I regret using the MBR membrane from this Chinese factory
“After five years of using the MBR membranes at the JX Purification plant in China, I regretted it. Because I found that after five years, they can be repaired and cleaned again for reuse”. My customer said. This saves them a lot of money and they can use them for another 2-3 years.
What is the history of MBR products in the world ?
In 1966, Dorr Oliver Company in the United States first used MBR for wastewater treatment research.
In 1968, Smith and others will be ultrafiltration membrane and aerobic activated sludge combined to form the MBR system.
In the 1970s, countries began the in-depth study of membrane bioreactor process.
In 1982, Canada's Zenon (Zenon) Environmental Corporation launched the ZenonGem commercialized products into the market.
In the early 1990s, the Japanese government to promote the "90's water reuse program", so that MBR technology in Japan to develop rapidly. During this period, Kubota introduced the submerged MBR flat panel module.
In the late 1990s, submerged MBR process technology gradually became mainstream.
I am also curious about when the MBR industry in China started and what changes it has gone through.
China's scientific and technological community began to introduce and study the MBR process in 1991-1995, and in 1998 the first 200T/D MBR process water reuse plant was built in Dalian. 2001, China launched the policy of membrane industrialization. 2003-2004, the application of MBR at the scale of thousands of tons per day began. In 2001, China launched a membrane industrialization policy, and in 2003-2004, MBRs with a capacity of several thousand tons per day began to be applied, mainly in the field of petrochemical wastewater treatment.
From 2006 to 2011, MBR projects with a scale of more than 10,000 tons per day began to be applied in both municipal and industrial wastewater treatment fields.
From 2011 to now, MBR projects of tens or even hundreds of thousands of tons per day have been widely used.
Next, I would like to introduce our factory, as one of the earliest batch of MBR membrane products in China. Our factory has a heavy responsibility. We have to maintain the quality of our products in a competitive environment, and we also have to consider all the costs of the company to reduce costs and increase efficiency. At the same time, we have to keep researching and developing new materials to face the future development and changes.
Our factory, JX PURIFICATION, was established in 2001, when our company's chairman joined the MBR membrane R&D business right after he graduated from the university, majoring in materials. The first ultrafiltration membrane in China came from the north of China.
People who have been in this industry should know more or less that Canada Zenon later sold the MBR products under the brand to GE, GE sold the products to SUEZ, SUEZ sold the products to the current VEOLIA.
In 2012, our factory started to research and develop the membrane filament that can match the 500D products. Since 2001, China started to launch the industrialization of membrane, and a lot of enterprises started to research and produce MBR membranes, and our factory is the earliest batch engaged in the production of membrane manufacturing. After 20 years of development. At present, the factory's membrane filament can be completely benchmarked against the 500D membrane filament, and the production of membrane sheets can completely replace the 500D membrane sheets. Just last year, we also designed and manufactured indirect aeration system, the product has been successfully applied in large-scale oil refineries, as well as end-users in the pesticide industry. The quality of the produced water meets the customer's requirements. The chat record below is the real feedback from customers.
Let's take a look at the performance of our membrane products applied in domestic wastewater projects after 5 years. Customers say: your membrane can still be used after five years, the boss let me take it to you to repair and clean again, your products are too durable!
Slight breakage of membrane filaments occurs.
The color of the membrane turned yellow.
However, the lamination condition of the membrane is still very good. There is no membrane removal.
The membrane product can continue to be cleaned, repaired and then reused.
Let's take a look at the membrane fiber of another brand.
The fiber covering part of the membrane surface has fallen off, and the product is no longer usable.
The image is from a real customer project site.
membrane filaments, and we all know that DuPont, 3M, DARKIN, they are all giants in the material industry, and it is only by mastering the materials that we can grasp the initiative. Our industrial development in China started late, fast development, the process will inevitably make some mistakes. For example, some factories have poor product quality and unstable quality. But the original intention of our factory is to make good materials and good products. Long-term stable development, to provide customers with stable quality, formula upgrade products. An order does not allow a factory has been the survival of stable development, the establishment of our own brand, to win the trust of more customers is the development of a long-term solution.
Our factory only started to do international marketing last year, and many of our customers don't know us, but there is an old Chinese saying that fragrant wine is not afraid of deep alley. So what products can we offer to our customers?
The first, a product of our own design, is simple and easy to install. The shape is also more common nowadays.
The second one is the membrane and membrane module that can replace Mitsubishi. It is also very popular in the market.
The third is 500D membranes and membrane assemblies, which only our factory can do as a replacement for indirect aeration. It is possible to place our membranes or membrane assemblies directly onto your current project. The size can be matched. The quality of water produced by membrane filaments meets the requirements.
We have some suggestions for those customers who have replacement needs.
1. First of all, you need to find the quality of membrane filament that can replace 500D, because the quality of membrane filament is the key issue. Membrane flux, membrane pore size. Tensile strength of the membrane. Our membrane is not inferior to 500D membrane from these three aspects. We have the test certificate from the authoritative organization. For customers with real needs, we provide free membrane filament for you and your customers to test.
2. Customers who have the need to replace the whole membrane module do not need to be obsessed with the size must be exactly the same. Frankly speaking, membrane module products are not machined parts products, all the dimensions must be seamless, as long as your membrane pool can be put down on the normal use. When you build your pool, the dimensions cannot be split hairs. Our width and length are the same as the 500D, only the height has a slight difference, but it does not affect the normal operation of the membrane module.
3. Looking for a certain strength of the factory, our factory can provide high quality service, efficient communication, if there are customers who have contacted me, you should know me, I am the head of the foreign trade department of the factory, I will give you professional service, so that you don't have to worry about the details of the transportation, packaging and so on. I will follow up your order from the beginning to the end and report to you. In addition, our factory can send professional engineers to the customer's site to guide the installation, operation and commissioning.
All is stainless pipes. More cost
