Fruit juices are traditionally processed thermally to avoid microorganisms’ growth and increase their shelf-life. The concentration of by thermal evaporation is carried out reduce volume consequently the storage transportation costs. However, many studies revealed that high-temperature operation destroys valuable nutrients aroma juice. Currently, membrane technology has emerged as an alternativ...

Interest in reuse of process water from the food industry has reinforced the importance of controlling and monitoring the effectiveness and reliability of treatment systems regarding removal of organic matter and microorganisms. The ability of adenosine triphosphate bioluminescence, conductivity, turbidometry, absorbance, and multichannel fluorescence spectroscopy for indirectly monitoring the ...

Wastewater produced by the crew members on a long-term space mission needs to be recovered as potable water. Reverse osmosis (RO) has long been in use as a physical membrane separation technology for wastewater treatment. However, membrane fouling and concentration polarization have limited the efficiency for high recovery reverse osmosis systems. An advanced high pressure rotating RO device wa...

Abstract Polyamide composite reverse osmosis (RO) membranes occupy an important position in water treatment. However, membrane fouling, especially biofouling, can lead to a significant decrease permeability. Therefore, reducing biological contamination is and property of RO membrane. In this article, hypothesis on the development new kind for antibacterial purposes was prepared by modification ...

Ethanol / Water Separation Technology is a long-term research. LTA molecular sieve, which an industrially important desiccant as kind of zeolite sieve. It always used in the reverse osmosis method, one seawater ddesalination, and extraction industrial ethanol method world. Membrane separation technology widely cell science, human microbial military industry, battery so on. With 2 years inventio...

Desalination and wastewater treatment technologies require an effective solution for brine management to ensure environmental sustainability, which is closely linked with efficient process operations, reduction of chemical dosages, valorization brines. Within the scope desalination reclamation, a circular system consisting seawater reverse osmosis (SWRO), membrane distillation (MD), forward (FO...

This paper presents some aspects of forward osmosis coupled with reverse osmosis using a recirculating draw solution, to produce desalinated water or for dewatering/concentrating a feed stream, with some data provided from a number of operational sites. Many of these aspects are applicable to other osmotic processes and provide an insight into where they may be appropriately considered. A compa...

We systematically assess the efficiency of chemical cleaning and report a simple but elegant approach to control scaling during membrane distillation (MD) of brine from reverse osmosis (RO) treatment of coal seam gas (CSG) produced water. Results reported here show that increased feed water salinity and the permeation of CO2 from the feed solution resulted in only a small and gradual decrease i...

The recent development in oil and gas industry increases the production and consumption of oil. The enormous amount of oily wastewater produced is urged to be treated to prevent humanity and environment from being threatened. Membrane technology is an appealing alternative for oily wastewater treatment due to its design simplicity, energy efficiency and environmentally benign approach. In this ...
