Hydraulic transport of ground refuse in existing sewer systems may be feasible only if both metals and glass are excluded, and a conventional collection of the nongrindable and bulky constituents of residential refuse will still be needed. The total 1973 cost of such a wet system is estimated at between –110 and –200 per household per year, of which –80-–105 is for grinding. This compares to a total cost for sewage and refuse collection and disposal under existing concepts of –40-–115 per household per year. If the cost of the grinder is excluded (individuals would purchase grinders), the 1973 wet system costs to the public sector would be on the order of –30-–90.","PeriodicalId":17335,"journal":{"name":"Journal of the Environmental Engineering Division","volume":"1 1","pages":"769-788"},"PeriodicalIF":0.0,"publicationDate":"1976-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89754796","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}

Irrigation rates from l in./week-4 in./week (25 mm/week-l00 mm/week) were used. Three cuttings of forage were obtained over a 2l-week growing period. Dry matter yields increased with irrigation rate, while dry matter percentage showed a decrease. Nutrient uptake generally increased with application rate, while recovery efficiency of all elements measured decreased. Recoveries of 67% and 50% of applied N occurred at l05 lb/acre (ll8 kg/ha) and 2l5 lb/acre (240kg/ha) for rye, and at 195 lb/acre (2l8 kg/ha) and 310 lb/acre (347 kg/ha) for ryegrass. The effluent was deficient in K relative to other nutrients. An irrigation rate of l in./week (25 mm/week) to 2 in./week (50 mm/week) appears suitable for production of rye or ryegrass with effluent on well-drained sandy soils.","PeriodicalId":17335,"journal":{"name":"Journal of the Environmental Engineering Division","volume":"21 1","pages":"475-483"},"PeriodicalIF":0.0,"publicationDate":"1976-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72720909","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}

It is questioned whether seeking an optimum solution to this problem is justified, given cost uncertainties, environmental impact questions, and other considerations. The programming techniques involve a considerable amount of mathematical sophistication. Modification of these programs by planning agencies for some alteration to the system would be extremely difficult, if not impossible. Secondly, most of the techniques require long computational times, resulting in added coasts and inefficient use of the computer. Finally, the programs have various flaws when trying to apply their technique to an actual situation.","PeriodicalId":17335,"journal":{"name":"Journal of the Environmental Engineering Division","volume":"16 1","pages":"233-237"},"PeriodicalIF":0.0,"publicationDate":"1976-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84209983","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}

The fate of these metals and the amount of annual transport to the ocean are evaluated, based on: (1) Concentrations of trace metals in the wastewater particulates; (2) sediment metal concentrations in the proximity of sewer outfalls; (3) the degree of metal release from wastewater particulates upon mixing and dilution with seawater under laboratory conditions; and (4) the settling velocity of sewage and sludge particulates. More than 90 percent of trace metals, such as cadmium, copper, lead, nickel, and zinc in the sludge particulates are solubilized through biochemical reactions. A higher degree of solubilization from the mixture of primary and secondary effluents is observed.","PeriodicalId":17335,"journal":{"name":"Journal of the Environmental Engineering Division","volume":"12 1","pages":"675-685"},"PeriodicalIF":0.0,"publicationDate":"1976-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77731188","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}
