Water treatment solutions in water supply sector

Instrumentation equipment

Outline

To perform plant operations safely and stably, it is important to capture individual conditions precisely. In the case of water treatment, identifying water quality is essential besides the process measurement of flow rate and water level.

METAWATER Co., Ltd. offers its unique water quality measuring systems that can address all of these aspects. We offer the optimum solutions to realize stable plant control including the selection and application of plant equipment by making positive use of our know-how.

Water quality safety monitor - Detection of acute toxic material in raw water -

Water quality safety monitor

Characteristics

  • Toxic material sensor using bio-assay method based on microorganism (nitrobacteria)
  • Because microorganisms are used, high sensitivity and objective monitoring is possible.
  • Around-the-clock continuous monitoring (excluding calibration time: continuous operation is possible by adopting tandem option)
  • Maintenance frequency: Normally every 2 months (may vary depending on installation environment)
  • Sensitivity fluctuation depending on raw water quality is minimized.

High sensitivity turbidimeter series - Management of filtration tank -

High sensitivity turbidimeter series

Characteristics

  • Particle count approach makes it possible to measure particle concentration simultaneously with turbidity measurement.
  • Particles up to Φ100 μm can be counted (hybrid particle counter)
  • Ideal for filtration tank management and detection of membrane breakage of membrane treatment equipment
  • Maintenance frequency: Normally monthly (may vary depending on installation environment)
  • Besides high-performance hybrid particle counter, standard high sensitivity turbidimeter is available

Trihalomethane meter - Continuous monitoring of total trihalomethane -

Trihalomethane meter

Characteristics

  • Continuous monitoring of trihalomethane level is possible without pre-processing by using membrane separation - fluorometry.
  • High correlation with GC-MS approach
  • Maintenance cost is reduced by approx. 50% (based on annual spare item cost, versus conventional items)
  • Maintenance frequency: Normally every 2 months (may vary depending on installation environment)
  • Measurement of up to three systems is possible by automatic switching (switch system is optional)
