Operators in Honduras have expressed a preference in operating the earlier-style Linear Dose Controller (LDC) over the Non-Linear Dose Controller designed during the Fall of 2009. The LDC is an elegantly simple design that requires minimal input and oversight from the operator. The , however, the LDC looses its elegance as plant flow rate increase. A new style of dose controller that can operate at high plant flow rates will be evaluated this semesterhas been designed.
This new dose controller uses a specialized ball valve as the metering device for the coagulant. Additionally, plant flow rate is measured through the High Flow Orifice Meter (HFOM). Together, these components make up the High Flow Dose Controller (HFDC)and provide AguaClara with the means to dramatically increase plant size.
