How Reverse Osmosis Water Purification Systems Work
Reverse Osmosis is a process in which dissolved inorganic solids (such as salts) are removed from a solution (such as water). This is accomplished by household water pressure pushing the tap water through a semi permeable membrane.

Crude oil is most often produced as a water-in-oil emulsion containing large quantities of dissolved salts and suspended solids. Crude oil desalting is accomplished by mixing fresh water with the incoming crude to "wash" salts and solids from the crude.

The Nexus concept is the interconnection between the resources energy, water, food, land and climate. Such interconnections enable to address trade-offs and seek for synergies among them.

- What is hydrophobically modified polyacrylamide (hmpam)?
- Hydrophobically modified polyacrylamides (HMPAM) are an important type of associating polymers. One method to copolymerize acrylamide (AM) with a hydrophobic comonomer is a free radical micellar polymerization technique in which the hydrophobe is solubilized into micelles dispersed in a water continuous medium.
- How is acrylamide hydrophobically modified with dihexylacrylamide (hmpam) prepared?
- Polyacrylamides hydrophobically modified with a small amount of dihexylacrylamide (HMPAM) have been prepared by means of an aqueous micellar polymerization technique. This process leads to copolymers in which the hydrophobic molecules are randomly distributed as blocks in the acrylamide backbone.
- What are the associating copolymers?
- The associating copolymers are polyacrylamides hydrophobically modified with a low amount (1-1.5 mol%) of N,N-dihexylacrylamide (DiHexAM). They are obtained through a micellar radical copolymerization in water, with sodium dodecyl sulfate (SDS) as the surfactant and the potassium persulfate (K2S208) as the initiator.
- Does a hydrophobe affect a polymer-surfactant interaction?
- In previous studies on associating polymers-surfactant interactions, the hydrophobic character of the polymer was varied by modifying the content or the nature of the hydrophobic groups. The effect of the hydrophobe distri- bution at a constant hydrophobe level was not reported so far.
