As we all know, industries such as smelters, printed circuit board factories, and electroplating plants often contain significant amounts of heavy metal elements in their wastewater treatment processes, such as copper, iron, zinc, chromium, and silver. Typically, these heavy metals remain in the sludge, causing serious pollution to soil and water resources. However, if we use sludge drying equipment to treat these heavy metals, or metal finishing sludge, the metals inside can be smelted and extracted. This not only protects the environment but also yields considerable economic benefits.

The sludge generated during electroplating wastewater treatment contains harmful heavy metals. It is characterized by easy accumulation, instability, and easy loss. If not properly treated and randomly disposed of, the direct consequence is that heavy metals such as copper, nickel, zinc, and chromium in the sludge may migrate along the pathway of soil, crops, and human bodies under the leaching action of rainwater. This could lead to secondary pollution of surface water, soil, groundwater, and even endanger the food chain, causing serious environmental damage.

Heavy Metal Sludge

In response to the characteristics and hazards of electroplating sludge, and considering environmental pollution prevention and resource recycling, two main treatment methods are adopted: first, after treatment, the sludge is rendered harmless to prevent secondary pollution and disposal; second, comprehensive recovery of heavy metal resources from the sludge is achieved through resource utilization.

TIC Technology Co., Ltd.'s sludge dryer effectively addresses the above issues.

The following is a project showcase of disposal of metal sludge:

●  Project Name: Guangdong Heavy Metal Sludge Drying Equipment Procurement Project

●  Industry Type: Hazardous Waste Treatment (N7724)

●  Project Scale: Daily treatment of 100 tons of heavy metal sludge with moisture content of about 80%

●  Construction Goal: Drying of sludge containing about 80% of moisture content to 40%±2% moisture content. Annual rated operating time of the equipment: ≥ 8,000 hours

●  Heavy metal Sludge Drying System: Including wet sludge receiving system, feeding and weighing system, sludge drying system, steam supply and condensate recovery system, dry sludge transport system, tail gas treatment system, electrical system, and instrument automatic system

●  Heavy metal sludge drying waste types
