Figure 2 - SANURIL Tablets <br />Model 1000 <br />The Model 1000 or 1001 is one of simple design with no <br />moving parts_ It is manufactured of low linear, medium <br />density, UV stabilized polyethylene for durability and <br />resistance to corrosion. Each feeder is equipped with <br />four removable PVC feed tubes in which the charge of <br />SANURIL tablets is contained. (See Fig. 3 ) The tubes <br />are inserted down through the removable top cover of <br />the feeder into the stream of wastewater. The lower end <br />of each tube is slotted to permit free flow of water <br />through the tubes to assure good contact between the <br />water and SANURIL tablets. <br />TOP COVER <br />HOUSING <br />SLOTS <br />WEATHERPROOF CAP <br />Figure 3 - Model 1000 <br />Feed Tube Removed <br />The Model 1000 or 1001 is furnished with a selection of <br />weir plates, with weirs ranging in size from 1 to 3 inches <br />in width, for insertion at the outlet end to control the inter- <br />nal water level, depending upon plant capacity and the <br />residual chlorine required. (See Fig. 4) The feed tubes <br />have been precisely located in a diamond shaped pat- <br />tern, a baffle is installed at the inlet end and the outlet <br />end is contoured for proper water velocity and flow direc- <br />tion. <br />TOP COVER <br />WEIR PLATE <br />Figure 4 <br />Cover Removed Showing Weir Plate and Baffle <br />The entire Model 1000 or 1001 assembly is compact and <br />easy to handle, measuring 26 inches long, 18 inches <br />wide and 16 inches deep.

Engineering <br />drawings of Model 1000 or 1001 are shown in <br />Appendix B. <br />Installing the Model 1000 <br />The Model 1000 or 1001 is designed for installation in <br />any sewage treatment plant having sufficient space to <br />permit proper mounting. The unit can be located in or <br />preceding the chlorine contact tank as close as possible <br />to the inlet so that the entire plant flow of wastewater can <br />be channeled through the unit before it enters the chlo- <br />rine contact tank.
