pictures of a compost brewer please

Discussion in 'Organic Lawn Care' started by Platinum Service, Mar 31, 2008.

  1. I was wondering if some of you could send me pictures of your compost tea brewers. I am looking for pictures that would show how they are made and work. Any help would be appreciated as I intend to build one, I believe that one can be built for much less than the purchase price. You could post them here or look at my contact information to email them.

    Thanks

  3. I'm of the same thinking as you. Where did you get your aerators?

    Here is one from my buddy Bob Posthuma at greater earth organics
    http://greaterearthorganics.com/
    These 275 gallon totes or International Beverage container (IBC's) can be found all over the world, he has made his apperatus to fit inside the tote, it is all stainless steel. He distributes into 10 countries

    It has been tested for years and makes a great product but is not inexpensive, stainless is not cheap. around $3K I believe

    There are some that are affordable and may even save you money that you would spend on running around looking for parts or buying the wrong pump or aerators.

    I did post a sketch for a venturi on this site a little while back if you are planning on using a water pump.

    IMO whether it is worth building your own depends on
    1/ the size; if you are building a large brewer >500 gallons it is probably worth it 2/ if you are going to sell the compost tea you want to know you have a quality product so you may wish to use something proven 3/ if you are able to engineer it properly to circulate and deliver air to all areas of the tank.

    Good luck.

    Salutations,
    Tim

    I have to agree with Tim that if you're going to sell the tea, you'll need to test it to make sure you have a quality product. There are a lot of variables to consider in designing a brewer, but once you have all the system established, it's easy.

    Just make sure that you budget some money for a microscope or lab tests so that you know you are putting out well made compost tea that has all the necessary sets of organisms in reasonable quantity.

    home store pvc and a drill to make an air diffuser

    use as few bends and lots of unions to clean with.

    now you build a spider web shape and suspend it in the center so it spins. the filter bags we use are 400 mesh

    yep thats what we said when we priced a packaged tea brewer 5000 for what?

    I did not total the kit we listed but i am sure that a 300 gallon brewer cannot cost over $2400 to DIY
