- Description
- INTRODUCTION:
We are environmental enthusiasts who are studying water quality. We are using electronic sensors and probes readily available in the market to study the properties of water and its behavior when exposed to different contaminants and sanitizing chemicals. Currently we are facing few chemistry issues dealing with our water analysis.
CHALLENGES FACED:
- Converting ORP reading from the probes in millivolts to Free Chlorine (FC) represented in PPM.
- Find the Total Chlorine (TC) and Combined Chlorine (CC) once the FC is identified.
- Finding Calcium Hardness
OUR UNDERSTANDING:
- Upon research, we were able to get a basic understanding of the topic for ORP reading to FC representation in ppm. We've been mainly dependent on Nernst equation to gather this information; is this the right approach or are there other methods?
- To find Total and Combined Chlorine, again upon research, we came to a clarification that this data can be gathered from Chlorine and Chloramination curve but we are not sure about the approach. Are there other solutions for this?
INSTRUMENTS USED:
- ORP Probe
- pH Probe
- EC (Electrical Conductivity) Probe
- Temperature Probe
ASSIGNMENT:
1. ORP to ppm conversion for Free Chlorine using an equation
2. Deriving Total Chlorine and Combined Chlorine values using data points collected from the probes and equations
3. Find Calcium Hardness value
4. Although accuracy is appreciated and should be the target, extrapolated values in some scenarios might be acceptable depending on the input factors and example test cases. This would only be if all other avenues are explored.
5. Don't reinvent the wheel - find and use existing equations if possible
DELIVERABLES:
1. All necessary equations (with multiple examples in Excel), graphs / charts, and data tables (also in Excel).
2. Deliver results at your earliest convenience - ideally within 2 to 4 weeks from start date
3. Be available over email, WhatsApp, Telegram, Zoom, Skype, or similar - communication is paramount
*If necessary, more details can be provided after an NDA is signed.
