This comprehensive reference covers all aspects of water and wastewater analysis techniques.

Analysis of the literature and experimental results indicated that biological solids retention time is far more significant in determining increase in effluent chemical oxygen demand during periods of shock loading and that deterioration in sludge settling properties and a greater likelihood of converting the biomass to filamentous growth occur for shock loads at low values of solids retention time. ), Membership, Water Pollution Control Federation and New Jersey Water Pollution Control Association, Standard methods for the examination of water and wastewater, (
