Silicate (SiO\u2082) is a natural component of many bodies of water and enters industrial processes via the raw water. In low concentrations, silicate is inconspicuous – but at just a few ppm, glass-like, extremely hard deposits can form on turbine blades, membranes and heat exchangers. These deposits are very difficult to remove and lead to a loss of performance, increased energy consumption and costly downtime.<\/strong><\/p>\n Silicate monitoring is particularly critical in power plants, ultrapure water systems and wherever mixed-bed filters or reverse osmosis membranes are used. Continuous online monitoring detects the depletion of the filter media at an early stage and protects downstream system components. <\/p>\n The SYCON SiO2 from RLS Wacon is a fully automatic online analyzer for the quantitative determination of the silicate or silica concentration in process water. It works according to the colorimetric method and covers a broad spectrum with two measuring ranges: from ultra-pure water monitoring in the lower ppb range to highly contaminated process water with up to 150 ppm SiO\u2082. <\/p>\n The device offers the full range of functions of the SYCON platform: four relay outputs, Modbus RTU, analog output 4-20 mA, two digital inputs and a 9-language graphical display.<\/p>\n The SYCON SiO2 works according to the colorimetric method<\/strong>. A water sample is automatically fed into the measuring chamber. The reagents are then added: Three reagents (Silicate-A, -B and -C) are used in the LR measuring range (Low Range) and two (Silicate-B and -C) in the HR measuring range (High Range). The reagents generate a color reaction whose intensity is proportional to the silicate concentration. An optical sensor evaluates the color intensity and calculates the measured value. <\/p>\n Before each measurement, the device automatically performs a zero point adjustment to compensate for disturbance variables such as turbidity or contamination. The analysis time is approx. 15 minutes. The measured values are shown on the display and automatically logged on the SD card. <\/p>\n The measured value can be displayed either as silicate (Si) or silicic acid (SiO\u2082) in the units mg\/l, ppm, \u00b5g\/l or ppb.<\/p>\n Two measuring ranges (LR and HR) cover ultrapure water to highly contaminated process water<\/p>\n<\/li>\n Compensates for turbidity, contamination and extraneous light – reliable results even under difficult conditions<\/p>\n<\/li>\n Ideal for monitoring mixed bed filters – recommended between main filter and police filter<\/p>\n<\/li>\n Seamless integration into PLC and SCADA systems for central process monitoring<\/p>\n<\/li>\n Limit value 1, limit value 2, device fault, analysis active \/ cooling water valve \/ reagent message<\/p>\n<\/li>\n All components easily accessible – maintenance of the measuring chamber possible without tools<\/p>\n<\/li>\n No manual calibration required during regular operation<\/p>\n<\/li>\n Complete logging, installation wizard, software updates via SD card<\/p>\n<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":" The SYCON SiO2 is an analyzer for monitoring silicate in the ppm range.
