What is a Turbidity Sensor?


Water turbidity directly affects water quality. It is determined by observing light scattering on the water's surface. When light scatters a lot, it indicates high turbidity. This turbidity could be due to various substances like silt, clay, organic and inorganic materials, dissolved organic compounds, and algae. High turbidity readings signal water contamination, necessitating treatment before the water is suitable for industrial use or consumption.


Regular Monitoring with Turbidity Sensors

For consistent turbidity measurement, employing turbidity sensors is essential. These inline sensors are installable at different stages of industrial processes. They quickly gauge the water's particulate matter content. Turbidity sensors have broad applications, including:

● Monitoring Clean-In-Place (CIP) return lines.

● Assisting in phase separation for various products.

● Enhancing yeast harvest in breweries.

● Checking raw material quality at receiving bays.

● Detecting leaks in gaskets and filters.

Identifying phase transitions, like changes between products, cleaning agents, and water.

A turbidity tester helps determine if water has been adequately filtered or needs further treatment, regardless of the specific application.


Utilizing a Turbidity Sensor

Turbidity sensors, by identifying water clarity, play a crucial role in quality assessment. They work by measuring light scattering caused by particulates in the water. Higher than-expected scattering indicates significant contamination. Note that only undissolved particles impact light scattering.

Purified water, nearly devoid of solid particles, results in low turbidity readings. Turbidity sensors are versatile and useful in applications ranging from leak detection to brewery operations and water treatment processes. They enable facilities to gauge particulate concentration and decide on further treatment needs. Precise turbidity measurements are vital in many industrial scenarios. The sensor quantifies all suspended solids, providing clear data on required water treatment.

Turbidity Measurements: Why They Matter

The significance of turbidity measurements varies based on context. High turbidity in streams can lead to siltation, affecting aquatic habitats. Suspended solids increase the risk of water pollution, potentially introducing bacteria and metals. Turbidity sensors are instrumental in assessing water body pollution.

From a human health perspective, turbidity sensors ensure drinking water safety. High turbidity in drinking water can cause health issues, as it offers a conducive environment for pathogen survival and proliferation, raising the risk of waterborne diseases. Thus, achieving low turbidity readings is crucial for drinking water or wastewater.

How Turbidity is Measured

The approach to measuring water turbidity varies based on the sensor's application. In river scenarios, sensors provide immediate turbidity levels. Extended into the water, these devices house a turbidity sensor at their end. The sensor measures turbidity by emitting light into the water and detecting the reflected light. More reflected light indicates higher river turbidity. These devices can be equipped with multiple sensors, like conductivity and pH sensors, for comprehensive analysis.

In rivers, high turbidity often presents as cloudy or opaque water. Low-flow conditions typically show turbidity under 10 NTU, often with a greenish tint. Contrastingly, rainstorms can introduce land particles into rivers, turning the water muddy brown and elevating turbidity readings. Fast-flowing water can also stir up materials from the riverbed, increasing turbidity.

Choosing the Right Turbidity Sensor

Different turbidity sensors cater to various needs, including wastewater, water treatment, food and beverage industries, power generation, chemical processing, and life sciences. The three main types of sensors are nephelometric, suspended solids, and absorption sensors. Nephelometric sensors operate on light scattering principles and are ideal for low turbidity water like potable water. Suspended solids sensors suit high turbidity measurements and are often used in wastewater. Absorption sensors, suitable for fluctuating turbidity values, detect light absorbed by particles.

Nephelometric sensors use a light detector and an LED lamp, with the detector positioned at a 90-degree angle to detect scattered light. Absorption sensors, conversely, place the light detector opposite the lamp to measure light attenuation by particles. Advanced models offer more precise readings. Suspended solids sensors employ a backscattering light technique with two detectors, ideal for high turbidity applications.

Advantages of Turbidity Sensors

Turbidity sensors offer several benefits. They come in diverse types, accommodating different water quality measurement needs. Along with sensors, there are turbidity transmitters and accessories for accurate readings. These sensors offer flexibility in deployment and are suitable for inline measurements, basins, tanks, or open channels. They provide readings in various units, like FTU, NTU, and FNU.

Turbidity sensors are user-friendly, delivering quick results. They are a cost-effective solution, offering a rapid return on investment with precise results, enhancing yields or reducing cleaning consumables. Understanding these sensors' workings assists in selecting the appropriate type for specific needs.
