water quality monitoring

water quality monitoring

Ambient air quality monitoring is the systematic assessment of pollutant levels in the outdoor environment. It plays a vital role in understanding environmental health, ensuring regulatory compliance, and guiding informed decision-making.

Comprehensive Instrumentation Solutions for Water Treatment by Clean Metric

Clean Metric offers a full suite of process instrumentation and smart monitoring technologies that enable efficient, safe, and regulatory-compliant water treatment across all stages—from raw water intake to final distribution. Our advanced solutions integrate seamlessly with SCADA systems for complete control and real-time decision-making.

Process: Water is drawn from natural sources such as rivers, lakes, or groundwater.
Instrumentation:

  • Flow meters – to monitor intake volume

  • Level sensors – in intake wells/tanks

  • pH and turbidity sensors – for basic water quality screening

Processes:

  • Screening: Removal of large debris

  • Aeration (optional): Adds oxygen, removes volatile gases

  • Chemical Dosing (pre-oxidation): Initial disinfection/taste-odor control

Instrumentation:

  • Level sensors – debris build-up

  • Differential pressure sensors – across screens

  • Dissolved oxygen sensors – for aeration control

  • Flow meters – for chemical dosing pumps

  • ORP sensors – to monitor oxidation and disinfection efficiency

Processes:

  • Coagulation: Dosing coagulants like alum or ferric chloride

  • Flocculation: Gentle mixing to form larger particles

Instrumentation:

  • Pressure sensors – in the network to detect drops/leaks

Key Process Instrumentation Categories

* Flow: Measures the rate and total volume of water and chemicals. Examples include magnetic flow meters, ultrasonic flow meters, and variable area meters.
* Level: Monitors the height of water or sludge in tanks and basins. Examples include ultrasonic level sensors, pressure transducers, and float switches.
* Pressure: Measures the force exerted by the water, crucial for pump control and leak detection. Examples include pressure transmitters and pressure gauges.
* Water Quality: Analyzes various chemical and physical properties of the water. Examples include pH sensors, turbidity meters, conductivity sensors, dissolved oxygen sensors, ORP sensors, and residual disinfectant analyzers.
* Actuation and Control: Includes valves (controlled by pneumatic, electric, or hydraulic actuators), pumps (with variable speed drives), and Programmable Logic Controllers (PLCs) that automate and manage the treatment processes based on sensor readings.
Supervisory Control and Data Acquisition (SCADA) System:
It’s important to note that all these instruments are typically connected to a central SCADA system. This system allows plant operators to monitor all parameters in real-time, control equipment remotely, log data, generate reports, and respond to alarms, ensuring the efficient and safe operation of the entire water treatment plant.
While this description doesn’t provide a visual diagram, it outlines the typical stages and highlights the critical role of process instrumentation at each step to ensure effective water treatment.
