As we know it
We all need fresh and pure water to drink. Water pollution poses a major problem in many countries. There may be several causes of impurity in water, which could be harmful and lead to diseases. There is a desperate need to get water purified and cleared of pollutants. Many filters available in the market claim to improve the taste and odour of water, but none of them specify the actual amount of impurities removed. The government also does not provide any data on this. Most of us use home water purification systems to clean water. The common home water purifier systems, which are widely used to purify water, have a carbon filter, which is a coconut derivative. It is a very safe and environmentally friendly option of water purification. These filters are also known as charcoal filters, which have either a form of honeycombed carbon or silver.
Need for Change
You can find a number of brands of water purification system or filters. But they need a change of filters after some time. The cost of replacement may be high and could weigh heavily on your pocket. Though they are eco-friendly, their replacement process is not so eco-friendly as they finally land up in the garbage. Water softener systems treat hard water but also remove essential minerals from water in the process. They are costly and consume a lot of energy, which increases the demand of eco friendly water purifiers
1. Acoustic filter:
Kolmir Water Technologies has developed an acoustic filter. It makes sound waves by using an ultrasonic generator, in water. These sound waves separate particles and make them aggregate and sink. Thus water becomes clean on the surface.
It has an ultrasonic generator; which produces sound waves in water. This filter can cut operating costs by more than 30 percent. Also, there is hardly any need to wash the filter.
2. The Ovopur:
The Ovopur has been designed by Manual Desrochers of Montreal. Made of porcelain and glass, it has a four-stage filtration system. It has a reusable glass filter filled with activated carbon, quartz, porous ceramic beads, along with a zinc and copper alloy. The filtered water is collected in a porcelain tank. It has a capacity of 11 liters and is free of lead and chemicals. It also keeps water cool.
It saves time and cost. It fills the tank in about 20 – 30 minutes and needs a change of cartridges after filtration of around 2,000 liters water. It is eco-friendly as its glass filters can be re-cycled.
3. Solar Water Purifier:
The solar water purifier uses solar energy for the purification of water. Dirty water is poured into a tray from where the water evaporates due to heat and the condensed water is collected on its cover. This water enters the second compartment. After purification the first tray is removed. Ultraviolet rays then further purify the water.
It is portable and can purify water even from natural resources. Some models use solar batteries too, so you can use it anywhere. It is cost effective as it can purify a large amount of water as compared with conventional purifiers. These batteries can be charged by attaching them to a car or any other power source and they can operate with the help of solar power. Portable solar water filters are of great use in emergencies. They can purify even dirty water.
4. Advanced Technology Whole House Drinking System:
It is used to clean the whole house drinking system. It has activated carbon and can improve taste and odor by reducing chemicals in tap water. It crystallizes particles present in water and they are washed off with water itself.
This system works on Nano technology. It crystallizes calcium ions into stable crystals, which can be washed away with water as they are small and cannot attach to any surface. This removes scaling from the whole house drinking water system.
Most of these water purification systems are still concepts. The design of the real products could be different and may also affect their performance. Prices could also be an issue, and affordability of these filters cannot be predicted.
