Water treatment plants are used to convert poor quality wastewater into drinkable or usable water. Need to keep the water flowing from these plants quality for normal human use. This plant is used in almost all industries, because quality water needs are personnel necessary for use or operation of the machine.

Water levels are monitored by various types of sensors that help maintain the final output. Without them, the factory would not be able to operate change.

Pressure sensor in water treatment plants

There are many ingredients in water. Therefore, only one type of sensor is not enough to monitor quality.

In water treatment plants, many types of sensors are used to monitor water content. In this article, we will see such some common types of sensors used in plants.

Conductivity sensor

As the name suggests, conductivity refers to the ability of water to conduct electrical current. It is one of the important criteria for determining water quality.

Low conductivity means that the water conducts electricity less well, and this water is pure water. This is because, by contrast, if fruit water contains ions from dissolved salts and other inorganic materials such as chlorides, sulfides, carbon compounds, etc.(referring to dissolved impurities), which conducts electric current due to the presence of a large number of ions. Therefore, higher conductivity means that the water is more conductive, and this water is of lower quality.

A conductivity sensor is installed to measure the conductivity of the water flow. If the conductivity increases to the alarm level, the valve is installed in the system after the sensor to dump the water. This prevents poor quality water from being distributed to the endpoints.

pH sensor

pH represents the potential energy of hydrogen. It is used to specify the acidity or alkalinity of an aqueous solution. This is basically done by checking the hydrogen and the concentration of hydroxide ions was determined.

When there are many free hydrogen ions in the water, it means that the water is acidic; when there are many hydroxide ions in the water, it means that the water is acidic alkaline. Therefore, high-quality water requires neither a low pH nor a high pH. It requires a controlled pH for optimum best performance.

Install a pH sensor to measure the pH of running water. After these sensors, valves are installed in the system, such as water can be dumped if pH rises or falls to alarm levels. This prevents poor quality water from being distributed to the endpoints.

In addition, in addition to the valve, a NaOH metering pump is installed in the system to dispense the required amount of NaOH is added to the water. This is done through precise PID action.

ORP sensor

ORP stands for redox potential. It is the ability of water to oxidize or reduce other chemicals in the water. This means oxidation the higher the action, the purer your water will be. If the ORP is high, it means there is more oxygen in the water, so bacteria that break down dead tissue and contaminants can work more efficiently; because they work consuming a lot of oxygen.

A low ORP means that the water is stagnant and likely to harbor contaminated bacteria; along with the ability to kill them decline. However, keep in mind that ORP cannot be too high. This indicates high levels of chlorine in the water, which are harmful to use.

Therefore, ORP can neither be too high nor too low. High chlorine can also damage equipment installed in water systems. Install an ORP sensor to measure the ORP of water flow. If ORP increases to an alarm level, a valve is installed in the system doors, these valves can dump water behind these sensors. This prevents poor quality water from being distributed to the end point.

Additionally, in addition to the valve, an SMBS metering pump is installed in the system to dispense the required amount of SMBS is metered into water. This is done through precise PID action. SMBS chemicals work by reducing the amount of chlorine in the water if the dose is high. Therefore, PID with it is used to precisely control the flow rate of the dose in the water to maintain the chlorine level.

Turbidity sensor

Turbidity is a visual characteristic of water. It is an optical measurement of water used to determine whether organic and inorganic substances in water are relatively less or more. This is done by scattering light through the water.

If there are more particles, the amount of light reflected will also be high. This means that the turbidity is high and the water is not safe to use. Clean water has fewer or zero particles on the surface, so less light is reflected back. These particles are sometimes visible to the naked eye.

Dissolved oxygen sensor

Oxygen is a very important parameter for water. Life depends on oxygen, the amount of it dissolved in water is healthy necessary necessities. There must be adequate levels of DO (dissolved oxygen) in the water; neither too high nor too low. Antibacterial microbes can be made to stop them from breaking down dead cells and tissues; because they need oxygen to survive.

A dissolved oxygen sensor is installed to measure oxygen in flowing water.

In addition to these sensors, common sensors such as temperature, flow and pressure are also used to monitor their flow and quality, but the sensors discussed above are widely and ubiquitously used in all water systems for monitoring water quality.
