Safbon DAF is Delivering to Desalination Plant of Dubai HAYSSAN Power Plant

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.

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.

Ceramic UF in Electroplating Wastewater Treatment Achieves Outstanding Results

Sep. 12th, 2018

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.

image.png

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.


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:

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.

image.png

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.

image.pngimage.png

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.

image.png

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.
