Case study - Textile ETP [Spinners & Spinners]

Published on

Case Study on Textile Waste Water treatment using ozone oxidation & micro-flocculation using ozone in primary stage.
Ozone is used to break complex organic & inorganic molecular bonds of color textile effluent. This significantly reduces use of chemical & sludge. Ozone retrofitting pay back is less than two years. Ozone works quite efficiently on reactive & organic dies to enhance present effluent treatment. Ozone with hydrogen peroxide or UV can offer advance oxidation.

  3. 3. Site Data : Site Location : Nairobi - Kenya ETP Capacity : 100 KLD Present Treatment : Physico-Chemical Process Present Process Scheme : Equalization + Chemical Dosing + Coagulation + Flocculation + Clarifiers + Sand Filter + Carbon Filter
  4. 4. Present Scenario : Color effluent from textile plant : Raw color waste water is collected in equalization tank from different areas. High quantity of chemicals are used to treat this color effluent to make it colorless & then recycled back in process. Due to addition of chemicals TDS of water goes on increasing & due to this blow down water quantity is high. Also due to use of chemicals, operating cost & cost of recycled water is high.
  5. 5. Objective : Enhance Recycled quality of water Reduce Chemical Consumption to reduce Operating cost. Implement Environmental Friendly Technology Higher degree of Compliance
  6. 6. Offered Solution & Technology : Ozonation in equalization tank – Primary stage Ozone is a very strong oxidizing agent. Ozone react much faster than any other oxidizer. Ozone can efficiently break complex molecular bond. Ozone enhances coagulation & flocculation. Crucial part of the solution is to integrate ozone in existing scheme with optimum ozone dose.
