Promising Future of Sludge Rotary Dryer

Sep 16 2015

 Sludge is the product of the sewage processing, with high moisture content, easy to corrupt and smelly, smaller pellet, a gum liquid and difficult to handle. The emergence of sludge rotary dryer makes sludge "turning waste into treasure", play a great role in industrial production . The following is brief analysis from sludge hazard and the role of the sludge rotary dryer.

1. Sludge hazard

There are three main sludge hazards: water pollution, soil pollution, air pollution. The first is the sludge water hazards, excessive heavy metals contained in the sludge, the dumping sludge in the ocean will cause a large area of fish and shrimp died; then is the harm to the soil, because sludge contains toxic chemicals and pathogenic microorganisms, its simple landfill or open dumps, which will produce a chemical reaction, destroy the soil structure, which harmful substances may penetrate the soil and then be absorbed by plants; the final is air pollution, sludge will release harmful gas after the organic matter is decomposed by microorganisms.

2. The role of sludge rotary dryer

Dried sludge has a significant role, which must rely on collaboration of sludge rotary dryer. Fote sludge rotary dryer coal-saving nearly up to 20 percent, creating more value for our customers. Adopting multi-stage purification dust removal equipment, greatly reduces equipment pollution for environment, it can be sent to the cement plant and used for cement production; it also can be used for soil conditioner, tailings piles, quarries, open-air coal pit reclamation. Such sludge drying not only solve the environmental problems, but also provides users with a considerable economic value, as well as conducive to the sustainable development of society.
