Wastewater from hospitals can contain traces of anything from viruses and multi-resistant bacteria to medical contrast agents and chemicals for cancer treatment. Small amounts of hormone-disrupting substances and other medicine residues are also part of the mix that passes from patients through hospital toilets and into public sewer systems.
According to the World health Organization all medical waste can be classified as follows
The health-care facilities should operate their own wastewater treatment equipment to ensure discharging into municipal sewage system only non-hazardous, fully disinfected wastewater.
Typically, wastewater treatment involves three stages:
– (I) Solids removal;
– (II) converting of dissolved biological matter into a solid mass using indigenous waterborne bacteria;
The third stage removes any residual suspended solids and other materials which were not removed in the previous stages. The effectiveness depends on the quality of the water being treated. The major objective of disinfection is to reduce the number of microorganisms in the waste water to be disposed of in the natural environment.
Common methods of disinfection like electrolysis, chlorination, germicidal rays are outdated or require highly skilled operators and investment costs. And for all that, considering that hospitals are overloaded, the current system requires qualitative changes.
Biomedical waste management solutions. VORTEX LAYER DEVICE BY GLOBECORE
Electromagnetic Vortex Layer Devices AVS-100 and AVS-150 by GlobeCore are
- can be integrated into existing wastewater treatment systems, and
- come in a mobile version, for use in a container.
It is possible to arrange multiple units for increased processing capacity of a production line.
The AVS electromagnetic devices with ferromagnetic elements are designed to intensify various physical and chemical processes.
In the case of medical wastewater AVS device allows achieving removal of more than 95% of bacteria, pathogens and helminthes eggs.
The patented Vortex Layer technology has already shown its efficiency.
It takes only fractions of a second to complete oxidation reactions in this device.
The oxidation reaction in a rotating magnetic field device occurs in a matter of fractions of a second. The entire process ends in 1 or2 minutes. At the same time, in a reactor with agitators, oxidation is much slower.
Beside electrolysis, the following reactions occur in the process section of the vortex layer device during the treatment of wastewater in rotating magnetic fields under the influence of a plasma cloud and a combination of the factors described above:
- deposition of metal hydroxides from solutions;
- chemical reduction of various compounds;
- destruction of pathogenic microflora and microorganisms;
- ionization of water with the release of hydrogen and OH ions;
- anomalous acceleration of chemical reactions.
The combined effect of all the factors sharply increases the activity of all components of the substances involved in the process and allows to change from diffusion type of mass transfer, common for all traditional technologies, to kinetic. This makes it possible to improve the productivity of a process by two or three orders of magnitude and drastically reduce the material and energy costs.
The AVS device can be integrated into existing process lines.
