Process- Paint Sludge

�Every year India generates 65,000 Tonnes of Industrial Paint

sludge. Of these, 40, 000 Tonnes are from organized sector, which

can be responsibly disposed.

�Presently, the paint sludge are air-dried in waste sheds and then

disposed by incineration or as alternate fuel in cement kilns through

co-processing

�Cost of incineration is Rs.20,000 per ton and cost of co-processing

Current Disposal Practices

�Cost of incineration is Rs.20,000 per ton and cost of co-processing

in cement kilns is Rs. 8,000-10,000 per ton.

Industrial Air Purification Technology

Photo catalysis oxidation process

Adsorption processUsing Activate carbon

Purified air out

High Particulate Efficiency: The HEPA filter will

remove 99.97% of 0.3 micron particles from the air that

passes through the filter.

Odor Removal: Photo catalysis oxidation (UV TiO2)

and treated activated carbon filter helps remove odors gas

(VOC gases) such as organic solvent smoke, and pet

smells from the air.

Microbial Control: the action of UV light in order to

Filtration Process pre filter and secondary filter

Polluted Air in

Microbial Control: the action of UV light in order to

destroy contagious and infectious, airborne micro-

organisms such as bacteria, staphylococcus, hepatitis,

virus and other harmful, viable organism

Quiet/ Programmable : The air purifier has been

designed to operate quietly and efficiently. You can

choose among four speeds to best meet your needs at

different times.
