Wastewater Treatment Services in Andhra Pradesh

1. Let’s look at what is a water treatment plant : • Any machine or equipment that undertakes all or some of the above processes to provide usable water can be called as a water treatment plant. • The water being treated can be in any of the following forms: • Sewage water • Waste water • Industrial wastewater What is Water Treatment Plant?

2. Why is it necessary to treat water &Why we required water treatment plant in the Country, Cities, States & Home? • Top 5 countries with the large numbers of people living without access of safe water. • India-7,57,77,997 people • china-6,31,66,533 people • Nigeria-5,77,57,141 people • Ethiopia-4,22,51,031 people • Congo-3,39,06,771 people Water is a limited resource, so we must see how to reuse it to the max. Treatment of water at house, building, city and state level is the need of the hour. Here are some of the key steps to treat water to make it reusable. This is the need of the hour – especially in developing countries where life of entire cities and villages are reliant on getting the right amount and type of water to use. Let’s all decide to minimize the use of water and vow to recycle it in water plant machines, or water treatment plant for industrial as well as regular waste water.

3. Andhra Pradesh (AP), a state in southern India has been one of the leaders in industrial water treatment. The water treatment process in Vishakhapatnam one of the major cities in AP is one of the best in class treating industrial waste water as well as waste water. As this city recognized the importance and necessity of a water treatment system, the other states are also taking steps in this area.

4. The question arises; can we not just create more water as per our need? If only it were that simple. Is water created newly every time there is a chemical reaction or is it just recycled in the water cycle? There are debates going on about whether the water we have today is older than the dinosaurs... but that’s a different topic for a different blog. So, what is that the states and cities need to do? Well for starters, let’s understand if we can reuse water by treating it in some way.

5. Anywhere in the world you go, the water treatment process will primarily have the following steps:- • Coagulation It is the process of adding a coagulant to the water to destabilize the suspended particles. It is a chemical process in which the charge of the particles in water is neutralized. • Flocculation It is on the other hand a physical process in which certain polymers are added to the water so that the suspended particles come together to form a larger lump that can be easily removed through a process of separation like sieving or filtration. • Sedimentation In this process the water flows through sedimentation basins very slowly and the large floc particles settle down at the bottom due to its weight. The collected floc is called as sludge.

6. Filtration • The water further flows through a filter designed to remove suspended water impurities. The filters are made of sand, gravel and in some cases anthracite. It is an important process and further enhances the next process of disinfection. • Disinfection • Using chlorine, the water is disinfected to remove disease causing bacteria, viruses and parasites after which the water is fed into the distribution system. Depending on the hardness of the water another pH value adjustment may take place to ensure the distribution system does not corrode or rust with time. • Following these processes, the Vishakhapatnam water treatment plant has successfully reused water to a large extent.
