On one side of the law, and I’ve got mostly chickens and ducks over here and I’ve got all ducks over here, what’s going to happen if I’ve got a fence in between those? Naturally the chickens are going to go to one side to equal out the amount, the amount of chickens and ducks on one side versus the other. They want to create equal on both sides. Naturally water is the same way in those cell walls. Water is going to want to. If I have 50 tvs, water over here and a 500 tds water over here, this more. This is going to want to push more pure water across that membrane, so I create a balance of equal amounts of concentration on both sides. Does that make sense? It wants to do that so much that it will actually force pressure and that these are already global’s. It’ll actually fourth pressure and push to where the other side has a higher level and volume. Then the lower concentration side and that force is called osmotic pressure, so reverse osmosis if that’s Oz Moses, and that’s osmotic pressure. Reverse Osmosis is I’m going to take this, the, the, this over here that has, if it’s 500 ppm milligrams per liter or whatever it happens to be, I’m going to take a pressure and push it the other way and push that water back across the membrane so that create lower concentration. Gds water on the other side, I’m going to reverse osmosis.
Speaker 1: 01:39
That creates energy. It requires energy. It requires some force. Did you that I am overcoming osmotic pressure, so I have to have some force to make that happen in a in where am I going to get that forest from
Speaker 1: 01:53
most of the time at home. The benefit of the municipal water supply is that they’re creating that forced for me. What’s typical line pressure for plumbing in this area for 70 PSI. Rusty. Okay, so 70 PSI. That’s where it’s coming from. It’s that line pressure from the city, that 70 psi that’s going to use to push water across that membrane. Okay, and what is the optimum psi for reverse the hospital at the moment? I don’t know the answer to that question. I’m sorry. Feel. I don’t know the optimum pressured. Um, what are your membranes testing you? Oh, our membranes are tested. Usually testing the standard and it’s kind of variable because it didn’t because I think manufacturers sorta have a, have a determination, but it’s usually between 55 and 65 psi. Is that window where they’re, they’re tested at. Ours are tested at 65. The Grl memories I’m gonna talk about are tested at 65 psi as an inlet pressure as far as what our production rates are and stuff. You’ll see some out there that’ll say six tests at 60 PSI. Um, I believe. I want to say I’ve seen some that have been tested at 55 psi,
Speaker 1: 03:08
but it’s nothing crazy. It’s not like, oh, it’s going to. You have to put 100 PSI and the testing and are the groo membrane will operate down to as low as 40 PSI in my pressure. Okay. Let’s take a look at what this looks like. So what I’m going to do, I could. So here’s my water. Okay. Now in that water you have dissolved solids, right? Including things like salt. What we’re going to do, because of osmotic pressure on this side of the membrane up here, I am going to flow water over that membrane and only the water is going to be allowed to reverse osmosis and go across the membrane. I can do that. I can deadhead that water filtration across the membrane. I can just take a sheet of our membrane and push water through it and make pure water on the other side. The lifespan of the membrane is almost going to be instantaneously gone though, depending upon what the PDS level is, because as soon as if I’m just bearer bearer barry or ring, I’m going to use a different word if I’m just blocking the contaminant from getting through my membranes. Gonna load up like this.
Speaker 1: 04:23
Um, and then you get thing other natures of membrane filtration, like a creep and stuff like that. But the main thing to know is if I, if I just create a wall and pass it and try and pass water through it, the lifespan that membrane, it’s almost going to be instantaneously done. So instead what I do is I flow water over the surface of the membrane and allow my concentrate to escape. I make water across the membrane across one side, and then I allow my concentration to escape to drain. So every ros system is actually making what’s called a concentrate that is going to drain along with the permeate the product water that clean water that it’s putting it into a tank.
Speaker 1: 05:11
What kind of ratio historically that’s been improving over time, uh, when our own membranes were first produced, the ratio of that production, even in best case, was off times in the neighborhood of 15 to 25 gallons of waste water to one gallon of clean water. Now, over time that’s improved overtime. That’s improved a high efficiency Aros 10 years ago, high efficiency Ros 10 years ago would tout the claim of three to five gallons of water down the drain to one gallon of product water. Now that’s a big leap forward. Going from 15 to 25 to three to five is a big leap forward. Now the newest product advancement that we have is what’s called is what’s called pro. Okay, so g r o stands for green Arrow. We didn’t go with Green Arrow. When you say green, there’s a bunch of people that expect that there’s going to be a lot that goes behind that.
Speaker 1: 06:17
If it’s green then it has to do this and it has to be that you can’t just stay green anymore because it means something. So gpro is when it’s tested as a membrane on its own, it makes one gallon of treated water to every one gallon and it puts down the drain. So it’s one to one. Okay, so that’s a membrane. So that membrane is encapsulated with this system. This is our fresh point, our o system, that’s the membrane. It’s clean. It comes in a bag as a replacement, so it’s all clean as far as replacements and stuff. You have to worry about getting contaminated. All comes with double o ring seals and so forth. So this 50 gallon per day, that is a. yes, that’s right Derek, as what the 50 means. Replacing this as easy as what you just did and I’m not very good at it, so it’s probably actually easier if I can do it.
Speaker 1: 07:09
You can gallon tank. This is a diaphragm tank. In the middle it’s welded together. There’s a rubber diaphragm and between the two sides on one side is air, which is pressurized right here. Got a little rugged, a little schneider valve on here that you pressurize up. That’s air on this side. We bring in water on the other side, water pushes on the diaphragm and then pushes that diaphragm down until it equalizes pressure on both sides. These are pre-charged at about six psi of air pressure, so water comes down the side, pushes that diaphragm down. Now the diaphragm is then going to be responsible for when I turn on the Faucet, the diaphragm is what pushes the water out because the membrane is such low production. That’s why I have this storage tank here. That’s why I have about one point, one gallons of of stored water in here.
Speaker 1: 07:55
One point one, one point five, depends on what your next. So this is a three stage arrow. You can see it as three stages as a prefilter that has a membrane and as a post filter hasn’t what’s, what do we need to do to protect the membrane? It’s a poly material. We need to protect it from chlorine, right? We don’t want it to break down because of chlorination. So there’s a carbon filter in there and that’s actually a dfx what’s dfx diamond flow, which is a sediment and carbon in one, so it’s almost like a four state because you have a two stage filter on the front. All right. Three-Stage 50 gallon per day membrane on the three stage, four stage five stage that Jay brought up the four stage five stage, which look just like this, only a little bit wider. The four stage five stage both of 75 gallon per day membranes. And the storage tank isn’t a two point eight, four point two. So this gets a lot more.
