biochemical oxygen demand , BOD (Abkürzung)
oxygen demand

Biochemical oxygen demand of the water in 2004 was 0.1 mg/L, which means good condition.

Current biomonitering techniques focus mainly on community structure or biochemical oxygen demand.

That area of the river also exhibited the highest biochemical oxygen demand, indicating high biodegradable organic matter content.

Plants along the banks, damaged by the drought, dropped organic debris into the water, increasing biochemical oxygen demand substantially.

Fecal coliform bacteria, total solids, and biochemical oxygen demand also impaired water quality.

The plant is expected to begin secondary treatment next year, which means removal of 85 percent of both biochemical oxygen demand and suspended solids.

The plan called for major cleanup of the lower river in order to protect salmon from phosphorus, nitrogen, and carbonaceous biochemical oxygen demand.

As a result, the final effluent was a deep red colour, and were a major factor in the poor biochemical oxygen demand ratings for the river.

The strength of wastewater is commonly evaluated as biochemical oxygen demand (BOD) values.

Biochemical oxygen demand is the amount of oxygen required for microbial metabolism of organic compounds in water.

A 2009 survey shows that the chemical oxygen demand and biochemical oxygen demand in the water body increased drastically after these festivals.

Such water quality parameters as biochemical oxygen demand, nitrites, copper, phenols exceeded the maximum allowable concentrations.

Discharges from them significantly increased the ammonia content and the biochemical oxygen demand (BOD) of the river.

These measures lead to a steady decrease in the biochemical oxygen demand in the river, and in the Rother.

Those biochemical reactions create what is measured in the laboratory as the biochemical oxygen demand (BOD).

Biochemical oxygen demand (BOD)

In simple terms, the more the biomass consumes the lower the biochemical oxygen demand (BOD) will be in the discharge.

Secure swimmable water quality (level two, Biochemical Oxygen Demand 3ppm) by 2012, earlier than the originally scheduled 2015.

Without refrigeration, milk is a fragile commodity, and it is very damaging to the environment in its raw state due to its high biochemical oxygen demand.

Propylene glycol is known to exert high levels of biochemical oxygen demand (BOD) during degradation in surface waters.

Metcalf & Eddy quantified this impact as 0.04 pounds of biochemical oxygen demand per person per day where disposers are used.

The Streeter-Phelps equation was the first quantitative model that was used to determine the impact of biochemical oxygen demand discharges to surface water bodies.

The actual oxygen demand can be measured experimentally and is called the biochemical oxygen demand (BOD).

Was biochemical oxygen demand (the amount of oxygen in the water needed for the aerobic decomposition of sewage plant effluent) no greater than 8 mg/litre?

Biochemical Oxygen Demand (BOD)

However, large numbers of bacteria are found within the sediment which have a very high oxygen demand.

This is accomplished by measuring the biological oxygen demand of the water.

The amount of air sucked in depends on the customer's oxygen demand.

They can use the environmental systems to find out where lights are being used, where the oxygen demand is up.

We'll turn our thermostats down and sit very quiet to reduce oxygen demand.

Biochemical oxygen demand of the water in 2004 was 0.1 mg/L, which means good condition.

Angina results when there is an imbalance between the heart's oxygen demand and supply.

Internal temperature, oxygen demand, humidity controls were all computer controlled.

The decrease of stress also decreases oxygen demand of the heart.

This high "biological oxygen demand" can suffocate fish and other organisms.

The theoretical oxygen demand represents the worse case scenario.

Oxygen demand is an environmental chemistry term that may refer to:

The laboratory test procedures for the determining the above oxygen demands are detailed in many standard texts.

Keeping her mouth open, quick pants barely kept up with her body's oxygen demands.

At a cellular level shock is oxygen demand greater than oxygen supply.

This infestation creates a large oxygen demand in the Lake, limiting cold water habitat.

I could sense my oxygen demand rising, both physically and through the selfnet.

However, increasing interest has been shown in trading programs for sediment runoff, biological oxygen demand, and temperature.

This practice usually results in increased effluent toxicity and oxygen demand on the receiving waters.

Citric acid or citrate both add to the chemical oxygen demand level of the water.

Due to their high metabolic rate required for flight, birds have a high oxygen demand.

Biological oxygen demand has also been reduced.

This expression does not include the oxygen demand caused by the oxidation of ammonia into nitrate.

In general organic nitrates decrease oxygen demand and increase oxygen supply.

They also decrease cardiac oxygen demand and can prevent cardiac remodeling.
