General process for Sewage Tretment

1. Screening

Wastewater entering the treatment plant includes items like wood, rocks, and even dead animals. Unless they are removed, they could cause problems later in the treatment process. Most of these materials are sent to a landfill.

2. Pumping

The wastewater system relies on the force of gravity to move sewage from your home to the treatment plant. So wastewater-treatment plants are located on low ground, often near a river into which treated water can be released. If the plant is built above the ground level, the wastewater has to be pumped up to the aeration tanks (item 3). From here on, gravity takes over to move the wastewater through the treatment process.

3. Aerating

One of the first steps that a water treatment facility can do is to just shake up the sewage and expose it to air. This causes some of the dissolved gases (such as hydrogen sulfide, which smells like rotten eggs) that taste and smell bad to be released from the water. Wastewater enters a series of long, parallel concrete tanks. Each tank is divided into two sections. In the first section, air is pumped through the water.

As organic matter decays, it uses up oxygen. Aeration replenishes the oxygen. Bubbling oxygen through the water also keeps the organic material suspended while it forces ‘grit’ (coffee grounds, sand and other small, dense particles) to settle out. Grit is pumped out of the tanks and taken to landfills.

4. Removing sludge

Wastewater then enters the second section or sedimentation tanks. Here, the sludge (the organic portion of the sewage) settles out of the wastewater and is pumped out of the tanks. Some of the water is removed in a step called thickening and then the sludge is processed in large tanks called digesters.

5. Removing scum

As sludge is settling to the bottom of the sedimentation tanks, lighter materials are floating to the surface. This ‘scum’ includes grease, oils, plastics, and soap. Slow-moving rakes skim the scum off the surface of the wastewater. Scum is thickened and pumped to the digesters along with the sludge.

Many cities also use filtration in sewage treatment. After the solids are removed, the liquid sewage is filtered through a substance, usually sand, by the action of gravity. This method gets rid of almost all bacteria, reduces turbidity and color, removes odors, reduces the amount of iron, and removes most other solid particles that remained in the water. Water is sometimes filtered through carbon particles, which removes organic particles. This method is used in some homes, too.

6. Killing bacteria

Finally, the wastewater flows into a ‘chlorine contact’ tank, where the chemical chlorine is added to kill bacteria, which could pose a health risk, just as is done in swimming pools. The chlorine is mostly eliminated as the bacteria are destroyed, but sometimes it must be neutralized by adding other chemicals. This protects fish and other marine organisms, which can be harmed by the smallest amounts of chlorine.

Water is undoubtedly the most essential natural asset. This is the most important basic necessity of life. Water is used for different purposes. However, it is inevitably used for the purpose of drinking. Apart from household utilization, water is also used indispensably for industrial purposes. Though it is found in the nature in abundance, a major part of it is contaminated. And thus water should be treated properly to make it reusable. Here the need for introducing effluent treatment plants manufactured by reputable packaged ETP manufacturer comes into play.

What is the effluent treatment plant or ETP?

Effluent treatment plant cleans industrial effluents, contaminated water from rivers and lakes, and so on just in order to reuse the water for additional purposes. Along such lines, water is reutilized and sustained. In fact, such gushing treatment ensures that any contaminant will be expelled from the water making it reusable. It is mostly used in industries such as pharmaceuticals, textiles, tanneries, and chemicals where there is a chance of extreme water contamination. Nevertheless, how this treatment will be applied may vary from industry to industry.

Such treatment plant ensures that the contaminated and polluted water from industries get treated and become reusable before being released back to nature. Without this treatment, it won’t be possible for humans to get clean usable water for household chores.

 

What are the benefits of ETP?

ETP plays an important role in treating industrial wastewater as well as sewages generated from households. Packaged effluent treatment plants help both small- and medium-sized industries by disposing of the effluents generated at their facilities. Otherwise, it would be difficult for them to properly treat wastewater. They might also need to have extra space for contaminated water treatment. However, they may need to treat the water for the purpose of solid evacuation to ensure that the sewer can flow freely. Also, expulsion of some toxins is necessary prior to release the wastewater in ETPs.

• Results in clean reusable water — ETPs manufactured by any leading packaged ETP manufacturer ensure safe and clean water. Before the inception of this amazing treatment plant, people were hardly aware that polluted and impure water can be reused. The treatment method followed by ETPs includes the elimination of toxin from the water in order to generate safe and clean water.
• Saves you money — It also ensures complying with industry standards and regulations.
• Saves our planet — ETPs remove any unsafe chemical from water in order to treat it and make it ready for reuse. So when this treated water will enter the ground, it will leave no negative effect on the planet. ETPs are bliss for the industry owners.
• Saves water — By using an ETP, you can save water. The plant recycles old contaminated water ensuring less water wastage and that is certainly good for the earth. If you are concerned about the carbon footprint your business might leave, ETPs are the best way to serve Mother Nature in a better way.

ETP helps to purify wastewater generated from households as well as industry. The treatment process results in reusable clean water, saves your money as well as water and our planet.
