On March 14, 2019, the 2018 Drainage Work Meeting of Sichuan Province cum Sewage Treatment Technology & Product Exchange Meeting was held in Shuangliu District, Chengdu. SafBon has brought our three core technologies and products to the conference, providing a green solution for the upgrading of wastewater treatment plant.
1. Phosphorus Removal & Sludge Concentration by Air Flotation
KWI is the inventor and leader of dissolved air flotation technology, which has invented 11 models of air flotation for different applications, during its 70 years development. Particularly, the application of KWI core technologies, the third-generation dissolved air system ADR and the U-shaped plate patented technology, allows the flotation equipment to operate under high hydraulic load and high sludge load. When using these technologies for phosphorus removal, the total phosphorus can be reduced to less than 0.05mg/L, and the problem of large land occupation in traditional processes can be solved. In terms of sludge concentration, the sludge can be concentrated at about 5% after the air flotation, which makes the sludge concentrator run more stably and the drug consumption reduced by about 30%.
2. KWI Filtration Technology
KWI’s floating filtration technology perfectly integrates air flotation and filtration. The equipment can be automatically backwashed one grid after another. Air floatation clarification and sand filter backwashing can be carried out at the same time. The quality of effluent is good, of which the turbidity is less than 0.5NTU and the algae removal rate is 99%. When using KWI activated sand filter cum continuous backwash filter, the hydraulic Load can be up to 18 m³/m2·h. Besides, the filter can run continuously without shutdown for backwashing. The denitrification deep bed filter’s operation integrates denitrification (nitrogen removal), phosphorus removal and suspended matters removal in the meantime.
3. Sludge Drying Technology
SafBon has the property right of the thin film sludge dryer, which can dry sludge with the steam from power plant. The dried sludge is transported to the power plant for power generation, fully meeting the concept of circular economy. The Qingpu sludge drying plant invested by SafBon adopts SafBon’s sludge drying technology in coordination with power generation, in which the thin film sludge dryers, independently developed by SafBon, are applied.
The implementation of "Water Pollutant Emission Standards in Minjiang River and Tuojiang River Basins in Sichuan Province" makes it necessary for wastewater treatment plants there to have an upgrading and reconstruction. The green solution provided by SafBon can perfectly prevents the SS, total nitrogen and total phosphorus of tail water exceeding the standards for wastewater treatment plants and solves the problems of sludge disposal. It will provide a solid foundation for Sichuan province to further implement the theory that lucid waters and lush mountains are invaluable assets put forward by General Secretary Xi Jinping, and win the battle of pollution prevention and control.

While many municipal sewage treatment plants are still worrying about the stability of Class A emissions, many provinces such as Zhejiang, Hunan, and Jiangsu have proposed quasi-four-category of water discharge standards. The introduction of high standard emission requirements is very different for the technical process routes introduced by various design institutes in China. This involves biochemical, physicochemical, membrane technology and advanced oxidation technology to deal with total phosphorus TP, total nitrogen TN, COD and other indicators. At the same time, it is necessary to consider the factors of land shortage, investment cost and operating cost of the existing sewage treatment plant, and it is necessary to conduct in-depth research and process comparison.
As China's economy is moving towards high-quality development and more provinces and cities have proposed that sewage treatment plant discharges meet quasi-four or ultra-clean emission standards, the high-quality voice of environmental protection equipment has begun to increase. As the saying goes, opportunities are always reserved for companies that are prepared. When SafBon acquired the KWI company in Austria a few years ago, many people expressed doubt and thought that traditional technology had no value. As the original company of DAF technology, KWI's intellectual property, patents and R&D personnel are a huge asset. Today, with a high degree of internationalization, it seems that SafBon is very visionary. We can no longer follow the old path of "introduction, digestion, and absorption" in the early days of Reform and Opening-up. Infringement and violation of patent laws have become unworkable. Nowadays, some companies are still enjoying it, and they are not relying on their own innovation to develop their business. This way, the road will be narrower and narrower. SafBon KWI’s DAF has the following advantages in the deep dephosphorization of municipal sewage plants:
1. Hydraulic load can be as high as 30 m3/(m2h)
2. Small footprint
3. The phosphorus removal effect is good, we can deep phosphorus removal to reach TP<0.05mg/L
To this end, we introduce the KWI’s DAF phosphorus removal process technology as follows:
1. U-shaped board patent technology, hydraulic load can be up to 30 m3/(m2h)
▲ Schematic Diagram of U-Shaped Board
2. ADR air dissolving reactor patent technology - to achieve the ultimate solid-liquid separation in the DAF tank.
▲ ADR Air Dissolving System (The Third Generation ADR Technology)
The process position of the DAF phosphorus removal process in the municipal sewage treatment plant is as follows:
In order to reflect the excellent performance of KWI DAF phosphorus removal, SafBon’s technology team obtained the following results through an on-site pilot test of about 8 months of a large municipal sewage treatment plant in a city in southern China.
When the hydraulic load is 25m3/(m2·h) and the reflux ratio is 20%, the effect of DAF phosphorus removal is shown in Table 1:
From the above data, it can be concluded that KWI’s DAF technology can achieve ultra-high hydraulic load and ultimate solid-liquid separation, breaking through the constraints on the “technology” and “land use” of the total phosphorus upgrading of sewage treatment plants, showing high efficiency DAF’s advantages of phosphorus removal. This lays a solid foundation for the promotion and application of KWI’s DAF in the municipal industry.

Since the acquisition of ItN in Germany, Safbon has successfully developed the square hole flat membrane through its own technological innovation ability, which is a contribution to the Germany ItN ceramic membrane family. At the same time, it also shows that the endogenous technological innovation ability of Safbon supply is improving!
In order to further improve the permeability of ceramic membrane and increase the membrane flux, the internal structure was optimized on the basis of maintaining the original shape. After further research and development, innovation and long-term test by technicians, we officially launched the square hole flat ceramic ultrafiltration membrane (the second generation of ceramic flat membrane). Now we officially announce that the second generation of flat ceramic ultrafiltration membrane of Safbon has been successfully produced and marketed in mass production. Compared with the first generation of round hole membrane, the filtration performance of square hole membrane is greatly improved, and the filtration efficiency is increased by more than 40%.
With the introduction of the second generation of ItN square hole ceramic flat membrane to the market, the first generation of round hole ceramic flat membrane products will gradually stop production within three months.
We can foresee that the ceramic flat membrane family of Safbon will introduce ceramic membrane device with high accumulation density in the next step to maintain the advanced nature of ItN ceramic membrane, so as to meet the market demand of water supply plant and sewage treatment plant MBR as well as oil and gas field water treatment. In addition, research and development of other new products is also under way.

Recently, KWI, the subsidiary of SafBon, took a 100,000 t/d advanced phosphorus removal upgrading project for sewage treatment plant in Xinjiang Province. This is the first large-scale advanced dephosphorization project for sewage treatment plant which applied dissolved air flotation (DAF) technology in China after KWI acquired by SafBon. It is laying a solid foundation for the promotion and application of KWI DAF in the municipal industry. At present, the project is under construction and is expected moving to operation stage in February next year.
The project applied four KWI-patented "U"-type MCH-100 DAF devices, which are equipped with KWI's third-generation patented high-efficiency dissolved gas reactor (ADR). A single DAF device is designed has 1,000m3/h processing capacity, its designed hydraulic load is 30m3/m2h, and the designed hydraulic retention time is <15min. The DAF is able to treat influent with 0.5-1mg/L total phosphorus while the effluent quality is designed with the total phosphorus ≤0.3mg/L and the suspended solids (SS) ≤10mg/L. The DAF and the ADR are made of SS316L stainless steel. The size of a single device ia: 12m (L) × 5m (W) × 3.5m (H). The entire project footprint is 35m × 15m. This project shows strong advantages of the KWI DAF, especially the small footprint and high efficiency.
The "U"-type MCH-100 DAF devices is KWI's newly developed rectangular air flotation equipment, which adopts the unique patented "U-shaped board" design concept. The principle is as shown in the figure. The raw water enters from the bottom of the DAF. Due to the special structure of “U-shaped plate” arranged horizontally, the water flows up along the outer side of the “U-shaped plate” and flows along the inside of the “U-shaped plate” to the clear water outlet. During this up and down flow, the contact time between the bubbles and the suspended particles is increased invisibly, and the coagulation flocculation effect of the particles is enhanced, and the microbubbles in the dissolved gas can quickly adhere to the suspended particles. Surface and drag it to the surface of the air bearing area. With such special design, the MCH-100 DAF devices obtains a high hydraulic load of 30 m/h, which greatly reduces the footprint of the floatation tank.

The Air Dissolving Reactor (ADR) is the core equipment of the KWI air flotation system and the latest generation of KWI's dissolving air. ADR uses KWI's proprietary technology to simply and efficiently dissolve air into the water to produce the pressurized dissolved water required for air flotation.
The Patented ADR
1. Up to 99% dissolved gas efficiency;
2. Stable micro-bubble particle size, which is not easy to be broken during the decompression release process, and at the same time can ensure a high rising flow rate;
3. The pressured gas is released directly through the pressure relief valve, does not require any auxiliary microporous release and dissolved gas release device. There is no clogging caused by corrosion and scaling, which will result in a decrease of the dissolved gas efficiency.
The Effects of KWI DAF
Because of the patent features of KWI DAF, its application is not limited to the traditional solid-liquid separation field. In addition to the application of deep dephosphorization in wastewater, KWI DAF is still used in the following applications with unique advantages:
1. For seawater desalination pretreatment and tap water: algae removal, removal rate 99%;
2. Residual biochemical sludge concentration: The concentration of concentrated sludge is up to 5%;
3. Clarification of filter backwash: the suspended solids of the effluent <10mg/L. Effectively tapping the processing capacity of existing sewage plants;
4. Oil Removal from oily sewage: oil content of effluent ≤ 5mg/L;
5. Fiber recycling in paper industry: Recycling of papermaking fibers without adding drugs;
6. Advanced sewage dephosphorization: Reducing total phosphorus from 0.5mg/L to <0.1mg/L
7. Concentration and clarification of sludge water in the water plant: suspended solids content of effluent <30mg/L, concentration of concentrated sludge >3%.
KWI DAF Series Devices
Based on the applications mentioned above, we have reason to believe that SafBon-KWI DAF will break people's limited understanding of traditional DAF with its unique advantages, and achieve international leading in the field of solid-liquid separation in various industries in China.
