Water purification is the process of removing undesirable chemicals, biological contaminants, suspended solids and gases from water. The goal is to produce water fit for a specific purpose.
According to the 2007 World Health Organization (WHO) report, 1.1 billion people lack of adequate drinking water, 88% of the 4 billion annual cases of biennial disease are responsible for unsafe water and inadequate sanitation and hygiene, while 1.8 million people die from diarrhea every year.
Some water borne diseases include cholera, typhoid fever, gastroenteritis, schigella, polio, meningitis, hepatitis A and E, amabassis and diarrhea etc.
Reducing the deaths of waterborne diseases in developing countries is a major public health target.
Water boiling is the most popular and traditional method of home water treatment. But excessive boiling of water removes essential nutrients. It can sometimes not remove the ominous particles. Even the taste of boiled water is not very good financially, this process consumes a lot of gas and hence it is also expensive!!
2. Filter the water
Perforated water is considered clean water. Filters usually remove dirt and impurities but do not necessarily remove harmful bacteria and viruses. These harmful bacteria can cause stomach disorders. In our country where most water sources are polluted with polluted substances of sewage, the filter of water cannot be a very good decision. Apart from this the filters are often damaged and over time, the capacity of the cleaning becomes loose and it needs to be replaced.
All pathogens including viruses have been kills / disabled, but their bodies live in water. TDS and hardness cannot be reduced.
In RO systems, some contaminated substances such as arsenic, nitrates, copper and lead, some biological chemicals and municipal additive fluoride are removed. It removes impurities and germs from water and makes it suitable for drinking.
Different in UF , UV And RO
UF Water Purifier
No need of electricity. Blocks and removes all germs and viruses from purified water. UF will function with normal tap water pressure
Cannot remove dissolved salts. Works with muddy dirty turbid water
UV Water Purifier
Requires electricity to work. Kills/ Deactivated all germs including viruses, but their bodies remain in the water, Cannot remove dissolved salts. Water must be clear for UV to work.
RO Water Purifier
Reverse Osmosis (RO) is a water treatment process that removes contaminants from water by using pressure to force water molecules through a semipermeable membrane. During this process, the contaminants are filtered out and flushed away, leaving clean, delicious drinking water.
Requires electricity to work, Blocks and removes all germs and viruses from purified water. RO requires electricity to boost tap water pressure. Removes dissolved salts.
Remove sand silt, dirt, and other sediment
Pre / Post Carbon filters:
Remove chlorine, chemical, which can damage the RO membranes and any remaining tastes or odors are removed from the product water by post filtration “polishing” filter.
Reverse Osmosis Membrane:
Reverse Osmosis Membrane is the heart of the system. The semipermeable RO membrane is designed to remove a wide variety of both aesthetic and health-related contaminants. After passing through the membrane, the water goes into a storage tank where treated water is stored.
Water flowing through the RO membrane is regulated by a flow restrictor. There are many different styles of flow controls, but their common purpose is to maintain the flow rate required to obtain the highest quality drinking water (based on the gallon capacity of the membrane). The flow restrictor also helps maintain pressure on the inlet side of the membrane. Without the additional pressure from the flow control, very little drinking water would be produced because all the incoming water would take the path of least resistance and simply flow down the drain line. The flow control is most often located in the RO drain line tubing.
Besides periodical cleaning of RO membrane, the maintenance and servicing of the Reverse Osmosis (RO) Plant shall consist of following:
1. Micron Filter/ Sediment should be replaced during every servicing.
2. Cleaning of Sand filter.
3. Cleaning of Activated Carbon Filter
4. Anti scaling dosing chemical (As per requirement)
5. Raw water pump (Checking/servicing, if required)
6. R.O. Membrane (Checking/ Replacement, if required)
7. High pressure pump (Checking/servicing, if required)
8. Checking of flow rate of membrane & TDS on site
Chimney and exhaust fans for kitchen in India has become essential now. In the old days, houses had space for air and fresh air used to fill the kitchens from open windows.
Things have changed now with flat living and modern houses that have no chimneys.
The burning gas in the kitchen uses oxygen in air of the kitchen and converts it into mainly hot carbon dioxide and steam. Some poisonous carbon monoxide gas and other unhealthy gases also form during the combustion of LPG gas.
When frying Indian masalas in oil, pungent masala fumes together with burnt oil fumes are all over the kitchen air. People in the kitchen and in the surrounding rooms, including children, are breathing in this air which is not good. The polluted kitchen air causes a lot of health problems like feeling dizzy due to lack of oxygen, headaches, nausea, nose problems like sinusitis, eye problems, allergic reactions like asthma, etc. etc. So it is in everybody's interest to make sure that the all cooking gases are exhausted from the kitchen as efficiently as possible.
That why now in modular kitchen need chimney .
