O - ya�' v"� �- <br /> Fax a Fax 4�1 <br /> 120 South Aurora Street vpgO <br /> Stockton, CA 95202 <br /> Dear Jeff, <br /> This letter is in response to your inquiry regarding the sludge produced as an end product <br /> of the Ink-Splitter wastewater treatment system, The Ink-Splitter was designed to produce <br /> not only sewer dischargeable effluent but also sludge which,when dewatered to landfill <br /> specifications, is not subject to discharge limitations. <br /> The sludge is produced by the Ink-Splitter through the three-step chemical process of <br /> precipitation,coagulation, and flocculation of the contaminants in your wastewater. The <br /> flocculation is achieved with the 4031 polymer, which encapsulates the contaminants and <br /> prevents these contaminants from leaching out of the sludge when disposed of in a <br /> landfill. The sludge will pass the Toxicity Characteristics Leachate Procedure (TCLP) <br /> test. This test, which is the one primarily used by landfill operators to determine <br /> suitability of proposed fill,involves submerging a sample of the sludge in a low pH <br /> aqueous solution for twenty-four hours,then filtering off the fluid and testing it for any <br /> restricted contaminants. Again,the encapsulating action of the polymer prevents <br /> contaminant release. <br /> I hope this helps to answer your questions on the nature of the sludge. Additionally, I am <br /> confident that among the files we received from rPS Printing Division we have copies of <br /> TCLP tests performed on the sludge produced in installations identical to yours. When <br /> these results are located I will fax them to your attention without delay. <br /> As always, feel free to contact me should you have further questions. <br /> Sincerely, <br /> Robert Madison <br />
