Adsorption of Phosphonate Antiscalant from Reverse Osmosis .

Aug 08, 2012 · It is also demonstrated that NTMP is preferentially adsorbed over sulfate by GFH at pH 7.85. The presence of calcium causes a transformation in the equilibrium adsorption isotherm from a Langmuir type to a Freundlich type with much higher adsorption capacities. Furthermore, calcium also increases the rate of adsorption substantially.

Berkey vs. Reverse Osmosis Water Filtration

Finding clean, healthy, purified water can be harder than it sounds. Let us examine the positive and negatives of one of the more popular water purifying treatments around today, the Reverse Osmosis water filter system, or RO for short. Reverse Osmosis is the process of forcing water across a semi-permeable membrane using a high-pressure pump.

Adsorption - Wikipedia

Adsorption is the adhesion of atoms, ions or molecules from a gas, liquid or dissolved solid to a surface. This process creates a film of the adsorbate on the surface of the adsorbent.This process differs from absorption, in which a fluid (the absorbate) is dissolved by or permeates a liquid or solid (the absorbent), respectively. Adsorption is a surface phenomenon, while absorption involves .
