Ideal for drinking water treatment facilities, the new Triton TR8 turbidity analyzer from Electro-Chemical Devices (ECD) optimizes water filter backwash monitoring with intelligent sensor technology.

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 percent. The TR8 TA sensor features an error rate of less than five percent of reading with repeatability greater than 1% percent of reading.

A unique multi-path optical assembly is a feature of the device’s sensor. The first pathway is inside the sensor to a reference detector that compensates for changes in the LED light source caused by aging or other variables. The second pathway has a short path length through the sample, which is best for high concentration measurements. The third pathway has a longer path length, which is best for lower concentrations.

The Triton TR8 utilizes a highly intelligent microprocessor-based design. Its sensor electronics constantly adjusts suspended solids and turbidity signal readings versus the reference detector for superior measurement accuracy. A built-in digital filter helps to suppress potentially interfering signals while self-monitoring diagnostics assure high reliability.

In fact, the sensor was developed for rugged water treatment environments, designed to operate at ambient temperatures from 20-120°F.
