A device and method for the treatment of fluids using electrostatic fiel ds generated by a high voltage electric current, which reduces or eliminates calcification, scaling and microbiological contamination. A high voltage DC current is applied to a core electrode, generating an electrostatic field which traverses a dielectr ic sleeve surrounding the core electrode and charges the exterior surface of the dielectric sleeve, charging inorganic particles and, in the case of a biological contaminant such as bacteria, killing the organism. Fluid flowing through the device is agitated by a combination of spiral vane sections surrounding the dielectric sleeve and helical baffle sections lining the housing wall. Charged inorganic particles coalesc e into spherical aggregates which resist adhesion to pipes and vessels and can be filtered by techniques such as reverse osmosis without deteriorating the filter membrane . The device can thus be used to pre-treat water so as to enhance the performance and durability of purification systems such as reverse osmosis filtration system s.
