Celebrate Ceramic Success
16th September 2019
During a recent internal meeting we were discussing our new projects and I noticed that we are about to reach 100 installations. I thought about how we accomplished this in under a decade and that these installations treat about 39 MGD; I was impressed with our progress. In the Americas, where we are beginning to see more and more interest in ceramic membranes, we still hear people asking, “When will ceramic membranes be more commonplace?”. I thought perhaps the question is “How can we get our message out to the North American market about our successes?
For these projects, our membranes have been used in MBR and filtration applications in the Food & Beverage, Oil & Gas, Manufacturing, Municipal Water and Wastewater markets as well as others. End-users have selecting our membranes for various reasons like their strength and longevity, their ease of maintenance and recoverability, their value and yes-a lower life cycle cost then polymeric in some cases. One common reason has been our membranes' performance day in and day out on these various applications which I believe has helped us to grow our installation base.
See you there.

Ceramic Membranes Help with Metal Processing Wastewater
13th November 2018
Wastewater from metal fabrication can contain a variety of contaminants such as heavy metals, oil, grease, solvents, grit and fine metal particles. Even if you are fortunate enough to be able to discharge it to the local municipal wastewater facility it can still be quite costly, and the treatment process can be complicated. Solving this dilemma can add to your bottom line, not to mention eliminate the headaches associated with your wastewater, allowing you to focus on your metal processing.
Regardless of the overall treatment process, it is likely that a liquid-solids separation or filtration process will be required as part of the solution. To ensure consistent effluent or reuse quality, the use of MF/UF (micro filtration/ultra-filtration) membranes comes to mind. When we consider the nature of the contaminants, most membranes are not a viable option. Oil, grease and fine metal particles can irreversible foul or even damage polymeric membranes.
At Meiden, we target difficult wastewaters’ liquid/solids separation requirements with our ceramic flat-sheet membrane (CFM). The oily and abrasive wastewater does not pose the same risks for our membrane and it can be the best decision. Here are some examples of facilities that successfully implemented our CFM.
Auto Bearing Manufacturer – This metal processing facility deals with a difficult wastewater containing high COD (chemical oxygen demand) (6-7,000 mg/l), petroleum oil and grease, and metal fines. Even though the capacity was small (50 m3/day), reuse became a more economically viable option than discharge. In order to reuse the wastewater, it was determined that ion-exchange (IX) would be the final polishing treatment process.
The DAF (dissolved air floatation) removes some oil and reduces the COD feed to the MBR (membrane bio reactor) to around 2,000 mg/l. The ceramic MBR provides consistent high-quality feed water to the activated carbon and IX.
Motorcycle Parts Finishing – This facility creates a difficult wastewater from its parts cleaning and painting process. The oily wastewater with metal fines led the client to the process using coagulation sedimentation and DAF to try to pretreat the wastewater for the final treatment using A/O (advanced oxidation), MBR and RO (reverse osmosis) to polish the water for reuse back in the facility. Several steps allow for a consistent treatment quality. The CFM membrane provides the robust and reliable barrier to the oil and metal fines to protect the RO.
In some cases, your goal is only to reduce the high COD to meet a discharge limit to the Municipal WWTP.
Hardware Parts – This facility manufactured parts by metal cutting and polishing. Their wastewater was high in COD containing oil and metal fines. To meet their lower COD discharge limit they employed a process using our CFM membrane to reduce the COD by 60% with filtration alone.
Thanks for checking out this blog and we hope you follow us to see other past and future blogs. Whatever your filtration application, you should consider our ceramic membrane to provide you with a stress-free membrane so you can focus on your business. Contact us to discuss how we might fit into a treatment process for your wastewater.

Don’t get lost in the F.O.G!
26th June 2018
The food manufacturing business has morphed over recent years due to an uptick in processed foods and smaller facilities entering the market with niche products. With the growth swing in the industry, there have been more stringent regulations focused on the manufacturing processes and greater responsibility is required for their manufacturing by-products. More and more food manufacturers are responsible for their own wastewater, but they would rather focus on their business. And, since “wastewater” and “food” don’t go together like peanut butter and jelly – most facilities only scratch the surface of how their wastewater cannot only be responsibly dealt with but in some cases used to improve their bottom line.
These manufacturers have implemented MBR technology, with its small space requirements yet handling their challenging wastewater. One aspect attracting these facilities to our ceramic membrane technology was the reduced operational risks. Our ceramic membrane provides the ability to handle challenging wastewater constituents and process upsets and yet recover with relative ease. This has allowed these food manufacturers to focus more on their business and not their wastewater.
MF/UF membranes provide a barrier to all particulates equal to or greater than their pore size. They cannot discriminate when F.O.G. is present and the membrane will capture it. The very nature of F.O.G. can create a real challenge to keep it from clogging the membranes surface. F.O.G. can cause membranes to have premature fouling and result in frequent and in some cases difficult cleanings, creating a serious maintenance challenge. In the food processing and restaurant waste facilities where we are installed, our membrane has demonstrated its ability to successfully recover in high F.O.G. environments using standard cleaning practices. At the upcoming AMTA Workshop in Spokane Washington, we will discuss one of our wastewater treating successes at a meat processing facility where the F.O.G. is extremely high (up to 1000 mg/l). We will share some operational data from our two years of operations while demonstrating how we successfully handle F.O.G. and have yet to require a CIP.

World Water Day 2018
21st March 2018
Last year was Meiden’s 120th anniversary year. This is no small feat for a company to reach this milestone. I think it is a testament to our philosophy of commitment to the communities that we serve. Our determination is inherited from our founder and the hopes of all of my colleagues.
Our main business is the manufacturing of electrical technologies that make, send, change, move, and control energy. For our long-term success we have heeded the changing requirements of society and this is particularly evident in our focused commitment to the environment. Our involvement in renewable energy production, energy saving technologies, electric and hybrid vehicles, and energy management systems to maximize efficiency is cutting edge. My group is involved with a product not related to electricity; our Ceramic Flat-sheet Membrane (CFM). This product was born from our knowledge of ceramic manufacturing and our clients’ desire for an innovative water filtration technology.
Our CFM quite simply filters particulates from liquids, mainly water. We developed this technology about a decade ago after considering the success of polymeric membranes yet recognizing the need to address their shortcomings. Over this time we have worked with our clients to provide about 34 million gallons per day of safe drinking water and reuse quality water by filtering both fresh waters and wastewaters in many different applications. We have helped clients meet their water needs in Japan, Singapore, China, Saudi Arabia, North America, and the list continues to grow.
Being green or sustainable is no longer just a buzzword as more and more municipalities and industrial clients discover that it can add to their bottom line. To get more solutions implemented that help combat climate change and protect the environment, it is critical to show that the solutions are economically viable.
Our clients have selected our CFM for different reasons such as;
- Lower lifecycle costs because of long membrane life
- Peace of mind due to high recoverability
- Easier membrane maintenance
- Value added to their water needs and uses
- Ability to treat difficult waters cost effectively
Their applications have ranged from; treating surface or ground waters to safe drinking water, treating municipal wastewater in a membrane bioreactor (MBR) configuration as part of a reuse scheme, or treating industrial wastewaters in both MBR or filtration configurations for proper discharge or reuse in the industrial facility. We use the expression ONE WATER – ONE MEMBRANE.
I hope that we’ve shared our positive outlook as we continue to evolve and meet the water challenges we now face. We are one piece of the puzzle. There is an army of people, products, and solutions both ready to meet the challenges today and in development to help us better meet them in the future. We are proud to be part of this army.
Thanks for your time. Please look for future blogs that will provide more details about benefits our CFM provides for specific applications and successful solutions that our clients have implemented by using our membrane.
In the meantime, consider a few of the many organizations that make a difference-even if it is just one glass or one tree at a time. Let's work together to address our challenges.
