Thallium is widely present in metal and non-metal mineral deposits as a by-product element. During the mining and smelting processes, it can lead to the presence of thallium in rainwater, flue gas desulfurization wastewater, and products. In March 2022, the Ministry of Ecology and Environment issued the "Opinions on Further Strengthening the Prevention and Control of Heavy Metal Pollution", highlighting thallium as a newly prioritized heavy metal pollutant for control.
Technical Introduction
CIMC Environmental's thallium removal process involves an "intelligent dosing system + high-efficiency reactor + solid-liquid separation system", characterized by a simplified process and stable thallium concentration in the treated water.
Technical Advantages
High treatment efficiency
The reaction time only takes 10-15 minutes to meet the thallium treatment standards.
High discharge standard
The thallium concentration in the effluent can be reduced to 0.1µg/L.
No secondary pollution
Only a small amount of sodium ions and sulfate ions are introduced, without producing toxic gases such as hydrogen sulfide.
Low sludge production
The sludge production is only 1/5 to 1/10 of that in traditional processes.
