Biologically hazardous wastewater is generated during research in various research centers and laboratories, medical institutions, in the production of vaccines, etc.

In all such cases, there is a risk of contamination of wastewater by pathogenic microorganisms.

In accordance with the requirements of the legislation, infected wastewater must be treated at thermal wastewater disinfection plants before being discharged into the sewer.

For these purposes, it is optimal to use installations for thermal sterilizing treatment of effluents. Such installations are designed for waste contaminated with biological agents of I-IV pathogenicity groups to ensure the operation of:

• Veterinary institutions, vivariums;
• Infectious diseases hospitals and departments;
• Microbiological laboratories for product quality control;
• Research centers and production facilities dealing with virology, bacteriology, epidemiology, biotechnology, genetic engineering, vaccine and serum production;
• Laboratories with BSL2-3-4 hazard level.

The design and principle of operation of the decontamination unit completely exclude any contact of contaminated wastewater with the premises and personnel, as well as the possibility of draining untreated wastewater into the sewer.

Contaminated wastewater is fed into a storage tank designed for the daily volume of wastewater and equipped with control sensors for filling. Then, in an automatic mode, fixed doses are fed into the sterilization container. The organic residues contained in the effluent are disintegrated in the grinder. The sterilization cycle includes filling the sterilization container, heating the liquid by direct steam injection to the sterilization temperature, holding at the sterilization temperature and pressure (135 ° C, 3.5 atm, 90 minutes), cooling to a temperature of no more than 35 ° C and draining the sterilized effluent. The process of accumulation of effluents, filling the sterilizing container, sterilization, cooling and draining is carried out automatically, according to a given program. The control system monitors the operating state of all elements of the installation, documents the process, and stops it in case of emergency situations. If necessary, it is possible to switch to manual control of the process. The process of wastewater treatment is visualized in the form of diagrams and graphs on the control room monitor.

Wastewater decontamination plants supplied by INEX provide guaranteed decontamination of hazardous liquid biological waste. The supplied system is simple and safe to operate, the equipment is fully automated, performing full control of cleaning cycles with self-diagnosis. To increase reliability, the decontamination unit consists of two parallel complete cycle lines, which can be controlled and operated independently or together.

In the normal mode, the lines work, periodically changing each other. The equipment, which has been tested in our factory, can be put into operation as soon as it is turned on.

The installation is quite compact and can be equipped with additional technical options depending on the work task.
