Suspended Solids Analyzer
The working principle of the suspended solids (sludge) concentration meter is based on optical laws and photoelectric conversion technology. Its core logic lies in leveraging the absorption, reflection, and scattering effects of suspended particles in water on light to establish a quantitative relationship between the transmittance of incident light and the concentration of suspended solids. Optical studies have shown that there is an inverse proportional relationship between the concentration of suspended solids in water samples and the transmittance of incident light. That is, the higher the concentration of suspended solids, the greater the degree to which suspended particles "intercept" the light during its transmission in the water sample, resulting in less light being able to transmit through. Regarding the operation of the instrument, the MLSS suspended solids (sludge) concentration meter is equipped with a built-in infrared light source. When in operation, this light source emits infrared beams that penetrate the water sample. During the propagation process, the beams encounter suspended particles. Some of the light is absorbed and converted into heat energy, some is reflected and changes its propagation direction, and some deviates from its original path due to scattering, leaving only a small amount of light able to reach the built-in detector. The detector converts the received optical signal into an electrical signal, and the instrument further uses the Lambert-Beer law to calculate the detected transmittance data, ultimately converting it into the corresponding value of suspended solids concentration, thus achieving the quantitative detection of suspended solids content in water samples.

1. Environmental Protection Industry
In environmental monitoring, suspended solids (sludge) concentration meters are indispensable tools. They are widely used in surface water quality monitoring, such as in rivers, lakes, and reservoirs. By measuring the concentration of suspended solids, environmental scientists can assess the degree of water pollution. High concentrations of suspended solids may indicate serious soil erosion, industrial wastewater discharge, or domestic sewage pollution. In addition, in marine environmental monitoring, these meters help study the impact of coastal activities on the marine environment, such as sediment transport and the influence of river runoff on the ocean.
2. Water Treatment Industry
This industry relies heavily on suspended solids concentration meters. In industrial wastewater treatment plants of various industries, including chemical, pharmaceutical, and food processing, the meters are used to monitor the quality of wastewater at different treatment stages. They assist in adjusting treatment processes, such as determining the appropriate dosage of flocculants and coagulants, to ensure that the treated wastewater meets the discharge standards. In domestic sewage treatment plants, the meters play a crucial role in optimizing the treatment process, from the initial sedimentation to the final disinfection stage, ensuring the efficient operation of the entire sewage treatment system.
3. Mining and Mineral Processing Industry
In the mining sector, suspended solids concentration meters are essential for ore beneficiation processes. For example, in copper, gold, and iron ore mining, during the separation of valuable minerals from gangue through methods like flotation and gravity separation, monitoring the concentration of suspended solids in the slurry helps control the process parameters, improve the recovery rate of minerals, and reduce resource waste. In tailings management, measuring the suspended solids concentration in tailings water is critical for preventing environmental pollution and exploring the possibility of resource recycling from tailings.
4. Aquaculture Industry
In aquaculture, maintaining good water quality is vital for the growth and health of aquatic organisms. Suspended solids concentration meters are used in pond and cage aquaculture to monitor water quality in real - time. Excessive suspended solids can reduce water transparency, affect the photosynthesis of aquatic plants, and even harm the gills of fish and shrimp. By regularly measuring the suspended solids concentration, aquaculture farmers can take timely measures, such as water exchange and the use of water purification equipment, to create a suitable living environment for aquatic animals and improve aquaculture efficiency.
5. Power Generation Industry
In thermal power plants, suspended solids concentration meters are used to monitor the quality of cooling water. High concentrations of suspended solids in cooling water can cause scaling and fouling in heat exchangers, reducing heat transfer efficiency and increasing energy consumption. By continuously monitoring the suspended solids concentration, power plant operators can take appropriate water treatment measures, such as filtration and chemical treatment, to ensure the normal operation of equipment and improve the overall efficiency of power generation.
