Birm Media is a black granular filter material used for removal of iron and/or manganese from water in pressure or gravity systems. It contains an active insoluble catalyst to precipitate iron and/or manganese. Because the presence of iron is most common, iron removal is the usual application for Birm. Under suitable conditions, the iron and dissolved oxygen in water react on contact with the Birm filter bed and, as a result, the iron is precipitated in the form of hydroxide. This is a flocculent material which is filtered out in the bed of Birm. Periodic backwashing flushes out the accumulated iron and the Birm is again ready to perform its function. Birm is not consumed in the iron removal operation. For Birm to effectively remove iron, the pH of the raw water must be greater than 6.8. If both Iron and Manganese are present, the pH should be between 7.5 and 8.5. For Manganese removal the pH should be between 8.0 and 9.0 for best results.

Advantages:

• No chemicals to purchase for maintenance. Regeneration not required.
• Iron removal efficiency is extremely high.
• Negligible labour cost. Only periodic backwashing required.
• Durable material with a long life.
• Wide temperature range application.
• Certified to NSF/ANSI Standard 61.

MnO2 - Manganese Dioxide is used to remove iron and manganese from drinking water by a process of catalytic oxidation.

Physical Characteristics:
Chemical Properties:

• Natural manganese ores specially selected for their high catalytic activity, free from contamination and with no additives, are used in the production of this manganese dioxide. The manganese content varies between 55 and 85% as MnO2, but the catalytic activity is not dependent upon the manganese content.

Uses:

• Removal of Arsenic, Iron, Manganese, and heavy metals from potable water and water intended for bottling, brewing or soft drink manufacturing.

Manganese Green Sand is capable of reducing iron, manganese and hydrogen sulfide from water through oxidation and filtration.
About Manganese Greensand Iron Reduction Media Filters
Manganese Greensand is formulated from a glauconite 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.

Advantages of Manganese Greensand Filters:

• Iron reduction over wide pH range
• Effective reduction of hydrogen sulfide in addition to iron and/or manganese
• No harmful effects from a chlorine feed
• Low attrition for long bed life
• Manganese Greensand Operating Limits:
• Maximum Water Temperature: 80°F (26.7°C)
• pH Range: 6.2 to 8.5

Green Sand is formulated from a glauconitic green sand which is capable of reducing iron, manganese and hydrogen sulfide from water through oxidation and filtration. Soluble iron and manganese are oxidized and precipitated by contact with higher oxides of manganese on the green sand granules. The hydrogen sulfide is reduced by oxidation to an insoluble sulfur precipitate. Precipitates are then filtered and removed by back washing. When the oxidizing capacity power of the Green Sand 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 to 2 ounces of potassium permanganate, in solution, per cubic foot of Green sand 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. Operating the bed after oxidation capacity is exhausted will reduce its service life and may cause staining.

Specifications:

• Green sand: Color: Purple-black
• Density: 39 kg per cubic foot
• Specific Gravity: Approx. 2.4
• Screen Grading: Approx. 18 x 60 mesh
• Size: 0.30 to 0.35 milli meters
• pH Range: 6.2 8.5

Thiourea, also called thiocarbamide, an organic compound that resembles urea but contains sulfur instead of oxygen; i.e., the molecular formula is CS(NH2)2, while that of urea is CO(NH2)2. Like urea, it can be prepared by causing a compound with the same chemical composition to undergo rearrangement, as by heating ammonium thiocyanate (NH4SCN). A method of preparation more commonly used consists of the addition of hydrogen sulfide to cyanamide. Thiourea exhibits many of the chemical properties of urea, but it has little commercial application. The small quantity of thiourea consumed is utilized primarily in photography as a fixing agent, in the manufacture of a thermosetting resin, as an insecticide, as a textile-treating agent, and as starting material for certain dyes and drugs. Thiourea forms as colourless crystals melting at 182° C (360° F).
