Control analysis for water quality problem

Overflow Risk Analysis for Storm Water Quality Control Basins

The operational cycle of a storm water quality control basin can be divided into the waiting period between events and the filling and draining period during an event. In this study, an inherent overflow risk is defined as the probability of having a large event exceed the basin storage capacity. Such a probability is prescribed by the basin storage capacity and the local distribution of rainfa...

Man's control of water quality.

Man has certain needs for water: physiological, domestic, agricultural and industrial. These needs are not the same in quantity or quality, in location or in time, yet they must all be met to allow for mankind's full development. Man's use of water degrades its quality: by gross pollution, by residual materials which change the ecology of the water environment, and by persistent microchemical p...

Drinking water quality: new challenges for an old problem.

Quality control for SELDI analysis.

Surface-enhanced laser desorption/ionization time of flight mass spectrometry (SELDI TOF-MS) studies have claimed significant success in identifying biomarkers with higher sensitivity and specificity for detecting disease than currently available diagnostic methods (1–3). While these studies demonstrated great promise, the quality of SELDI spectra was not evaluated systematically until two year...

Water quality management of heavily contaminated urban rivers using water quality analysis simulation program

Precisely management of water quality in urban rivers is of significant and water environmental capacity provide a useful tool. This study presented a water quality analysis simulation program model-based approach for dynamical load reduction in Ashi River, highly contaminated tributaries of Songhua River, China. The actual and surplus dynamic environmental capacity of CODCr and NH<s...
