Biomass Production Potent. of Products in contact with Drinking Water Год выпуска: 2013Автор: European Commission European Commission and Joint Research Centre Joint Research CentreИздательство: Dictus PublishingСтраниц: 64ISBN: 9783845454276Описание In the framework of the European Acceptance Scheme for approval and certification of products in contacts with drinking water, the Biomass Production Potential (BPP) test for assessment the microbial growth support properties of these products has been harmonized, funded mainly by EC. The objectives of this study were to elucidate the BPP procedure and evaluate the growth promoting properties of selected pipe materials. The tested pipe materials showed large differences in their microbial growth support potential and the BPP values can be ranked: glass < Cu < SS < PP < PEx < PE < PVCp. The tested materials differed in the contribution of attached (biofilm) biomass to the total BPP. Materials characterized by a high BPP value and a relative lower ratio between attached biomass and total BPP have a higher potential to impair drinking water quality.

Юлия Добрый день, Юля! Я сегодня защитила диплом после вашего сопровождения на отлично :-) Хотела сказать Вам ОГРОМНОЕ спасибо за помощь! Вы мне помогали с сопровождением курсовых работ на протяжении всего срока моего обучения. Без Вашего участия мне было бы в сто раз труднее, ведь я работаю и времени на сопровождение курсовых и диплома всегда катастрофически не хватало. Так что в том, что я закончила этот университет есть большая доля и вашего участия. Ещё раз огромное Вам за это спасибо! Будьте счастливы и удачи Вам! При случае, буду рекомендовать Вас своим знакомым, кому понадобятся подобные услуги ;-)
