CALIFORNIA 90032 <br /> (213) 221-9513 <br /> March 10 , 1978 <br /> ELECTRO-OSMOSIS <br /> A PROVEN SOIL ABSORPTION SEWAGE SYSTEM <br /> Introduction <br /> For the past 7 years a new method of securing soil <br /> .abso ption of wastewater in marginal , tight and nearly <br /> impe vious soils , has proven to be successful . The process , <br /> know as Electro-osmosis , was developed and patented by <br /> Mr. arl Peterson of Minneapolis . Working with Mr. Peterson, <br /> Mr. rank P. Coolbroth, founding President of the National <br /> On-S' te Sewage Treatment Association , Inc. , who operates <br /> Cool•roth-Sitton Septic Tanks , Inc. at Minneapolis has made <br /> over 40 successful installations in Minnesota and more in <br /> near by states . There are now in the United States a total <br /> of o er 180 successful systems installed under standards <br /> and licensing agreement with the patent holder. <br /> Defi ition, Theor and <br /> Back•round of Process <br /> The International Dictionary of Physics and <br /> Ele tronics says : "Electro-osmosis . . . : The movement of <br /> liq id with respect to a fixed solid . . . as a result of <br /> an pplied electric field. " <br /> McGraw Hills ' Encyclopedia of Science and Technology <br /> says : <br /> (A) Electro-osmosis was first observed by F. Reuss <br /> in 1809 . This investigator pushed two vertical glass <br /> cylinders into a mass of wet clay, filled the cylinders <br /> with water, and inserted metal electrodes . When an <br /> electrical potential was applied, the level of water rose <br /> at the negative , but fell at the positive pole to which <br /> the suspended clay particles were attracted. The results <br /> were in accord with the view that the clay particles <br /> were negative with respect to the water. Electro-osmosis <br /> has been applied to the removal of water from peat <br /> and moist clay. <br /> (B) Electro-osmotic Dewatering: A method of drying <br /> out an excavated area, used to increase the strength of <br /> the ground and permit tolerable excavation slopes .
