I would like to pay particular attention to the issue of cod.

I’m one of the Americans who didn’t know about black cod.

How many cod did they have left at the end of the day?

The cod trade was the key industry in the early part of the 19th century.

Cod, he thought, how many other people are at risk here?

It was not a cod because they had run away.

Cod fish are of course not found in fresh water.

She said: “I had my photograph taken with a dead cod.

The cod was thought to be healthy just four years ago.

This is the standard by which you will judge all other cod.

Did you see the rest of the cod I was eating?

Increasingly, the question being asked was, Where have the cod gone?

"We're not going to be teaching anyone how to break down a cod."

The other stocks will not go the same way as the cod'?

The situation with cod fishing will then turn out well, too.

The value of these three cod stocks is about $23 million.

Cod can be recognized by their large head and long body.

Cod have been called 'the fish that changed the world'.

Put the cod in a large bowl and cover it with cold water.

Go to the place where the salt cod is sold.

Thank Cod he was breaking through on the stories now.

The two most common fish used are salmon and cod.

Always had the same order - cod and two chips.

Thank Cod he was breaking through on the stories now.

The story of what happened to the cod fishery is often told.

I had that black cod again and it was a big improvement.

This does not just apply to cod and white fish.

The stocks of cod, for example, are even lower than they were in 1984.

Others, such as Atlantic cod, school only some of the time.

But the most interesting dish is made with local cod.

"Did you see the rest of the cod I was eating?"

The two most common fish used are salmon and cod.

Put the cod in a large bowl and cover it with cold water.

It is said that there are more than 365 ways to cook cod, one for every day of the year.

They even figured out how to keep cod from eating one another.

It's a tough place, especially since the cod disappeared a few years ago.

The area is also a local fishing spot, especially for blue cod.

When it comes to fish, the roast cod led the school.

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.

Chemical and biological oxygen demand, the combination of biochemical (BOD) and chemical oxygen demand (COD)
