Water is the most important & necessity element in human life. Approximately 70% of the human body, water is found in the cells. The source of all body fluids including blood, saliva, digestive enzymes, urines etc.is the pure drinking water. Water is the regulator of all body Functions. The brain is also made up of 80% of water, severe dehydration may lead to mental derangement, inability to think clearly. Thus human body requires a 6-8 glass of pure water daily to function properly.

An effluent treatment plant (ETP) is a wastewater treatment process (WWTP) that treats wastewater. It’s mostly used in industries like pharmaceuticals, textiles, and chemicals where there’s a risk of extreme water contamination. Effluent Treatment Plants areimportant in the treatment of both industrial wastewater and domestic sewage. Organic matter, inorganic matter, heavy metals, oil and grease, suspended particles, and other contaminants are all treated in an ETP plant’s wastewater treatment process. Wastewater treatment plants are classified into chemical treatment, biological treatment, a combination of chemical and biological treatment, and thermal treatment.
The treatment’s conceptual approach includes the removal of suspended particles,
dissolved organic matter, and the handling of sludge for disposal. The following
processes are involved:
The purpose of the equalization tank is to balance the raw effluent from various processing units. The wastewater is collected in an existing mixed effluent tank before being pumped to an existing aeration tank that also serves as an equalization tank. The floating aerator homogenizes the effluent before pumping it to the neutralization tank for treatment.
The P H of effluent should be between 5.5 and 9.0. (BIS). P H neutralization is a technique for modifying the P H of the wastewater. Acidic waste (low P H ): Bases are used to change the P H of a solution. Acids are used to modify the P H of a solution in the case of alkali waste (high P H ).
Coagulation is a technique that involves mixing untreated water with liquid aluminum sulfate. After mixing, the tiny dirt particles stick together. This collection of particles combines to form larger, heavier particles that can be easily removed via settling and filtration.
Filtration is the process of removing particulates from water by passing them through a filter. The filters are made of layers of sand and gravel. Backwashing is required regularly to clean these filters.
Because water moves slowly in this process, the heavy particles settle at the bottom. The particles that collect at the bottom of a container are referred to as sludge.
Water is disinfected before it enters the distribution system. Water is disinfected and decontaminated using chlorine.
Sedimentation collects and settles solids before transporting them to drying beds. When the sludge thickness reaches around 300 mm, the charging should be stopped and the bed separated to allow natural evaporation to dry it off. This process takes about ten days.

Effluent treatment plants work in several stages to remove all sorts of impurities from industrial wastewater. They can screen out solid waste and dust, disinfect the water, and purify it on a molecular level. This treated water is safe to be released into water bodies without disrupting the ecological balance. In the primary stage of an effluent
treatment plant, mostly solid and visible waste is removed. Dust and debris are also removed in the first stage. Screenings are done to separate solid waste from the effluent. Coagulants are used to have the contaminants clump together and sink to the bottom of the tank. From there, they can be separated easily. Wastewater is also put in a tank where the growth of bacteria is abundant. The contaminants get broken down by bacteria in that stage. The secondary stage of an effluent treatment plant finely cleanses the water. Activated
carbons are used in this stage to capture chemicals and heavy metals. Chlorine and ultraviolet rays are frequently used to disinfect the wastewater. Many industry owners prefer to use ultraviolet rays to reduce the use of chlorine. If chlorine is used, the wastewater should be pushed through carbon filters to pull out excess amounts from the water. After the secondary stage, the water is safe enough to be released into the environment. Reverse osmosis filters might be used to get rid of any molecules that are larger than a water molecule and turn the water into its purest form. The machinery used in effluent treatment plants should be kept clean and well maintained to have the best performance. Good quality chemicals should be used to
have the water purified thoroughly.
You should get a wastewater treatment plant to turn harmful and toxic wastewater into safe water. With the industrial revolution, humans are producing more and more wastewater every year.
The bacteria present in the water bodies are incapable of breaking down such a large amount of waste. As a result, rivers, canals, and lakes are dying.
With the waste clogging the water bodies, freshwater plants and fishes are dying. The supply of fish has significantly dropped due to water pollution.
Excessive chemical and toxic elements in the water change the color, taste, and smell of the water. As a result, the water quality decreases, and water-borne diseases and heavy metal poisoning are breaking out.
The excessive amount of water pollution is creating a scarcity of water.
To maintain the environmental balance and to keep safe water available for everyone we should use wastewater treatment plants. These plants will separate the waste and make the water safe to be used again.
Releasing this water into the environment will not disrupt the balance. Treating the wastewater will make the water regain its natural taste, color, and smell. This water will be safe to drink again.
If you are considering installing a wastewater treatment plant, you might have heard about STPs and ETPs. But what are the differences between STP and ETP? How can you decide on which one to install?
Even if you could settle on one, how should you make sure that the plant will be cost-effective and provide the best service? These questions may have you confused if you are to install a wastewater treatment plant.
You should get STP if you want a plant in your municipality to treat sewage. These plants will cost a little less since they mostly deal with organic waste that can be easily treated.
If you are an industry owner, you would need to install an effluent treatment plant. They are sophistically made to treat the chemicals and toxic waste in several stages to turn the wastewater into safe water.
This water can be released into water bodies without threatening the environment.
The plant you are installing should be carefully planned. For that reason, you should call in an expert and have the wastewater tested.
They will list down the kinds of contaminants present in the wastewater and design a plant that is capable of eliminating all of them.
They will also consider the amount of wastewater the plant will have to deal with and construct it in a way that will be powerful to deal with all the waste materials.
The plant you are building should at least be capable of dealing with all the waste that your factory or municipality produces. You should not be miserly about it and invest in quality machinery and chemicals.
If you try to get it made cheaply, the machinery may break down often and need maintenance.
On top of that, the plant will not be capable of cleaning the wastewater thoroughly. You should try your best to have the best water treatment plant built.
Green Dot Limited has experts who can help you understand everything about sewage treatment plants and effluent treatment plants. They both have to be planned out thoroughly to make sure the wastewater is treated properly.
It is imperative to use good machinery and quality chemicals in these plants. Getting your plant installed by a reputed company will guarantee that the device is capable of providing the best service.

Sewage treatment plants work by separating waste from the sewage and turning it into safe water. This water is purified to a level that is safe to release into the environment. Sewage treatment plants break down the organic waste present in the sewage and turn it into clean water. These plants are built to deal with a large amount of sewage in municipalities.
In the first stage of cleaning in a sewage treatment plant, the sewage is kept in a tank for an extended period. At this time, the solids present in the sewage sink to the bottom of the tank. Grease, excreta, etc. travel to the top and settle there. From this stage, the liquid wastewater gets separated and moves on to the next stage to be cleaned further.
In the second stage, sewage treatment plants put the water in a tank and allow ample airflow. This airflow encourages the growth of bacteria that is capable of quickly breaking down the waste in the water.
In this stage, most of the waste in the water is separated by the bacteria and the water is nearly safe enough to release into the environment.
In the last stage of a sewage treatment plant, the wastewater is screened, so the remaining solid in the wastewater can be separated. After this stage, the water is safe to be released into water bodies.
If all the stages work perfectly, this treated sewage will not burden the environment and clog our water bodies.
Have you ever wondered, what are the differences between STP and ETP? The first difference is that STP deals with sewage and ETP deals with effluent. Sewage is produced in households, and they contain waste materials like human and animal feces and food waste. Effluent is produced in factories, and they contain a large amount of chemical and toxic waste. Sewage treatment plants have less complex mechanisms since they mostly deal with organic waste. It breaks down the waste with the help of aerobic bacteria and screens out solid waste. Effluent treatment plants have complex mechanisms because they deal with chemicals and toxic waste. If they aren’t treated well, they will harm the environment immensely.
Sewage treatment plants are used by municipalities. They deal with the wastewater that gets produced in residential areas. The treated water gets released into the sewage system again.
It does not create clogging or unpleasant smell this way. Effluent treatment plants are used in industries. In the factories, a large amount of wastewater is produced that is crawling with chemical and toxic waste.
The plants get rid of this waste and make the water safe enough to be released into water bodies. Both STP and ETP plants have to be constructed with proper planning to make sure they can deal with the wastewater perfectly. Building an ETP would be costlier than building an STP since it is a more elaborate model. However, you should get an ETP to treat the effluent produced in your industry. You must not consciously harm the environment because it will be harmful to you too.
