The Best DMI-65 Filter Media Price in Bangladesh

DMI-65 stands as a pioneering solution in water treatment, offering an innovative approach to iron and manganese removal. Originating from Australia, this silica sand-based activated granular filtration media has set new standards in the water purification industry. DMI-65 features a distinctive micro-porous structure and enduringly fused active components, differentiating it from conventional iron removal media. DMI-65 is world innovative silica sand based activated granular filtration media from Australia. It is active components are enduringly fused into the grain that is totally different from other iron removal media. DMI-65 is exclusively designed for the removal of iron and manganese from water. It is also removing arsenic, aluminum, hydrogen sulfide and other heavy metals from water. The interesting matter that, it does not require the use of Potassium Permanganate. The special technology and it’s unique micro-porous structure of DMI-65 efficiently removes dissolved iron to as low as 0.3 ppm and manganese to 0.5 ppm. This Australian special coated Iron Removal Media acts as an oxidation catalyst with immediate oxidation and filtration of the insoluble precipitates. The media has been used extensively in a wide variety of applications for over 30 years. DMI-65 has been tested and certified by the Water Quality Association in accordance with NSF/ANSI 61.

Description:

Designed exclusively for iron and manganese removal, DMI-65 surpasses traditional media by efficiently eliminating arsenic, aluminum, hydrogen sulfide, and other heavy metals from water. Notably, what sets DMI-65 apart is its ability to achieve these results without the need for Potassium Permanganate. The media acts as an oxidation catalyst, facilitating immediate oxidation and filtration of insoluble precipitates, showcasing its effectiveness in diverse water treatment applications.

Advantages Of DMI-65

● It Eliminates Potassium Permanganate and require of sodium hypochlorite to low (0.2 ppm) residual.

● It is suitable and satisfactory performance at pH 5.8 to 8.6.

● DMI-65 operates satisfactorily at linear filtration velocities of up to twice that of conventional media, reducing capital costs considerably.

● This media can operate maximum temperature of 45°. C.

● It is not consumed in the process, providing considerable advantage over other medias.

● Reactivation Not Required. Only requires initial sodium hypochlorite activation.

● System Compatibility. Physical properties are similar to that of other comparable systems, allowing switch without major hardware modifications.

● DMI-65 has been shown to remove significant amount of arsenic associated with iron-containing influent. The precipitation chemical Iron III Chloride is used for high arsenic feed levels.
