indoor air quality

going back 2d basics…plants absorb co2 n produces o2 thru photosynthesis….here’s a talk bout d topic of producing fresh air 2improve indoor air quality….

2address indoor air pollution if ever u have only few plants inside ur bldgs…..we can use light bulbs coated w/ titanium dioxide. tis kind of light bulbs destroys harmfull gases, eliminate odor causing chemicals, kills airborne mold spores, create a germ-free work area, etc…..btw, it also a light bulb dat will light ur house….

d bulbs are self-cleaning & cleans d air thru photocatalysis……cool technology…..though quite expensive…but w/ itz capabilities aside fr producing light…..itz worth it….can’t wait 2get my hands on my upcoming samples…..

    ms vina,
    yup, ti02 can be found in many products….specially w/ sunscreens….check tis out:
    “In almost every sunscreen with a physical blocker, titanium dioxide is found because of its high refractive index, its strong UV light absorbing capabilities and its resistance to discoloration under ultraviolet light. This advantage enhances its stability and ability to protect the skin from ultraviolet light. Sunscreens designed for infants or people with sensitive skin are often based on titanium dioxide and/or zinc oxide, as these mineral UV blockers are less likely to cause skin irritation than chemical UV absorber ingredients, such as avobenzone. The titanium dioxide particles used in sunscreens have to be coated with silica or alumina, because titanium dioxide creates radicals in the photo catalytic reaction. These radicals are carcinogenic, and could damage the skin.”

    There are two common procedures used in treating wastewater of dyestuffs components one is thru Chemical precipitation i.e, pH adjustment followed by coagulation then flocculation and sedimentation. Sludge collected can be pumped to a filter press. Another procedure is thru Nanofiltration or Microfiltartion similar to Reverse Osmosis system.This one is easier to operate but more expensive in terms of initial cost. Chemical precipitation is most commonly used

      Thanks Mr. Baysa. What would be the most cost-effective process? Any recommendations on where to get specific information on these?

    that’s cool! my brother said titanium dioxide is also used in soap for its disinfecting quality. by the way, maybe someone can help me with this. i visited some fair trade garments (cotton/silk) and handmade paper (jute) producers in bangladesh and they would like to know how they can set-up a waste water treatment for the dyed water they throw-away after coloring their materials. they use azo-free synthetic and natural dyes. solution has to be low cost though because they are just small producers. thanks.
