2. Raw or influent water with fluctuating turbidity. This is particularly common in surface water treatment plants
3. Goals to improve quality, specifically reduction of turbidity and improved water color
4. Goals to reduce costs of chemical usage
5. Maintaining process control in weather events

As one example, a customer in a surface water treatment application saw tremendous benefit from the use of implementing a Streaming Current Detector into their process. Heavy rains caused dramatic and rapid fluctuation of raw water turbidity and color (5-400 NTU; 10 - 300 PtCo).

Prior to using a Streaming Current Detector, this plant regularly:

• Conducted Jar Tests more than 2 times a day to determine proper Alum dose rate
• Resulting treated water, effluent, varied from 0.7-1.2 NTU and 5-10 Pt Co; with higher results during rain events
• Overran chemical budget regularly

After installation and setup of the Streaming Current Detector:

• Jar Tests totally eliminated - allowing the treatment team to focus on other tasks
• Complete automated control of Alum dose rate
• Effluent Water Quality improved: less than 0.7 NTU and less than 1 PtCo, even during weather events
• Alum cost reduced by 50%, Lime reduced by 50%, Polymer use (for color) totally eliminated. These chemical cost reductions paid for the streaming current detector in less than 1 year of use!
