Odor and Voc Removal from Wastewater Treatment Plant Headworks Ventilation Air Using a Biofilter
Laboratory scale experiments and field studies were performed to evaluate the feasibility of biofilters for sequential removal of H2S and VOCs from wastewater treatment plant waste air. The biofilter was designed for spatially separated removal of pollutants in order to mitigate effects of acid production resulting from H2S oxidation. The inlet section of the upflow units was designated for H2S...
متن کاملLivestock Air Treatment Using Pva‐coated Powdered Activated Carbon Biofilter
This study evaluated the efficacy of polyvinyl alcohol (PVA)‐coated powdered activated carbon particles as a biofiltration medium. This material exhibited excellent properties as a biofiltration medium with a water holding capacity of 1.39 g H2O/g‐dry PVA; wet porosity of 0.53; and significantly lower pressure drop than that of commonly reported biofilter media such as compost. Bench‐scale biof...
متن کاملBiotreatment of H2S- and NH3-containing waste gases by co-immobilized cells biofilter.
Gas mixture of H2S and NH3 in this study has been the focus in the research area concerning gases generated from the animal husbandry and the anaerobic wastewater lagoons used for their treatment. A specific microflora (mixture of Thiobacillus thioparus CH11 for H2S and Nitrosomonas europaea for NH3) was immobilized with Ca-alginate and packed inside a glass column to decompose H2S and NH3. The...
متن کاملحذف زیستی سولفید هیدروژنتوسط بیوفیلتری با بستر فوم پلی‌اورتان و فیبر نخل
Background and purpose:The emission of hydrogen sulfide (a malodorous and toxic pollutant) into the atmosphere is considered a public health concern due to its potential hazardous effects on human health. Therefore, the removal of hydrogen sulfide from polluted air streams is of paramount importance. This study aimed to evaluate the role of a polyurethane foam/palm fiber-based biofilter in the ...
