2. Total dissolved solids - Wikipedia

   en.wikipedia.org/wiki/Total_dissolved_solids

   Bottled mineral water usually contains higher TDS levels than tap water. Total dissolved solids (TDS) is a measure of the dissolved combined content of all inorganic and organic substances present in a liquid in molecular, ionized, or micro-granular (colloidal sol) suspended form. TDS are often measured in parts per million (ppm).

3. Electrodeionization - Wikipedia

   en.wikipedia.org/wiki/Electrodeionization

   Electrodeionization (EDI) is a water treatment technology that utilizes DC power, ion exchange membranes, and ion exchange resin to deionize water. EDI is typically employed as a polishing treatment following reverse osmosis (RO), and is used in the production of ultrapure water. It differs from other RO polishing methods, like chemically ...

4. Wastewater quality indicators - Wikipedia

   The mass of dried solids remaining on the filter is called total suspended solids (TSS) or nonfilterable residue. Settleable solids are measured as the visible volume accumulated at the bottom of an Imhoff cone after water has settled for one hour. [2]: 89–98 Turbidity is a measure of the light scattering ability of suspended matter in the water.

   This project enables the reduction of total dissolved solids from 1,000 mg/L to 250 mg/L and turbidity from 10 NTU to 1 NTU, a unit indicating the cloudiness of a fluid. The water recovery can reach 75%. Electrical energy consumption level is 1 kWh/m 3, and the cost for water treatment is 0.22 US dollars/m 3. Some other large-scale projects can ...
