Type: Electrolysis

Pros & Cons:

  • Can only be used to separate acidic water and alkali water, hence have no filtering function and must be used with activated carbon to have filter purposes.
  • Acidic water is more commonly recommended to be used for washing and showering, as it is suggested to have beautifying function.
  • Alkali water is more commonly recommended to be used as drinking water, as it can help balancing our body’s pH value, however it is advisable to drink with caution as pH value that are too high may not be suitable for daily consume, especially for infants.
  • During its process it may produce 50% wasted water that ought to be poured, thus has low efficiency and needs to be charged 24 hours in order to work.

tap

Type: Ozonation

Pro & Cons:

  • Can be used to remove odor, colour and kill bacteria through ozonation
  • However the efficiency would be affected by external factors such as water temperature, concentration of ozone and time of ozone contact with the water.
  • Has low efficiency in filtering organic or non-organic pollutants.
  • Can produce peroxide substance that are harmful and toxic to our body.

How Safe is Our Water?

The earth is pretty much covered by water with only less than a third is taken up by land. Back to 100 years ago, or perhaps centuries ago where the Industry Revolution had yet occurred, the Earth was healthy with its clean air, clear water and full of greens. However, as the Earth’s population continues to grow and advanced, being more civillised does not mean we are treating our environment well. More than often, we take the environment for granted and had caused severe pollution the the Earth. Due to greed and inconsideration of humans, pollution has only ever gone worse and had only came to our attention after it had became a serious issue for our future, where the Earth have starting to show signs how human had exceeded the nature’s limits.

So you may ask ‘How serious is the problem?’

According to the environmental campaign organization WWF: “Pollution from toxic chemicals threatens life on this planet. Every ocean and every continent, from the tropics to the once-pristine polar regions, is contaminated.” Hence, it is a dead serious issue where it can threaten the entire ecosystem if we let the issue drag on and make no changes in our lifestyle.

There are many pollutants that can be found in water nowadays, and be it for the purpose of using or drinking, these pollutants are not safe for any living beings. However, most of the water filters by Cuckoo can eliminate these problems.

Alt_Plastics in our oceansentering the food chain
Plastic

Pollution Cause:
Industrial wastage from fishing (plastic fishing lines), littering from visitors to beach areas (plastic bottles and plastic wares),

Possible effect on health / environment:
It is not as toxic as other chemical pollutants, however can cause a major hazard to the marine creatures, and bring back the plastic into our digestion system throughout the food chain process while consuming marine products.

toothpaste microbeads

Micro Plastic Beads 

Pollution Cause:
They are often found in most facial cleansing products and body shower products, where the beads are designed to be so small and insoluble in water, we end up flush them away through water and released to the sea after the water process, which can prevent us from having clean and drinkable water, also harms the ecosystem.

Possible effect on health / environment:
Can affect our digestion system by clogging and cause malnutrition in marine creatures.

Methyl-tertiary-butyl-ether-MTBE-Plastic-can-5Litres-600x600

MTBE ( Methyl tert-butyl ether)

Pollution Cause:
It is a chemical substance contained in unleaded petrol, given its sparingly soluble characteristics, it shows no colour in the water. It can also lead to unpleasant taste and odor in water due to its vague reminiscent of diethyl ether. It is often caused through leakage of underground oil tanks or pipes.

Possible effect on health / environment:
Causes cancer, nausea, damages the respiratory and neural system

Chlorine

Pollution cause:
It is commonly added by water suppliers and manufacturers to kill bacteria, however overdose of chlorine can be toxic and cause unpleasant feeling while drinking the water.

Possible effect on health/ environment:
Chlorine is believed to contain a carcinogen which has been linked to seven different diseases including diabetes and birth defects.

Oil

Pollution Cause:
88% of oil were spilled from routine shipping and caused by people pouring unused oil down drains on land, where only 12% of oil came from tanker accidents.

Possible effect on health / environment:
Can destroy the marine ecosystem as oil layer can block oxygen from entering water. Massive oil spill can cause intertilisation of marine creature’s eggs and also endanger their life by affecting the quality of water.

Mercury

Pollution Cause:

Industrial waste from factories, leakage of factory pipe

Possible effect on health / environment:
Can cause mercury poisoning where also leads to muscle weakness and poor coordination, skin rashes, memory problems, damage the hearing, sight and neural system.

——————————————————————————————————————

There are many other substances that can be found in the water which is not safe for living beings and the ecosystem. In order to make water drinkable, besides of using water filters to purify water source, immediate action needs to be taken to mitigate effects of pollution with strict laws and proper education.

 

How to Choose the Best Water Filter for your Household

Our earth is no longer healthy and we cannot just drink or use water directly from the pond, lakeside or the river nearby us in the wild. As the water we have now is already polluted due to industrialization and irresponsible care from humans. Water pollution can be disastrous and could cause a lot of problems to our health if we had consume them, or had contact with them. It is even worse for other countries which are underdeveloped as they clearly had no clean water for them to consume or use.

Scientifically proven, water is an essential element to maintain our health as our body is 70% made of water. Hence, to have the best quality of water without any pollutant is a vital concern for every household, as polluted water may cause a lot of health problems if they are contaminated with substance such as dirt, heavy metal (mercury, lead) which could lead to poison and other mental problems; nano-plastics that are insoluble in water which could cause digestion problems and etc. Given that our living environment now is advanced with technology and scientific knowledge, there are many inventories that are able to filter the unwanted substances in water, so that we can drink or use them safely in our lifestyle.

There are currently a variety of choices for us to choose for water filters in the market, and each brand’s water filter may seem different from each other on their functions, price and also durability. One of the famous brand on water filter is Cuckoo. Nevertheless, brand is not the main issue here. All we need to know, is the function that we really need based on our living environment and the quality of water supply, so that we can choose the most suitable water filter to cope with our environment to have the best quality so to optimized our health.

Firstly, it is important that the water filter can separate dirt from the water, as water may flow through pipes that are aged for decades or centuries, and the source of water may be from underground, or contain possible dirt while flowing from the source to our house. To have clean water, dirt is the first thing that we would not want to see in the crystal clear water.

Secondly, do take note if the water filter contains carbon filter that are specially designed to remove lead. And of course, try not to use hot water directly from the tap, as they are likely to contain higher levels of lead. It is advisable to heat them up separately if you need hot water, so to reduce the level of lead as much as possible from the tap.  This is because most of the lead in household water usually comes from the plumbing in your house, not from the local water supply. Nevertheless, a good water filter should handle this problem perfectly, so that we won’t be drinking lead-contaminated water.

Thirdly, if your living environment or water supply has its source located at a rather high density of minerals, it is advisable for you to choose water filters that uses reverse osmosis. This can filtered most of the excessive minerals contained in the water, including calcium, magnesium, sodium and etc.

Lastly, you need to check reviews of the water filter that you are going to purchase, and take note on reviews on their service quality, customer service, after-sale service, warranty and maintenance when deciding which brand to purchase. As different companies may have different policies other than functions that are suitable for your household!

 

FIELD REPORTS: Oregon and Montana

The John Day River in northcentral Oregon is the secondlongest free-flowing river in the continental United States (the Yellowstone is the longest). It supports abundant fish as it winds through scenic, pristine country proposed for wilderness designation.

Scenery, outdoor recreation and other natural assets are important for the region’s prosperity. Alex Phillips, the Sonoran Institute’s John Day field coordinator, is collaborating with organizations and local leaders to integrate protection of the river with local economic aspirations.

Our John Day partners include: the Bureau of Land Management, Confederated Tribes of Warm Springs, several state agencies, local governments, John Day Basin Trust, Oregon Natural Deserts Association, Sustainable Northwest, The Nature Conservancy, and the Wild Salmon Center.

Alex is one of two new Institute field coordinators promoting long-term conservation and prosperity in special places. After working with residents of Montana’s Rocky Mountain Front for the past few years, the Institute hired local citizen leader Corlene Martin in January as our field coordinator there.

Along the Front, a rural area with miles of open space, spectacular views and wild lands, the Institute advocates a solid land-use planning foundation and community visions that incorporate conservation.

Corlene works with communities on the Front, each with a set of challenges related to growth and economic vitality. We are helping Choteau design a city growth policy, while in Dupuyer and Augusta the focus is on water issues and economic development opportunities.

The Institute studied the region’s economic strengths and weaknesses and made recommendations for businesses and communities in this place where prosperity and quality of life are inextricably linked to conservation of its natural assets. This research is the basis for ongoing public education about agriculture, geo-tourism and community development.

The Institute also works collaboratively in the area to complement the efforts of other organizations, such as The Nature Conservancy and The Wilderness Society. With the National Parks Conservation Association and National Geographic Society, we are identifying the shared values of the Crown of the Continent region, including the Rocky Mountain Front.
