An activated carbon as adsorbent is derived from waste tendu leaves (Diospyros melanoxylon) from local Beedi (Cigarette) industry for removal of sulphur dye from textile waste water. Tendue leaves were chemically treated with sulphuric acid and activated carbon prepared was analyzed by pH, moisture content, ash content, bulk density and BET surface area. The adsorption studies were performed as...

In Estonia there is the largest industrially-used oil-shale basin in the world. This review addresses the environmental hazard of the waste streams of oilshale industry via solid wasteand water-path, mainly focusing on ecotoxicological risk due to open semicoke deposition inducing hazard to surrounding soils and groundwater. This is the first comprehensive ecotoxicological review of available d...

In any dairy plant, the quantity and characteristics of effluent is depending upon the extent of production activities, pasteurization of several milk products. The anaerobic digesters are used in the first phase of treatment, which is followed by high rate aerobic treatment. It remains as the most common effluent treatment scheme for dairy plants. The Indian dairy industry is stated to have th...

Electroless nickel plating is a widely used plating method in many industries. The usability of the coating is, however, restricted by the control problems related to the electroless nickel plating process. To ensure deposit quality, the transcendent properties of electroless nickel deposit should be accurately controlled during plating, which is challenging because of the spontaneous, unstable...

Textile industry is one of the most common and essential sector in the world. The textile industry consumes large quantities of water at its different steps of dyeing and finishing, among other processes. The non-biodegradable nature of dyes and their stability toward light and oxidizing agents complicate the selection of a suitable method for their removal. Moreover, toxicity bioassays have de...

When distilled water from a tin-lined still served as the plating diluent, cells of Aerobacter aerogenes developed symptoms of metabolic injury as evidenced by increased counts on supplemented, as compared with minimal, plating medium. Cysteine was as effective as yeast extract as a supplement to the minimal medium in increasing the viable count. Mg(++) and, to a lesser extent, phosphate buffer...

Waste metals in the form of metal oxide (hydroxide) sludges are generated in significant amounts by the metal finishing industries, and their accumulations pose problems for disposal and challenges for recycle. The availability of technically feasible efficient separations of metals such as nickel, cobalt, chromium, cadmium, copper, tin, zinc, lead, manganese, molybdenum, and titanium from plat...

Activated carbons are extremely versatile adsorbents for major industrial significance, especially for metal ions recovery from wastewaters. In this study, the activated carbon <span style="font-size: ...
