Thanks for this video! Gotta love RU-vid UNIVERSITY where you can learn literally anything! I was struggling with how to wire my permeate pump so thanks for this video!!!
According to the Instructions, The flow restrictor is to be installed before the permeate pump on the brine in line. Not after this is the same permeate pump I have Aqua Tec ERP-1000, if you install it as shown in video Pump will not click, clicking sound is important that means pump is working.
I dont have a flow restrictor in my home master and it works. However, I have been researching since my inlet water pressure is 60 psi and at my tank is 18 PSI ish. Maybe I do need a flow restrictor to increase pressure and/or replace the membrane as well
My understanding is the permeate pump system will not have the ASO auto shut off valve and that increases pressure, so the ASO system may only have 40psi in the tank if the source water is 60psi, but with the permeate pump the tank will achieve system pressure and you'd have a full 60psi going to your faucet and it will make clean water faster.
Two things done wrong here, flow restrictor should be before the permeate pump, not after. Second, automatic shut off valve should be before the pump (not after) or removed completely.
Why is that wrong? Does it damage anything doing it the way they did it? Is the other way more efficient or does it pump the water faster? Does it damage the pump? Sorry for all the questions but I am curious why it's wrong.
ASO is ok after the permeate pump, you want dont want it to be cycling forever. When you reach x amount pressure above your incoming water will close the inlet water. The only problem could be that if you are not using the RO you can create more TDS at the membrane and that TDS will potentially be stored at your tank. Flow restrictor is not needed if your inlet pressure is 60psi or higher but if you add a booster pump then you needed otherwise will never create the pressure at the membrane
According to a manual about all about ro systems that connection its wrong Anybody out there knows what flow retractor should I use for a p.pump 500 model with a 36 gpd membrane? I had the the problem the membranes clogging up (I'm using the yellow chip fr estrictors...its that the problem?
Super erklärt vielen Dank, wie ist das, wenn man anstatt eine mechanische permeatpumpe einen elektrischen pumpe benutz? Spart man dadurch noch mehr Abwasser?
Super explains, thank you very much, how is it when you use an electric pump instead of a mechanical permeate pump? Does this save even more wastewater?
It would give you more pressure in the product water tank if you add an electric pump but it would not make a major difference to the wastewater with a permeate pump. If it is without a permeate pump then the electric pump helps lower the wastewater but not nearly to the extent that the permeate pump does.
Do not use ASO if you use permeate. Its better to think about permeate pump as "smart (pumping) ASO". Permeate pump will shut off output tube by itself, once flow in permeate stops, and do this at very end instead of proportionally (like normal ASO). If you connect permeate pump together with ASO, there will be conflict: ASO as usual tries to block main input based on pressure in filtered water channel (permeate) - thus choking the performance (=time) when tank fills up, which leads to degrade in permeate pump performance - both in time and power, thus degrading filtering performance towards the end as well - cause it uses the power of waste/drain flow. So there is still large window for efficiency and filtering speed! Still, even with the parasitic effect of ASO, the difference is great. Thank you for the test!
@@ralphm6234 I recommend two technologies - either direct connection to membrane with minimal prefilters (2) or install 24v pump and wire it so that when you turn on trigger an electronic input valve (solenoid) opens and pump is enabled. The second system is much more complex and expensive, but has automatic operation and allows connecting two membranes sequentially or using side-stream membrane. Instead of using pressure-based shutoff (high pressure sensor). This creates a pressure-less system, minimizing leaks. Additionally, one can wire two-clock relay and add another solenoid to flushing segment (pressure bypass), and wire them parallel to first scheme, separating them with shotky diode - this allows automatic programmable membrane flushing. Both systems are direct flow (tankless). I gave away using tanks as they contaminate water. The permeate pump problem is that it requires to stay under pressure to function and when leaks - there is a disaster. I recommend only pressureless systems.
Hi, Unfortunately we don't stock it any more so i haven't got one to look at the diagram. However you can basically replace the 4 way valve with it and its ports are labeled on the unit.
