Corn steep water as effluent which arrives in environment from starch processing industry has adverse effects on the environment and also large volume of fresh water is wasted. Corn step water is composed of high concentration of proteins, sugar, starch, vitamin and minerals, so it can be used as substrate for production of biological products. Hence, corn steep water concentration is important...

akin type (asymmetric) reverse osmosis membranes undergo an irreversible osmotic dehydration upon coming into contact (skin side) with salt solutions. the extent of consequent changes (in appearance; decrease in linear dimension, water flux and salt rejection) are dependent on the salt concentration. these observations are correlated with the expected morphological changes taking place during d...

Seawater desalination for agricultural irrigation will be an important contributor to satisfying growing water demands in water scarce regions. Irrigated agriculture for food production drives global water demands, which are expected to increase while available supplies are further diminished. Implementation of reverse osmosis, the current leading technology for seawater desalination, has been ...

TEAM 6 Consultants evaluated cooling tower and blowdown water treatment options, recommended a treatment method, and designed a reuse distribution system for irrigation at the Molasky Corporate Center to be leased by the Southern Nevada Water Authority (SNWA). Design parameters utilized to achieve irrigation water quality and quantity compatible with the building landscape design and acceptable...

background: the chemical quality of water used for dialysis fluid is a vital factor in the overall care received by dialysis patients. therefore, water used for this purpose should be treated with advanced methods before use for dialysis. the objective of this study was to assess the efficiency of reverse osmosis systems to improve water quality used for dialysis fluid. methods: in this descrip...

We present a method to produce anti-fouling reverse osmosis (RO) membranes that maintains the process and scalability of current RO membrane manufacturing. Utilizing perfluorophenyl azide (PFPA) photochemistry, commercial reverse osmosis membranes were dipped into an aqueous solution containing PFPA-terminated poly(ethyleneglycol) species and then exposed to ultraviolet light under ambient cond...

Photovoltaic based reverse osmosis desalination systems (PV/RO) present an effective method of water desalination especially in remote areas. The increase of the feed water temperature leads to an amelioration of the plant performances. Photovoltaic Thermal Collector (PV/T) represents an ideal power source as it provides both electric and thermal energies for the reverse osmosis process. Nevert...
