Water purification technology containing antibiotics

Purpose. The technology is designed to protect the environment and human health and can be used to treat wastewater from pharmaceutical and biotech plants to remove antibiotics.

Specifications. Linear resonant traveling wave electron accelerator with a frequency of 2850 MHz, assembled according to a traditional design. The generated beam parameters are as follows: electron energy – 3-4 MeV; electron current – ​​0.5-0.8 A; current pulse duration – 2 µs. An effective absorbed dose of 7.2–30 kGy, required for the complete destruction of antibiotics of different classes at a concentration of 5–50 OA/ml, is achieved in 9–37 minutes.

Application area. Ecology, biotechnology.

Advantages. Known methods for purifying water containing antibiotics do not provide a sufficient degree of purification of water from antibacterial drugs of different groups; they are characterized by the complexity of the process, the need for constant additional addition of consumables or the use of a dangerous radioactive source of gamma radiation. The proposed technology uses a flow of relativistic electrons as an antibiotic destructor, which ensures effective destruction of antibacterial compounds of different classes and does not lead to ionization of surrounding materials. Adding additional reagents to the water is not required, which simplifies the process.

Technical and economic effect. Significant increase in the degree of water purification from antibacterial drugs of different groups by expanding the list of antibiotics subject to destruction (β-lactams, aminoglycosides, tetracyclines, macrolides); reduction of time (10-15 times) required to achieve the effect; absence of reduced radiation in processed water samples; absence of consumables during the treatment process, which reduces consumption and simplifies the process of water purification.

Description. The essence of the technology is the degradation of antibiotics under the influence of a flow of relativistic electrons, which generates a linear resonant electron accelerator. A technology is proposed for purifying water from antibiotics that may be contained in wastewater from pharmaceutical and biotechnological enterprises, achieved by destroying antibiotics during water treatment by irradiation with a flow of relativistic electrons using a linear resonant electron accelerator with an electron energy of 3-4 MeV.
