Totaux solides dissousLe total des solides dissous (TDS) est une mesure de la teneur combinée dissoute de toutes les substances inorganiques et organiques présentes dans un liquide sous forme moléculaire , ionisée ou microgranulaire (sol colloïdal) en suspension. Les TDS sont souvent mesurés en parties par million (ppm). Le TDS dans l'eau peut être mesuré à l'aide d'un compteur numérique. (Wikipedia)Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Serious environmental concerns are being raised with respect to at high Total Dissolved Solids (TDS) contents in spent leather processing liquors. Pickling alone contributes about 35% TDS in the effluents. As cost effective treatments for TDS are not yet available, in-plant control has become a necessity. In the present work, a picklefree chrome tanning method has been coupled with in-situ neutralisation of acid generated during the hydrolysis of chrome salts. The elimination of pickling has given a significant reduction in TDS. Higher uptake and more uniform distribution of chromium in the leather are other benefits of the process. Chemical, physical and microscopical analyses indicate that the leathers’ properties are comparable with those of conventionally processed leathers. It is believed that this new approach could be gainfully employed to overcome the twin concerns of TDS and chromium in the effluent. Note de contenu : - MATERIALS AND METHODS

It is necessary for the protection as well as for the aesthetic appeal of the products. It is also a well-known fact that this process has a substantial envi ronmental impact.
Many technologies have evolved to restrict the impact on environment of spray painting. These technologies focus on restricting the pollution during painting, as well as on the collection & treatment of the post painting waste viz. paint sludge. This article talks about the new technology to effectively collect and treat the paint sludge in order to keep the environnent clean, in the most cost effective manner.
Not many like to talk about paint sludge. It is still considered a menace and, at times, simply disregarded. Unfortunately, this does not solve the problem of removing the sludge effectively and disposing it in the best possible manner that has minimum impact on the environment.
Presently, the rules are getting stringent and it is the responsibility of the one who creates the sludge, to collect it and hand it over to government appointed agencies for an environment friendly disposal. This may sound simple, but the daily "collection" of a relatively difficult-to-handle sticky mass, in the most environment friendly and cost effective manner is surely a challenging task !
In order to understand the state-of-art technology and equipment developed for the paint sludge removal, it is important to list down the major considerations, based on which efficient sludge collection systems are designed.Note de contenu : - a. Type of paints used

Pollution -- Lutte contreIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : The traditional method for bovine hide preservation requires approximately 40-50% sodium chloride on raw hide weight or 95% saturated brine solution in case of wet salting. This salt resides in wastewater after the soaking process and generates a huge environmental pollution in the form of total dissolved solids (TDS) and chlorides (Cl-) during leather processing. The current research has developed antiseptic based hide curing formulation using 45% saturated brine solution which reduces 50% salt usage in compare to traditional method. The newly developed formulations have been found more effective in limiting microbial growth on cured hide than the conventional method preserving the bovine hide for more than 30 days. In this study, post-leather analysis e.g. grain pattern, scanning electron microscopic images, mechanical properties and organoleptic evaluation reveal that the crust leather produced from alternatively cured hides are comparable to the control obtained from traditionally preserved hide. The efficacy of the alternative system is also assessed by monitoring the environmental impacts caused by the leather processing effluents on the basis of TDS and chloride content, total solids (TS), total aerobic bacterial counts in soaking liquor, Bio-Chemical oxygen demand (BOD) and Chemical oxygen demand (COD). The environmental advantages of the alternative hide curing method are determined particularly by 50% reduction of TDS and chloride content. Therefore, this new method is feasible and industrially preferable to the traditional hide curing process.
