         25 . A system for treatment of hydrocarbon well fracture water, the system comprising:
 a multi-phase separator;   a manifold having an input port connected to an output of the multiphase separator and having multiple output ports;   a plurality of pipes, each having coils wound on the pipe, wherein each pipe has an input end connected to an output port of the manifold and each pipe has an output end;   a co-mingling manifold having input ports connected to the output ends of the plurality of pipes.   
     
     
         26 . A system as in  claim 25 , further comprising a proppant-water blender connected to an output of the co-mingling manifold. 
     
     
         27 . A system as in  claim 25 , wherein the multi-phase separator comprises a multi-stage separator. 
     
     
         28 . A system as in  claim 27 , wherein the multi-stage separator comprises a two-stage separator, wherein:
 a first stage of the two-stage separator comprises a three-phase separator and   a second stage of the two-stage separator comprises a two-phase separator.   
     
     
         29 . A system as in  claim 28 , wherein the three-phase separator comprises a four-material separator. 
     
     
         30 . A system as in  claim 29 , wherein the four-material separator comprises an oil-water interface control system.
