The effect of surfactants upon spectrophotometric monitoring of the efficiency of removal of crude petroleum products from waste water by means of pressure-driven membrane processes

چکیده
In the presented research we have tested the application of photo ionization detector of ECOPROBE 5 analyzer to monitoring of low concentrations of petroleum products in water. Petroleum products are organic pollutants that are present in wastewater most frequently, which is caused by their broad applications and frequent incidents. Emergency leakage of petroleum and its products is predominantly caused by technical defects and operators’ mistakes during transport, handling and storage of petroleum products. We tested the application of the mobile analyzer ECOPROBE 5 (RS Dynamics, Prague), which measures concentrations of organic substances in gas phase. It is sufficiently sensitive even for determination of milligram amounts of petroleum products in one liter of water. This principle of measurement can serve, e.g., as a basis of emergency alarm during long-term operation of membrane technology. Key-words: Crude petroleum products, waste water, pressure-driven membrane processes

Art to use Electrospun Nanofbers/Nanofber Based Membrane in Waste Water Treatment, Chiral Separation and Desalination
The technique to fabricate nanofibrous mat by electro-spinning has been known for a long time. But the attempts to use the electospun nanofiber mats, also known as electro-spun nanofiber membranes (ENMs), for filtration purposes began only recently. Among many membrane filtration processes, air cleaning by the removal of dust particles has already been commercialized and the product has been in...
متن کاملRemoval of Manganese from an Aqueous Solution Using Micellar-Enhanced Ultrafiltration (MEUF) with SDS Surfactants
In the present study, micellar-enhanced ultrafiltration (MEUF) was used to remove manganese (Mn) (II) from synthetic wastewater. The effects of different operational conditions on the filtration performance of MEUF or the membrane were studied. It was found that the transmembrane pressure has a major influence on the permeate flux and an insignificant effect on the rejection coefficient. The pe...
