Customers' Appraisal from Daqing-China Oil City
  
     
 
Report 1


We bought Bidun HY50BR-Ⅲ High-Efficiency Oil/Water Separation and Respective Recovery System with the treatment capability is 50 ton/hr half a year ago. The operation and test data prove that:

I. The system is advanced, stable and precise. The oil content of treated water is controlled under 0.3mg/l, which conforms to the national standard on oil content of inlet water for steam boilers. It is a great improvement comparing to the situation in the past.

II. The system remains high-efficiency and high-precision when treating 80℃ hot water, which effectively saves the cooling and heat exchange facilities of the boilers, and is energy-saving as well.

III. Thanks to the application of Bidun oil removal equipment, the valuable steam condensation water can be completely recovered and is used for the boilers again, while it had to be discharged for over oil content in the past.

IV. The system is not only energy-saving, but also environment protective as the oil content in water is separated, recovered and reused.

V. The operational performance proves that the 'blocking' technology Bidun oil removal equipment is applying is more advanced than the traditional 'mechanical' and 'absorptive' approaches in terms of oil removal mechanism, effect, precision, techniques, operation and environmental protection etc.

We hereby extend our sincere gratitude to Nanjing Bidun Environmental Protection Equipment Co., Ltd.

Report 2

We bought Bidun HY50BR High-Efficiency Oil/Water Separation and Respective Recovery System with the treatment capability is 100 ton/hr two years and five months ago. The operation proves that:

I. Bidun HY series oil/water separation equipment is the first to adopt the new 'blocking' oil removal technology, which completely solves the problem of the recovery of oil-containing condensation water. The effect reaches the international level.

II. 'Blocking' is substantially more advanced than the traditional 'absorptive' approach. The system is high-efficiency and high-precision, and the oil content of treated water is controlled under 0.3mg/l, which conforms to the national standard on oil content of inlet water for steam boilers.

III. No chemical additive and counter-flushing is needed during the normal operation of the equipment. The function is stable, and the operation and management are quite convenient, so the system is greatly welcomed and highly praised by the operators.

IV. The system has strong capability of high oil content (e.g. 1000mg/l) shock resistance. The outlet water meets the set standard.

V. The separated oil and water are recycled respectively, so is economically beneficial in terms of energy and water saving, and is environment protective as well.
