Effects of design in single and multi-layered woven wire mesh combinations

Haver & Boecker OHG – Hall 8 – C13

Thinking things different and looking beyond standard lead to innovative design considerations in woven wire mesh combinations. In cooperation with the Institute of Mechanical Process Engineering in Stuttgart (IMVT) Haver & Boecker has investigated and evaluated different offline measurement techniques and particle systems and their influence on the result of the load-dependent fractional separation efficiency (FAG) and the dirt hold capacity when using woven wire mesh in solid-liquid separation. By means of a specifically selected gradient structure and layer orientation, the load-dependent fractional separation efficiency as well as the dirt holding capacity can be favorably influenced. This in turn has positive effects on the service life and efficiency of multi-layered metal wire mesh combinations in sintered and not sintered condition. Blocking tendency is significantly reduced. The throughput characteristics are optimized.

Benefits for use in filter components:
  • Reduction of blocking tendency and pressure loss.
  • Improved separation efficiency and dirt hold capacity.
  • Optimized throughput characteristics.

Automatic backwash filter turns legionella in cooling tower circuits off

Lenzing Filtration – Hall 7 – L12

Since the first attested Legionella outbreak in the US in 1965, there have been numerous cases of legionellosis all over the world with an average lethality of 1,500 deaths per year. One of the preferred breeding grounds for legionella bacteria are open cooling tower circuits. Corroded surfaces, fouling in the heat exchanger or the presence of microorganisms like ameba boost the growth while at the same time the evaporative cooling towers release the legionella bacteria in form of aerosol to the surrounding environment.
Fine filtration is able to eliminate fouling, prevents corrosion or the building of microorganism, whereas conventional media filters offer even more breeding ground in their inside or on its surfaces. Our patented Lenzing OptiFil®, however, is the only system that offers an all-in package. It filters with a fine filtration of down to 5μm and even below, 5% to 10% of process water installed in a side stream and reduces evidently the number of colony-forming units.
As an example, we may state a chemical plant in Europe that is operating several open cooling towers throughout its site. Some are without side stream filtration; some operate with media filters; one tower has our Lenzing OptiFil® installed. Although all cooling towers are below the governmental limits (which are becoming more and more strict) for colony-forming units, it is only the operating OptiFil® circuit that is even below the detection limit.

Test of respiratory masks – Better than the standard

Palas GmbH – Hall 8 – A11

The Palas® respiratory mask filter test rig PMFT 1000 allows a reliable control of the filter performance and enhances quality assurance. The current spread of the new corona virus CoVid-19 is leading to a massive increase in demand for respiratory masks worldwide. Manufacturers of filter media and respiratory masks are increasing their production capacities to the maximum. However, reliable protection is only offered by masks that have undergone special tests during production. To support manufacturers, Palas has introduced the newly developed PMFT 1000 respiratory mask filter test rig, which enables both quality assurance in production and product improvement in the development department.
A special advantage of the PMFT 1000 from Palas compared to other filter test rigs is that additionally to the penetration by mass, the exact representation of the separation per size class of the particles can be detected. Especially regarding the effectiveness of the breathing masks for the corona virus (size: approx. 120 nm – 160 nm), such an exact measurement of the particle size distribution is essential. The fractional efficiency is tested, e.g. the efficiency in the whole size range of 100 nm up to 5 μm (size range spectrometer 100 nm up to 40 μm*).
PMFT 1000 is future proof: It works with any kind of aerosol, it can be used for all kinds of face masks and is also easy to handle.

Automated device for changing pleating knives

Roth Composite Machinery GmbH – Hall 8 – A21

In the pleating machine industry ranges of pleat heights have been established in order to produce appropriate pleat heights from most varied materials. The two types of pleating knives being most frequently used are covering the ranges 5-50 mm and 10-100 mm.
Formerly machine operators had to remove protective guards and the bolts fixing the knives at the cross bars when having to change the range. Even for a machine width of up to 1000 mm it used to be quite difficult for one person to accomplish the change. For a working width of over 1000 mm it was mandatory to involve a second person. An additional potential problem was the challenge to assemble the knife perfectly parallel. Even experienced machine operators needed about 15 minutes to carry out the exchange.
Roth Composite Machinery has developed an automated device for changing the knives. The upper and lower cross bars are each equipped with two pleating knife ranges. The special drive techno logy of RCM machines makes it possible to swivel the knife crossbar by 180° and to change between the two pleat height ranges automatically. The whole procedure takes less than 30 seconds and can be performed during the production process (i. e. when having material in the machine) without any problems. As the knives do not have to be removed from the crossbars assembly faults will be prevented. Furthermore a referencing of the machine is not necessary.

Ceramic hot gas filters for the recovery of reusable materials in industry and agriculture

Fraunhofer Institute for Ceramic Technologies and Systems IKTS – Hall 7 – L2

Fraunhofer IKTS develops and improves materials and processes for hot gas filters and their applications, such as the dedusting of exhaust gases from the steel and lime industry. A further process development at IKTS focuses on the environmentally relevant topic of phosphorus recovery from the mono-combustion of sewage sludge:
By modifying the sewage sludge with special additives, the heavy metal load of the ash fractions-containing phosphate will be significantly reduced. The process is based on the targeted gene ra tion of volatile heavy metal compounds that pass into the gas phase at high temperatures and are separated from the combustion ash by hot gas filtration. The harsh conditions require the use of ceramic filters that are particularly resistant to high temperature as well as chemicals attacks. Realistic load situations can be simulated with special test benches in order to specifically improve the chemical and mechanical resistance as well as the filtration properties of the hot gas filters. In-situ modification makes it possible to reduce the specific energy consumption required for recovering valuable materials compared with processing the ash separately. By combining hot gas filtration with membrane-supported processes, it is also possible to extract CO2 from hot and dust-enriched exhaust gases to meet the emission regulations.

Antibacterial nanofiber HVAC filter media

HIFYBER – Hall 7 – K5

The proper filtration of circulating indoor air become more important because, today people spend more than 80% of their daily lives indoors and The HVAC systems are referred as the respiratory system of modern buildings. However, during HVAC operation, the microorganisms may obtain suitable environmental conditions such as temperature, moisture level and nutrient to grow and they can diffuse into the filter components in the form of bio-aerosols or accumulated dust and then spread into the indoors.
The emergence of the deadly virus Covid-19 points to the need to move the efficiency level of indoor ventilation systems to the next level. Bacteria or viruses do not move in the air on their own and are usually accumulated on dust, saliva or droplets. Airborne-sized particles were considered to be particles <5 μm in size and droplet-sized particles were considered to be particles >5 μm in size. Challenge controls are maintained at 1700 – 3000 colony-forming units with a mean particle size of 3.0 ± 0.3 μm at “Bacterial Filtration efficiency(BFE), EN 14683 Standard”. HIFYBER HVAC products at F7 level can hold more than 90% of 3 μm particles. It is also possible to increase the BFE to over 99% with HIFYBER HVAC products. SPP65-AB is an innovative product that combines nanofiber with antibacterial technology. In addition to its high pleatability, it has 4 times more air permeability at the F7 level than non-antibacterial and widely used glass fiber products.

Air hygiene plays a pivotal role in rail cars, as passengers and staff are continuously exposed to indoor air for extensive periods of time. The guideline VDI 6032 – Room Air Hygiene in Vehicle Interiors – sets minimum requirements for air quality in railways. It requires the use of inert materials in order to minimize metabolization by microorganisms.
To this end, the implementation of effective fire protection requirements is a fundamental obligation on all European railway networks. EUROSPEC requires the certification of all construction materials in rail cars that are acknowledged according to the European fire safety regulation EN 45545-2. By now, air filters failed to fulfill these requirements and could only selectively be used to the full extent of the requirements.
At the FILTECH Show DELBAG GmbH debuts its FireTex air filter series, as the first filter manufacturer to produce a full range of filter designs. Their range include from bag filters K85 FireTex for the filters class ePM1, FireTex filter mats and FireTex Z-Line filter cells. DELBAG’s entire FireTex air filter range is certified according to the European fire safety regulation EN 45545-2. All DELBAG ePM1 – ePM10 air filters are, needless to mention, subject to the supervision of the EUROVENT certification scheme and therefore, while being tightly checked for filter efficiency, DELBAG GmbH also documents an energy efficiency class for its entire ePM1 to ePM10 range of air filters.

Eco-filters: Automatic production process / Flexible automatic loader of endcaps for eco-filters production

AUTEC Automation • Gusbi SpA – Hall 8 – B26

The integration with AUTEC and GUSBI let to automate and have the production process under control from the loading of the paper to the unloading of finished products. The load of the media on the rotary table is automatically performed through the use of an anthropomorphic robot: the concentricity and the repeatability of the coupling of the paper with the endcap is ensured. The vertical press of the paper with the endcap is independent for each side of the filter. The load cells installed on the press allow to check each filter pressed; even the heating of the endcaps is controlled station by station setting the percentage of power for each single IR lamp and setting the height of the lamps. The load of the endcaps on the rotary table can be done automatically, with different solutions for loading the rotary table, with different level of automation and production autonomy. At the end of the production process the dimensional check is carried out automatically: a dimensional non-conformity is detected and the not compliance product is expelled from the unloading conveyor.

A new space-saving and flexible solution to load endcaps in the Gusbi table for the eco-oil filters production. A system that singularize and orientate the parts using our experience of drop-down conveyors joined with vibration system and vision camera. Easy to set up for model changes and new models.
