The Yuncheng second wastewater treatment plant phase II project of Safbon has been progressing smoothly since it was started on April 1, 2018. By the end of October, the construction of pipes and ditches in the civil and factory areas have been completed.
This project accommodates the coking wastewater in the industrial park, which has many toxic components, high salinity, high color and difficult biodegradation. The park is located in the Zhu-Zhaoxin river valley, in order to ensure the water quality of the entire trunk canal of the south-north water diversion project, Shandong section. In March 2018, the Heze government issued the strictest standards for industrial wastewater discharge in history: COD<30mg/l, total phosphorus concentration <0.3mg/l and ammonia nitrogen <2mg/l.
Faced with this challenge, Safbon has organized a core technical team who combined with the characteristics of coking wastewater, and conducted scientific evaluation and demonstration of the treatment process through a large number of field pilot tests and scientific experiment. Safbon finally effectively overcome the technical difficulties.
The expansion project is now under construction, and the commissioning of water supply is expected to start at the end of December. The completion and operation of the project will thoroughly solve the problem of coking wastewater treatment in the local industrial park, which will not only bring obvious environmental and social and economic benefits to the local area, but also play a positive role in water quality protection of the entire south-to-north water diversion project.

At the beginning of this year, Safbon undertook the DAF (Dissolved Air Flotation) equipment and related supporting work in the seawater desalination pretreatment of Dubai HAYSSAN 4 x 600MW coal-fired power plant. This project uses the DAF device Minicell, which is the DAF technology designated by the client, using the KWI third generation air dissolving device ADR.
Fig.1 KWI Dissolved Air Flotation equipment (Minicell+ADR)
The reason why the project uses DAF is mainly because the seawater in the Middle East contains algae. According to the operating experience of the FEWA authorities over the past ten years, there are different levels of microbial contamination in the desalination plants without DAF, resulting in a decrease of the life of RO membrane.

According to the requirements of the client, the DAF team customized the DAF equipment while maintaining the original civil construction funding plan. After many comparisons, the client finally insisted on using Safbon’s KWI DAF Minicell. The structure of the Minicell tank is relatively simple, easy to install and operate, and the algae removal rate is high, the land occupation meets the site requirements, and the water distribution is uniform. At the same time, with KWI's unique core patent technology - the air dissolving device ADR, it has the characteristics of high air dissolution efficiency, short retention time, not easy to block, uniform air bubbles in the water etc. The combination of the two can achieve a perfect treatment effect.
During the project execution phase, the technical team strictly controls the quality from design, material procurement, and equipment manufacturing to ensure that the equipment can meet client requirements. In design stage, the design engineer strives for excellence in design and multi-level review and optimization of engineering design drawings; in material procurement stage, the engineer purchases high-quality anti-corrosion stainless steel from overseas, and the wet part materials are all super duplex stainless steel; in manufacturing phase, experienced field engineers from Austria are assigned to supervise the workshop to ensure that the equipment meets the quality requirements at all stages of manufacture.

At present, the pretreatment of domestic electroplating wastewater mostly adopts two-stage pH adjustment + two-stage coagulation treatment-integrated wastewater coagulation-biochemistry, and the advanced oxidation process of concentrated water enters the biochemical treatment system, with long process flow, large dosage of fertilizer, and sludge volume ( Dangerous waste) causes high processing and operation costs, increased salt content during processing, and increased conductivity, which has a particularly large impact on the biochemical system.
This electroplating park used the MBR (organic film) process to shorten the process, reduce the floor space and provide stable effluent quality. But at the same time, it has brought new pain points to the enterprise. The organic film is easy to break and peel off the skin. The effluent brings out metal ions, the film is severely blocked, and the flux recovery after cleaning is poor, and the service life is short.
Safbon Water used the German ItN nano-coated ceramic flat film to conduct MBR pilot test in the electroplating park. ItN flat ceramic membrane is a ceramic body with a very uniform crystal phase formed by nano-coating material and ceramic membrane support after high-temperature sintering at more than one thousand degrees. Its unique nano-coating process has anti-stick and anti-clogging functions. It has been successfully operated for 12-16 years at the MBR project in the Peterborough WWTP in Germany and other projects in Europe and the Middle East.
The ceramic membrane has high mechanical strength and good chemical stability, and solves the problem of membrane breakage and running mud from the material itself. The water quality before the pilot test film contains various heavy metal ions, the COD is maintained at about 200, the pH is about 11, and the suspended matter is not precipitated. The ceramic membrane was run for 9 minutes, stopped for 1 minute, and backwashed every 30 minutes. By comparing the water quality indicators of the inlet and outlet water for 15 days, the suspended solids could not be detected, and the detection values of COD, copper ions, nickel ions, chromium ions and zinc ions reached the discharge standard of electroplating wastewater. The average flux of the flat ceramic membrane is maintained at 150 LMH, which is more than three times higher than the organic membrane flux. During the test, fouling will also occur during operation. By backwashing, the flux can be easily restored, and with regular drug washing and gas scrubbing, the system can be well maintained for a long time.
Through the success of this pilot test, the application prospect of German ItN ceramic ceramic membrane technology in electroplating wastewater treatment was verified. We are confident to provide perfect solutions for similar projects in China.

The treatment of landfill leachate is always the problem for the industry. As the national environmental policy continues to upgrade, the handling of this aspect also faces greater challenges.
The traditional landfill leachate treatment process usually adopts the biochemical recombination of anaerobic advanced oxidation and organic ultrafiltration membrane with multistage nanofiltration or reverse osmosis treatment. However, due to the complex composition of landfill leachate, the operation of organic ultrafiltration membrane is not stable, and the problems such as broken wires, peeling, fouling and difficult maintenance inevitably occur, resulting in the instability of ultrafiltration water. This affects the subsequent operation of nanofiltration and reverse osmosis, so the selection of ultrafiltration is crucial to the smooth operation of the whole process.
The German ItN ceramic flat membrane owned by Safbon can effectively avoid these problems of organic ultrafiltration membrane. Meanwhile, it has obvious advantages such as high flux, extremely long service life, high sludge concentration operation, low operation cost, low cleaning frequency and low dosage of chemicals.
At present, the pilot project of Safbon in cooperation with a large environmental protection group company is in progress. The treatment process of landfill leachate is advanced oxidation + nanometer ceramic flat membrane. After a month of operation, the facilities run well and the permeate quality is stable. The quality of landfill leachate raw water is as follows:
The permeate quality is stable to reach grade A discharge standard
Through this successful experiment, the Safbon has verified the feasibility and technical advantages of German ItN ceramic flat membrane in the treatment of landfill percolate, and we are confident to provide a complete solution for similar projects in China.
