| pubmed-article:14982039 | pubmed:abstractText | The aim of this paper is, from the perspective of improvement of Total Suspended Solids (TSS) measurement by UV spectrophotometry, to study the influence of two pretreatments on the UV responses of urban wastewater (sonication and mechanical grinding). The study of optical properties evolution the different phenomena involved and show mechanical grinding as a potential pre-treatment is prosed. Mechanical grinding is applied to samples characterised by different TSS concentration and particle size distributions in order to test its feasability. Results show the limit of the pretreatment and the difficulty of exploiting the UV response of urban wastewater for TSS characterization and estimation. | lld:pubmed |
