AguaClara / Fluoride_Gravity-DEPRECATED

Our goal is to fabricate a user-friendly gravity-powered fluoride removal system that will be used for research. We aim to make the system easily adjustable so that various parameters can be tested.

Inconsistent PACl flow rates between tests #19

Open KevinSarmiento opened 6 years ago

KevinSarmiento commented 6 years ago

We have been unable to replicate the PACl flow rates after each trial at the same heights. We have identified 3 possible reasons for this issues: 1) Different water levels in IV drip chamber 2) Air bubbles between the PACl constant head tank and the flocculator 3) Changes in the fluoride constant head tank level due to insensitivity of the float valve

The team has found a potential solution to the issue. We found that in order to prevent major changes between experiments we should set the PACl constant head tank to the zero mark and pinch the IV tubing closed. This prevents water from back flowing into the IV chamber from the rest of the system.
