Wholehouse Water Filter For Iron/Magnesium Treatment 1.5 CU FT Birm 1054Whole house water filter for Iron, Magnesium Treatment Birm is an efficient and economical media for the reduction of dissolved iron and manganese compounds from raw water supplies. It may be used in either gravity fed or pressurized water treatment systems. Birm acts as an insoluble catalyst to enhance the reaction between dissolved oxygen (D. O.) and the iron compounds. In ground waters the dissolved iron is usually in the ferrous bicarbonate state
Whole house water filter for Iron, Magnesium TreatmentBirm acts as an insoluble catalyst to enhance the reaction between dissolved oxygen (D.O.) and the iron compounds. In ground waters the dissolved iron is usually in the ferrous bicarbonate state due to the excess of free carbon dioxide and is not filterable. Birm, acting as a catalyst between the oxygen and the soluble iron compounds, enhances the oxidation reaction of iron and produces ferric hydroxide which makes the iron combine into sediment particles and may be easily filtered.
The physical characteristics of Birm provide an excellent filter media which is easily cleaned by backwashing to remove the precipitant. Birm is not consumed in the iron removal operation and therefore offers a tremendous economic advantage over many other iron removal methods.
Other advantages of Birm include:
Negligible labor costs are involved because Birm does not require chemicals for regeneration, only periodic backwashing is required.
When using Birm for iron removal, it is necessary that the water:
If the influent water has a pH of less that 6.8, neutralizing additives such as Clack Corosex®, Calcite or soda ash may be used prior to the Birm filter to raise the pH. A water having a low D.O. level may be pretreated by aeration.
Additions of chemicals to influent or backwash water which contacts Birm media may inhibit iron or manganese removal or may break down or coat Birm media. Chlorination greatly reduces Birm’s activity. High concentrations of chlorine compounds may deplete the catalytic coating.
Polyphosphates are known to coat Birm and reduce Birm’s ability to remove iron or manganese. Before adding any chemical to the influent or backwash water, the chemical's compatibility with Birm should be thoroughly tested.
Clack Birm may also be used for manganese reduction with the same dependability as iron removal. In these applications the water to be treated should have a pH of 8.0-9.0 for best results. If the water also contains iron, the pH should be below 8.5. High pH conditions may cause the formulation of colloidal iron which is very difficult to filter out. All other conditions remain the same for either manganese or iron removal.

Doberman of the Corn: The Movie
Size: One Size, Pattern Name: Corn, Size: One Size, Pattern Name: Corn
My Doberman Godzilla loves this corn. She loves it with every fiber of her being and soul. She is spoiled rotten and has more toys than most children (mostly because if a Doberman does not have things to be entertained by, they will invent their own entertainment that involves the destruction of your home.) She destroyed her first corn plush after about a year. There was some kind of diva like fit and her original corn was in tiny pieces. She was subsequently despondent like a Victorian on a fainting couch so I had to find an emergency corn replacement here on Amazon. I have no idea who the buyer for Amazon is and what made them say: “Oh yes, we MUST sell a big corn plushie for dogs” but I am grateful as hell to the way their possibly deranged mind thinks. Because that person and my Doberman think exactly alike.

Sturdy
Size: 20 x 4 x 4 in, Pattern Name: Pepper
Wanted to wait awhile before writing this review to see how it held up. It is the sturdiest soft toy he has had in while! I love the sound it makes, not loud and annoying like some. Not one tear or seam has come loose and believe me this little Shih Tzu is rough on everything. It is bigger than he is and shakes like nothing else can and stay together. I recommend it for any aggressive pet. I can see a ferret running around with it or a big dog.

Toy provides much fun and hilarity, seam rips.
Size: 20 x 4 x 4 in, Pattern Name: Eggplant, Size: 20 x 4 x 4 in, Pattern Name: Eggplant
So, I kind of bought this on a whim. But our dogs absolutely love this toy, and it provides many moments of hilarity as watching our medium sized dogs tote this giant toy around, whipping it back and forth, hitting themselves with it, is constant entertainment. The squeaker is still working nearly 6 months later, which is amazing. I only took off one star because I have had to perform surgery on this toy multiple times due to the seam coming open, letting the stuffing out, which is a major issue. I have to take it away from them (which they hate) then find time to sew it up until the next spot opens up. If I was smart, I'd just have reinforced the entire seam the first time, but no one said I was smart.
