INTRODUCTION :

Air pollution is the introduction of chemicals, particulate matter, or biological materials that cause harm or discomfort to humans or other living organisms, or cause damage to the natural environment or built environment, into the atmosphere. Air Pollution Control System Manufacturers - The atmosphere is a complex dynamic natural gaseous system that is essential to support life on planet Earth. Stratospheric ozone depletion due to air pollution has longbeen recognized as a threat to human health as well as to the Earth's ecosystems.

WET SCRUBBER :

The design of wet scrubbers or any air pollution control device depends on the industrial process conditions and the nature of the air pollutants involved. Wet scrubbers remove dust particles by capturing them in liquid droplets. Wet scrubbers remove pollutant gases by dissolving or absorbing them into the liquid.

ESP (Electrostatic Precipitator) :

An Electrostatic Precipitator (ESP) is a device which removes particles from a gas stream. It accomplishes particle separation by use of an electric field. The fundamental principle is that the particulates are passed through an electric field where they initially receive an electric charge and then as a charged particle are deflected across the field to be collected on an earthed plate. Then the particles on the collection surface are removed to a hopper by rapping the collection surface.

INTRODUCTION

Water is the most essential element of our lives. Water from different sources can be found to have different characters. Because water becomes contaminated by the substances with which it comes into contact, it is not available for use in its pure state. To some degree, water can dissolve every naturally occurring substance on the earth. Because of this property, water has been termed a “universal solvent.”

INTRODUCTION

The wastewater generation and its treatment has become a consequential health issue in the developing countries due to the inadequate treatment facilities. The discharge of untreated wastewater in surface and sub-surface water courses is the most important source of contamination of water resources.

Depending on the Source the type of effluent generated is categorized into two type :-

1. ETP – Effluent Treatment Plant

2. STP – Sewage Treatment Plant

METHODS OF TREATMENT

While ETP is entirely Chemical based treatment system depending on the contents of the chemical present in the discharged effluent whereas STP is both Anaerobic as well as Aerobic. The combination of both systems has also been used in STP’s.

ADVANTAGES OF GREEN TECHNOLOGY

• This treatment is low energy dependent and has distinct advantage over all the conventional wastewater treatment systems- the Activated Sludge Process, Trickling Filters, and Rotating Biological Contactors which are highly energy intensive, costly to install and operate, and do not generate any income.
• In the Bio – Culture there is 100% capture of organic materials, the capital and operating costs are less, and there is high value added end product
• Sludge is useful soil additive for agriculture and horticulture
• There is no foul odor as these Set of Microbes and Enzymes arrest rotting and decay of all putrescible matters in the wastewater and the sludge.

BRIEF

Every Year we Humans had been wasting the Most Precious and important thing which is the lifeline for every living Organism on Earth i;e WATER. Be it anywhere this precious lifeline has been ill – treated with and had not been taken with serious note. Now when the scarcity has been on rise everywhere, the ways and methods are being applied for efficient use. While other part of Increasing the Underground Water Level ie AQUIFER. The best and most adopted process is Rain Water Harvesting.

Rain Water harvesting depends on Amount of Rainfall and whether the Rain Water to be harnessed is of Roof Top or Pavement Area. It is good to harness Rain Water of Roof Top as it is of Good Quality rather than any other surface. The one that we are promoting is Rain Water Harvesting which is Modular Type.

DEFINE

Activated Carbon Filter is used to adsorb chlorine, organics , taste, odour, and colour from Water & Wastewater.

OPERATING PRINCIPLE

Activated carbon filtration is an adsorptive process in which the contaminant is attracted to and adsorbed onto the surface of the carbon particles. The efficiency of the adsorption process is influenced by carbon characteristics (particle and pore size, surface area, density and hardness) and the contaminant characteristics.

DEFINE

Multi Grade Filter is used for removal of suspended solids, turbidity and some part of colour and odour from Water & Wastewater

OPERATING PRINCIPLE

Raw water is passed through the Multi grade media filter, contains anthracite at a top layer of media followed by fine & Coarse Garnet and quartz sand supported by pebbles and gravels. Multi grades of media and layers provide extra ordinary dirt holding capacity at various level of total media depth and produce unparalleled filter water quality. During the filtration cycle the largest particles are strained out by the anthracite, coarse and fine sand, Coarse & fine garnet though a combination of adhesion and straining. Since the particles in the water are filtered out at various depths in a multimedia filter, the filter does not clog as quickly as if all of the particles were all caught by the top layer.

A wet scrubber is a type of filter that removes pollutants from a gas stream by using a liquid to wash them out. The liquid is usually water, but other chemicals can be added to react with specific contaminants. The working principle of a wet scrubber depends on how much energy is used to bring the gas stream into contact with the liquid. In wet scrubbing processes, liquid or solid particles are removed from a gasstream by transferring them to a liquid. The liquid most commonly used is water. A wet scrubber's particulate collection efficiency is directly related to the amount of energy expended in contacting the gas stream with the scrubber liquid

The solvent’s composition affects its ability to absorb contaminants. The critical factor is the solvent’s electric charge. A positive, negative or neutral charge will allow the solvent to bind with different inorganic pollutants. Some of the most common wet scrubber solvents include:

Water, or H2O.

Sodium hydroxide, or NaOH.

Calcium hydroxide, or Ca(OH)2.

Sodium carbonate, or Na2CO3.

As the solvent absorbs contaminants, a new solvent is necessary to purge the pollutants and replace the evaporated liquid. Solvent flooding can be either continuous or periodic. A wet scrubber’s effectiveness depends on how much gas makes contact with the solvent, which requires a stream of energy. Low-energy scrubbers can remove large particles, while high-energy scrubbers can remove the tiniest particles.

All wet scrubbers, whether high or low energy, have a mist eliminator component. The mist eliminator collects and removes the contaminated droplets from the solvent. An effective mist eliminator is a fundamental component of any wet scrubber. Before discharging or reusing scrubbing liquid, it’s essential to treat it to ensure total pollutant removal. A wet scrubber can control specific airborne pollutants. Industries that produce such pollutants should consider using wet scrubbers to minimize environmental impact and human safety risks. They can help reduce any of the following air pollutants.

1. Inorganic Fumes, Vapors and Gases > Some of the most common such pollutants include:

Chromic acid. Hydrogen sulfide. Ammonia. Chlorides. Fluorides. Sulfur dioxide.

2. Volatile Organic Compounds > A wet scrubber can also remove VOCs produced during specific manufacturing

Paints. Paint strippers. Industrial cleaning supplies. Fuels.

Varnishes Building materials. Pest control solutions. Adhesives.

3. Particulate Matter > Other air pollutants include PMs of the following, given a size of 10 mm or smaller

Dust. Dirt. Soot. Smoke. Pollen.

4. Hazardous Air Pollutants > Toxic air pollutants, have grave health implications. They may cause cancer, birth
