Well pack gravel is used for deep beds in ground wells to form barrier between the screens and the land’s natural deposit, which in turn allows for very clean water from the well. Other applications may include well de-watering and pool monitoring

Specification

is formulated from a gluconate greensand, which is capable of reducing iron, manganese and hydrogen sulfide from water through oxidation and filtration. When the oxidizing capacity power of the manganese greensand bed is exhausted, the bed has to be regenerated with a weak potassium permanganate (KMnO4) solution thus restoring the oxidizing capacity of the bed. 1.5 to 2 ounces of potassium permanganate, in solution, per cubic foot of manganese greensand is considered sufficient for normal regeneration. It is required to vigorously backwash and regenerate the bed when it is placed in service and before its oxidation capacity is totally exhausted.

Specification

Birm is an efficient and economical method of removing 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 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 Fe + + to Fe + + + and produces ferric hydroxide which precipitates 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

The advantages of Birm include: long material life with relatively low attrition loss, a wide temperature performance range and extremely high removal efficiency. Negligible labor costs are involved because Birm does not require chemicals for regeneration, only periodic backwashing is required.

Specifications

It is a high capacity filter medium for the removal of hydrogen sulfide, iron or iron, and manganese. Chemical regeneration is not required, since these contaminants are oxidized on the surface of the average, and then removed by a simple backwash. The characteristics of the design flow are similar to those of green sand. Higher capacities and the non-requirement of regenerants make PYROLOX an economical alternative to iron removal.

A naturally extracted mineral, Pyrolox contains in its entirety manganese dioxide that has been used in water treatment for more than 75 years. Pyrolox is a granular filtration medium to remove hydrogen sulfide, iron and manganese reduction. Pyrolox works like a catalyst, but in itself it remains relatively unchanged. Pyrolox works initially by which hydrogen sulfide, iron and manganese oxidize and get caught in the filter media, while the simple backwash cleans the bed.

Specifications

is a kind of filter used in water treatment. The product has large surface area, and its various indexes all exceed the construction department’s standard. Anthracite filter media is especially selected from the
deep well minerals, so it can contain the highest percentage of carbon. The raw material is always filtered and washed to make sure that the product can have a good effect on water filtration.

Coconut shell granular activated is used specifically in air and vapor filters for eliminating odors and toxic vapors. Granular activated charcoal can also be placed in free low containers to adsorb offensive or unpleasant odors in confined areas; one of the most common applications for activated carbon is the reduction of the undesirable tastes and odors present in many chlorinated water supplies. Activated carbon has been successful for many years in the reduction of free chlorine from water supplies. The product is clean, fresh water with no objectionable taste or odor characteristics.

is highly fractured edges and irregular surfaces provide a high surface area and complex flow path for efficient removal of suspended matter throughout the filter bed, typically reducing suspended solids down to the 20-40 micron range. Filter-Ag’s larger particle size creates less pressure loss, allows deeper particle penetration into the bed for greater sediment loading, and extended filter run cycles. Filter-Ag relatively lightweight allows for lower backwash flow rates and better bed expansion to release trapped sediment during backwash. Filter-Ag can be used in both pressure and gravity flow systems. It can also be used as a layer in multi-media filter designs allowing a more flexible approach to difficult filtration problems.

Specifications

• Upon installation allow bed to soak overnight before backwashing
• Reduced shipping cost due to light Weight/cu. ft.
• Replacement of sand with Filter Ag in existing installations may increase filter capacity 100% or more. (Caution should be taken upon start-up that the lightweight Filter-Ag is not washed to drain.)

has outstanding physical strength for a standard gel-type resin that allows lengthy lives without the growth of unnecessary stress fall; it also demonstrates excellent exchange kinetics, allowing very small concentration concentrations of both powerful and soft acid anions to be obtained at practical flow rates.

is a high-capacity premium grade bead from natural polystyrene sulphonate cation exchange resin designed solely for the therapy of foodstuffs, drinks, portable waters and water used in food preparation. Its high bead integrity, excellent chemical and physical stability and very low extractable content make a significant contribution to its successful use in this area.
