Product Brief
Hazardous waste stabilizer
China ENFI hazardous waste stabilizer is used for the treatment of waste residue containing heavy metals. The stabilizer integrates adsorption, inclusion, chelation, crystallization, mineralization and coordination, and has been successfully applied in the field of non-ferrous metals smelting waste residue treatment and waste residue containing heavy metal stabilization landfill, which can meet the landfill admission requirement of Standard for Pollution Control on the Security Landfill Site for Hazardous Wastes (GB18598-2019).
Specification & Series：ENFI-Z:for general heavy metal waste residue
ENFI-R:for arsenic sulfide slag- Processing Capacity：The agent formulation is designed according to specific conditions, which can meet the standards.
- Application Fields：It is applicable to enterprises that have built or apply for the construction of hazardous waste landfill plants.
The application fields mainly include: fly ash treatment of waste power plants, solid waste treatment (especially hazardous waste containing heavy metals, river sludge, urban sludge, industrial sludge containing heavy metals and slag), and especially suitable for harmless treatment of solid waste with high concentration of heavy metals and complex components.

Advantages & Features
- The pH value of waste residue has a wide range of adaptation;
- It has higher metal-complex stability
- The stabilization process is short and the process is simple
Working Principle
The active components in the stabilizers, through the molecular structure assembly and design, have special chelating properties. With the unique formulation and according to the principle that inorganic compound can react with heavy metals to form compounds with extremely low ionic concentrations, the stabilizer is made integrating adsorption, inclusion, chelation, crystallization, mineralization and coordination.

The Application Achievements
Jinchuan Group Co., Ltd.Hazardous waste category and scale of Hazardous Waste Recycling and Treatment Project in Jinchang City are as follows:
(1) 300t/a neutralized arsenic residue (51.90% water content) produced by White Dust Comprehensive Utilization Project;
(2) 900t/a arsenic-containing waste residue (48.90% moisture content) produced by copper salt plant of Copper Electrowinning Project;
(3) 8500t/a solid waste (45% water content) produced by Acidic Wastewater System Upgrading and Modification Project;
(4) 2400t/a waste residue (46.50% water content) produced by Comprehensive Utilization Project of Shenwu Environmental Technology Co., Ltd;
(5) Other solid waste generated by enterprises in Jinchang region is about 1946.63 t/a (physical quantity) (Zn, Cd and As in the arsenic-containing hazardous waste treated by Jinchuan Hazardous Waste Project exceed the limits and do not meet the entry requirements of hazardous waste landfill, so the waste needs to be stabilized/solidified before it enters the hazardous waste landfill.)
