Ideal biocide for the protection of architectural paints, a dream or reality / C. D. Joshi in PAINTINDIA, Vol. XLVII, N° 6 (06/1997)

[article]  inPAINTINDIA > Vol. XLVII, N° 6 (06/1997) . - p. 33-39 Titre : Ideal biocide for the protection of architectural paints, a dream or reality Type de document : texte imprimé Auteurs : C. D. Joshi, Auteur Année de publication : 1997 Article en page(s) : p. 33-39 Note générale : Bibliogr. Langues : Anglais (eng) Tags : Peinture  Bâtiment  Adjuvant  Biocide Index. décimale : 667.9 Revêtements et enduits Résumé : An ideal biocide for the preservation of all the surface coatings against microbial degradation, holds the key for the future business of architectural paints world wide. The most stringent specifications and conditions for the use of ecotoxic compounds, laid down by the regulatory authorities and the environment protection agencies of different countries, (western countries in particular), is bound to affect the free use of any new or existing biocides in architectural paints. In near future, India may also join them in restricting indiscriminate and inadequate use ofmany such toxic and environmentally unsafe biocides hitherto being used in paints as preservatives. Thus the architectural paint manufacturers in India should get on to the task of finding out a suitable replacement for the existing biocides through scientific evaluation under Indian climatic conditions. This will not only result in financial gains to the paint manufacturer through restricting losses during production, storage and replacements of fouled paint, but also, make the customer happy, that he is being served with long lasting and quality product.

Bioremediation : A novel approach to waste to waste treatment in surface coatings industry / R. J. Patil in PAINTINDIA, Vol. XLVII, N° 6 (06/1997)

[article]  inPAINTINDIA > Vol. XLVII, N° 6 (06/1997) . - p. 41-52 Titre : Bioremediation : A novel approach to waste to waste treatment in surface coatings industry Type de document : texte imprimé Auteurs : R. J. Patil, Auteur ; P. K. Kamath, Auteur Année de publication : 1997 Article en page(s) : p. 41-52 Note générale : Bibliogr. Langues : Anglais (eng) Tags : 'Industrie  peinture  vernis'  'Eau  usée  industrielle'  'Epuration  eau  usée'  biologique'  Biofiltre Index. décimale : 667.9 Revêtements et enduits Résumé : In recent times, bioremediation - a biological treatment process for industrial wastes has emerged as a preferred technology in the chemical industry, which has not been exploited to the extent required, by the surface coating industry. This paper attempts to explore bioremediation as a process to degrade wet paint sludge and for the clean up of hazardous solvent residues in liquid as well as gaseous forms. Towards meeting these objectives, five microbial cultures have been isolated by the enrichment and adaptation culture technique from the spray booth environs as well as from the composite soil sample collected from the environs of Rashtriya Chemicals and Fertilizers Plant, located in the near vicinity of Hindustan Petroleum Refinery in Mumbai. The genera of all the five cultures have been identified biochemically, of which, one is an yeast culture and the rest is bacteria. During enrichment, individual hydrocarbon solvents such as benzene/ethyl acetate/mineral turpentine/chloroform/ methyl iso butyl ketone/toluene/butyl cellosolve/triethylamine/xylene/methanol and petrol are used as carbon and energy sources employing Kazuyoshi et al, simple mineral salts medium to support microbial activity. As the clean up of complex sites require a host of microbial flora with metabolic and physiological diversity, the microflora from the booth water was bioaugmented with isolates from the RCF source. The proportion of the culture mix in the consortia played a significant role resulting in enhanced uptake of organic residues, thereby shortening the period of incubation. About 95-99% reduction in COD values were achieved with concomitant reduction in the levels of solvent odours from booth water. Wet paint sludge digestion by the consortia, though, was considerably slow. Significant degradative changes in polyester portion of the binder has been observed as compared to amino resin. Further experimentation on exposure of individual cultures to a host of solvents in vapour/gaseous form has yielded interesting results.
