Client: MARKET LEADER IN THE WASTE WATER MANAGEMENT INDUSTRY IN HUNGARY
Location: JÁSZFÉNYSZARU - HUNGARY
Application sector: WASTE WATER TREATMENT PLANT
Objectives
The enlargement of the existing wastewater treatment plant of the town is part of a wider plan of enhancement of the water management system carried out by the Client. The renovation of the plant foresees the construction of two new buildings where the water disinfection is implemented. This concrete buildings’ construction for the enhancement of the capacity of the existing plant required chemically resistant structures in order to allow a safe access to the machinery. The environment in waste water treatment plants, even in open air areas, is chemically aggressive, as the purifying process is carried out by means of chemical additives. The end Customer required structurally and chemically resistant structures, as well as an easy installation in order to allow the other parts of the plant to work.
Solution
M.M. designed and produced new FRP structures, keeping in mind not only the safety of workers during installation and use - ensuring structural resistance to the elements while respecting the deformation limits in accordance with UNI EN ISO 14122 norms - but also the required flexibility for an easier adaptation to the site. The structures were designed, in fact, for different areas of the plant; in particular for the cyclator building M.M. produced parapets and a tailormade staircase. Therefore, the staircases have been designed as prefabricated modules, in order to reduce on-site operations. On the other hand, the parapets have been supplied in a “kit” mode, with readymade vertical posts and horizontal bars to be cut on site in order to obtain a tailor-made solution. The installer is part of M.M.’s qualified network: a group of companies that are able to install our FRP structures in an excellent way thanks to our technicians’ support, who assist them during every step of on-site installation. In fact, for this project, M.M. provided not only the 2-D detail drawings supported by structural calculations, especially concerning the custom-made system which supports the staircase, but also remote support for the perfect installation of the parapets. Concerning the gratings, their concave antiskid meniscus top features a R13 V10 level of the DIN 51130 norm: therefore, the gratings are certified as non-slippery surface, even in wet conditions.
