Vifluter Low-Temperature Evaporation & Crystalliza
Arsenic Industry
Vifluter Low-Temperature Evaporation & Crystallization Case
Customer | Honghe Arsenic Industry (Yunnan Tin Group related business) |
Core solution | LTZQ-750 + TA2 - low-temperature evaporation/crystallization for waste reduction and crystallization drying |
I. Company & Project Overview
Customer industry: arsenic (As)-based new materials production and R&D. The wastewater is high-arsenic, high-salinity organic wastewater.
Project objective: reduce wastewater volume, enable crystallization/drying, and facilitate downstream hazardous-waste treatment; the referenced downstream disposal cost is approximately RMB 2,100/t.
II. Wastewater Profile
Wastewater | Mixed production wastewater (alkaline integrated wastewater + acidic wastewater from centrifuge dewatering) |
Flow | Approx. 10 t/day |
Main components | Organics, arsenic, Na+, Cl-, SO4(2-), F-, etc. |
COD | 40-70 g/L |
Arsenic (As) | 20-38 g/L |
Sodium salts | 90-115 g/L |
Chloride | <100 mg/L |
pH | 7-8 |
Operation | Designed for 24-hour continuous operation |
III. Original Treatment & Key Pain Points
Original treatment: single-vessel evaporation + MVR; a ZQ unit was positioned downstream, while the original single-vessel process had been stopped.
Existing situation | Pain point | Business / operational impact |
Own 1.5 t boiler | Relatively high steam dependence | Steam cost approx. RMB 360/t |
Electricity approx. RMB 0.5/kWh | Energy efficiency needs improvement | Low-temperature solution offers potential for energy optimization |
High As, high salinity and COD | Pressure on volume reduction and crystallization/drying | High downstream hazardous-waste disposal cost |
Reuse required | Reuse must be validated by actual distillate quality | Cannot rely on theoretical indicators alone |

IV. Vifluter Solution
Solution direction: for high-arsenic, high-salinity and high-COD wastewater, apply low-temperature evaporation and crystallization for volume reduction and crystallization/drying, with actual distillate quality used as the basis for reuse validation.
Equipment | LTZQ-750, TA2 |
Pilot validation | LTVR-25 pilot test; customer feedback: good performance and low salt in distillate |
Operation | 24-hour operation design |
Key consideration | Altitude effect; vacuum/negative pressure 70-85 (unit not specified in source material) |
Core objective | Wastewater reduction + crystallization/drying + downstream hazardous-waste treatment |
V. Before & After
Available project information confirms that the LTVR-25 pilot test performed well and produced low-salt distillate; project discussions subsequently identified LTZQ-750 and TA2 as the applicable equipment.
Indicator | Original treatment | Vifluter solution |
Process | Single-vessel + MVR; ZQ downstream | Low-temperature evaporation & crystallization |
Pilot | - | LTVR-25; good performance, low-salt distillate |
Flow | Approx. 10 t/day | Designed for 24 h operation |
Equipment | Original single-vessel stopped | LTZQ-750, TA2 |
Reuse | Further treatment/validation needed | Based on actual distillate indicators |
△ Customer-provided wastewater data and project communication notes
VI. Customer Feedback & Economic Impact
Customer feedback: the LTVR-25 pilot test showed "good performance and low salt in the distillate," according to the project communication record.
Economic impact: key project parameters include electricity at approximately RMB 0.5/kWh, steam at approximately RMB 360/t, and downstream hazardous-waste disposal at approximately RMB 2,100/t. The available materials do not provide a complete operating cost per ton, annual savings, or payback period, so these figures are not estimated here.
VII. Sales & Project Progress Highlights
·Clear customer needs: volume reduction, crystallization/drying, downstream hazardous-waste treatment, and distillate reuse.
·Technical validation: LTVR-25 pilot test completed with positive feedback and low-salt distillate.
·Solution alignment: project communication identified LTZQ-750 and TA2.
·Current stage: awarded / won the bid -> agreement under discussion/signing.
