Reduction of Chemical Oxygen Demand (COD) in wastewater by electrocoagulation using aluminum-aluminum, iron-iron, aluminum-iron electrode pair systems and three pair multi electrode system (iron-aluminum-titanium/iron-iron-iron).Electrocoagulation (EC) has been performed with Al-Al, Fe-Fe, Al-Fe ...
Biological oxygen demand is defined as the reduction of waste water and 1L of oxygen required for reagent quality 翻译结果2复制译文编辑译文朗读译文返回顶部 And 1L is the definition of biological oxygen demand in wastewater by reduction reagents of the oxygen required quality ...
Therefore in order to control the quality of the water a few parameters have been chosen as the index for determining the water pollution. Amongst the parameters, Biochemical Oxygen Demand, (BOD) is one of the most important and frequently used parameters for estimating the level of water ...
The potential of fly ash, brick kiln ash and commercial activated carbon is determined for the reduction of chemical oxygen demand (COD) from domestic wastewater. Laboratory experiments are conducted for investigating the effect of treatment time, adsorbent dose, pH of the media, initial COD concent...
EFFICIENCY OF SELECTED STRAINS OF FUNGI IN REDUCING CHEMICAL OXYGEN DEMAND IN WASTEWATER FROM STEAM‐PEELED POTATOES1 The use of certain selected strains of fungi to reduce the wastewater strength from steam-peeled potato effluent and the recovery of the biomass produced by the fungal mycelium was ...
bi′ochem′ical ox′ygen demand` n. the oxygen required by aerobic organisms, as those in sewage, for metabolism. Also calledbiological oxygen demand. [1925–30] Random House Kernerman Webster's College Dictionary, © 2010 K Dictionaries Ltd. Copyright 2005, 1997, 1991 by Random House, Inc...
The influent then passes a dense and anaerobic granular biomass bed where the biological treatment takes place converting the COD load (Chemical Oxygen Demand) present in the wastewater into biogas. 进水通过一个稠密的厌氧颗粒污泥床进行生物处理,将废水中的COD(化学需氧量)负荷转化为沼气。 ParaCrawl...
A number of alternative tests are available to indicate the “oxygen demand” of a wastewater, including total organic carbon (TOC) and permanganate value (HMSO, 1972; American Public Health Association, 1992). Typical BOD:TOC ratios for untreated effluent are in the range 1.2:1–2.0:1. View...
The measurement of oxygen uptake rate is quick,simple and sensitive,so in many overseas wastewater treatment plants,its application has been spreaded.This paper based on the measurement of oxygen uptake rate,makes the bio-chemical breath curves and relative oxygen uptake rate curves.Also this paper...
