Kinetico Aeration System with Venturi Injector for Iron Manganese Removal 41-30

Kinetico Aeration Venturi System

The Kinetico Aerator is one method for removal of iron, manganese and hydrogen sulphide. Air is introduced into the water stream, promoting oxidation. Oxidation converts soluble iron and manganese to insoluble compounds, which precipitate out and collect in the bottom of the tank and/or are removed by an appropriate filter downstream.

Application

The Kinetico Aerator uses a 13” x 54” tank with a special top closure to hold a vent pipe and service flow riser tube. In high flow rate applications, it may be necessary to use multiple units in parallel. The maximum flow rate supported is 8 gpm for each Aerator.

There are two methods available for putting air into the system: 1) a venturi, where air is drawn in by passing the water through a venturi, or 2) an air pump where air is forced into the water stream.

The venturi requires a minimum pump flow rate of 5 gpm and should not be used with a jet pump (a jet pump usually pumps below 5 gpm). An air pump has no limits on flow rate from the well pump and may be used with jet pumps.

It is recommended that a drain/flush valve be installed at the bottom of the reactor tank to periodically allow the flushing of precipitated particles.

Operation

Water enters the reaction tank through the water inlet.

As water is pumped into the reaction tank, air is mixed with the water stream by the venturi. Oxidation occurs in the reaction tank, and insoluble oxidised compounds precipitate out.

The air vent has two purposes: 1) to vent excess air and hydrogen sulphide gas, and 2) to allow an air pocket at the top of the tank to help with the oxidation process.

Water is drawn up through the service flow riser tube and out through the water outlet.

Iron & Manganese Removal

The Macrolite® system can be used after the Kinetico Aeration system on water that has higher levels of iron & manganese. The aeration will accelerate the oxidation and conversion of iron into ferrous iron which the Macrolite® filter can capture and then backflush to waste. Certain water conditions are required so please contact us prior to purchase. A water analysis is recommended.
