Hardness/ Salinity Reduction
Hardness in water is defined as the amount of dissolved calcium and magnesium. Hard water is high in dissolved minerals, both calcium and magnesium.
Removal of calcium sulfate and other low solubility sulfates is very difficult for reverse osmosis system as the precipitate causes significant fouling. Expensive pre-treatment operations are needed to remove in order to allow proper desalination to occur.
The RDI™ Desalination System offers a cost-effective alternative to conventional technologies for treating this water as the system can tolerate high levels of these sulfates without pre-treatment.
