Today, the survival of process industries is increasingly dependent upon the environmental sustainability of their technologies. There is growing concern about the problems of waste minimization. Waste streams from various ...

A mathematical model for the prediction of performance of a bioprocess of gluconic acid production in an airlift bioreactor (ALBR) in a batch process has been developed. The model consists of a set of simultaneous first ...

There is hardly any chemical process, which does not involve separation of liquid mixtures or recovery of valuable components from the reaction products. Liquid-liquid extraction processes have been increasingly used with ...

The aim of this research is to study the treatment of 4-chlorophenol bearing wastewater by biological treatment in an SBR without any adsorbent (blank SBR) and an SBR loaded with Granular activated carbon (GAC-SBR). The ...

In 21St century, most of the countries including India are facing energy crisis due to accrued energy demand and decline in production of liquid and gaseous fuels. Most of the conventional oil and gas fields have already ...

Hydrogen is projected to be one of the primary energy sources in the 21st century. It has the highest specific energy content of all conventional fuels and is the most abundant element. The three main methods for producing ...

Wastewater treatment and re-use of industrial process water is a critical issue for the suitable development of human activities. The need for effective water recycling has reinforced the research on tailored low cost ...

Extracellular polymeric substances (EPS) are viewed as major fouling components during filtration of biological feeds in industry. However, very few studies investigated the fouling mechanisms of polysaccharides, one major ...

Synthetic dyes are used in the textile, food, paper, printing, drug, cosmetics and leather industries. Major classes of synthetic dyes including Azo, Anthraquinone dyes constitute more than 50% of those used in industrial ...

Paper industry consumes large amount of water and generate an equal amount of wastewater having high BOD, COD, pH, turbidity, high temperature, color etc. The environmental pollution problem for agro based paper mills is, ...
