Method for hazardous waste removal and neutralization

A method of coating a filter medium in a flowing gaseous stream, the method comprising:

• directing a gas stream along a feed path;
• combining with the gas stream a multiplicity of glass dust particles coated with an ignition resistant material;
• positioning a fibrous filter medium along said feed path downstream of the point at which the glass dust particles are combined with said stream, the glass dust particles forming a coating on said filter medium to assist in the capture thereon of hazardous waste material when said stream contains such material;
• and
• intermittently removing the particulate coating material and any such hazardous waste material from the filter medium and collecting the same.

A method of coating a filter medium in a flowing gaseous stream, the method comprising:

• directing a gas stream along a feed path;
• combining with said gas stream a multiplicity of soda lime glass dust particles;
• positioning a fibrous filter medium along said feed path downstream of the point at which the glass dust particles are combined with said stream, the glass dust particles forming a coating on said filter medium to assist in the capture thereon, and combination therewith in situ, of hazardous waste material when said stream contains such material;
• intermittently removing the particulate coating material and any such hazardous waste material from the filter medium and collecting the same;
• and
• combining additional glass dust particles with the collected material.
