On-site Pilot Project for Pharmaceutical Wastewater Treatment

Recently, Keleer Technology's CDOF equipment (Cyclonic Dissolved Ozone Flotation Unit) successfully completed a pilot test for pharmaceutical wastewater treatment at a large pharmaceutical group in Inner Mongolia, achieving a new breakthrough in the application of ozone advanced catalytic oxidation technology in the field of pharmaceutical wastewater treatment. It is reported that the pharmaceutical group is a large comprehensive pharmaceutical enterprise in China that produces antibiotics, semi-synthetic antibiotics, chemical synthetic raw materials, and other formulations and raw materials. The efficient treatment of pharmaceutical wastewater has always been a technical problem that has troubled the company's development.


Pharmaceutical Wastewater Treatment Effect

In recent years, with the continuous development of the pharmaceutical industry, the problem of pharmaceutical wastewater pollution has become increasingly prominent. The treatment of pharmaceutical wastewater is complex and unique, mainly due to the following aspects:

1.Complexity of Pharmaceutical Wastewater Composition: Pharmaceutical wastewater contains complex organic compounds, drug residues, and various harmful substances. The drugs and auxiliary materials used in the production process, as well as residues from patient medication, all enter the wastewater. These substances are highly stable and difficult to degrade, posing potential hazards to human health and the environment, presenting a challenge to traditional wastewater treatment methods.

2.Presence of Large Amounts of Trace Pharmaceuticals: Pharmaceutical wastewater contains a large number of trace pharmaceuticals such as antibiotics, analgesics, and anticancer drugs, which exist in trace amounts. Even at low concentrations, these trace pharmaceuticals have certain toxicity and ecological risks, posing harm to aquatic environments and organisms.

3.Contamination by Heavy Metal Ions: Commonly used metal coordination compounds and metal catalysts in the pharmaceutical industry are released into wastewater during formulation. These heavy metal ions are not only toxic but can also enter the food chain through biological enrichment, posing a potential threat to ecosystems.

4.Presence of Antibiotics and Antialgal Agents: Pharmaceutical wastewater often contains a large amount of antibiotics and antialgal agents, which have strong resistance and inhibit the growth of microorganisms and algae produced in the wastewater treatment process.

5.Large Fluctuations in Flow Rate and Water Quality: The flow rate of pharmaceutical wastewater from hospitals and pharmaceutical factories fluctuates with different time periods and production processes. Additionally, the water quality characteristics of pharmaceutical wastewater vary greatly. Harmful substances in pharmaceutical wastewater are usually present in high concentrations and fluctuate greatly. This requires addressing the challenge of controlling and stabilizing the concentration of wastewater during treatment, requiring wastewater treatment equipment to have the ability to handle variable water quality and be highly adaptive.

6.High Technical Requirements: The treatment of pharmaceutical wastewater requires the use of highly technical treatment processes, including biodegradation, membrane separation, and advanced oxidation. This poses certain difficulties in the selection and operation and maintenance of wastewater treatment equipment.

To address these challenges, advanced treatment technologies and equipment are required, along with effective monitoring and management measures to ensure the safe treatment and discharge of pharmaceutical wastewater.

In the face of the complexity and uniqueness of pharmaceutical wastewater treatment, Sinokle Technology uses its patented technology, the CDOF-Cyclonic Dissolved Ozone Flotation Unit, as the core technology to deeply treat pharmaceutical wastewater in this project. This overcomes the shortcomings of traditional processes and perfectly solves the problem of pharmaceutical wastewater treatment. The CDOF equipment effectively degrades organic compounds, drug residues, and heavy metal ions in pharmaceutical wastewater, meeting national standards for discharge requirements. Additionally, the adaptability of Sinokle's CDOF equipment can effectively address the challenges of different water qualities and fluctuations in pharmaceutical wastewater.

Technical Principles

Ozone Oxidation: The mechanism of ozone reaction in water utilizes the oxidative property of ozone (oxidation potential of 2.03V) to directly oxidize organic compounds in water, or to oxidatively decompose large organic compounds into smaller ones, making them easier to degrade. Although pure ozone oxidation can remove organic matter to a certain extent, ozone is difficult to further oxidize the oxidized small molecular substances, so pure ozone oxidation has certain limitations in the mineralization of organic matter.

Ozone Catalytic Oxidation: By adding catalysts to the ozone system, the ability of the ozone system to produce hydroxyl radicals can be significantly improved, and the ability of ozone to directly oxidize organic matter can be improved. This is a new technology developed to address the low efficiency of ozone oxidation alone.


Highly Efficient Ozone Catalysts developed by Sinokle

After biochemical treatment of pharmaceutical wastewater containing various complex components and harmful substances, the COD value significantly decreased. The subsequent use of the ozone catalytic oxidation-air flotation integrated process resulted in a low investment and operating cost with excellent effectiveness.

The successful application of Keleer's CDOF equipment in the pilot test for pharmaceutical wastewater treatment provides an effective technical approach to solving pharmaceutical wastewater pollution. In the future, Keleer Technology will further promote the application of this technology in the actual treatment of pharmaceutical wastewater, making greater contributions to protecting water environments and maintaining public health.
