摘要:
The DPD titrimetric method for the determination of residual chlorine in water has been a standard laboratory procedure since its introduction in 1957. Over the years, the method has been extended by the addition of supplementary procedures.

摘要:
In a recent study, several field test kits for the determination of free available chlorine (FAC) were evaluated. In addition, modifications to the most promising test procedures were also evaluated. As a result, an improved method for the determination of FAC has been developed. This new procedure resulted from modification of the syringaldazine (liquid) procedure and is known as the free available chlorine test with syringaldazine (Facts).

摘要:
Spark‐source mass‐spectrographic analysis was used to characterize samples of alum‐coagulated sludge at the water‐treatment plant in Oak Ridge, Tenn. The sludge solids contained a heterogenous mixture of materials, including organic and nonorganic compounds, soil, and fly‐ash particulates. Analyses showed the presence of many elements.

摘要:
Discharging water‐treatment‐plant sludge into natural water courses is an unacceptable method of sludge disposal. The physical properties of sludge only add to the problem and increases the expense of tho complex process involved in rendering the sludge handleable. This article examines several methods of sludge dewatering and its ultimate disposal.
