Recently, SafBon has signed with China Coal Group Ordos Energy Chemical Co., Ltd. to apply German ItN nano coating ceramic flat membrane to its coal-to-methanol chemical wastewater treatment project, with the capacity of 9000m3/d, after multi-disciplinary approach made by technical experts of China Coal Group. It is expected that the installation, commissioning and steady operation of the MBR project will be completed by the end of this year.

ItN ceramic ultrafiltration(UF) membrane has the advantages of high flux, excellent anti-fouling, low energy consumption, long lifetime, small footprint, automatic system control, easy installation and operation, which makes it particularly suitable for the treatment of industrial waste water such as coal chemical wastewater. 

This is the expansion and optimization design project of China Coal Eenergy, which requires that the existing water treatment facilities do not increase land occupation, while the water treatment capacity and effluent quality requirement of the second phase of 1 million tons of methanol project are doubled. Since the first contact in the end of last year, China Coal Eenergy has been attracted by ItN Ceramic UF Membrane’s unique advantages, such as high throughput, high water quality, long service life of up to 25 years, and in-situ chemical cleaning (no lifting required). After four months of technical exchange and expert demonstration process, SafBon and China Coal Energy have reached an agreement and it is expected that the installation, commissioning and stable operation phases of MBR membrane units will be completed before the end of this year.

Coal chemical wastewater is one of industrial refractory wastewaters. It has characteristics such as complex types of pollution, high concentration, hard biodegradability, and large fluctuations in raw water quality. Membrane treatment processes cannot normally run smoothly without proper system design and membrane product selection. The expanded biochemical unit adopts its patented EBA combination process. The MBR unit adopts German ItN nano-plate ceramic membrane. The process can be described as a combination of advanced technologies, and it provides stable and low-cost operation for China Coal Energy.

The implementation of this project will fully demonstrate the application advantages of ItN ceramic membrane and create a new era of ceramic MBR membrane in the coal chemical wastewater and similar refractory industrial wastewater treatment fields, providing new impetus for China's environmental improvement.
