collect the information about reverse osmosis and its use in daily life
Answers
Answer:
Reverse osmosis helps in removing many types of suspended and dissolved species from water. It helps in removing bacteria and removes the impurity of the water. In the process of reverse osmosis desalination, pressure is applied to overcome the osmotic pressure which is driven by all the chemical potential solvents.
The solute solution is passed through a semi-permeable membrane in which the solvent passes and leaves a high concentrated solute. For better understanding, you can think salty water as the solution, water as the solvent and salt as the solute.
Importance of Reverse Osmosis
1. It is an important resource to create a sustainable source of drinking water.
2. Reverse osmosis removes various undesirable substances from the water like iron, potassium, zinc and thus used in many large scale industries. By doing so, the pressure on local water sources gets reduced.
3. Countries having water shortage due to infrastructure or any financial problem can have fresh and pure water and can decrease all types of diseases which are caused due to the impure water.
The Satavahanas (Sādavāhana or Sātavāhana,[2] IAST: Sātavāhana), also referred to as the Andhras in the Puranas, were an ancient Indian dynasty based in the Deccan region. Most modern scholars believe that the Satavahana rule began in the late second century BCE and lasted until the early third century CE, although some assign the beginning of their rule to as early as the 3rd century BCE based on the Puranas, but uncorroborated by archaeological evidence.[3] The Satavahana kingdom mainly comprised the present-day Telangana, Andhra Pradesh and Maharashtra. At different times, their rule extended to parts of modern Gujarat, Madhya Pradesh, and Karnataka. The dynasty had different capital cities at different times, including Pratishthana (Paithan) and Amaravati (Dharanikota).The Satavahanas participated in (and benefited from) economic expansion through intensification of agriculture, increased production of other commodities, and trade within and beyond the Indian subcontinent.[83]
During the Satavahana period, several large settlements emerged in the fertile areas, especially along the major rivers. The amount of land under agricultural use also expanded significantly, as a result of forest clearance and construction of irrigation reservoirs.Most of the Satavahana inscriptions and coin legends are in a Middle Indo-Aryan language.[89] This language has been termed "Prakrit" by some modern scholars, but this terminology can be considered correct only if the term "Prakrit" is defined broadly to include every Middle Indo-Aryan language that is "not exactly Sanskrit". The language of the inscriptions is actually closer to Sanskrit than to the literary Prakrit used in the Gaha Sattasai anthology attributed to the Satavahana king Hala.
