A disinfection system includes at least one ozone generator; at least one ozone concentration level detector; programmable timer; at least one presence detector; at least one main system process management tool; at least one intermediate system process management tool. This invention aims not only to disinfect the air by removing unpleasant odour, but also to disinfect wastewater, premises and facilities by adjusting ozone concentration. Thus, not only the consequence of bad odour, which appears due to bacteria, protozoa, moulds and other fungi, but also the cause for occurrence of such bad odour is eliminated by exterminating viruses, bacteria, fungi, mould and all the main biogases within the disinfected environment. Modifications of this invention allow adjusting ozone concentration in order to disinfect premises and environment by avoiding possible hazardous ozone impact on people, working in the environments to be disinfected or residing near to such environments.

A waste treatment device may include a solid-liquid separator which is configured to receive and separate waste into solids and liquid. The waste treatment device may further include a solids treatment arrangement which is configured to receive the solids from the solid-liquid separator, wherein the solids treatment arrangement comprises a disinfection unit having a heating mechanism configured to heat, without burning, the solids so as to disinfect the solids to convert the solids into pathogen-free-treated-solids. The waste treatment device may further include a liquid treatment arrangement which is configured to receive the liquid from the solid-liquid separator and to treat the liquid so as to convert the liquid into pathogen-free-effluent. The solid-liquid separator may include a curved-funnel-shaped inner separator surface and a frustoconically-shaped inner liquid guide surface whereby the respective narrower ends are directed towards each other.

A method of sterilizing a waste container with ultraviolet (UV) light is disclosed which includes, inserting an article of waste into the waste container, sealing the container from an external environment to prevent UV light from shining out, activating a UV sanitizing routine stored in a UV light module having at least one UV light source and irradiating an interior surface of the diaper pail with the UV light.

The invention includes a system and method for delivery and storage of an absorbent for solidification of liquid waste. The system includes a plurality of nestable containers configured to receive aqueous liquid to be solidified and forming a packet safe space when nested one within another. The system also includes a plurality of packets at least partially soluble in the aqueous liquid to be solidified. The containers include at least one packet and each packet contains a solidifier for use as an absorbent composition for the aqueous liquid to be solidified. A packet may be housed within the containers inside a packet safe space. The invention also includes an improved system and method for packaging a solidifier for solidification of liquid medical wastes.
