Despite the presence of about 58% inorganic matter in the substrate, a high rate of hydrolysis and subsequent acid formation could be achieved in an acidogenic reactor which was inoculated with rumen microorganisms. Degradation efficiency of neutral detergent fibre amounted to 62% at high loading rate (34·2 g volatile solids per litre per day) and short solid retention time (51 h). In order to study the effect of accumulation of inorganic matter in the reactor, degradation efficiency was studied at various loading rates and solid retention times. An increase of solid retention time to 74 h resulted in a decreased degradation efficiency, probably due to an increased ash content in the reactor under these conditions. The effect of inorganic matter accumulation was also studied after coupling of the rumen derived acidogenic reactor to an upflow anaerobic sludge blanket-type methanogenic reactor. By using this two-stage digestion process an overall conversion of papermill sludge into biogas could be realized. The operation over about three months of the two-stage process was studied in terms of process stability, nutrient recycling and accumulation of inorganic matter.</p></div>","PeriodicalId":100177,"journal":{"name":"Biological Wastes","volume":"32 3","pages":"Pages 169-179"},"PeriodicalIF":0.0,"publicationDate":"1990-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0269-7483(90)90046-U","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74452019","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the rotary screens previously employed to separate worms from vermicompost often became blinded, making worm separation slow and inefficient. An improved method was required. An experimental machine employing a novel combing action to achieve separation was therefore constructed and tested. The comb-type mechanical separator was shown to be effective with vermicomposts which were well-worked and had moisture contents of 80% wet basis or less. For example, using well-worked vermicompost derived from separated cattle solids and containing approximately 5 kg of worms/m<sup>3</sup> and with a moisture content (wet basis) of 75%, a throughput of 1·5 m<sup>3</sup>/h of vermicompost was possible, with a separation efficiency of 95%. Vermicomposting beds are sometimes maintained at moisture contents higher than 80% wet basis, and the degree of worm-working achieved can vary. Further work is therefore required to assess the performance of the comb-type separator over a wider range of conditions.</p></div>","PeriodicalId":100177,"journal":{"name":"Biological Wastes","volume":"33 1","pages":"Pages 25-37"},"PeriodicalIF":0.0,"publicationDate":"1990-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0269-7483(90)90119-D","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80981891","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
