ZVI-Based Selenium and Chromium Removal
Unlocking a new era in water treatment, ZeViron™ takes the lead in selenium and chromium removal, revolutionizing the game with its cutting-edge Zero Valent Iron (ZVI) process. This remarkable technology, extending its prowess beyond, also tackles challenging metals oxyanions like molybdenum and antimony. Revolutionary ZVI Process The ZVI process, powered by reactive iron particles, shots, etc., orchestrates the reduction and precipitation of selenium and chromium in a manner unlike any other. Yet, the conventional ZVI processes struggle with slow kinetics, demanding colossal volumes and large tanks, primarily due to the hindrance caused by rust on iron particle surfaces. The challenges intensify when aiming for consistently low selenium concentrations. While various modified ZVI products exist, none has presented an economically viable solution for active water treatment—until ZeViron™. This groundbreaking solution defies ZVI's limitations, offering a unique and cost-effective approach for active continuous water treatment, perfectly tailored for demanding sectors like specifically smelting, refining, power generation, and mining industries where high levels of dissolved solids are present in wastewaters and process solutions. Selenium Removal Mechanism Witness the power of ZeViron™ as it effectively reduces diverse selenium species, including selenate and selenite, to less soluble elemental selenium. 2 Fe + Na2SeO4 + 2 HCl + 2 H2O → 2 Fe(OH)3 + Se0 + 2 NaCl 2 Fe + Na2SeO3 + 3 H2O → 2 Fe(OH)2 + Se0 + 2 NaOH Key Advantages Pure Innovation, No Modifications! The star of the show for this revolutionary water treatment process is also the only process consumable needed, raw and unmodified ZVI with no costly modifications, just pure innovation. And yes, we're even exploring the magic of using scrap iron instead of ZVI. Witness the Extraordinary with ZeViron™ – reducing selenium concentrations from 100 mg/L in wastewaters with up to 70 g/L TDS. Order of Magnitude Faster Kinetics compared to status quo BAT. A Picture-Perfect Result of < 0.002 mg/L at the End of the Pipe achieved in just a handful of hours of retention time from initial concentrations as high as 100 mg/L. The Grand Finale – Residue Stability Tests: TCLP Approved, proclaiming its suitability for landfill disposal or co-disposal with tailings.
