Attended the Third Technical Conference of the Oil-Gas Filed Surface Engineering

In September 20th and 21th, the third technical conference of the oil-gas filed surface engineering was successfully held in Chengdu. SafBon representatives gave a magnificent speech at the conference about the Application of ItN Ceramic Flat MembraneCFMand Dissolved Air FlotationDAFin the Water Treatment Process.

Participants at the conference gave a high evaluation and appreciation to SafBon due to its introduction of international advanced technology and equipment and the independent research capability in the water treatment technology. In addition, participants showed great interests on SafBon’s core products and the complete water treatment solutions.

At the conference, the main theme is about SafBon’s technical products - ItN CFM and KWI DAF. When it comes to ItN CFM, it applies the most advanced Nano coated technology in this world with the advantages of excellent hydrophilicity and pollution resistance; CFM, compared with organic polymer film, owns better membrane flux, longer longevity, greater acid and alkali resistance and less energy consumption.  ItN CFM is mainly applied in municipal water treatment, wastewater treatment and industrial wastewater treatment and CFM has its great performance on the water reuse project and water treatment with complicated pollutants, fluctuated water quality, high temperature and oily wastewater.

For KWI DAF, it provides 12 various products with different specifications for particular conditions. Compare with clarifiers and general dissolved air flotations, KWI DAF has great advantages of excellent gas dissolving effect, higher hydraulic load, smaller area, higher water quality and less construction cost. In paper industry, municipal water industry and petrochemical industry, KWI DAF has already been applied successfully.

SafBon received great reputation at this conference and improved its popularity in oil-gas filed and petrochemical industry. After the speech at the conference, industry experts visited SafBon’s exhibition booth and sought cooperation with SafBon.

SafBon Gets into A Race for A Global Water Award
—— Vote for “Liupanshui Sponge City” project, vote for SafBon

We are proud to announce that the “Liupanshui Sponge City” project of Safbon is nominated for Water/Wastewater Project of the Year.Voting will open on 6th March 2017 to all eligible voting groups.

The ceremony held by GWI (Global Water Intelligence) will take place on the evening of 24th April 2017 at the beautiful Palacio de Ciebeles, Madrid, Spain.

For more details of the project, see more information below:

Liupanshui Sponge City, China    

What is it?
A pollution and stormwater management project covering a 23km stretch of the Shuicheng river in Liupanshui city in Western China, which has a population of around 5 million people.

Note: A“Sponge City” refers to a city where its urban underground water systemoperates like a sponge to absorb, store, leak and purify rainwater and releaseit for reuse when necessary.

Who is involved?

Shenzhen-listed project developer Shanghai Safbon Water Service has invested RMB1.7 billion ($250 million) and owns 100% of the project company. The owner of the project is the municipal government of Liupanshui.

What makes it special?

Since this pioneering project started in January 2015, the concept of the sponge city has swept across China, drawing billions of dollars of subsidy pledges from Beijing. Safbon installed a deepsewer below the river, pulling hazardous municipal and industrial wastewater downstream to a new 100,000m³/d treatment plant. Fourteen flap dams, a 15km retaining wall and two new artificial wetlands tackle flood risk, while simultaneously reducing dust and purifying water to allow wildlife to thrive.

Decades of industrial pollution development in the narrow Liupanshui valley had slashed the value of riverside real estate.Safbon's ambitious programme put water back at the heart of the city's cultural and economic life, returning a revenue source to the local government. The landscaped rainwater collection systems have transformed the aesthetic reputation of the city, which directed its July 2016 marathon along the new permeable riverside walkways.

A network of pumping stations and pipelines divert stormwater and secondary treated wastewater to replenish river flows in the dry season. Crucially, the reuse of up to 201 million m³ of water every year will allow the city to defer capital investment in new water supply sources.

The Biggest Application of CFM in Seawater Desalination Project
According to the feasibility study review meeting for Xianren Island Seawater Desalination project, it is decided that Ceramic Flat Membrane (CFM) filtration process would be used as the pretreatment for RO.

The production capacity of this project is 400,000 t/d. It will be divided into three phases (1st phase: 100,000 t/d, 2nd phase: 150,000 t/d, 3rd phase: 150,000 t/d). 

This project will be built by Safbon Water Service (Holding) Inc., Shanghai and Yingkou Longyun Oceanology & Exploiture Co., Ltd. The treatment capacity of the first phase is 220,000 t/d. This project will be so far the biggest seawater desalination project in which CFM will be applied.


The material of CFM is different from polymer membrane. It’s highly resistant against organic pollutants and oxidation. The lifetime and flux of CFM is 3-5 times and 2-10 times of polymer membrane, respectively. The chemical consumption and operational cost needed is 50% less. The working temperature is from 5-60 ℃. This is a big advantage compared with the polymer membrane which breaks down under low or high temperature. In addition, CFM is oxidation-resistant ,which means it can handle chemical cleaning or other strong oxidants.


How to use the CFM in a large scale seawater desalination project? 

The chairman of Safbon, Hilling Chang, and his team have thought about this innovative and creative idea for a long time. A pioneer has to have a strategic vision and an overall perspective and may have to pay a price. 

Fortunately, ItN has already had two big reference projects in Saudi Arabia. Both projects are deep groundwater treatment projects. One is 100,000 t/d and the other is 150,000 t/d. But do these two high-quality projects really have high economic value? This question has troubled the Safbon management team. To solve this question, Safbon has cooperated with a world-leading finance company, PWC, in a big seawater desalination project. By analyzing numerous financial models, it has been  found that CFM is more advantageous than polymer membrane (assuming the operational period is 25 years). Therefore, the application of CFM in seawater desalination is more economically favorable.

The cooperation with one of the four world-wide top consulting companies has answered the question persisted with Safbon engineers. The innovation of Safbon is not only the technical research and development, management innovation, but also the win-win cooperation model with the others. This result is very valuable for the application of CFM.

“A big project, driven by a big team and then the development of an industrial chain is promoted”. This will be the trend for Safbon’s development in the future.
