The membranes are used in various purposes in the industrial processes. They are usually attached to the machines or machine elements as a part of process, where particles are being removed using the membranes with adequate dimensions and density. In this case, membranes are a part of the industrial process and as such, their application is inseparable part of this process.

It is natural that this kind of procedure leaves some fouling behind, which may significantly reduce the function and the efficiency of the membrane used in the process. Due to impurities that are held on to the membranes, the operation can be seriously harmed which reduces or even eliminates the possibility of a successful production cycle. Furthermore, this improper function of the membrane can harm the rest of the elements in the machine used in the process, which can lead up to great costs and losses for the production, as well as to imminent delay of the production cycle.

This is why the usage of membrane cleaning process has to be applied as an essential part of the production and operation of the machine. Mbr cleaner offers a possibility to remove the impurities caught up at the membrane, on either of its ends, in order to maintain the efficiency of the membrane for the next production cycle.

The process of cleaning has to be professionally conducted in order to make sure that it was successfully, which will ensure the proper and effective usage of the membrane in the future. The frequency of the cleaning process depends on many factors.

First of all, the scale of production will have a great influence on the frequency of membrane cleaning. If a lot of production processes are completed within a short time period, membranes are more likely to accumulate impurities, so the cleaning has to be more frequent.

The composition of the substances used in the process and going through the membrane will also affect the frequency at which membranes need cleaning. Some chemicals and solutions might leave hardly any impurities which will naturally increase the time period one membrane can be used without the need to be cleaned. On the other hand, if there are a lot of particles to be removed from the particular solution in the process of production, membranes will become foul much sooner, which will demand thorough removal of those particles.

Another factor that will influence the frequency of cleaning is the type of membrane. Membranes are usually made for a specific purpose, to be used on the specific machine and in the certain processes. As a result, membranes are adapted to that process and machine, so there are different types of membrane that can be used, depending on the type of machine and production. Different types of membranes have different features, such as size, density, etc. which all affect the time interval during which they can function normally and efficiently, after which they have to be treated in the cleaning process in order to maximize their efficiency.

The University of Barcelona, Universidad de Barcelona in Spanish, is a public university in this city. There are over 60 thousands students enrolled at this university, studying one of the programs from undergraduate, graduate and doctorate program groups.

Founded under the request of Alfonso V of Aragon, the University is the result of medical school that was established in Barcelona, back in the end of fourteenth century. This medical school was also called Estudi General, but it was not officially recognized.

Over the years, the University has been through a lot of changes, as the situation in the country has greatly influence all of the public institutions. The University has even been closed for almost fifty years, but it was restored in 1837. Since the University was expanding, a new building was constructed in 1882. In 1970, that building was declared a national monument of historic and artistic interest. Hospital of Santa Creu i Sant Pau housed the medical science student.

Due to the large expansion of the University, additional buildings and facilities had to be constructed during the 20th century, most of which are in the university district of Pedralbes, which also known as the Pedralbes Campus.

Nowadays, the University of Barcelona is comprised of 18 faculties and 100 departments. Departments allow students to study various different topics including law, mathematics, medicine, geology, etc. Graduate programs allow students to obtain master’s degree in various different subjects, including master design Barcelona, master of psychology, etc.

The University of Barcelona is also an important place of research, since 30 research centers are available at this University. Research foundations include the Barcelona Science Park Foundation (PCB), the Bellvitge Institute for Biomedical Research (IDIBELL) and many others.

The University of Barcelona is considered to be one of the oldest universities in the world, with a long tradition and lots of notable alumni that attended the University at some point.

Although San Sebastian is considered a perfect destination for vacation, due to the mild climate, beautiful beaches and lovely nature surrounding it, this city has so much to offer when it comes to its culture and history. A perfect way to explore those is to go on a sightseeing tour of San Sebastian.

It is believed that the city of San Sebastian was founded around 1180 by the king Sancho el Mayor of Navarra. Due to the geographical location, the area of the city around Mount Urgull was used as a fortress where the castle was protected. Over the years, the city experienced several wars, and it was even occupied by the French for some time. After the Napoleon’s occupation in the beginning of the 19th century and the intense battle with troops from England and Portugal, the city has been completely destroyed and turned to ashes.

Those who survived where determined to rebuild the city, after which better times were ahead of San Sebastian city. The second half of the 19th century marked the beginning of the more prosperous times for the city and its inhabitants. Queen Isabel II visited the city and encouraged its development. In 1863 San Sebastian was named the capital of the Gipuzkoa province. The old fortress walls were demolished and the main activity of the locals became commerce. As the city developed, it turned to a popular tourist destination.

While you enjoy in the sightseeing tour of San Sebastian, you will visit some a lot of the places important as parts of history and culture. For example, you can visit Santa Catalina Bridge, Paseo Nuevo, Paseo de Francia, Calle Aldamar, Calle Miracruz, Avenida de Navarra, Avenida Zurriola, Zurriola Bridge, Plaza de Funicular, La Concha Bay, Calle de San Martin, Paseo de la Concha, etc.

There is no doubt that you will spend a lot of time Parte Vieja, the central part of the city. It used to be surrounded by walls, which were demolished as the reconstruction of the city began in 19th century. However, Parte Vieja is important because of the outstanding architecture which displays the influences of various styles and cultures. There are buildings where you can find San Sebastian apartment to rent in this part of the city. Two most important churches, the Santa Maria and San Vicente, are also in this part of the city.

If you want to learn even more about the Basque culture, it is recommended that you visit San Telmo Museoa. It is considered to be the oldest museum in San Sebastian, existing from the early 20th century. With several permanent and temporary collections, you will learn a lot about Basque culture and society.

Beautiful designs are very important nowadays, as they can attract attention and focus one’s mind to an object in question. The application of design is so vast that there is a constant need for designers in various different areas, starting from web design to designing of product packages or advertising messages.

What brought this idea of design thinking is the need to be noticed. As we live in consumer society, we are constantly overwhelmed with all sorts of advertisements, messages, information, etc. It is estimated that a person is exposed to over five thousands ads a day. Not only are people unable to fully grasp the message of each ad, but they are most likely to forget the ad quite soon.

In order to prevent this, companies struggle to find new ways of attracting people with visual elements. Since it is familiar that people are able to comprehend the message on an image much quicker, than if the same message was written, the modern world simply demands effective images and designs to be used in different areas of our lives.

Starting from the need to design a package for all sorts of products, such as cookies, make up or book cover, companies are working hard on finding new designs and creating a unique set of designs which could make a company be recognized. This certainly have a positive impact on marketing and helps a company to establish a connection with the consumers. Recognizable designs help companies build their reputation and to present their business in the best possible way.

When it comes to web design, this skill is something that almost every company needs if it wants to be successful at reaching consumers online. Airline companies, online stores, children playrooms, bookstores, etc. Everyone wants to be found online as consumers are oriented at online search, rather than walking and looking at the store windows. Well-designed websites, blogs, social media accounts, etc. are there to attract the attention of the online visitors with original, breath-taking designs.

We should not ignore clothing design as well. Just as in any other environments, design is a very important aspect of clothing industry. Perhaps this is where the creativity and original perspective have the most powerful effect. With so many types of fabrics, colors and accessorizes, opportunities for creating stunning designs are endless. The possibilities for combining are endless which allows us to make something new and fresh.

Design can help us communicate a message, to call for action, to express emotions, etc. This is an effective advertising tool, regardless of the area in which it has been applied. Designing is a process of creating something new, sharing your personal thoughts, seizing the moment of inspiration and capturing it into something concrete. This is a modern type of art that overcomes boundaries in all aspect and help us achieve various different goals, such as increasing sales and online position, or creating your personal line of clothes or accessorizes that feature a delightful style of yours.

A Conference in Madrid

Posted by loverblog on March 07, 2014
Madrid / No Comments

I have been working as a teacher for over fifteen years now, and I am very interested in new, innovative ways of learning and teaching. New technologies and different ways of communication and socialization impose some new challenges in both teaching and learning. This is way I am interested in learning about new methods that are applicable in the modern classroom, hoping those would produce best results.

Over the past few years, there have been lots of conferences and conventions about language teaching and learning, and I have tried to attend as many as I could. Not only have I learned about the latest improvements, suggestions and teaching methods, but I have also met teachers from different cities and different countries that face the same challenges as I do.

This kind of experience helped me a lot when it comes to teaching and working with students. It helped me understand the modern way of communication that might seem intimidating to the older generations, but is something almost innate to the younger generation. Having this in mind, I believe that the teaching process has to be adapted to fit the modern reality and to exploit the technology that is available.

Therefore, when I find out that Madrid will host the International Conference of Linguistics, Language Teaching and Learning, I have decided to apply. The conference will be held in a conference center at the end of this month. I do not believe that a two-day event would be enough to focus on all of the topics that should be dealt with, but it will certainly be a great opportunity to be a part of such an important event.

The goal of these kinds of conferences is to bring academic scientists, researches, linguists and educators to present and discuss the recent innovations and trends, as well as to talk about challenges we all encounter in this work. Experts in this field will speak about practical solutions that should help us overcome the challenges and use the situations in order to teach more effectively.

Besides the lectures, there will be presentations of researches conducted by respectable linguists and teachers. Their aim was to analyze the influence of the Internet and social media on teaching and learning. The international scientists and researchers have invested time into their studies, and they are eager to present their latest findings. Certain segments will certainly be devoted to general topics about the languages and how current situation affects the development of different languages. The influence of English is something that will definitely be discusses, as it has a great impact on all aspects of our lives.

I am really looking forward to this conference as it will enable me to take different opinions into consideration. This will also be a chance to learn about different experiences which ought to help me in my own work as I am constantly working on improving and advancing in professional sense. In addition, I will be able to meet some colleges from abroad.

MBR Technology

Posted by loverblog on December 21, 2013

MBR is short for membrane bioreactor. It refers to the process that combines microfiltration or ultrafiltration using membranes in the bioreactors. This process is widely used for wastewater treatment.

Bioreactors are devices or systems that are used for conduction of chemical processes which involve the usage or various substances. Organisms within the bioreactor are exposed to certain chemical process using the biochemically active substances. The substances react and create a chemical reaction that is supposed to affect the organism and create the desired outcome.

The chemical reactions inside the bioreactors are controlled by the adequate usage of certain chemicals that are inserted in the bioreactor. It is important that the balance of chemicals is planned in order to create the appropriate chemical reaction.

Anaerobic MBR is the process used for treatment within the bioreactor. Membrane technology enables advanced treatment of chemicals in order to cause the desired chemical reaction inside the bioreactor. The final goal is to treat substances in order to create solvents of certain chemical quality.

The usage of anaerobic MBR is an economical process as it enables membranes to be reused in the several processes. In this case, it is possible to save energy and reduce costs as a membrane will be efficient in several repeated cycles.

One of the main usage of anaerobic membranes is in the treatment of industrial wastewaters. Having in mind that the water supplies are getting scarce, it is evident that new solutions for preservation of existing water have to be introduced. Therefore, membranes offer a cost-effective solution that enables the energy recovery. The water can be used in several instances as the membranes inside the bioreactor will disinfect the water that has already been used in the process of production.

Membranes can be installed in the main vessel of the bioreactor or in the separate tank. Membranes that are installed inside the bioreactor are more isolated and more difficult to maintain, as the bioreactor has to be disassembled in order to access the membrane. However, this process of filtration is more effective if there is a constant fluid of the chemical, and especially if less surcharge is expected during the process of filtration. If the membranes are installed in a separate tank, they are not as isolated and they can be approached more easily. This type of installation is recommended when the expected biomass that is filtered in this process is significant. This enables the easier maintenance of membrane system.

Membrane fouling can have negative effect on the filtration process, as it may cause unplanned chemical reaction that would harm the components and the final product. This is why the process of efficient removal of the fouling layer from the membrane surface is extremely important for the successful process of water filtration. MBR technology is developing new ways to reduce the undesired effect that can affect the composition of the chemicals involved in the process. This would allow wide-spread application of this process as it would create optimal conditions for successful filtration process.
