INITIAL QUESTIONS THAT NEED TO BE ANSWERED

The following questions are the product of a meeting with local Electrical Engineering Consultant, Dave Foye and  TE Instructor, Steve Johnston. The students in the Digital Electronics and Cisco classes at Logan HS will research the questions in an effort to find a solution to the design problem.

Date: 9.13.17

Discussion Topics/questions:

1.     What type of system/technology do we want to utilize? What questions do students have regarding these systems?

a.     Thermal systems- use energy to evaporate water and subsequently condense it again.

b.     Electrical, and pressure systems-some use cathodes and other use Reverse Osmosis which is a process in which dissolved inorganic solids (such as salts) are removed from a solution (such as water). This is accomplished by household water pressure pushing the tap water through a semipermeable membrane.

c.      The oldest method, thermal distillation, has been around for thousands of years. In thermal distillation, the water is boiled and then the steam is collected, leaving the salt behind.

d.     What technology is the lowest cost and least maintenance?

2.     Solar power:

a.     Can a PV panel supply enough electricity to power a pump separately.

b.     Can PV supply enough electricity to run a UV light to kill bacteria.

c.      Safety Concerns?

3.     Can a GameCam be used to transmit a still photo to monitor the pressure and flow rate of the device?

4.     UV Light:

a.     Can we run water slowly through a tube a set length with a UV light exposing it?

b.     What length does it need to be to kill bacteria?

c.      Is it better to pump or force water though a filter to purify it?

d.     Does this create increased pressures?

e.     Safety Concerns?

5.     Is it conceivable to create a low pressure distillery for desalination? Low Temperature also?

6.     How do we make this mobile and compact for ease of movement?
