Water softening removes calcium and magnesium ions that cause water hardness using ion exchange technology.How Water Softening WorksHard water passes through resin beads that exchange sodium ions for calcium and magnesium ions.ApplicationsBoiler feed waterCooling towersLaundry and textileFood and beverageRegeneration ProcessSalt (NaCl) solution regenerates the resin, restoring its softening capacity.Contact UsEmail:...

The activated sludge process is a common biological wastewater treatment method using aeration and sedimentation.How It WorksWastewater is mixed with biomass (activated sludge) and aerated. Microorganisms consume organic pollutants, then the mixture settles to separate treated water from sludge.Process TypesConventional activated sludgeExtended aerationContact stabilizationSequencing batch reactor (SBR)Get Equipment QuoteEmail: sale@yixingenviroequipment.com
