Electrodialysis
Function:
(1) Realize the desalination, concentration and desalination process of materials and wastewater;
(2) Efficient inorganic salt concentration can be achieved, up to 200g/L.
Application scope:
Lithium extraction from salt lakes, recovery of lithium elements from waste batteries, desalination of amino acids, sugars and other materials, zero discharge of wastewater, reuse of reclaimed water, concentration and desalination of materials, and pre concentration by evaporation.
Water inlet requirements for electrodialysis system
(1) Inlet water temperature: 5-35 ℃;
(2) Influent SS: ≤ 1mg/L;
(3) Iron ions<0.3mg, manganese ions<0.1mgL;
(4) Chromaticity: colorless or with a light transmittance greater than 80%;
(5) Free from post flocculation substances;
(6) It must not contain highly polar organic solvents (especially ketones and benzene ring substances, with a requirement of ≤ 0.1mgL), oils, fats, and surfactants (≤ 0.1mg), and must not contain strong oxidizing or reducing substances (ORP absolute value ≤ 200mV);
(7) The concentration of all substances in the concentrated water after ED concentration should not exceed 80% of its solubility or experimental concentration limit, such as the concentration of calcium sulfate in the concentrated water should not exceed 1.6g/L, to ensure that the concentrated water side is not blocked by precipitates;
(8) Extreme liquid requirement: COD<100mg/L; SS<1mg/L； Fluoride ions<2mg/L; Sodium hypochlorite concentration<0.5%.
