Storring RO/DI Water

[WEISER]

Whats the best way to store RO/DI water and for how long?

[ScottT1980]

The best way is whatever works for you IMO. I used a Brute, 55 gallon rubbermaid trashcan. However, this worked because my RO/DI unit was in the garage. Currently in my new house, I only store RO/DI water 5 gallons at a time with the standard water storage containers.

We use 1 gal water jugs that I have emptied out from work. (Distilled water for sterilizing surgical instruments) We have about 5 of them. We fill them up and use as needed. Usually takes about a week maybe under to go through them.

33 gal rubbermaid food safe trash can, in the computer room closet along with the r/o di unit. it's right next to the bathroom. small hole in the wall and wahla plumbing in the closet.

I agree with scottT1980. last project I had 2 - 50 gal barrels (like rubber maid), level indicatiors built in side wall with 5/8 tubing, pumps for circulation and air, one for salt mixing (water changes) and one for makeup. I have also used the gallon milk jugs, throughly cleaned of course. have used as many as 25 filled from 50 gal barrel and used as needed. barrel refilled when mostly empty. you can use what ever works for you. duration of storage should not be an issue if the container is clean and no contaminates can enter. good luck.

i have a 33 gallon rubbermaid trash can in the garge elevated on a stand i have a hole at bottom witha valve to drain water out and i pipe in ro/di water through the lid of the can this keeps out airborne dust and insects the lid stays on no water evaporates and alwyas have 33 gallons of water made. i make up a full can every 2 weeks or so

[forestal]

I have a 96 gallon garbage can for storage, and 55 can for saltwater...premixed and have plenty for my weekly water changes...then i have 50 gallon can with ro/di for topoff of my big system....
i want to get some valves and set up so it fills automatically but no biggee...but yes i have lids on at all times

[KimPossible]

I keep mine in 5gal water jugs...easier to fill and refill.
I keep um covered up with a blanket since they are clear.
I dont have an RO in my house.....gotta go out and get it.

Oi!

I have mine in 32 gal rubbermaid 'storage containers'. You can have a powerhead in them and it will circulate the water 'better' than in a 55 gal garbage can. Let me explain that, the air won't come out when it is too deep, and I don't have big water pumps, so if the powerhead is just 6 inches below the water surface the air will still come out, that is not to say that 55 gal cans won't work, it's just that they don't work for me. Anyway the surface to volume ratio is better in a 'flat' container then a deep one, it's just what I use.

Cheers!

I know this is very late, but it is well worth noting.

You must use RO or DI compatible materials. I have seen TDS come out ZERO of a RO/DI unit, and over 300 ppm coming off of a recycled plastic container.

Needless to say the tank crashed. The owner didn't check the TDS in the storage vessel....

You really need to ask the maker of the container you want to use. ANY manufacture of a container that can not answer you, DO NOT use.

Rubber maid is very good for this, they know their stuff, but...some of their containers are NOT good, but they will tell you which are suitable.

Excellent info AquaFX. Thanks!


Ohhhh... Welcome to Reef Sanctuary!!

[Gina]

I have to say, I didn't realize that! We will be sure to check our readings from the container before we start mixing the salt.

Thanks for the alert! And welcome!!

On the bottom of a plastic container there is a triangle with a number inside of it, for long-term water storage your better off using a 1 or a 2, I have a Rubbermaid trash can that has the No. 4 which I use for mixing up my salt water and then using it within the day or two. but the long-term storage your better off using a # 2

Wow.. great info Mark! Thanks!

#1 PETE


Descriptions
Polyethylene Terephthalate (PET, PETE). PET is clear, tough, and has good gas and moisture barrier properties. Commonly used in soft drink bottles and many injection molded consumer product containers. Other applications include strapping and both food and non-food containers. Cleaned, recycled PET flakes and pellets are in great demand for spinning fiber for carpet yarns, producing fiberfill and geo-textiles. Nickname: Polyester.

Properties
Clarity, strength, toughness, barrier to gas and moisture, resistance to heat

Packaging applications
Plastic soft drink, water, sports drink, beer, mouthwash, catsup and salad dressing bottles. Peanut butter, pickle, jelly and jam jars. Ovenable film and ovenable prepared food trays.

#2 HDPE


Descriptions
High Density Polyethylene (HDPE). HDPE is used to make bottles for milk, juice, water and laundry products. Unpigmented bottles are translucent, have good barrier properties and stiffness, and are well suited to packaging products with a short shelf life such as milk. Because HDPE has good chemical resistance, it is used for packaging many household and industrial chemicals such as detergents and bleach. Pigmented HDPE bottles have better stress crack resistance than unpigmented HDPE bottles.

Properties
Stiffness, strength, toughness, resistance to chemicals and moisture, permeability to gas, ease of processing, and ease of forming.

Packaging applications
Milk, water, juice, cosmetic, shampoo, dish and laundry detergent bottles; yogurt and margarine tubs; cereal box liners; grocery, trash and retail bags.

#3 V


Descriptions
Vinyl (Polyvinyl Chloride or PVC): In addition to its stable physical properties, PVC has excellent chemical resistance, good weatherability, flow characteristics and stable electrical properties. The diverse slate of vinyl products can be broadly divided into rigid and flexible materials. Bottles and packaging sheet are major rigid markets, but it is also widely used in the construction market for such applications as pipes and fittings, siding, carpet backing and windows. Flexible vinyl is used in wire and cable insulation, film and sheet, floor coverings synthetic leather products, coatings, blood bags, medical tubing and many other applications.

Properties
Versatility, clarity, ease of blending, strength, toughness, resistance to grease, oil and chemicals.

Packaging applications
Clear food and non-food packaging, medical tubing, wire and cable insulation, film and sheet, construction products such as pipes, fittings, siding, floor tiles, carpet backing and window frames.

#4 LDPE


Descriptions
Low Density Polyethylene (LDPE).Used predominately in film applications due to its toughness, flexibility and relative transparency, making it popular for use in applications where heat sealing is necessary. LDPE is also used to manufacture some flexible lids and bottles and it is used in wire and cable applications.

Properties
Ease of processing, strength, toughness, flexibility, ease of sealing, barrier to moisture.

Packaging applications
Dry cleaning, bread and frozen food bags, squeezable bottles, e.g. honey, mustard.

#5 PP



Descriptions
Polypropylene (PP). Polypropylene has good chemical resistance, is strong, and has a high melting point making it good for hot-fill liquids. PP is found in flexible and rigid packaging to fibers and large molded parts for automotive and consumer products

Properties
Strength, toughness, resistance to heat, chemicals, grease and oil, versatile, barrier to moisture.

Packaging applications
Catsup bottles, yogurt containers and margarine tubs, medicine bottles

#6 PS


Descriptions
Polystyrene (PS). Polystyrene is a versatile plastic that can be rigid or foamed. General purpose polystyrene is clear, hard and brittle. It has a relatively low melting point. Typical applications include protective packaging, containers, lids, cups, bottles and trays.

Properties
Versatility, insulation, clarity, easily formed

Packaging applications
Compact disc jackets, food service applications, grocery store meat trays, egg cartons, aspirin bottles, cups, plates, cutlery.

#7 OTHER



Descriptions
Other. Use of this code indicates that the package in question is made with a resin other than the six listed above, or is made of more than one resin listed above, and used in a multi-layer combination.

Properties
Dependent on resin or combination of resins


Packaging applications
Three and five gallon reusable water bottles, some citrus juice and catsup bottles.

and to thionk i thought those numbers were for me to know which recycling bin to toss them in too,,,LOL

good info~
