TROUBLE SHOOTING Incorrect amounts of chlorine delivered may be due to several causes. Some of the potential problems and their remedies are outlined below. fficient Chlorine - If the chlorine is consistently too ,n the chlorine contact tank, use an additional feed tube or a smaller size weir. Samples taken at the effluent end of the unit can be used to determine whether suffi- cient chlorine is being delivered into the chlorine contact tank. If the feed tubes do not reach the bottom of the unit, insufficient chlorine will be released into the wastewater Check the feed tubes for contact with the bottom. If improperly loaded, the tablets can jam, causing the stack to remain suspended above the water level. This causes low dosage levels. Check to be sure that all the tablets are flat in the stack. Should there be a tablet jam, a hard rap on the tube will loosen the bound tablets. A gross hydraulic overload will cause a lower than desired chlorine residual. The Model 1000 or 1001 has been designed to accommodate 100 to 200% over aver- age flow. This may be exceeded temporarily by abnormal conditions such as heavy rains etc., and nothing should be changed if this is the case. However, if the overload into the plant becomes permanent due to the influent from additional sanitary installations from homes, busi- nes or other sources, the additional flow must be pensated by using a larger weir and/or more feed ;s to maintain the desired chlorine level. The neces- sary changes can be determined by recalculating the daily flow and using the tables and graphs to find the new required weir size and tube complement. Overchlorination - Overch lori nation is due to excessive consumption of disinfectant. The chlorine residual may be reduced by removing one or more feed tubes, adding spacers, and/or using a larger weir. Plugging - If the flow through the weir is restricted, the water level will rise and cause back-up in the unit. The most common obstacles are leaves and sticks or sewage solids. Remove these immediately whenever found. Under most conditions of flow, there is sufficient shearing action by the water to keep the slots in the feed tubes from becoming obstructed. If the slots become obstruct- ed, they may be cleared as described under MAINTE- NANCE or by removing the feed tubes from the unit feeder and clearing the obstructing materials by hand. HANDLING AND STORAGE SANURIL is an oxidizing agent. It should be stored in a cool, dry area away from oxidizable material such as rags, paper, kerosene or other combustible materials. Do not inhale container vapors. After use, reseal container to protect remaining material. In case of fire, apply liberal quantities of water. OTHER APPLICATIONS In addition to wastewater chlorination, the Model 1000 or 1001 Tablet Feeder can also be used for dechlorination, and the chlorination of drinking water. For dechlorination, the Model 1000 or 1001 is used in conjunction with the D-CHLOR'rm tablets. These tablets are a sodium sulfite based formulation also having compatible dimensions for use in the Model 1000 or 1001 Tablet Feeder. For drink- ing water chlorination, the Model 1000 or 1001 is used in conjunction with the AQUAWARDI chlorinating tablets. The AQUAWARD" tablets are a calcium hypochlorite based formulation also having dimensions compatible for use in the Model 1000 or 1001 Tablet Feeder. This sys- tem is ideal for open channel flow operation and/or remote installations where other methods of disinfection are not practical or economical.
