Turbidity Analyzer

September 11, 2012

The Triton TR8 Turbidity Analyzer from Electro-Chemical Devices (ECD) is ideal for monitoring turbidity in filter backwashing systems to optimize drinking water plant efficiency. Filter backwashing is a critical part of the drinking water production process. During backwashing, water flow is reversed and increased in order to flush out debris and particles. Turbidity is used to monitor the progress of the cleaning, and when the turbidity returns to a value near the turbidity of the clear well water the backwash cycle is stopped. Backwashing cleans the filter to preserve water quality and also extends the life of the filter; however, backwashing too frequently can lead to degraded filter performance. Accurately measuring the turbidity of the water coming out of the filter is the best way to determine when backwashing should occur, optimizing drinking water plant performance and minimizing operating costs. The Triton TR8 Clear Water Sensor is ideal for all phases of drinking water processing including filter backwash. The highly accurate Triton TR8 TA operates over wide measurement range with output available in multiple units: 0.000 to 9999 FNU, or 0.00 to 3000 ppm, or 0.0 to 3.0 g/l, or 0 to 20%. The TR8 TA sensor features an error rate of less than 5% of reading with repeatability greater than 1% percent of reading.
