Manganese Sand for Wastewater Treatment

Manganese sand is naturally oxidised and is often better accepted thantraditional sand infiltration systems. The main advantages are:

The oxidation of pollutants. The sand has manganese compounds that are acatalytic oxidiser. Manganese sand filters can chemically remove toxicpollutants, such as hydrogen sulphide, that cannot be removed by physicalfiltration.

Biological Activity Oxidation reactions enhance the biological activity inmanganese sand filters. Secondary biological treatment further breaks downpollutants and improves effluent quality beyond mechanical action alone.

Long-Term Stability Manganese sand has a stable treatment capacity formany years without need for replenishment, unlike chlorination or any otherchemical oxidation techniques. A single investment pays for itself in longer lifethan plain sand.

Low Sludge Production - Combined physical, chemical and biological removalmechanismsThe main benefits are:

Pollutants oxidation The sand contains manganese compounds which serveas a catalytic oxidant. This allows the manganese sand filters to chemicallydestroy toxic pollutants such as hydrogen sulphide which physical filtrationcannot remove.

Flexible Design Manganese sand filters are flexible units that can bedesignedas gravity flow units or radial pressurised vessels optimised fordifferentwastestreams and flow volumes from industrial to municipal

Reliable Operation Manganese sand bioreactors are proven systems with agood track record of handling variable flows and shock loads withoutproblems. Changes of pH and temperature characteristic of manywastewaters do not affect performance.

Cost Effectiveness The material cost of the manganese sand is slightly higherthan the regular sand, but the increased treatability leads to lower longThemain benefits are:

Manganese sand is one of the bestperforming, virtually maintenance-free filter media, and is a natural, powerful reagent.Its multifaceted approach to treatment delivers tremendous value to wastewater utilities and industrial facilities.
