Sludge/Wastes containing Heavy Metals by Stabilization Technology using Polymeric Resins
The innovator has developed stabilization technology for different heavy metal wastes containing chromium, lead, mercury, nickel, manganese, zinc, cadmium and arsenic. The technology employs polymeric resins as immobilization meterials,which helped to overcome the deficiencies in existing technologies such as:
-
Low leachability good bonding with contaminant
-
Minimum effect of temperature and water absorption
-
Outstanding chemical & corrosion resistance (acids, alkalies, salts) atmospheric degradation
-
High mechanical strength (tensile, compressive & flexural) & impact resistance (15-22 kg.cm/cm)
-
Thermal stability
-
Excellent adhesive properties with metals (active hydrogen)
-
Dried metal bearing sludges can be directly incorporated into matrix without any wetting medium
-
Volumes of hazardous materials handled are minimized
-
Economical equipment sizing
-
Simple processing procedure and curing at room temperature
