s <br /> s+ , <br /> suspended mixture to achieve sedimentation separation. This sedimentation <br /> occurs within a short time, after which the clean water is drawn off using side <br /> taps, and the clean water is pumped over into Tank#4, the recycled water <br /> tank. After the clean water is decanted off the top of the sediment laden <br /> water, the bottom phase, is dropped off by gravity into a number of flat <br /> square concentration tanks for further clean water decanting and subsequent <br /> air drying of the flocked sediment. This sediment is semi-solid and is disposed <br /> in the proper designated landfill. Tank#3 is fit with mechanical level guage, <br /> and hi level electric warning devices as well. <br /> The flocculation procedure is performed whenever the quantity of dirty water <br /> warrants it being done. <br /> The clear water that is pumped over into Tank#4, is finally filtered using a <br /> pressure leaf filter and diatomateous earth pre-coat. This filter and pre-coat, <br /> will remove all the residual solids down to % micron size from the pressure <br /> pump make up water reservoir, tank#4. Swimming pool chlorine products <br /> rwill be used to control biological growth, and the monitoring of this chlorine <br /> level will be done daily using standard swimming pool equipment and criteria. <br /> The operation of tank #3 and #4 are active, rather than passive, as with the <br /> first part of the system. <br /> Although this simple system will not be state of the art technically, <br /> incorporating a lot of sophisticated electronic monitoring devices, it will work <br /> just as well and will be much more operationally and financially friendly. <br /> Once sufficient experience is earned ie. The number of daily washes needed to <br /> fulfill the requirements of the taco truck operators, the overall capacity of the <br /> system will be adjusted as required, and monitoring procedures as well. <br /> � I <br />
