Rodi waste water uses.Tips?

[Uncle99]

On the assumption you use city water, down the drain, over to city processing, processed, then returned through your tap, for a fee. Then through your RODI and back into your DT. This fee can be a lot in some areas.

The water we use is the same water that’s been recycled by the planet for a billion years.

The problem is not “grey water”, it’s the garbage we dump in our lakes and oceans, or at least, in my opinion.

If we get serious about that issue, we will serve our planet, a billion times better than RODI waste.

They all require a lot of maintenance at the beginning .
As they mature it becomes a lot easier . But … going away for long periods of time is hard.
Auto top off only lasts a few days

Testing … I test salinity , Alkalinity , calcium nitrates and phosphates every Sunday morning .

Never test ph , magnesium , ammonia or nitrite

How old does a tank need to be, tobe considered ‘matured’ in your opinion? Just invested in a Calcium and Alkalinity kit as well as I want to add stoney corals at one point. Thanks for all the info.

I don’t think there is a set timeline.
Saying on day number X your tank is now mature .

Point well made

For me, I see mature as the point in which nitrate and phosphate hold at desired levels, week in week out.

It means all our filtration systems are strong enough to pull out all the stuff that we put in like foods and the fish wastes.

At this point water changes become mute, however, a few water changes a year will keep your trace elements in check, otherwise you can just add these manually.

Thanks for sharing. But bigger tanks are in most cases more stable then small nano tanks right?

Not necessarily ..
if you can stay on top of topping off . As well as exporting nutrients equal to what’s going in .

Yup, volume really helps.
Small volume tanks can be very stable but must be watched carefully as things happen much faster that larger volumes.

Wait… for what you use AND flush? Would ultrafiltration also remove the salinity you think? Where would you take a water sample like that to get it tested? TY

Ultrafiltration removes insoluble particulates down to 0.025 ppm. Just a finer sediment filtration process. Does not remove salts or items such as calcium or magnesium.

Not sure how much of a concern salt is for items such as plants. RODI doesn't add salts, just concentrates what was in the original source into that waste. If one is watering plants with municipal water than I struggle to see how that concentrate suddenly became an issue.

Thanks for explaining. I’m not sure either how much salt is bad for plants. I mostly water them with the waste water from my fresh water tanks.

How I think of it. RO gonna waste minimum two to four gallons for one which means that waste has twice to four times the concentration of contaminates and unless the only water being used to water the plants then likely not going to be material enough when combined with all the other water ultimately being sprayed on those plants. Plus not all bad. Plants need many of the minerals being thrown out with that waste.

At a minimum. Ultrafiltration removes pesticides which should help all involved. Worth exploring the possibility.

I’ve been looking into it and I’ll probably explore that. Thanks for sharing your point of view.

My RO waste water drains out to my backyard where the grass is noticeably thicker/greener, and grows a lot faster than the other areas, so I'd use it for plants.

4L @ 100ppm in
1L out @ 0.0ppm
3L out @ 400ppm

That must be the new math they are teaching.

In most cases the waste line water is quite a bit cleaner than tap water.

3L/@133.333ppm would conserve mass particles in the equation.

Before accounting for sediment, carbon and possibly a DI filter correct. I mean new math. 2M parts per M

I cannot take credit for this. My wife is a USGS hydrologist/geologist. It is her take. I only go along because it's also the easiest path.

We call that a hydrogeologist...

 

[Townes_Van_Camp]

Her title is Geologist. But she'sore proud of the hydrology masters vs the geo masters.

What I do is avoid talking ing to her about those things. She goes way over my head.

PG is a pretty nice moniker. My wife is a certified Ecologist Emeritus. I am just the GIS guy...

To be on topic, we have an on demand hot and cold RODI system for cooking and drinking. The waste just runs out to the septic system.

Could be a missed opportunity?
