With joint expert knowledge at the top
More than 20 years of experience as manufacturers of ceramic membranes and up-to-date manufacturing plants are the basis of our success. Nevertheless, our employees are crucial for our company.
We are proud to say that most of our employees have been working for atech innovations gmbh since its beginnings. Due to the fact that our company started as a plant engineering company we have in-depth know-how in this area. It is exactly this know-how that our customers can rely on, even today.
One example for joint expertise is the variety of our employees' professions: we have food technologists, chemical engineers, process technicians, ceramics engineers and materials engineers. Their knowledge covers extensive subject areas, which is needed to achieve production perfection in these areas. Whether we produce ceramic membranes for the food industry, for the biotechnological industry or for the chemical industry we exclusively rely on expert personnel.
To ensure that our production is always at the cutting edge of technology it is a matter of course for our people to regularly attend training courses several times per year. We are aware that we are working in a very sensitive area and therefore it is absolutely vital for us to always keep our expertise up to date. Without exception.
We develop, manufacture and install ceramic membranes that are suited for a wide variety of applications. Ceramic membranes are primarily used when polymer membranes reach their limits.
Due to their excellent material properties ceramic membranes ensure process stability and high availability levels. In addition, they do only require a little pre-treatment and a minimum of maintenance. Composite membranes are characterized by high water permeability within the channels. For reasons of fluidity and in regard of hygienic aspects all membrane channels in membranes made by us have a round configuration, without exception.
Compared with products from competitors, particularly polymer membranes, our ceramic membranes stand out due to their high chemical, thermal and mechanical strength. This ensures a long service life.
Depending on the requirements of each particular application, we offer a wide range of different membrane geometries: We will supply ceramic membranes with pore diameters that vary according to the type of material to be filtered or separated and the desired filtrate concentration.
The standard range includes single-channel and multi-channel membranes with various pore diameters suitable for ultra-filtration (starting at 5 kD) and micro-filtration (up to 1.2 µm). They are available in various lengths, up to the currently possible maximum length of 1,50 m, in order to provide as many replacement options as possible.
Compared with products from competitors, particularly polymer membranes, ceramic membranes made by atech stand out due to their high chemical, thermal and mechanical strength, ensuring a long service life. Consequently, membranes are primarily used when polymer membranes reach their limits. Due to their excellent material properties ceramic membranes ensure process stability, high availability levels, low pre-treatment requirements and minimum technical care. Compared with ceramic membranes made by other manufacturers the quality of atech membranes is significantly higher because they are produced without using any ceramic binders or other additives.
When choosing ceramic membranes made by atech you will benefit from:
- high pressure resistance (bursting strength)
- resistance to concentrated caustic solutions and acids
- possibility of backpulsing
- very high abrasion resistance
- trouble-free cleaning
- temperature stability
- high flux
During cross-flow filtration by means of ceramic membranes the medium to be filtered flows through the channels of the membrane support. All particles whose size exceeds the pore diameter of the membrane are retained. The particles/molecules build up in the concentrate. The filtrate permeates through the pores and is treated in subsequent process stages as required by the particular procedure.
99% purity - no exceptions
Choosing the right material is key for production quality. This is why we exclusively use aluminum oxide with a purity of 99% to make our ceramic supports. Compared with products from competitors, particularly polymer membranes, our ceramic membranes stand out due to their high chemical, thermal and mechanical strength, so that we can guarantee a long service life. This is the only way to come up to the demanding requirements of our customers without difficulties.
Quality assurance is not left to chance, neither. We keep reference samples of all lots that have been supplied to us and delivered by us to customers. In this manner we can always find out who supplied us with the relevant material. Most of our suppliers are European or US companies with whom we have entertained business relationships based on mutual trust for many years.
We are proud to be one of only four companies in the world that are authorized to apply the 3-A Symbol to their equipment.
3-A (Sanitary Standards, Inc.) is an independent organization dedicated to advancing equipment design for the food, beverage and pharmaceutical industries. This organization represents the interests of stakeholders who are committed to promoting food safety and the public health.
This authorization is another proof of the top quality of our modules and shows that it does not cause any trouble to us to supply customers from these industries with our products.
Manufacturing our ceramic membranes at such a high quality level without a properly thought-out quality assurance process is simply unimaginable. We use random sampling to determine if all quality standards have been met. If quality deviations are found we at once check the entire lot in order to exclude any defects.
Each membrane we manufacture has its unique serial number. Using this number we are able to track exactly who was involved in the manufacturing process of that particular membrane and where we purchased the material used. The unique serial number shows at a glance in which lot a particular membrane was manufactured who supplied the material.
We have many decades of experience with top quality materials, and our process technology has been thoroughly worked out over the years. As a result, our products are always state-of-the-art and make sure that the required quality of filtration will be achieved.
Our pressure vessels are additionally subjected to leakage tests to ensure that they are absolutely tight. Each product that leaves our manufacturing facilities has been tested. This is what makes up our thorough quality management system.
