The water being treated has a TDS level of 4,000 - 7,000 mg/L. The specified target hardness level in the treated stream is <1ppm. in="" actual="" service="" the="" ion="" exchange="" softener="" is="" consistently="" producing="" water="" with="" a="" hardness="" level=""><0.5ppm. some="" novel="" aspects="" covered="" in="" the="" paper="" include="" the="" following:="" the="" use="" of="" an="" air="" scoured="" dual-media="" nutshell="" filter,="" the="" application="" of="" short="" bed="" ion="" exchange="" technology="" to="" the="" treatment="" of="" produced="" water,="" and="" an="" in-situ="" resin="" cleaning="">
