🛠️ Tools and Preparation for Media Loading

This paragraph lists the tools and media required for successful media loading. The necessary items include an empty bucket for transferring media, a funnel, scissors, masking tape, plastic pipe caps, and media types such as carbon, calcite, and gravel underbedding. The demonstration uses a 12-inch carbon filter, with an estimate of one-sixth cubic foot of gravel required to cover the riser screen. It is explained that smaller tanks use fine gravel, and Pure Aqua has already done the calculations for media and gravel quantities based on the tank's size and flow rate.

⚠️ Safety and Pre-Loading Checks

Safety is emphasized, with a recommendation to follow local safety codes and use protective equipment like gloves and masks to prevent inhalation of fumes during media loading. Before beginning the loading process, it is important to check that the riser pipe is cut to the correct length and the diameter matches the valve. This ensures a safe and correct installation of the media.

🔩 Step 1: Centering the Riser Pipe

The first step in the media installation process involves ensuring that the riser pipe is centered inside the tank. A plastic cap is placed on the pipe to prevent media from entering. It’s recommended to use a flashlight to verify the alignment since adjusting the pipe after media loading would be difficult. A funnel is then placed on top of the tank to ensure all media is correctly directed inside.

💨 Step 2: Loading the Fine Gravel

The second step involves loading the fine gravel into the media tank. For smaller tanks, a portion of gravel should be transferred to a bucket before being funneled into the tank. The paragraph explains the importance of pouring the gravel carefully to avoid clogging, as the tank’s opening is small. The amount of gravel should be verified by using a flashlight to ensure it covers the screen at the bottom of the tank. Once enough gravel has been loaded, and it is visually confirmed, the process can move forward.

🧱 Step 3: Loading the Activated Carbon Media

After verifying the gravel is in place, the next step is to load the activated carbon media. It’s important to ensure the right speed when pouring to avoid overfilling and to carefully measure the media volume. Pure Aqua pre-calculates media amounts for different tank sizes, but freeboard (the space above the media) must still be checked after loading. The funnel is then removed, and the riser pipe cap is taken off. Any dust or fines around the threads should be cleaned before proceeding to valve installation.

🔧 Final Steps and Maintenance Tips

This paragraph outlines the final steps after media loading, including how to clean the tank's top and measure the freeboard for documentation and maintenance purposes. Freeboard height is essential to monitor media loss. The frequency of carbon media replacement varies, typically between 6 to 12 months depending on operating conditions. Monitoring the concentration of compounds before and after filtration helps determine when media replacement is necessary. For purchasing high-quality NSF-certified carbon media or tanks, Pure Aqua's sales team can be contacted. The video concludes with a thank you to the viewers.

💡Activated Carbon

Activated carbon is a type of filtration media used to remove organic and inorganic compounds, such as chlorine, taste, and odor, from water. In the video, it is described as being commonly used in smaller commercial reverse osmosis (RO) systems as pretreatment. The demonstration involves loading two bags of activated carbon into a 12-inch FRP tank.

💡FRP Tank

FRP stands for 'Fiberglass Reinforced Plastic,' a material commonly used to make water filtration tanks due to its durability and corrosion resistance. In the video, the 12-inch FRP tank is the vessel into which the activated carbon media is loaded, with specific instructions provided for correctly filling the tank.

💡Gravel Underbedding

Gravel underbedding is a layer of fine gravel placed at the bottom of the filtration tank to support the filtration media. It helps to distribute water flow evenly and protect the riser pipe from clogging. The video mentions that the gravel layer should be enough to cover the riser pipe screen, ensuring efficient filtration.

💡Riser Pipe

The riser pipe is a key component inside the FRP tank that helps guide water to and from the filtration media. It must be properly centered in the tank, and the video emphasizes the importance of checking this alignment before media loading. The riser pipe is also temporarily capped to prevent media from entering it during the loading process.

💡Filtration Media

Filtration media are materials that help remove contaminants from water. Activated carbon is one example, and the video shows how to properly load this type of media into an FRP tank. Different tanks require different types and quantities of media, which are calculated based on design criteria and flow rates.

💡Freeboard

Freeboard refers to the space between the top of the filtration media and the top of the tank. It allows room for the media to expand when water flows through it. The video explains the importance of documenting the freeboard after loading the media, as it helps monitor potential media loss during operation.

💡Safety Equipment

Safety equipment, such as gloves and masks, is necessary to protect personnel during the media loading process. The video stresses the need to follow local safety codes to prevent inhalation of dust or exposure to harmful fumes, especially when handling filtration media like activated carbon.

welcome to pure aquas Learning Center in

this series of videos we will

demonstrate the loading of filtration

media inside different size FRP tanks in

this particular video will demonstrate

the loading of carbon media inside of a

12-inch FRP tank activated carbon media

is typically used for the removal of

organic and inorganic compounds it's

effective at removing things like

chlorine taste and odor smaller size

commercial rro systems typically have

carbon media as pretreatment as it's a

very cost effective way of removing

these kind of compounds

[Music]

some of the items shown here are the

tools and media are recommended for

successful media loading so starting

from this side here we have an empty

bucket where you know the media in the

backs can be transferred to this bucket

and then dumped into the tanks we have a

funnel scissors masking tape plastic

pipe caps and of course different types

of media you know in this case we're

showing carbonate calcite and of course

the gravel under bedding since this

particular video will cover the loading

of a 12 inch carbon filter sure aqua

recommends loading just enough gravel to

cover the riser screen at the bottom of

the tank so we estimate roughly about

one-sixth a cubic foot will be needed to

cover the riser pipe here on the bottom

or riser screen and we use on smaller

tanks would use fine gravel which is

about 8 inch by quarter inch in diameter

and two bags of carbon media

so this particular demonstration

involves a 12-inch media tank now there

are many different sizes of tanks with

many different types of media of course

so it's up to you know design

calculations and criteria to determine

exactly the quantity of media needed and

gravel under bidding quantity as well of

course you're a pure aqua we've done our

specific and precise calculations for

our specific media sizes and tanks to

make sure our design and flow rates are

adequate for each tank size most

importantly is of course the safety of

the personnel involved in loading these

type of media filters now we would leave

that up to the local local code that

predetermined that what kind of safety

equipment or protection is needed for

the personnel such as gloves or masks

they'll prevent of course inhaling any

kind of fumes and so on when loading

these media filters before beginning the

media loading it's important to

double-check and ensure that your riser

pipe is cut to the right length and the

diameter matches that on the valve used

with that we will begin the media

installation

[Music]

so step one of the media installation

would be to ensure that your riser pipe

is centered up in the inside of the tank

and of course the center of the pipe is

covered with some kind of easy to remove

plastic cap it doesn't hurt you take

some kind of flashlight and just

double-check that the the actual riser

pipe is centered up because once the

media is loaded of course it'll be very

difficult to realign the riser pipe

so of course before pouring any gravel

or media into the tank you'd want to

place the funnel on the top of the thing

so you ensure all the media easily goes

into the tank step two would be loading

the fine gravel into the media tank

before doing that of course you would

recommend transferring a small amount of

gravel into the bucket that we showed

earlier in the video as these tanks are

slightly smaller of course on larger

tanks all the gravel can be poured

directly into the dam but again since

we're using less than a bag you'd want

to transfer a little bit into a bucket

and then transfer that into the tank

[Music]

said of course as you're pouring the

gravel into the tank you're gonna want

to maybe move it around so it goes in a

little bit easier as it tends to get

stuck because the tank opens a little

bit small with a larger riser pipe after

loading your first amount of fine gravel

into this tank you'd want to double

check and take the take a flashlight and

make sure that the gravel level is

slightly above the screen on the bottom

if it's not of course you're going to

load more gravel you know as mentioned

before we have a predetermined gravel

amounts already calculated but if your

gravel or nuts are not calculated you

know these steps aren't necessary so

once you've determined that enough

gravel has been loaded and of course

that's been double-checked visually it's

now safe to proceed to our third step

which would be the loading of the

filtration medium now as mentioned

before we have predetermined media

volumes or quantities that will they get

pre-loaded in each diameter tank with

that even being said it is still

important to measure and ensure that you

have enough freeboard and document that

at the very end which we'll show how to

do so with that we will load two bags of

activated carbon media and in this video

as you're loading the carbon media into

the tank and you want to pour at the

right speed so you're not over spilling

and just ensuring that the carbon goes

into the tank as fast as it's coming out

of the back once the correct amount of

media has been loaded into the tank of

course your drew move your funnel take

off your your cap here on the riser pipe

and clean up any really dust and small

media fines around the thread before

loading your valve now once your media

has been loaded inside the tank its of

course and your top cleaned you can

follow other periodical videos on how to

install your control valves onto the top

of the tank and program and so on but

before doing that of course you'd want

to measure how much freeboard is

actually in this tank probably document

that for maintenance purposes as this

freeboard volume or height is important

as it determines if there's a media loss

and so on now you know some operators

might ask how often do we replace our

carbon media of course as mentioned

earlier in our video carbon media

removes many different types of

parameters be it inorganic organic

compounds now for the particular

compound you're trying to remove it's

important to measure your concentration

before and after the filter and monitor

that over

maybe a course of six to twelve months

typically we see carbon media lasting

between 6 to 12 months and of course

based on your exact operating conditions

you can determine exactly how often this

meet needs to be replaced now for the

purchase of any high quality NSF

certified activated carbon media of

course our sales team can be contacted

at any time be it if to buy carbon media

replacement or brand new tanks for new

projects with that that concludes our

pure off the toilet video and we thank

you for watching
