Water Odor Substance Analysis

With the rapid development of the economy, a large amount of wastewater is discharged into natural water bodies without treatment or without meeting the standards, in which some chemicals, mineral salts, inorganic nitrogen compounds and sulfides can cause odor substances in natural water bodies. In addition, the secretions of algal actinomycetes and fungi in raw water, organic matter such as humus, and biological residues can produce a range of odors, including the typical dimethyl isocarbol, earth odorants, and other more common water odors.

BOC Sciences provides odor testing services for wastewater, including testing for various chemicals and odor removal services.

Testing Methods for Odorants in Water

Sensory Analysis

Sensory analysis refers to the evaluation of water quality by human senses.

Enzyme-linked immunoassay (ELISA)

ELI SA is a new detection and analysis method based on the principle of antigen-antibody reaction, which is widely used in the field of life science in recent years, with the advantage of high sensitivity, suitable for the detection and analysis of specific substances, and easy and fast operation.

Instrumental analysis method

Most of the odor-causing substances in drinking water are caused by organic substances, and the concentration of odor-causing substances is generally in nanograms per liter. The determination of odor-causing substances in drinking water requires high resolution and high sensitivity, and the sample pretreatment process is also a major part of the analysis.

Integrated analysis method

A more reasonable way to analyze the samples can first be qualitative analysis through sensory analysis methods, the initial determination of drinking water odor-causing substances, if necessary, can be further measured through the instrument to quantitative analysis of odor substances and their content.

Odor Detection of Wastewater

Odor is one of the necessary items to test the water quality in source water and treated water, which can trace the source of pollution and judge the effect of water treatment. Odor comes from pollutants in domestic and industrial wastewater, the decomposition of natural substances or microbial activity. Odorless and tasteless water is not guaranteed to be free of contaminants, but it is beneficial to the user's trust in water quality, and is also a sensory indicator of the aesthetic evaluation of water by humans.

Industrial Wastewater Odor Removal

• Chemical deodorization method: the use of odor components and the main components of the chemical solution between the irreversible chemical reaction to generate new odorless substances to achieve the purpose of deodorization; due to the different components of odor need to choose the appropriate chemical agents.
• Biological deodorization method: the use of microorganisms to degrade or transform the organic pollutants in the odor gas into harmless or low-harm substances in the process. The main methods are: biological filtration method, soil method, filling tower biological deodorization method, etc.
• Ionic deodorization method: air in the passage of high-energy ion generation device, oxygen molecules are subject to high-energy electron collisions emitted through the generation device and the formation of oxygen ions with a positive and negative charge, respectively.
