Customer Information

• Client name: Ms. Giang – Viet Do Construction Investment and Environment Joint Stock Company
• Product: Dr.Ozone D2 industrial ozone machine
• Quantity: 02 machines
• Requirements: Treatments for color removal from wastewater of paper production

The pulp and paper industry has made significant progress in wastewater treatment in recent years. Contact Dr.Ozone, Viet Do Construction Investment and Environment JSC – Our trusted and long-time partner ordered two Dr.Ozone D2 industrial ozone machines to integrate into the existing wastewater treatment system of the company. Purpose of using ozone for wastewater color treatment.

Before learning about the application of ozone in the color removal of wastewater from the paper production process, let’s see and analyze the characteristics of paper industry wastewater to gain a deeper understanding of the pollution level of this wastewater if is discharged into the environment without treatment.

The Wastewater Of Paper Industry – Composition, Characteristics And Treatment Technology

The wastewater is generated from many different sources in the paper production process.

General of wastewater characteristics from the paper industry

• High suspended solids content
• Excess paper content in wastewater for recycled paper production facilities
• High coloration for paper production facilities from nature
• High organic content, especially in the indicator of total quality of Nitrogen, BOD, COD, etc.

Ozone Solution For Colored Wastewater Treatment Of Paper Industry

Natural clean water is usually colorless and odorless. The color of wastewater is caused mainly by odorants, dissolved substances, colloids or rotting plants. In addition, the presence of some metal ions (Fe, Mn), algae, peat and industrial wastes is also one of the causes of watercolor.

Ozone is a strong oxidizing agent, even at low temperatures, which means it has a fast reaction time and effective color treatment. It also allows the removal of acute toxicity and chlorophenolic acid, increasing the biodegradability of wastewater streams. The color treatment of wastewater is not only good for the environment but also ensures compliance with current regulations on production wastewater before discharge. In addition, ozone also provides another benefit such as improving water quality to can be reusable in production, significantly saving overall water usage in the treatment process.

In this project, our customer used two Dr.Ozone D2 industrial ozone machines, directly under the tank to treat the color of paper production wastewater.
