Ways to control water pollution

Background[ edit ] Irrigation water is pumped from this tank which stores effluent received from a constructed wetland in Haran-Al-Awamied, Syria. Achieving more sustainable sanitation and wastewater management will require emphasis on actions linked to resource management, such as wastewater reuse or excreta reuse that will keep valuable resources available for productive uses. Simply stated, reclaimed water is water that is used more than one time before it passes back into the natural water cycle.

Ways to control water pollution

Pollution control Photo by: It is regulated by various environmental agencies that establish limits for the discharge of pollutants into the air, water, and land.

A wide variety of devices and systems have been developed to control air and water pollution and solid wastes. Air pollution control Methods of air pollution control can be divided into two categories: The term particulate refers to tiny particles of matter such as smoke, soot, and dust that are released during industrial, agricultural, or other activities.

Gaseous emissions are industrial products such as sulfur dioxide, carbon monoxide, and oxides of nitrogen also released during various manufacturing operations. Methods for particulate control tend to operate on a common principle.

The solid particles are separated from the gases in which they are contained by physical procedures such as passage through a settling chamber. A settling chamber is a long, wide pipe through which gases from a manufacturing process are allowed to flow.

As these gases slow down in the pipe, the solid particles settle out. They can then be removed from the bottom of the pipe. A cyclone collector is another device for removing particulates from stack gases. The gases are fed into a rotating cylindrical container.

Equipment for the complete recovery and control of acid and oxide emissions. Reproduced by permission of Phototake. Centrifugal forces the forces that move things away from the center of rotation send solid particles in the gas outward against the walls of the container.

They collect there briefly, then fall to the bottom of the container.

Gases from which the particles have been removed then escape from the top of the container. Many different methods are available for removing unwanted gases, most of which are acidic. Scrubbers are smokestack devices that contain a moist chemical such as lime, magnesium oxide, or sodium hydroxide.

When gases escape from a factory and pass through a scrubber, they react with the moist chemical and are neutralized.

From time to time, the scrubbers are removed from the smokestack, cleaned, and replaced. Another method for controlling gaseous emissions is by adsorption.

Activated charcoal is charcoal that has been ground into a very fine powder. In this form, charcoal has the ability to adsorb, or adhere to, other chemicals.

When unwanted gases flow over activated charcoal on the inside of a smokestack, they are adsorbed on the charcoal.

Air pollution control

As with scrubbers, the charcoal is removed from time to time, and a new lining of charcoal is installed in the smokestack. Water pollution Methods of controlling water pollution fall into three general categories: For example, one form of water pollution consists of suspended solids such as fine dirt and dead organisms.CHAPTER I PRELIMINARY 1.

Short title, extent and commencement. (1) This Act may be called the Air (Prevention and Control of Pollution) Act, (2) It extends to the whole of India. Reclaimed or recycled water (also called wastewater reuse or water reclamation) is the process of converting wastewater into water that can be reused for other purposes.

Division of Environmental and Financial Assistance

Reuse may include irrigation of gardens and agricultural fields or replenishing surface water and groundwater (i.e., groundwater recharge).Reused water may also be directed toward fulfilling certain needs in residences (e.g.

Pollution control is the process of reducing or eliminating the release of pollutants (contaminants, usually human-made) into the environment. Simply by going about your daily routines—using cleaning products, walking the dog—you might be unknowingly contributing to the pollution of our already struggling waterways.
