What are the steps of purification of water?

There are several methods used in the water purification process, which include: (1) physical processes, such as filtration, sedimentation, or distillation; (2) biological processes, such as sand filters, active carbon; (3) chemical processes, such as flocculation, chlorination, the use of ultraviolet light.

What is the first stage of water purification?

Coagulation and flocculation are often the first steps in water treatment. Chemicals with a positive charge are added to the water. The positive charge of these chemicals neutralizes the negative charge of dirt and other dissolved particles in the water.

What is the best water purification method?

Reverse osmosis
Reverse osmosis works by moving water through a semipermeable membrane to filter out and flush away any contaminants. Reverse osmosis systems are best suited for domestic use and provide a highly efficient way to purify your drinking water at home.

What are the four methods of water purification?

When reverse osmosis is not available, there are 4 water purification methods that you can use to make your water safe for drinking.

1 – Boiling. Boiling water is the cheapest and safest method of water purification.
2 – Filtration.
3 – Distillation.
4 – Chlorination.

What is natural water purification?

Natural purification processes. Surface water contains inorganic and organic compounds of natural origin as suspended matter and dissolved substances. For drinking purposes, the contaminations in water must be removed or destroyed by purifying processes as completely as possible.

What are the general steps in purification of drinking water?

General steps in purification of drinking water includes. 1. Aeration: Raw water is first collected in large aeration tank and the water is aerated by bubbling compressed air through perforated pipes. Aeration removes bad odors and CO2. It also removes metal such as iron, manganese by precipitating then as their respective hydroxides.

How to purify river water naturally?

c)Using Natural water purification means: The most common natural means used in river water purification is a method known as Solar Water Disinfection or better known as SODIS. This method, as the name suggests, is the use of the sunrays to purify river water.

How is Mississippi River water purified?

Mississippi River water contains large amounts of suspended solids. As the river water enters the Carrollton Plant, the purification process begins with the addition of coagulant chemicals: ferric sulfate and polyelectrolyte.

How is river water purified at Carrollton?

As the river water enters the Carrollton Plant, the purification process begins with the addition of coagulant chemicals: ferric sulfate and polyelectrolyte. These chemicals are added to the process at very precise dosages and mixed rapidly with the river water to ensure efficient and complete coagulation.
