Oct 24, 2014 Biofilms in HDPE pipes were thickest but the total number of bacteria was the highest in PEX (1.24 × 10 7 cm 2). Extended biofilms on HDPE pipes may be a source of potentially pathogenic and opportunistic bacteria such as P. aeruginosa or Acinetobacter sp. which were found on this material using culturable methods.[price]PVC, the Poison Plastic[hdpe]Heres how you can help todayEncourage your school to renovate or build their school with PVC free building materials such as PVC free linoleum flooring and TPO roofing.
