  • Features of Reverse Osmosis (RO)

    1. Removal of dissolved salts  Reverse osmosis can stably and effectively remove dissolved salts, dissolved organic substances (trihalomethane, its precursors, agricultural chemicals, etc.), and micro fine particles (living germs, dead germs, and many other micro fine particles) from water. Thus it is ideal for a wide area of applications ranging from production of ultra pure water to ...

This article is intended to increase your understanding of the machine and how it ...


  • Water recovery from sewage using forward osmosis

    This research is part of the Sewer Mining project aimed at developing a new technological concept by extracting water from sewage by means of forward osmosis (FO). FO, in combination with a reconcentration system, e.g. reverse osmosis (RO) is used to recover high-quality water. Furthermore, the subsequent concentrated sewage (containing an inherent energy content) can be converted into a ...

  • Reverse Osmosis: How Does It Figure Into a Dialysis Water System?

    Better than 95% of all dialysis centers use water purification equipment to purify water for dialysis. The centerpiece of these water purification systems has become reverse osmosis. In conjunction with sound pretreatment, RO has proven itself to be the safest, most reliable, and most economical method of purifying water for dialysis. Water plays an important, life-sustaining role for dialysis ...

  • Optimization and economic analysis for a small scale nanofiltration and reverse osmosis water desalination system

    This paper presents the results of a techno-economic investigation of a nanofiltration (NF) and reverse osmosis (RO) process for treating brackish water. Optimization experiments of six commercially available small scale RO and NF membranes were carried out using formulated artificial groundwater. A predictive model was developed by using response surface methodology (RSM) for optimization of ...

  • Application of Membrane Technology for the Recovery and Reuse of Water

    Abstract As water and sewer costs are expected to increase over the next decade, membrane technology will continue to be a viable and economical option in the recovery and reuse of water. This paper describes the mechanism of membrane effected separation (specifically reverse osmosis, ultrafiltration and microfiltration), membranes commercially available, membrane element configurations, and how ...


  • Application of forward osmosis membrane technology for oil sands process-affected water desalination

    The extraction process used to obtain bitumen from the oil sands produces large volumes of oil sands process-affected water (OSPW). As a newly emerging desalination technology, forward osmosis (FO) has shown great promise in saving electrical power requirements, increasing water recovery, and minimizing brine discharge. With the support of this funding, a FO system was constructed using a ...

  • Designed for a Challenge – New Dow Product Line Helps Maximize Industrial Water Recovery, Minimize Waste

    Cost of water on the front end and discharge fees on the other end are squeezing industrial water users. Increasing water efficiency is a clear solution but facilities reusing and recycling must now treat water that is more fouled and more expensive to treat. To help alleviate these challenges in the market, Dow Water & Process Solutions, a business unit of The Dow Chemical Company (NYSE: ...

  • Achieving Stringent Effluent Limits Takes a Lot of Energy!

    Enforcement of increasingly stringent effluent limits, and application of more sophisticated treatment processes for reduction of chemicals of potential concern, increases the energy consumed in municipal wastewater treatment processes. Energy consumption factors (ECFs) have been developed for wastewater treatment plant configurations based on the quantity of electrical energy used per cubic ...
