pharmaceutical wastewater treatment using subcritical and supercritical water technology

Separation of Pharmaceutical Enantiomers using Supercritical Fluid Technology

The use of supercritical fluids as chromatographic mobile phases provides rapid separations with high efficiency, favoring their use in enantioselective separations. Supercritical fluid technology (SFC) is a versatile tool in the purification, enantioseparation and large-scale production of enantiomers of pharmaceuticals over comparable liquid chromatographic methods and is gaining popularity i...

Preparation of Pharmaceutical Powders using Supercritical Fluid Technology

application of ultrasonic technology for water and wastewater treatment

ultrasonic technology as an innovative technology may be used for water and wastewater treatment for pollution removal. this technology acts as an advanced oxidation process. application of this technology leads to the decomposition of many com­plex organic compounds to much simpler compounds during physical and chemical compounds during cavitation proc­ess. in this article review, some applica...

Evaluation of the Treatment of Pharmaceutical Industry Wastewater Using Chemical and Biological Methods (Case Study: Treatment of Wastewater Produced by Production of Methadone and Capecitabine)

Background & objectives: Pharmaceutical wastewater contains high concentrations of organic matter, high salt and difficult biodegradability, so it must be treated before discharge to the environment. In this study, it is aimed to evaluate the treatment of pharmaceutical wastewater (methadone feedstock and neutralized capecitabine) using chemical and biological methods. Methods: The laboratory ...

Non-Catalytic Subcritical Wet Oxidation of a Wastewater Treatment Sludge

Among the treatment and conversion technologies used for organic solid waste, wet oxidation has become an important process due to the fascinating characteristics of water as a reaction medium at elevated temperatures and pressure. Wet oxidation is able to degrade and remove organic compounds and thus reduce the mass and volume of solid wastes. Recovering valuable compounds and enhancement of a...

Supercritical Fluid Technology: Nascent Contrivance for Pharmaceutical Product Development

A supercritical fluid (SF) can be defined as a dense non condensable fluid. A fluid reaches the supercritical status when its temperature and pressure exceed the relevant critical temperature and pressure. At the critical point only a single phase exists which has some properties typical of liquids (density) and some of gases (viscosity, compressibility, and mass diffusion coefficient). For pha...
