Basically,
calorific value of any sludge depends on its constitution. Since sludge is not defined composition wise, its accurate calorific value doesn't exist.
And another important factor which affects the calorific value is the end product that's generated out of sludge. eg if biogas is generated, then calorific value would be 22,000 kJ/Nm3 (http://www.currenta.com/pages/1577/life_2008_final_engl.pdf)

How do engineers help the environment?
Engineers are vital to day-to-day environmental problems like dealing with waste and making sure the water supply is clean and reliable. They design waste treatment plants, as well as the necessary technology to monitor water quality.
What is a water engineer called?
Water engineer is a generic title given to engineers who specialise in water-based projects; many have a civil engineering or environmental background. They may work with a variety of different liquids but generally deal with the provision of clean water, disposal of waste water and sewage, and prevention of flood damage.
What are facts about environmental engineering?
A 12 science student can appear joint entrance examination to pursue environmental engineering. Environment is the recent buzz. Scopes and opportunities of an environment engineer can work in the domains ofRadiation protectionWaste water managementLand managementHazardous waste management etc.
When water leaves a body of water after it is heated the process is called?
The process by which water leaves a body of water after it is heated is called "evaporation." This occurs when the water molecules gain enough energy from the heat to break their bonds and transition from a liquid to a gaseous state. The resulting water vapor rises into the atmosphere, where it can eventually condense and form clouds, leading to precipitation and the cycle of water.
What is nano water?
Multiple products have been named "nano water". They are generally quack medical cures or water filters.
Why does the water gas has a high calorific value?
The water gas has a high calorific value because it produces immense heat during its combustion.
Why does water gas has a high calorific value?
The water gas has a high calorific value because it produces immense heat during its combustion.
What is the importance of the calorific value of a fuel?
The higher the calorific value of a fuel, the higher its combustion rate is, which is important knowledge to know. A low calorific value indicates more water vapor absorption.
What is NCV means in the coal industry?
NCV means Net Calorific Value. The lower calorific value or Net calorific value (NCV) which supposes that the products of combustion contain the water of combustion to the vapor state. The heat contained in this water is not recovered.
Why is net calorific value is less than gross calorific value?
The lower calorific value or Net calorific value (NCV) which supposes that the products of combustion contain the water of combustion to the vapor state. The heat contained in this water is not recovered.The higher calorific value or Gross calorific value (GCV) which supposes that the water of combustion is entirely condensed. The heat contained in this water is recovered.sayed karar waris
The pressence of Pin floc and a rapidly setting sludge are indicators of what in waste water?
The organism such as protozoan and rotifers.
What is the calorific value of tap water?
Technically, the caloric value of water should be zero. However, contaminants and minerals may add up to 10 calories to a glass of water.
What is the startup procedure of treatment with activated sludge?
This is a big open ended question. Is this for a waste water plant? I would start with a Google search for the water, waste water association for your state. If you have a more specific question, maybe I can help.
How many kg of fuel to evaporate 1 kg water?
The answer will depend, among other things, on the calorific value of the fuel.
What is the effect of volatile substances and water on calorific value of coal?
Volatile elements (hydrocarbons) increase the value, moisture takes up space, absorbs heat and lowers the value.
Where does cruise ship pollution go?
Waste water from toilets goes to a waste water treatment plant. So called gray water from showers and bathroom sinks goes straight overboard. Food waste and packing materials gets burned in an incinerator. Other incombustible materials gets compressed and send to a plant ashore. Oil and sludge in the engine room normally get separated from the water and the sludge gets burned in the incinerator and the clean water gets pumped overboard.
How do you convert ncv to gcv?
The calorific value is the measurement of heat or energy produced, and is measured either as gross calorific value or net calorific value. The difference being the latent heat of condensation of the water vapour produced during the combustion process. Gross calorific value (GCV) assumes all vapour produced during the combustion process is fully condensed. Net calorific value (NCV) assumes the water leaves with the combustion products without fully being condensed.
