Chemical Oxygen Demand , COD effluent (Abkürzung)

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

Foam separation has also been found to be able to decrease the chemical oxygen demand when used as secondary treatment technique for wastewater.

They also have a large chemical oxygen demand (COD).

Many governments impose strict regulations regarding the maximum chemical oxygen demand allowed in wastewater before they can be returned to the environment.

Thorough washing of the pulp reduces the chemical oxygen demand (COD).

The reduction of Chemical Oxygen Demand, a measure of organic water pollution, was increased from 30% to 80%.

However, in the same year chemical oxygen demand was above the allowed limit of 10 mg/liter in 7 of 11 governorates.

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

Water chemical oxygen demand (Food and Agriculture Organization of the United Nations)

Those chemical reactions create what is measured in the laboratory as the chemical oxygen demand (COD).

Dichromate does not oxidize ammonia into nitrate, so this nitrification can be safely ignored in the standard chemical oxygen demand test.

A potential hazard of significant discharges to watercourses is the rise in chemical oxygen demand (C.O.D.) associated with its biodegradation.

Chemical oxygen demand (COD)

In environmental chemistry, the chemical oxygen demand (COD) test is commonly used to indirectly measure the amount of organic compounds in water.

Simultaneous Chemical oxygen demand, and Nitrogen and Phosphorus removal, can be easily integrated in a discontinuous fed system.

It also depends on an assessment of parameters such acidity levels, temperature, odour, and biochemical oxygen demand and chemical oxygen demand.

For many years, the strong oxidizing agent potassium permanganate (KMnO) was used for measuring chemical oxygen demand.

This means that the chemical oxygen demand(COD) removed is relatively little and the effluent is therefore unacceptable for discharge into receiving waters.

Chemical Oxygen Demand (COD) A measure of the oxygen-consuming capacity of inorganic and organic matter present in wastewater.

Includes pollutants such as chemical oxygen demand (COD), total organic carbon (TOC), nitrogen, and phosphorus.

Red meat abattoirs use large volumes of water and generate equally large volumes of wastewater with a high chemical oxygen demand and suspended solids content.

Iron, manganese, formaldehyde, chemical oxygen demand and biochemical oxygen demand (BOD) also exceeded the maximum allowed limits.

In 2001 the distillery began using Biobed Modular Plant technology to treat wastewater with low chemical oxygen demand (COD) loads.

For example, you may need to monitor and stay within specified limits for the main components of your discharges, such as flow rate, pH, temperature, suspended solids, or chemical oxygen demand.
