Reverse osmosis

GECOL and a consulting consortium of experts from ZSW, German Wind Energy Institute (DEWI) and Lahmeyer International (LI) are preparing the installation of an experimental plant for seawater reverse osmosis desalination powered from renewable energy sources (SWRO+RES) at Libya’s coast of the Medite

An efficient cost-effective batteryless photovoltaic-powered seawater reverse-osmosis desalination system is described. The system has a modest 2.4 kWp photovoltaic array and yet promises to deliver 3 m3/d throughout the year in an example location in Eritrea, operating from borehole seawater (at 40

Treatment and reuse of agricultural drainage water (ADW) is complicated by the presence of soluble organic and inorganic pollutants in addition to hazardous chemicals. Large-scale desalination systems for agricultural drainage water require the development of affordable pretreatment for removal of s

Kuwait needs to add more desalting units to its present installed capacity to satisfy the growing need of potable water. The energy consumed by different desalting system is one of the main parameters affecting the choice of new desalting system. Every desalting system consumed either thermal, or me

The wastes generated in the production of juice from citric fruits can become a great environmental problem if they are not managed correctly. Over the last years the European laws have become more restrictive about the pollution levels from industries. The environmental problem is directly related

The reverse osmosis (RO), as alternative to the chaptalization or vacuum evaporation, enables the must concentration if sugar concentration needs to be increased. The presented study shows the incidence of operating parameters of a RO industrial system to the quality of extracted water and to the en

Purification of phosphoric acid by reverse osmosis (RO) and nanofiltration (NF) was studied using different commercial membranes of common industrial use. Both techniques represent an interesting alternative in purifying industrial phosphoric acid solutions. RO is a good choice to purify solutions u

In the dairy industry non-accidental losses of milk or dairy products to sewer amount to 1–3% of the total milk processed. These significantly contribute to the 0.5–6.0 g COD/L of end-of-pipe waste-water. The major part of this polluting charge originates from starting, interrupting, and stopping da

RO seawater systems operating on a surface feed water, originating from an open intake source, require an extensive pretreatment process in order to control membrane fouling. Considerations of long-term membrane performance stability have lead to an initial design concept of operation of seawater RO

Reverse osmosis (RO) is an efficient process for the removal of ionic and organic pollutants from contaminated water. In this study, rotating RO, which takes advantage of Taylor-Couette flow instabilities to reduce the flux decline related to concentration polarization and membrane fouling, was inve
