Various approaches to solvent recovery have been studied for the manufacturing process of celecoxib, the active ingredient in Celebrex. A design case study has been performed by Rowan University with Pfizer through a green engineering partnership program. The manufacturing operation at Barceloneta, Puerto Rico was evaluated and several green engineering alternatives for the purification and rec...

A new water recovery system architecture designed to fulfill the National Aeronautics and Space Administration’s (NASA) Space Exploration Policy has been tested at the Marshall Space Flight Center (MSFC). This water recovery system architecture evolved from the current state-of-the-art system developed for the International Space Station (ISS). Through novel integration of proven technologies f...

Algal blooms are a frequent phenomenon in nearly all kinds of fresh water. Global warming and eutrophication by waste water, air pollution and fertilizers seem to lead to an increased frequency of occurrence. Many cyanobacteria produce hazardous and quite persistent toxins, which can contaminate the respective water bodies. This may limit the use of the raw water for many purposes. The purifica...

Introduction The production of scrap tires only in the EU, USA and Japan is around 6 million tones per year. As the associated automotive industries grow the huge quantity of waste tires presently produced in the world will certainly increase in the future [1]. Thus the disposal of scrap tires becomes a serious environmental problem. The production of activated carbons from solid wastes is one ...

background detergents and difficulties of their presence in the water and wastewater cause various problems such as foam production, anomalies in the growth of algae, and accumulation and dispersion in aqueous environments. objectives the aim of this study was to examine and compare the moving bed biofilm reactor with another reactor without media (carries) for anionic surfactants removal. mate...

Activated carbon filters play an important role in water filtration and purification from contaminants of different origin. Their limit consists in bacterial proliferation, which may occur only during prolonged periods of non-use and in their ability to remove radioactive contaminants present in waste water from Industry or Nuclear Medicine departments. In this work we tested a commercially ava...
