4. A paint is composed of _
Coloring Agent
Solvent
Drying agent
Additives

5. In a paint pigments are the coloring agents.
That gives the surface a specific color .
White Titanium dioxide
Black Carbon black
Red Iron oxide/cadmium sulfide
Yellow/orange Metallic salts
Blues/green Iron blue/chrome yellow

6. The solvent in paint make it easier to
apply_
 Water based paint WATER
 Oil based paint LINSEED/PETROLIUM
 Latex WATER

7. Resins help the paint dry, _
natural resins most commonly used are
..
Linseed, coconut soybean oil
SYNTHETIC
 alkyds, acrylics, epoxies,
polyurethanes

8. additives serve as everything from
fillers to anti fungicidal agents
fillers
calcium carbonate, aluminum silicate
Other additives
thixotropic agents that gives paint its
smooth texture, driers, anti-settling
agents,defoamers

9. Paint are classify on the basis of
 Functions
1. Rust inhibiting paint
2. Fire proof
3. Heat resistant paint
 Application
1. Interior
2. exterior

11. To eliminate the
 Toxic Pollutants
That caused harmful effects to living
 Microbial contamination
Deterioration of product quality

12. Pre-Operative

13. POST-OPERATIVE :

14.  There are three common techniques use to
treat waste water
 Bio-degradation
 Chemical coagulation
 Cross flow microfiltration

15.  Biodegradation in which organic compounds
are decomposed by microbes e.g bacteria
Pollutants generated from paint industries
contain mixture of toxic organic solvents.
 ethylene glycol,
 propylene glycol
 iso-butanol

16.  In water treatment, coagulation occurs when
a coagulant is added to water to "destabilize"
colloidal suspensions.
 Alum
 Aluminum sulphate
 coagulation is one of the cheapest process
for treatment of various organic effluents.

17. The cross-flow microfiltration unit consisted of
a cellulose acetate membrane with pore size
0.2 mm, makes water free of suspended
matter, bacteria and colloidal matter.
