ItN Ceramic UF Membrane Successfully Applied in Landfill Leachate Treatment Pilot

Sep. 10th, 2018


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.

Rio Grande do Sul Mayor Visited SafBon with Political and Business Representatives

Jul. 22th, 2018

On July 20th, the president of Brazil-China International Development Chamber of Commerce led a delegation to visit SafBon, Shanghai, including the mayor and other political and business leaders from Rio Grande do Sul, Brazil. The two sides conducted in-depth exchanges on water resources, water treatment and other environmental and ecological aspects.


The state of Rio Grande do Sul is the southernmost state in Brazil. It borders the Atlantic Ocean in the east, Argentina in the west and Uruguay in the south. Rio Grande do Sul, with an area of 280 thousand square kilometers and 497 cities, is the first agricultural and pastoral area in Brazil. The industry there is mainly composed of textile, food, tannery, tobacco, chemistry, metallurgy, machinery, shipbuilding, coal mining and sawing wood. There are some great ports and railroads connecting to the major cities in south-east Sao Paulo and Uruguay.

During the meeting, SafBon introduced the core technology in water supply, sewage treatment and solid waste treatment to the Brazilian delegation. SafBon is a comprehensive service provider specializing in intelligent and all-round technical solutions for municipal water treatment, seawater desalination, industrial water treatment, solid waste treatment and energy application. Upholding the concept of " Devoting to water business and improving our environment", SafBon conducts technology development, system design, system integration, system installation and commission as well as undertakes EPC turn-key projects, PPP, BT and BOT projects in all the relative fields. In recent years, SafBon has successively acquired the Austrian company KWI, the German company ItN, the American company SWT, and the Swedish company AquaSwiss, gradually forming a global layout. The companies mentioned above are the originator of air flotation, the pioneer of flat ceramic ultrafiltration membrane and the overall solution providers, respectively. Through the integration of global resources, SafBon is also actively developing markets in Latin America, such as Costa Rica, Peru, Columbia and other countries, including PPP, BOT and EPC/EPCF projects of municipal water treatment and so on.


The unique green water desalination technology of SafBon can effectively improve the life of the reverse osmosis membrane and protect its operation, combined with Austrian air floatation and the pretreatment of the German ceramic plate ultrafiltration membrane. It can greatly reduce the electricity consumption and the chemicals consumption, increasing the recovery of fresh water.

Romario Rasaldo, a representative of Brazil's MPA alliance, and Nelson Morelli, a representative of CONTAC CUT which is Brazil's largest food industry and workers union, said they were impressed by the country's rapid development in economy and technologies of environmental protection during the visit. Brazil is in great need of world-leading water treatment technologies provided by excellent companies like SafBon. There is no seawater desalination technology in Brazil. The green water desalination technology can solve the problem of water use, replace the water diversion project, and effectively solve the local problems of agricultural water use.

China is the largest trade partner of Brazil, and Brazil is the largest trade partner of China in Latin America, too. China and Brazil have established the China-Brazil Capacity Cooperation Fund and China-Latin America Cooperation Fund to provide financial support for Brazil's infrastructure construction, people's livelihood projects and major trade. SafBon hopes to help local people solve environmental and ecological problems such as water use through exchanges and cooperation in environmental protection, and jointly promote the development of China and Brazil.


ItN Ceramic Membrane Enters the MBR Field for Produced Water Treatment

Jul. 18th, 2018

Recently, SafBon, together with German ItN ceramic flat membrane, participated in the open bidding for the MBR process segment of the ceramic flat membrane deep treatment project produced by SINOPEC Puguang gas field, and won the bid as the first candidate. It will also successfully sign a contract to become the online supplier of SINOPEC through this project.


Puguang gas field is one of the three major onshore gas fields in China. The designed water amount of the project for the recovery of water depth in this gas field is 1440m3/d. The main water quality parameters are salinity ≤30000mg/L, Cl-≤15000mg/L, the content of sulfide is 8mg/L, and the total content of alkali is≤ 700mg/L, Ca2+ is ≤15mg/L, and Mg2+ is ≤15mg/L. Sludge concentration is ≤ 15000mg/L. The water quality has the characteristics of high salt, high corrosion and high concentration of sludge. It is a typical industrial waste water with high difficulty. Under these conditions, after nearly a year's argumentation and investigation, Safbon and the owner and the designer finally decided to choose the ceramic flat membrane in MBR.


As the first project of SINOPEC to apply the ceramic flat membrane in MBR to the deep recovery of the produced water in oil and gas fields, the bid of ba 'an water supplies has undoubtedly filled the gap in the domestic oil and gas field market in this field. This is also a breakthrough in the field of oil and gas fields after ItN membrane successfully signed the coal-chemical MBR project of China coal group in May this year. This project will give full play to the advantages of ItN ceramic membrane in anti-pollution, high flux, low operating cost and long life. Safbon intends to make this project into a sample project of ItN flat ceramic membrane in MBR water treatment of oil and gas field production which will open up a wide field of ceramic flat membrane in the field of water treatment in oil and gas fields and provide new impetus for environmental improvement in China.

ItN MBR Technology Succeeds in Pilot Test of Salt Chemical Wastewater Treatment

Jun. 15th, 2018

The treatment of wastewater from the salt chemical industrial area in Zhangshu City, Jiangxi Province is a chronic problem that has not been solved for many years. Under strict environmental protection supervision requirements, the local management committee requested technical assistance from SafBon. SafBon was asked to assist Zhangshu Salt Chemical Industry Park to solve the technical problem of wastewater discharge failure. Eucalyptus salt chemical wastewater has the characteristics of low BC ratio, poor biodegradability, high salt content and complex composition, and the upstream companies themselves have advanced oxidation treatment systems. Therefore, such water quality is extremely difficult to degrade COD wastewater. With the conventional biochemical system treatment, when the COD degradation rate is difficult to exceed 30%, even if the treatment load is reduced and the residence time of hydrolysis and acidification is increased, the COD degradation rate is difficult to reach 50%.


ItN Membrane Bioreactor

The membrane bioreactor (MBR) used in the pilot project is a fully automated small integrated device installed by the German ItN company. It uses a compact MBBR biofilm reactor as the front section and a ItN ceramic flat membrane MBR system as the latter, and constructs a flexible and changeable small biochemical reverse integrated system. The device combines the compound biochemical function of MBBR and the MBR high sludge load function together, with a full automatic control system, which can simulate a variety of process flow, including A-O, A2/O, A-O-A and so on.

In order to verify the universal high efficiency characteristics of the pilot plant, the technical personnel set the system process as the most common A2/O+MBBR, and set up a comprehensive and detailed test procedure, including single-machine commissioning, equipment clean water linkage debugging, low pollution Mud feed water commissioning, high sludge volume water commissioning, and debugging of different cleaning control methods. During the whole commissioning process, the maximum sludge concentration reached 7000mg/L, the average removal rate of COD was 51.3%, the total phosphorus removal rate was 63.8%, and the average removal rate of ammonia nitrogen was 95.3%. Although the target of the pilot plant in camphor tree is to degrade COD, the above data also show that it has good effect on ammonia nitrogen and total phosphorus in sewage.


Comparison of Inlet and Outflow of ItN Membrane Bioreactor

Through the success of this pilot project, SafBon confirmed the successful application of German ItN  ceramic membrane as a MBR technology in salt chemical wastewater treatment.
