ABSTRACT:
A system is provided that includes: (a) a mobile platform; (b) an input pump operatively connected to be capable of pumping a treatment stream through the system; (c) a centrifugal separator operatively connected downstream of the input pump to centrifugally treat the treatment stream; (d) a borate filter operatively connected downstream of the centrifugal separator to filter the treatment stream capable of removing at least some of a borate when the treatment stream is at a pH of 8 or above; and (e) a chemical-additive subsystem operatively connected to be capable of: (i) selectively adding one or more chemical agents to the treatment stream upstream of the centrifugal separator, wherein the chemical agents can be selected to be capable of precipitating dissolved ions selected from the group consisting of: sulfate, calcium, strontium, or barium, magnesium, iron; and (ii) selectively adding a chemical agent to the treatment stream upstream of the borate filter to increase the pH of the treatment stream to 8 or above.
