We managed to assemble the parts we bought!
With a makeshift water tank (our plastic container), we connected it to the water pump via a hose tubing that was secured using a hose clamp.
Using the mains power and the buck converter, we determined the power requirement for the pump to maintain appropriate pressure with water load.
It was found that the power requirement of the water pump is 12V and 6A. Maximum current the pump can operate within is 7.5A with 12V. Found out that current cannot be too low otherwise it won’t work or pump water through the RO membrane. Leaks in the system were troubleshooted and appropriate action was taken to tighten or to use sealing tape to stop leakages. For safety reasons, keep water away from power supply and electrical component should be insulated as appropriate.
Arrangement of the components needs to be optimised.
Need to find out if possible to lower power requirement of pump.
Flow rate needs to be adjusted by the RO membrane. Recommended 1:1 ratio between rejected water and filtered water.
Need to discuss how to test quality of water. Suggested using food colouring to illustrate functionality of water filter. To be done tomorrow.
