Do You Know The Significance of The Efficient ORP Sensor And How It Helps to Treat Water?

When testing water quality, it’s critical to understand oxidation-reduction potential and what this assessment means. ORP or Oxidation-Reduction Potential sensor is a measurement that determines a substance’s ability to reduce or oxidise another substance. ORP measurements can be taken in water and comparable solutions using electrodes within an ORP sensor. When this sensor returns a negative reading, it indicates that the measured substance is a reducing agent. On the other hand, positive readings reflect that the solution is an oxidising agent.

Oxidation and reduction in this process:

Before performing liquid interpretation, you should understand the concepts of reduction and oxidation. Oxidation is a chemical reaction when a substance lacks electrons and must obtain them from another agent inside the solution.

When electrons have an excess of ions, they may be able to supply some to various oxidising agents. These are known as reducing agents and always generate negative ORP readings. While using this type of sensor, these substances will produce positive results, which is why they are classified as oxidising agents.

 

Why is the ORP reading important?

ORP readings indicate how contaminated or sanitised the water is when testing its quality. If water is treated for recycling or consumption, sanitised water will have a higher ORP measurement. Contaminated water, on the other hand, typically has low ORP readings. Oxidation-reduction potential sensors are made of two separate electrodes and have a design similar to pH sensors.

A reference electrode and an ORP electrode are among the two electrodes. When the ORP electrode is immersed in the solution, it either accepts electrons from a reducing agent or gives electrons to an oxidising agent. This process will be repeated until monitoring is obtained that equals the solution’s exact ORP.

 

How is ORP used?

The oxidation-reduction potential is critical reading when attempting to determine the water quality or a similar solution. This assessment can determine whether one substance can reduce or oxidise another.

While ORP monitoring is used for various reasons, the most important is to determine how contaminated or sanitised water is. A high ORP reading indicates that the solution in which the ORP detector is placed should contain an oxidising agent. Lower readings show the inverse.

Whether you want to ensure that the water is safe to drink or keep your boiler water free of pollutants, the ORP metrics you obtain will provide you with all the information you need to determine if additional sanitation or disinfection is required. Water must have a high ORP reading to be safe to recycle or consume. It indicates that the water has been properly sanitised.

ORP readings are especially important when ensuring that the water is nearly free of contaminants. When water is deemed safe to drink, its ORP reading typically ranges between 200 and 600mV. Readings that exceed -100mV, on the other hand, imply that the water may be too polluted to drink. Without these inappropriate readings, it can be difficult to determine how contaminated or sterilised water is.

While disinfected water has ORP readings of around 600-700mV, fully sterilised water has ORP readings that exceed 800mV. Understanding the various variables influencing ORP readings will help you determine why your water’s quality is changing.

 

Where are ORP detectors used?

ORP sensors can provide a wide range of measurements that can be useful in various applications. This type of sensor is commonly used in the following applications:

  • Disinfection and chlorine,
  • Swimming pools,
  • Water treatment,
  • Poultry processing and
  • Pulp bleaching.

When it comes to public pools, ORP is usually used to assess the water quality in chlorinated pools. As it is directly affected by every agent in the water, ORP devices can give you lots of information that pH sensors cannot. A pH sensor can only detect hydroxide ions and hydrogen ions.

If you have a larger pool in your yard, there’s a good chance it’s already equipped with an inline ORP sensor. If it doesn’t, there are numerous portable ORP sensors available.

 

Understanding the ORP measurement:

ORP sensors can provide you with more data than a pH sensor alone. As a result, ORP measurements are critical when evaluating water quality.

The presence of an oxidising agent in the water helps to ensure that most contaminants are removed. If your ORP reading is lower than expected, it’s possible that you didn’t add enough chlorine or that the chlorine is no longer working properly.

All ORP sensors have two distinct electrodes that can provide accurate ORP readings. A reference electrode and an ORP electrode are among these electrodes. The reference electrode is the same as the one used in a pH sensor to evaluate the readings. The ORP electrode either stops or receives electrons until a reading that is equivalent to the ORP of the water is obtained. A poor reading after adding chlorine to your pool water indicates that new chlorine may be required.

 

ORP Electrode:

Key features:

  • Spherical Bulb: large pH glass for quick response.
  • Ceramic junction (431): Suitable for pressure applications. It is not recommended for fast flow.
  • “H” pH glass (435): Designed for high temperatures up to 135°C and extreme ph values, with high accuracy in the alkaline range. 

It is an ideal solution for measuring heavy media via in-line submersion (PH650CD) or hot-tap application (PH655CD). All are double-sided and have a connector outline. Flat glass ensures effective self-cleaning. Flat glass has a high mechanical resistance and a stable and slow response time. It is not recommended for pH7/0mV values.

  • HDPE junction: Recommended for dirty liquids and high flow rates.
  • Special version for HF (max 2%) and low conductivity (10 microS< conductivity< 100 microS).
  • Special version DA for signal amplification over long distances.

 Whenever the solution for conducting in-line and submersion measurements in heavy media. The electrodes include a temperature sensor and a 5MT cable. They are double-junction, and the flat glass ensures efficient self-cleaning.

  • Flat glass has a high mechanical resistance and a stable and slow response time. It is not recommended for pH7/0mV values.
  • HDPE junction: Recommended for dirty liquids and high flow rates.
  • Special version for HF (up to 2%), low conductivity (10 microS< conductivity< 100 microS).
  • Threads are double 34″ for in-line and submersible setups.
  • Temperature compensation with Pt1000.

 

The parameters of ORP you should follow:                                       

  • When you are determined to add chlorine to your pool water, the chlorine will give up excess electrons, oxidising any harmful bacteria in the water. When chlorine electrons are active in the water, the ORP readings rise to account for the addition of an oxidising agent.
  • If you decide to test your chlorinated pool water, you should get readings between 650 and 750mV. These readings will fall over time as the chlorine in the water degrades and dissipates.
  • ORP readings should range from 200-400mV for cooling towers and aquaculture applications. If you get readings in cooling tower water less than 200mV, the water may contain too many contaminants, increasing the likelihood of scale development and other problems. If you’re treating water to ensure safety to drinking, your readings can range from 650 to 850mV. Any water above 800mV is considered sterilised, indicating that there are almost no contaminants in the water.

 

Significance of the FIP standard:

The sensor, suitable for use with all solid-free liquids, can evaluate flow rates as low as 0.25 M/S (0.8 FT/S). As a result, it generates a frequency output signal with a very small dimension. Its unique design allows it to be used on FIP standard Tee-fittings ranging from DN15 to DN40 (0.5 TO 1.5 IN).

Therefore, people should always consider the FIP standards for better management.
