The turbidity of saltwater at one time
Thread Content
Why is the turbidity of saltwater high at one time? What steps need to be taken to meet the required standards? What is the difference between turbidity and SS?
Could you explain it in detail? Is it a turbidity issue?
Saw it on another version, so came to take a look. ＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝ The concept of water turbidity in our country – it refers to the degree of turbidity, also simply known as turbidity level. Due to the presence of particles in suspended and colloidal states in water, water that was originally colorless and transparent becomes turbid; the degree of this turbidity is referred to as turbidity. The unit for turbidity is expressed in “degrees”; it corresponds to a turbidity level of 1 degree, or Jackson unit, when 1 mg of SiO2 (or an equivalent amount of white clay or diatomite) is present in 1 L of water. SS refers to solid substances suspended in water, including water-insoluble inorganic substances, organic substances, as well as sediment, clay, microorganisms, etc. The suspended solids content in water is one of the indicators used to measure the degree of water pollution. Suspended solids are the main cause of water turbidity. Organic suspended matter in water bodies tends to undergo anaerobic fermentation upon deposition, leading to water quality deterioration. China’s comprehensive wastewater discharge standards are divided into three levels, which specify the maximum allowable concentrations of suspended solids in wastewater and effluents. China’s groundwater quality standards and drinking water hygiene standards define suspended solids in water using turbidity as an indicator. Determination of suspended solids: refers to the solids that remain on the filter media and are dried at 103–105°C until a constant weight is reached. The method of determination involves passing the water sample through filter media, then drying the solid residues and the filter media; the suspended solids (total non-filterable residue) are obtained by subtracting the weight of the filter media from the measured weight. Measurement of turbidity: Turbidity indicates the degree to which suspended particles in water interfere with the passage of light. Determined by photometry.
