1. Introduction:

– Made in Vietnam.

– Usage: remove impurities suspended in water.

2. Technical features:

– Particle size: 1.5 – 3.5mm; 0.7 – 1.2mm

– Weight: 700 – 800 kg / m3 (depending on size)

– Porosity: greater than 45%

3. Advantages:

Due to its large sediment storage capacity, it is suitable for treating water with high turbidity. Increase filtration cycle.

– Can be used together with sand in existing filter tanks without changing the tank / tank structure.

4. Scope of application:

– Can be used in graviry filter tanks or pressure filters tank. Filter direction from top to bottom.

5. Recommended use:

– Combine with filter sand to remove impurities suspended in water.

– The minimum thickness of the coal layer is 0.40 – 0.45 m.

– Immediately after changing the filter material layer, it is necessary to wash back to remove the coal dust.

– Wash and filter: backwash when the filter cycle ends. Washing water intensity is 10 – 12 l / s.m2. Washing time 10 – 15 minutes.

– Need to wash before using.

– Made in Vietnam from coconut shell charcoal by the method of activation at a temperature of 900 – 1.0000C.

Uses: deodorizing, odor, heavy metals, organic compounds, pesticides.

2. Technical features:

– Particle size: 1.68 – 3.36 mm (mesh size 6 – 12); 2.36 – 4.76 mm (mesh size 4 – 8)

– Density: 520 – 550 kg / m3

– Black, dry, loose, angular seeds.

– The basic targets:

Basic indicators:

– Iodine index: 650 – 850mg / g

– Adsorption CCl4: 40 – 60%

– Benzene: 23 – 33%

– Methylene Blue: 130 – 170ml / g

– Hardness index:> = 95%

– Ash degree: 2-5%

– Humidity: = <6%

– pH: 7-8

3. Advantages:

– This product is cheap compared to imported goods, has high quality standards, can be used in water treatment projects and wastewater.

– Usage time depends on the amount of poison to be treated.

4. Scope of application:

– Deodorization, odor, heavy metals, pesticides, organic compounds.

5. Recommended use:

– Filtering speed depends on the type of poison on water. For example, reducing residual chlorine content – 40 m / hour; reduction of organic compounds – 6 m / hour.

– The thickness of the coal layer is 0.7 – 0.9 m.

– Sometimes it is necessary to carry out backwashing to disturb and redistribute the coal layer.

– Need to wash before using.

Birm is an iron-reducing material widely used in water filtration systems with the ability to remove iron content, remove precipitates and easily clean impurities in water. In particular, the Birm is known for its stable structure in the reaction of iron that is difficult to dissolve, very safe and has a long lifespan.

Scientists have been looking for a lot of natural materials that can remove iron and alum from water such as manganese sand … and Birm is one of those types.

The iron reduction Birm is one of the most economical and effective filtration solutions available today.

Iron is one of the heavy metals that normally exists in water, which will have extremely serious consequences when we use them for a long time. The human body cannot absorb and remove heavy metals by itself, leading to a number of diseases such as kidney stones, cancer …. is inevitable.

Main uses of Birm

Birm seeds act as a catalyst between dissolved iron and oxygen compounds that enhance Fe ++ oxidation reactions to Fe +++ and produce precipitated iron hydroxide to completely remove iron from groundwater.

Birm water treatment seeds are also used to reduce manganese in water. Water with a pH between 8.0 – 9.0 gives the best results when reducing manganese with Birm seeds. Water after being removed both manganese and iron will have a Ph below 8.5.
