in this report, experimental investigation of waste water treatment by reverse osmosis to enable its reuse in cooling tower is presented. a polyamide spiral wound ro membrane followed by three filters as ro pretreatment (two activated carbon and one cartridge filter) and samples of tehran refinery treated waste water have been used. the effect of operating conditions such as pressure difference...

V/ I do not know if there is any literature on the subject, and this is my excuse for publishing the results of a few observations made on the subject during the treatment of certain diseases. On the 2nd September, 1916, a patient was brought to the hospital 'with general anasarca. The case was diagnosed as one of Bright's disease. He was given the usual treatment of purgatives without effect. ...

Rapid increase in population and industrialization leads to huge generation of solid waste throughout the country with landfilling as the most common practice for management of these solid waste. It is estimated that out of 3267 MLD of sewage is generated in Delhi. Concentrations of COD, BOD5, heavy metals, NH4AN, low BOD5/COD ratio and the lack of nutrients in the methanogenic phase have restr...

The Forward Osmosis Brine Drying (FOBD) system is based on a technique called forward osmosis (FO). FO is a membrane-based process where the osmotic potential between brine and a salt solution is equalized by the movement of water from the brine to the salt solution. The FOBD system is composed of two main elements, the FO bag and the salt regeneration system. This paper discusses the results o...

The electro-osmosis-combined-preloading method is considered very promising in soft soil improvement, while the uncertainty function mechanism has hindered its practical application. To explore of combined method, experiments concerning single electro-osmosis and were carried out using reclaimed sludge. Macroscopic microscopic properties explored compared. Drainage, settlement, water content po...

Reverse osmosis (RO) is a ground breaking membrane based technology to purify water by separating the dissolved solids from feed stream resulting in permeate and reject stream for a wide arena of applications in domestic , industrial and wide array of applications. Reverse osmosis or other membrane separation processes has an innovative vision which is extremely targeted towards environmental p...
