Interview Background:
The Sinopec Baling Yunxi Biochemical Wastewater Project was successfully commissioned in May, featuring Hanqi’s proprietary Ozone Fluidized Bed Technology replacing conventional catalytic oxidation. Post-retrofit results:
➤ Zero catalyst dosing required
➤ >50% COD removal
➤ 50% footprint reduction
➤ No hazardous waste or backwashing
➤ Environmentally friendly operation

Hanqi has now secured another contract with Shanxi Tianji Coal Chemical using this patented technology. Tianji Group – a client since 2015 with 6 collaborative projects over 10 years – consistently chooses Hanqi for its technical excellence, dedication, and service reliability.

Q: Why has Tianji Group chosen Hanqi for 6 projects since 2015?
General Manager Wang:
"First, Hanqi’s corporate culture resonates deeply with us. Their respect for clients, technical precision, and client-centric problem-solving reflect Tianji’s values of responsibility, proactivity, and focus. Second, Hanqi’s expertise delivered measurable results across our projects: fluoride removal, denitrification, decarbonization, and dissolved air flotation technologies all exceeded contractual guarantees."

Factory Director Zhang:
"Hanqi honors commitments. Whether in R&D, design, or execution, they deliver uncompromising reliability. When operational issues arise, Hanqi provides actionable solutions – never evasion. This integrity makes them our first call."

Q: What is Hanqi’s strongest advantage?
Wang:
"Technical superiority that solves real pain points. Examples:

• At our #1300 WWTP fluoride removal project:
  ✓ Footprint reduced to 1/3-1/4 of conventional systems
  ✓ Fluoride lowered from 120mg/L to <15mg/L

• At the water diversion project:
  ✓ Turbidity reduced from 25NTU to 2NTU using loaded sedimentation + homogeneous filters
  All solutions demonstrated long-term stability."

Zhang:
"Undoubtedly technology. Hanqi’s systems operate flawlessly for years – our earliest installation still performs optimally after nearly a decade."

Q: What impresses you most about Hanqi?
Wang:
"Their dual competence: technical mastery paired with service commitment. Their processes are advanced yet simple, stable yet sustainable. Beyond contracted work, Hanqi has freely resolved countless technical challenges for us – a truly valued partner."

Zhang:
"Genuine care beyond commercial transactions. Hanqi never makes empty promises – they validate solutions through testing first. Their meticulousness in every project is exceptional."

Q: Does Hanqi’s Ozone Fluidized Bed offer competitive advantages?
Wang:
"Absolutely. When we needed maximum COD reduction in limited space, Hanqi’s lab tests confirmed their technology’s efficacy. The compact steel-structure design, high efficiency, and eco-friendly operation align perfectly with carbon-neutrality goals. This is the future."

Q: Would you recommend Hanqi? How?
Wang:
"I recently recommended them at an environmental conference. Our fluoride removal system’s decade of stable performance speaks louder than words."

Zhang:
"My endorsement: ‘Technically reliable, team dependable.’ Visit our sites – the results are undeniable."

Q: Suggestions for Hanqi’s future development?
Wang:
"Expand beyond petrochemical wastewater into upstream/downstream sectors. Innovate in zero-liquid discharge while reducing operational costs and energy consumption – this is what clients urgently need amid tightening regulations."

Hanqi’s Commitment:
We will uphold our long-term philosophy and craftsman spirit, transforming client trust into action by:
• Advancing core technologies
• Building comprehensive service systems
• Delivering exceptional value to the industry
