What are the characteristics of textile effluents?
Typical characteristics of textile effluents The dye effluents are characterized by a strong color, high pH, suspended solids (SS), high total suspended solids, COD, BOD, heavy metals, and different types of salts (Scholz & Yaseen 2018).
What are the physicochemical parameters of wastewater?
The physicochemical parameters were determined such as pH, temperature, turbidity, conductivity, total dissolved solids, total suspended solids, total alkalinity, biological oxygen demand, chemical oxygen demand, dissolved oxygen, total organic carbon, sulphate, nitrate, and phosphate.
What are textile effluents?
Textile effluent is heavily contaminated with pollutants such as dyes, dissolved solids, suspended solids and toxic metals. The main factor to be considered in textile effluent is total dissolved solids (TDS). Because of the use of common salt and Glauber salt, the level of TDS increases in textile wastewater.
What is effluent treatment in textile industry?
Chemical treatment technologies are commonly applied to remove toxic pollutants like dye, toxic metals, and odor from industry effluent wastewater. Chemical treatment techniques can be categorized into advanced oxidation processes (AOP) and chemical oxidation.
What are the characteristics of textile manufacture?
Textile manufacturing is a major industry. It is largely based on the conversion of fibre into yarn, then yarn into fabric. These are then dyed or printed, fabricated into cloth which is then converted into useful goods such as clothing, household items, upholstery and various industrial products.
What is cod in textile?
3.2. COD removal Chemical oxygen demand is a common used parameter for the characterization of organic matter present in textile wastewaters; it depends on the dyes used in the production process. COD removal was observed in all ozonation treatment cases.
What are the physicochemical properties of water?

What are the main sources of pollutants in textile effluent?
Metal contamination in textile effluents occurs due to the presence of dyes and additives used (e.g. caustic soda, sodium carbonate and salts) during the textile manufacturing steps. The main metals, which cause environmental challenges, are chromium, zinc, iron, mercury and lead (Hussein 2013).
What is the role of chemistry in textile industry?
The role of chemistry in textile industry is to develop a wide range of products that can be utilized for dyeing and printing clothes. The process of dyeing clothes employs a large number of chemicals that are used in mixing the paints to get the desired color. These paints blend with the fabric and impart color to it.
What is textile chemical processing?
Textile Chemical Processing provide the complete basic understanding of the fabrics. processing of all type of fabrics which are used into Apparel or Home fashion Industry. It includes Pre-treatments, Dyeing, Printing and Finishing of fabrics. In order to develop knowledge of value addition on fabric, “Textile Chemical.
What does Chemical Oxygen Demand measure?
Chemical Oxygen Demand (COD) is a test that measures the amount of oxygen required to chemically oxidize the organic material and inorganic nutrients, such as Ammonia or Nitrate, present in water.
