  • Treatment of industrial wastewater

    All industries produce some type of waste product, either from production, maintanance or both. These hazardous and non-hazardous wastes need to be properly stored, treated and discharged to a sewer system or otherwise disposed of. Wastewater treatment is a multi-stage process to renew wastewater before it is discharged to the municipal sewer system. The goal is tio reduce or remove organic ...

  • Wastewater-Primary Treatment

    Primary Treatment is defined as a wastewater treatment process that takes place in a rectangular or circular tank and allows those substances in wastewater that readily settle or float to be separated from the water being treated. This process achieves solids separation. The solids readily available to settle to achieve sedimentation will do so in a settling tank referred as a clarifier. On the ...

  • Water and wastewater treatment for Solar industry

    Solar cells arc manufactured in a complex process thai requires enormous know-how. The objective is to produce panels with a high level of efficiency at low cost. To achieve this, different production processes are used. A fundamental distinction is made between solar cells on the basis of silicon wafers and thin-film cells, in which a special process is used to apply the photovoltaic layer onto ...

  • Wastewater treatment from phenol by AVS-100

    Qualitative treatment of wastewater from phenol and other organic contaminants has a great practical importance within different branches of industry. In many cases, contemporary ways of usage by enterprises do not provide high qualitative treatment (degree of phenol decline is 75-90%). These ways have defects such as long process duration from 3 to 5 hours, long processing time, high reagent ...

  • Treatment of slaughterhouse wastewater in upflow anaerobic sludge blanket reactor

    The performance of an upflow anaerobic sludge blanket (UASB) reactor operated at ambient temperature (20.9–25.2°C) was analysed for the treatment of slaughterhouse wastewater previously pre-treated for solid separation. The experimental work was carried out in a reactor with 15 L effective volume. Four organic loads were applied and the process performance was evaluated. The COD removal rate ...

  • Mixing To Enhance Facultative Wastewater Lagoon Treatment

    SolarBee® & GridBee® Are Leading The Way In most lagoons, sunlight causes a hard stratification at 12 to 18 inches of depth.  The top water is warmer and thick algae populations are producing supersaturated dissolved oxygen (DO).  The DO gasses off at the surface and is not readily available deeper in the pond for use by BOD-reducing bacteria. Meanwhile new ...

  • Effect of the pH influent conditions in fixed-film reactors for anaerobic thermophilic treatment of wine-distillery wastewater

    ABSTRACTIn anaerobic treatments, the pH conditions affect the efficacy and operation of the process. The main purpose of this research is to compare the effect of the pH influent on the performance of a high rate technology at laboratory scale, upflow anaerobic fixed-film reactor, treating distillery wastewater (wine vinasses) in thermophilic conditions. The results obtained shown that the pH ...

  • Assessment of treatment capabilities of Varthur Lake, Bangalore, India

    Manmade waterbodies have traditionally been used for domestic and irrigation purposes. Unplanned urbanisation and ad-hoc approaches have led to these waterbodies receiving untreated sewage. This enriches and eutrophies the waterbody. A physico-chemical and biological analysis of sewage-fed Varthur Lake in Bangalore was carried out and its treatment capabilities in terms of BOD removal, nutrient ...

  • Bio-desulfurization and denitrification by anaerobic-anoxic process for the treatment of wastewater from flue gas washing

    For amine-based carbon dioxide capture, nitrogen oxides and sulfur oxides were the main pollutants that had a negative effect on the regeneration of solvent. Before carbon dioxide capture, the sulfur oxides in flue gas should be removed by the method of calcium salt, and then washed by alkaline solution to eliminate the residual nitrogen oxides and sulfur oxides. The washing wastewater ...
