What is electrochemical destruction?
A cerium-catalysed electrochemical oxidation process, the CerOx Process, is one electrochemical means of destroying waste organic material. Operating at atmospheric pressure, the process can convert organic hazardous waste materials into carbon dioxide and water.
What are the treatment methods for hazardous wastes?
Hazardous waste can be treated by chemical, thermal, biological, and physical methods. Chemical methods include ion exchange, precipitation, oxidation and reduction, and neutralization. Among thermal methods is high-temperature incineration, which not only can detoxify certain organic wastes but also can destroy them.
What do you mean by incineration?
Incineration is a method of treating waste which involves the combustion of the organic substances found in waste materials. The solid mass of the original waste is reduced by around 80 to 85%, while the volume is reduced by between 95 and 96%. When burning waste however, pollutants are created.
What waste can be incinerated?
What can be incinerated?
- Plastic, cardboard, wood.
- Rubber, cloth, oily rags, lub oil filters.
- Diesel engine scavenge scraping.
- Paint scraping.
- Food waste, etc.
- Sludge oil, waste lubrication oil.
- Hospital waste, female hygienic binds.
- Destruction of contaminated water.
What type of waste can be incinerated?
TYPES OF WASTE INCINERATED Three types of waste to which incineration is applied extensively are municipal solid waste, hazardous waste, and medical waste.
What defines hazardous waste?
Simply defined, a hazardous waste is a waste with properties that make it dangerous or capable of having a harmful effect on human health or the environment.
Which waste must be incinerated and why?
Incineration is a key process in the treatment of hazardous wastes and clinical wastes. It is often imperative that medical waste be subjected to the high temperatures of incineration to destroy pathogens and toxic contamination it contains.
Why are incinerators used to burn hazardous waste?
Incinerators Incinerators are used to burn hazardous waste primarily for waste destruction/treatment purposes; however, some energy or material recovery can occur. When performed properly, incineration destroys the toxic organic constituents in hazardous waste and reduces the volume of the waste.
How does electrochemical treatment of organic waste work?
It may also be treated electrochemically to result in carbon dioxide and water. One on-site electrochemical method, described here, which uses platinum-plated titanium electrodes, can treat most organic waste materials very effectively at low temperatures.
Which is better cerox or hazardous waste incinerator?
In fact, compared to a hazardous waste incinerator destroying the same amount of waste materials, the CerOx Process releases about 25 per cent less carbon dioxide (a value that includes the generation of the needed electricity from a fossil fuel fired generation station).
What are the different types of hazardous waste combustion units?
Types of Hazardous Waste Combustion Units. There are two categories of combustion units for solid and liquid hazardous wastes: Incinerators – used primarily for waste destruction. Boilers and Industrial Furnaces (BIFs)- used primarily for energy and material recovery.
