Three new slow sand filters were put into commission in August.
As a result of my investigations in Europe and America during 1920 and the early part of 1921, it was decided to order experimental rapid filters and sedimentation tanks capable of dealing with two million U.S. gallons per 24 hours, the necessary liquid chlorine controlling plant to deal with the whole of the company's output, also Booth's dry chemical] feeders to deal with all the necessary coagulant.
The rapid filters, ete., and liquid chlorine controlling apparatus arrived during November.
It was also decided to engage. the services of a member of Messrs. Wallace & Tiernan's staff to look after the erection and bringing into commission of this plant.
The liquid chlorine apparatus has now been put into commission with very satisfactory results, and it is hoped to start the experimental plant to work very shortly.
