Challenges High Flow Chemical Dose Controller Spring 2011

The High Flow Dose Controller aims to provide AguaClara plants with a simple dose controller  that requires minimal input and oversight from the plant operator.  In keeping with AguaClara standards, this dose controller will not require the use of electricity, will be simple to understand and operate and will be constructed from robust components.  Additionally, the relationship between the driving head and flow rates within the dose controller must match the relationship between plant flow rates and water elevation in the entrance tank. The mechanism for metering flow in both the dose controller and the plant must therefore be the same and will be evaluated as part of the new dose controller design.  The High Flow Dose Controller will be designed for  flow rates where the Linear Dose Controller is unable to meet flow demands.
