Wash-iT PRO - Brain image.jpg
Some time ago, there was someone asking to understand the 'brains' inside the Wash-iT PRO ...
At the time, I thought it was superfluous knowledge after all,
WISDOM is not what you know ! - that is called KNOWLEDGE
WISDOM is, of all you know, knowing what NOT to say !
This is why guru's and life coaches are so valuable - they use but a few words to lead a person to the salient point that solves the problem ...
That said, lately, I have been noticing more in depth probing .. a trend where people are digging below the surface knowledge and getting the science behind the equipment (some, not all) ..
So .. here it is .. the BRAINS in the Wash-iT PRO explained !
Firstly, in relation to the 'brains' of the Wash-iT PRO, there are two variables we have no control over on the work site :
1 Feed Water Pressure and
2 Input Water Temperature (unless we have a water heater)
These two variables will always cause the ratio of waste water to pure water to vary both up, and down, but neither will have any significant effect on the overall life of the RO Membrane.
The flow regulator in the Wash-iT PRO is a dynamic device which acts smart. A simple yet brilliant design,it's an o-ring in a housing with outlet holes partially covered by the o-ring. As pressure increases, the o-ring collapses incrementally to cover more areas of the holes, causing it to restrict the flow as needed to maintain the same rate.

Now to truly understand this, you have to know that there are systems out there with no brains .. intentionally leaving the adjustment of the RO to a completely under informed operator who can damage the RO and shorten it's working life. This is the manual valve with a 1/16" hole drilled in it - it's true .. open your RHG valve and have a little look ...
This method is called the 'orifice method' (sounds somewhat biblical .. but that is neither here or there)
The orifice method adds another variable to the system in that the flow rate does increase with the increased inlet water pressure, but it then also lowers the inlet water pressure on the membrane because its flowing more water, which then lowers permeate production. So - they tell you it is a good way to control the system but it is actually counterproductive.
In addition to this method being cheap - it just does not balance anything ...
