Abstract:
A chemical feeding system for adding chemicals to an aqueous distribution system comprising:a vertically oriented cylindrical mixing chamber having a transparent or opaque tube with a cap on top connected by an effluent conduit to an adjustable flow meter valve;an end cap for said transparent tube having a flexible effluent drain tube with a shutoff valve leading to a main water pipeline;a tee connection mating with the end cap and having an effluent tube leading to said adjustable flow meter valve;a pipe system for said mixing chamber comprising:a first vertical inlet pipe connected to the main water pipeline;a first elbow connected to said first vertical inlet pipe;a shutoff valve inserted in a horizontal pipe connected to said first elbow at one end and to the tee connection;a second horizontal pipe connected to an outlet portion of the tee connection and a second elbow connected to the second horizontal pipe;a second vertical outlet pipe; anda one-way flow valve connected to short pipes at both ends to connect to said second elbow and to said main water pipeline; anda shutoff valve inserted in the main water pipeline between the first and second vertical outlet pipes;whereby a chemical additive is added to the mixing chamber for mixing and feeding the main water pipeline at a controlled rate by the flow meter valve.
