During the half century of development from a laboratory discovery to plants capable of producing up to half a million tons of desalinated seawater per day, Reverse Osmosis (RO) technology has undergone rapid transition. This transition process has caused signification transformation and consolidation in membrane chemistry, module design, and RO plant configuration and operation. From the early...

The concept of a small f- subm was presented in previous study. This work introduced hollow module, where module is said to be fuzzy when every it subm. Some new types modules are provided namely, Loc- as strength the but converse not true. Many properties and characterizations these concepts proved, also relationship between all researched. important results that explain this demonstrated seve...

Polyvinylidine fluoride (PVDF) hollow fiber and nanofibrous membranes are engineered and successfully fabricated using dry-jet wet spinning and electrospinning techniques, respectively. Fabricated membranes are characterized for their morphology, average pore size, pore size distribution, nanofiber diameter distribution, thickness and water contact angle. Direct contact membrane distillation (D...

Vapor absorption refrigeration system efficiently could be driven by the low grade renewable heat associated with the exhaust gas from the car engine, and uses the eco-friendly refrigerant, i.e. water. The absorption cycle, however, has not yet obtained much attraction in the automobile application due to its large volume and weight per unit of cooling capacity, which has limited to use. A micr...

As the number of leaking underground fuel tank sites with MTBE contamination continues to grow, there is a need to develop cost-effective solutions for treatment of soil and water contamination. MTBE poses special challenges due to its physicochemical properties, in particular high solubility and low Henry’s constant, low affinity for sorption, and very slow rate of microbial degradation. Advan...
