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.
What is the calorific value of water hyacinth?
The calorific value of water hyacinth is approximately 17-19 MJ/kg.
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.
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
How do you convert gross calorific value to net calorific value?
You can convert gross calorific value (GCV) to net calorific value (NCV) by subtracting the latent heat of vaporization of water formed during combustion from GCV. The equation for this is NCV = GCV - 2.5 x (9 x % H2 - % O2), where % H2 is the percentage of hydrogen in the fuel and % O2 is the percentage of oxygen in the fuel.
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.
What is the effect of volatile substances and water on calorific value of coal?
Volatile substances in coal tend to increase the calorific value as they can release more energy during combustion. On the other hand, high moisture content in coal reduces the calorific value by absorbing some of the heat energy during combustion to evaporate the water. Overall, the presence of volatile substances can have a greater impact on the calorific value compared to water content.
What is hypo sludge?
Hypo sludge, also known as paper mill sludge or paper-making waste, is a byproduct of the paper industry. It is a mixture of water, chemicals, and residual fibers left over from the paper-making process. Hypo sludge can be used in various applications such as construction materials or as a soil conditioner.
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.
The pressence of Pin floc and a rapidly setting sludge are indicators of what in waste water?
The organism such as protozoan and rotifers.
Why does the water gas has a high calorific value?
Water gas, also known as synthesis gas or syngas, has a high calorific value because it contains a mixture of hydrogen and carbon monoxide, two gases that have high energy content. When combusted, these gases release a lot of heat energy per unit volume, making water gas a valuable fuel source for various industrial processes.
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.
