Diversion studies evaluated fish guidance to variously angled screen and louver arrays. A bypass system was designed by which diverted specimens can be returned safely to sea. Entrainment reduction studies with modeled intake structures led to development of a circular capped structure featuring uniform entrance velocity and a horizontal run prior to a vertical drop. Fish avoidance of various sounds was explored.","PeriodicalId":17335,"journal":{"name":"Journal of the Environmental Engineering Division","volume":"17 1","pages":"897-910"},"PeriodicalIF":0.0,"publicationDate":"1975-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74656533","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}

A linear programming model for screening the sizes and operating policies of conduits and storage and treatment facilities is formulated. The objective function is to minimize costs. The constraint set maintains physical continuity, sizes the facilities, and specifies water quality objectives. The paper also describes the EPA Storm Water Management Model, which is a detailed simulation model of combined sewer flows. The paper shows how the EPA model can be used interactively with the screening model to plan for the control of combined sewer overflow and local flooding. A case study is made on the Bloody Run Drainage Basin, Cincinnati, Ohio. The results of the case study indicate that the screening model and the planning method are reliable.","PeriodicalId":17335,"journal":{"name":"Journal of the Environmental Engineering Division","volume":"394 1","pages":"807-820"},"PeriodicalIF":0.0,"publicationDate":"1974-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74970386","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 conclusions of the Master Plan are based on extensive studies of existing facilities, present and future conditions, and the effects on the receiving waters of alternative plans. A real time computer based data acquisition system has been installed with 30 tipping bucket rain gages and 120 flow monitors with level gages. The Master Plan compares separate dry and wet weather improvements to combined facilities tied together with a computer based automated control system. Different treatment levels are utilized during dry weather. A variable range of storage-solids treatment combinations are utilized with split treatment during wet weather.","PeriodicalId":17335,"journal":{"name":"Journal of the Environmental Engineering Division","volume":"54 1","pages":"1013-1032"},"PeriodicalIF":0.0,"publicationDate":"1974-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76664346","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}

Lignin fractional removal of higher than 0.94 was obtained by using 40 mg/l of alum and 40 mg/l of quaternary ammonium compounds (as cetyldimethylbenzylammonium chloride) per 100 mg/l of lignin (as Indulin C). Initial pH values between 2 and 4 were found to be optimal. The superficial gas velocity should be controlled at some optimum value; for this research the value was 24.2 cm/min. Assuming a wastewater containing 100 mg/l of lignin (as Indulin C) is treated with 40 mg/l of alum and 63.3 mg/l of Arquad 2HT-75 (i.e., 40 mg/l as cetyldimethylbenzylammonium chloride) in a precipitate flotation system, the total treatment costs including chemicals would be $0.352/1,000 gal (or $0.093/1,000 l).","PeriodicalId":17335,"journal":{"name":"Journal of the Environmental Engineering Division","volume":"45 1","pages":"629-640"},"PeriodicalIF":0.0,"publicationDate":"1974-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76320736","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}
