  Publication

  • P. Wawrzyniak

  - Prace Studentów Politechniki Wrocławskiej. Seria : Konferencje - Year 2015

  From a mechanical point of view, the thickness profile of PET bottles manufactured by ISBM process is determined by mechanical and thermal response of blown preforms. From the microscopic point of view the biggest influence on the mechanical and thermal properties of PET bottles have orientation and crystallization processes. From a technological point of view, the thickness profile of PET bottles after manufacture by SBM process...

  - Polimery - Year 2020

  The hot fill process is an inexpensive conventional filling technology for high-acidity products (pH < 4.5). It allows certain drinks (sensitive beverages such as fruit and vegetable juices, nectars, soft drinks, vitaminized water) to be stored at ambient temperature without the need for chemical preservatives. The primary feature of the bottles used in the hot fill process is their temperature stability, i.e. the ability to retain...

  This paper summarizes the most significant steps in the activated sludge process development and recognizes key contributors. Recognition of the roles of oxygen and living organisms was the first step (1882-1914). Ardern and Lockett (1914) named the accumulated olids "activated sludge". The process was rapidly accepted and applied in the period 1914-1930. The most dramatic changes in the activated sludge process understanding and...

  Large quantities of water are used in car washing, so it is necessary to recycle the water, which is made possible by membrane filtration. FP100 (100 kDa) membranes have been used to treat car wash wastewater by ultrafiltration (UF). With time of operation, the properties of the membranes change. The membranes need to be cleaned periodically to prevent...
