Control of Bacterial Growths in Rapid Sand Filters
Nitrification has been observed in the rapid sand filters of many iron removal plants in Illinois. The biological oxidation of ammonia to nitrate by nitrifying organisms often results...

Manning n* for Cast-in-Place Concrete Pipe
Two-hundred eighty-one independent tests were made in irrigation cast-in-place pipelines during 1964-1966 in a cooperative program between the Salt River Project in Arizona and the United...

Factors Affecting Durability of Ferrous Metals in the Atmosphere
The corrosivity of the atmosphere in which a light gage ferrous metal is to be used must be considered. The corrosivity of unalloyed steel can vary through wide limits with a range as...

Iron-59 as Solids Tracer Aqueous Suspensions
A radioactive tracer is introduced for following the movement of particulate matter in sewage treatment processes. By combining this radio-tracer with dye tracers, the hydraulic characteristics...

Bin Loads
Silo and bin design is still largely an art because there is no rational and certain method to determine the loads exerted by the stored solid on the structure. In an attempt to rectify...

Precipitation of Iron in Aerated Ground Water
Efforts were made to determine the factors which govern the kinetics of iron precipitation so that a more rational approach could be applied to the engineering design of reaction basics...

Experimental Evaluation of Sand Filtration Theory
An experimental evaluation of sand filtration theory is presented. The mathematical model of filtration presented by K. J. Ives (University College, London) was evaluated by the filtration...

Foundation Behavior of Iron Ore Storage Yards
Field observations of twelve iron ore storage yards above plastic clay deposits demonstrate that, at least on overconsolidated clays, large progressive nonrecoverable movements are initiated...

Experiences with Ground Water on Construction
Unusual Canadian examples presented include control of groundwater at Steep Rock Iron Mines by trapping it before it reached drained lake bed; La Tuque hydroelectric development where...

Tentative Recommendations for the Design and Construction of Composite Beams and Girders for Buildings
The joint committee was organized in 1956 to prepare recommendations for the design and construction of structures composed of prefabricated beams combined with cast-in-place slabs. After...
