Although the present volume is devoted entirely to the disposal of sewage, it may be stated here that in the matter of sterilisation, the suggestions that have been made apply with equal force to drinking-water supplies. Where the water contains a considerable amount of matter in suspension, it would be advisable to provide means for ample storage and settlement before passing it through the sterilising plant.
Note.—An apparatus for the injection of chlorine solutions for the purpose of sterilising sewage effluents and drinking water has recently been brought out by the Candy Filter Co., Ltd., and has for some months been in practical operation, dealing with 200,000 gallons of river water per day for an important municipal waterworks in the country. In this case the installation includes a de-chlorinating process, and it is stated that the results of tests in actual work show that the sterilised water contains neither B. coli nor free chlorine.
