Accurate detection of secondary saltwater turbidity analyzer using near-infrared spectroscopy

Product Introduction

Secondary saltwater refers to saltwater produced after electrolysis or other chemical treatment of primary saltwater. It is not pure water, but contains various impurities, the types and contents of which depend on the source of the brine, the treatment process, and the requirements of subsequent applications.

The main components of secondary saltwater, in addition to sodium chloride (NaCl), usually contain calcium, magnesium, sulfate ions, iron hydroxide ions, as well as some organic matter and suspended particles. Its properties and characteristics are mainly reflected in three aspects: corrosiveness, instability, and conductivity. Firstly, the concentration of chloride ions in secondary saltwater is relatively high, which has a certain degree of corrosiveness and potential hazards to equipment and pipelines. Secondly, impurities will precipitate and scale over time, affecting the quality of saltwater and system operation. And the secondary saltwater has good conductivity, which is the basis for its application in electrolysis and other processes.

The application fields of secondary saltwater are quite extensive. In ion membrane electrolysis, it is used to produce important chemical products such as chlorine gas and caustic soda, and is the core raw material of the chlor alkali industry. In the field of fine chemicals, secondary saltwater is used as a reaction medium or raw material in the production of dyes, pharmaceuticals, pesticides, and other products. In addition, in terms of water treatment, secondary saltwater can be used to soften water, remove heavy metals, and reduce the hardness and pollution of water bodies.

Turbidity is an indicator of the degree of turbidity of a liquid, which reflects the content of suspended particles in the liquid. For secondary saltwater, turbidity is a crucial quality parameter that directly affects production efficiency, product quality, and equipment lifespan.

The hazards of high turbidity:

• Blockage of pipelines and equipment: Suspended particulate matter can easily deposit in pipelines, pumps, valves, and other equipment, causing blockages, reducing flow rates, increasing energy consumption, and even leading to equipment damage.

• Impact on electrolysis efficiency: In ion membrane electrolysis, high turbidity can reduce the conductivity and selectivity of the ion membrane, leading to a decrease in electrolysis efficiency, an increase in by-products, and an impact on product purity.

• Polluted products: Suspended particulate matter may enter the final product, reduce product quality, affect product appearance and performance, and even cause safety hazards.

• Increased maintenance costs: In order to remove sediment and replace damaged equipment, a large amount of manpower and material resources are required, which increases maintenance costs.

Secondary saltwater turbidity analyzerDeveloped based on the scattering and absorption principles of near-infrared light, using a split design consisting of a spectral sensor and a multifunctional host. Sensors measure the turbidity and other information of liquids, and perform calculations, displays, and controls on a multifunctional host, suitable for accurate measurement of turbidity in secondary saltwater.
