Biomass: Making Eco-sustainable Energy Solutions Possible

Image
Biomass is a renewable source of energy, which is developed from organic matter that is otherwise dumped or burnt. Biomass is preferred over fossil fuels owing to its emission of reduced carbon as compared to fossil fuels, and is widely used to produce electricity, thermal energy, and other forms of power. The most significant benefit of biomass energy is its easy procurement, given its a renewable source . The other benefits of this renewable source of energy are as follows: 1)Carbon neutral The fuel produced using biomass doesn ’ t emit carbon. Biomass is made up of organic matter and contains guaranteed levels of carbon that have already been discharged, making it an eco-friendly energy source, which helps control climate change by reducing greenhouse gases produced during energy creation. With the new and advanced technologies that control pollution and combustion engineering the emissions from biomass in industrial facilities are significantly less compared t...

Why do we need sewage treatment plants?

Image
Environmental deterioration is an unfortunate remnant of rapid industrialisation and development of economies. Managing the levels of pollution has become imperative today. With the large population of our country and the industrial landscape expanding at such an explosive rate, the volume of wastewater is also increasing; sewage being a primary pollutant of water bodies. Sewage treatment involves the removal of contaminants from wastewater. Sewage is put through various chemical, physical, and biological treatments to produce an environmentally safe treated effluent. Sewage treatment is important; for without it, water is unfit for consumption and if mixed with other water sources including the underground water can contaminate them too. With the limited water resources we have today, wastewater management is no longer a choice but a necessity. Today we have sophisticated methods to treat wastewater. Here are some of the common methods used by sewage treatment plants in India : 1)...

What is a Zero Liquid Discharge System and How Does it Work?

A Zero Liquid Discharge System (ZLD) uses advance technology for treating water to reduce and eliminate the liquid waste produced at the end of an industrial process. A well-designed, high performing ZLD treatment system does the following: Handles variations in waste contamination and flow Allows for required chemical volumes adjustments Recovers approximate 95% of liquid waste for re-use Treats and retrieves valuable byproducts such as salt and brine from waste Produces a dry, solid cake for disposal A ZLD treatment system is one among the many available alternatives of water purification systems. It helps a facility meet its stringent effluent requirements. The components of a ZLD treatment system largely depend on the: 1. Volume of dissolved material present in the waste 2. Required flow rate of the system 3. Specific contaminants present in the waste Any basic ZLD treatment system typically consists of the following: Clarifier and reactor to precipitate met...

All you need to know before you buy an Air Scrubber

Image
Air scrubbers are used to remove harmful particles and gases from the air within a certain radius.  Scrubbers are mostly used in industries to prevent workers from being exposed to harmful substances. Air scrubbers are designed for specific kinds of air purification; some are for the elimination of particles, some for gases, and some for chemicals.  Typically air scrubbers use ions to purify the air. Scrubbers that don ’ t use ions consist of a fan and filter which periodically take in large amounts of air, and force out clean air from the other side. Air scrubbers use a technique called   wet scrubbing in which air is passed through a moist cloth or liquid chamber. Particles stick to the wet cloth as air passes through it, allowing only clean air to exit the scrubber. Plain water or specific chemical compounds are used to keep the scrubbers moist.  There are a few things one must pay close attention to before purchasing an air scrubber:  ...

How do Boilers Help Plants Run Smoothly?

Image
A boiler makes for one of the most fundamental systems in a refinery or plant. Ensuring the continuous and efficient functioning of a plant is important. This article explores how a boiler functions and how it impacts other aspects of a plant. A boiler is a closed vessel that converts water to steam.  Chemical energy from a fuel source is turned into heat by combustion making this possible. This heat is transferred to the contained water which increases pressure, and then converts the liquid form into steam. An indicator of a good boiler is design that ensures transfer of maximum heat from the combustion into water. This is done using processes such as radiation, conduction, and convection. The efficiency of heat transfer matters here so that the fuel being burned yields the maximum, most cost effective results. So why do plants actually need the steam produced by boilers? This varies depending on the plant, but largely the steam produced by boilers will serve one of the follo...
