A Wonderful BBQ Wedding

My high school best friend was getting married in Italy. She hosted a BBQ wedding on a piece of big grassland. Honestly, I wasn’t really interested in joining the party at the beginning as it took me 12 hours to land there. But turned out this trip and the party were so much wonderful.

The BBQ party was the highlight of the wedding and it started at evening. The fuel they used was coconut shell charcoal instead of gas or coal. This reflected the couple as Earth lovers and the wedding theme as natural. One of the benefits using coconut shell charcoal is that there’s no smoke. Guests could chat and socialise easily without being “covered” by the smoke.

Because of the consistent heat for over four hours using coconut charcoal made it a very a convenient method of barbecuing (and also economical). There’s no need for anyone to replenish the grill with more fuel during cooking. After the party, there was little ash produced that allowed us to clean grill a lot easier after barbecuing.

This really inspired me and I tried to use the same fuel for barbecuing with my kids after going home. Well, I can say, coconut charcoal is definitely one of the cleanest and cheapest ways of enjoying a grilling meal. It’s really something which should be given a thought as once you switch to coconut charcoal you won’t feel like trying another fuel for your grill. There’s no health risk, which is my particular concern for the kids, and the meat tastes just as it is. I even find it amazing as there’s no interruption in the middle to refuel my BBQ.

Carbon FAQs – What raw materials can be used to made carbon?

Basically, any carbonaceous material can potentially be activated. The common raw materials include, for example, wood (soft & hard), coal, coconut shells, peats and others. Since activated carbon is manufactured from naturally occurring raw materials, its properties will vary. It is necessary to understand the nature of these raw materials, if you would want to purchase carbon for whatever your purpose.

Wood may be activated by one of two methods, i.e. steam or chemical activation, depending on the desired product. The carbon is usually supplied as a finely divided powder which since produced from waste materials such as sawdust, is relatively cheap and can be used on a “throw-away” basis.

Coal is also a readily available and reasonably cheap raw material. The type of activate obtained depends on the type of coal used and its initial processing prior to carbonisation and activation. It is normal procedure to grind the coal and reconstitute it into a form suitable for processing, by use of a binder such as pitch, before activation. Generally, coal contains bigger pores that make it a fairly well adsorbent for gas and air application.

Coconut shell is another common type of raw materials. It contains about 75% volatile matter that is removed largely by partial carbonisation, to minimise shipping costs. The iodine number is high of coconut based carbon, which indicates a higher adsorption capability for molecules. The ash content is normally low and the hardness is relatively higher that makes the carbon hard to breakdown in water. Because of these features, coconut-carbon is a very good filter media for water, beverage and air industries to produce cleaner liquid and air.

DIY Activated Carbon?

We are sometimes asked, “Please show me how to make activated charcoal at home.” But first, you need to understand team activation, one of the most common ways to “activate” carbon.

Handmade Steam-Activated Carbon
Is it possible?

Steam-activation is primarily used for coconut charcoal and coal. In the production of steam-activated charcoal, first the coconut shell or coal is heated to create a char. This char is then activated high temperatures of 1,700° to 1,800°F with steam in the absence of oxygen. The activated charcoal is then cooled off. The very high temperatures required for steam activation is impossibly achieved in a conventional oven (260 °C). Thus, this method is all but limited to industrial technology.

Another huge limiting factor is the cost of production. The world today uses a huge amount of activated carbon annually and so production has to be on an industrial scale to control the price. Even if money was not an issue, the quality would likely also be an issue, since cooking temperatures and times that require professional knowledge are critical.

So, how can you make steam activated carbonactivated carbon produced by trusted carbon manufacturer. This is the most effective and yet affordable way.

Which type of GAC filter system do I need?

A filter with granular activated carbon (GAC) is a proven solution to remove certain chemicals (in particular organic chemicals) from water. There are commonly two types of GAC filter system, including a whole-house filter or a point of use filter. Each system has its own features and is used in different applications. Sounds confusing? Don’t worry. Here it’s a guide for to find out your Mr. Filter.
There are several factors to consider:

The type and amount of contaminants in the water,
Other chemicals in the water,
Water use, and
Exposure pathways that need to be eliminated.

For those who have no clue about exposure pathways, exposure pathways are the ways chemicals enter your body. Some chemicals may cause harm if they are ingetsted while some are harmful if they are breathed in, some if they enter through the skin. Sometimes people are exposed through a combination of exposure pathways.

An under-sink filter protects people from ingesting the chemical by treating the drinking water only from that tap. It will not protect people from inhaling the chemical while showering or bathing, nor will it protect other water faucets.

A whole-house filter system treats all water traveling to any faucet in the home. It removes the chemical before it can be ingested, breathed in, or absorbed by the skin during washing or bathing.

Remember, no matter which filter system you’ll use, use only a licensed filter supplier. For either type of filter system, consistent maintenance and periodic filter or GAC replacement is essential to ensure effectiveness and prevent bacterial build-up.

Activated Carbon and Air Filters

Activated carbon is carbon that has been treated with oxygen. After the treatment, millions of tiny pores are activated on the carbon’s surface. Amazingly, these pores are so numerous that a single pound of activated carbon may provide 60 to 150 acres of surface area to trap pollutants.

Once carbon has been activated, it can remove a bunch of airborne chemicals, for example, alcohols, organic acids, aldehydes, sulfur dioxide, sulfuric acid, and phosgene. It also removes odours, whether they are from humans or animals. It also removes perfumes, other household cleaning chemicals, and is especially good at removing volatile organic compounds (VOCs).

Activated Carbon and Filters

Activated carbon filters will adsorb even a small amount of almost all vapours and they have a large capacity for removing organic molecules like solvents. They can also simultaneously adsorb many different kinds of chemicals, making these filters very efficient. Activated carbon is very durable and non-toxic, so it can work in any temperature or humidity. These make it’s safe for people to handle. As an extra bonus, activated carbon is also relatively affordable.

The trick lies on adsorption – the process by which a gas bonds to the surface of a solid. In this case, the solid is the activated carbon. Air passes through the filter where airborne gases, chemicals, and odours produce chemical reactions with the surface of the carbon, effectively sticking to it. The clean air then flows out of the filter.

Activated carbon filters is analogous to a sponge. The more activated carbon in the filter, the more pollutants it can hold and the longer the filter lasts. The best and the most efficient filters include many pounds of activated carbon to ensure a longer life before the next replacement.

Need some fresh and clean air at home? It’s time to put a good activated carbon filter at your home.

Moms-to-be, be aware of air pollution

When you’re pregnant, there are many things you’ll pay extra caution. The food you eat or the quality of your sleep. However, there’s something important but is also inconspicuous that many pregnant women may well neglect. That’s the quality of the air you breathe for you and your baby.

Air quality is important for us, and it’s particularly critical for those who are pregnant. Studies done by School of Public Health in Columbia University, New York, have shown that kids who are exposed to the highest levels of air pollution before birth have a greater risk of attention deficit hyperactivity disorder (ADHD) symptoms than their less exposed peers.

Those harmful pollutants that are hazardous to the prenatal are the products of fossil fuel combustion, and are known to damage the developing nervous system. Traffic exhaust and residential fuel oil use are the main sources of the combustion.

In response, New York City has already reduced levels of such pollution by establishing anti-idling regulations for trucks and buses, and requiring the city buses to use cleaner fuels. Meanwhile, pregnant women who are concerned about the risks of pollution exposure have their own responsibility. Eating plenty of fresh produce can give good nutrition to offset the effects of pollutants.

On the other hand, while we cannot control the outdoor air we breathe, we still can make our indoor air clean. Find a trustworthy supplier and use qualify air filters in your home. After all, we don’t spend most of the time outside, right?

Airport and Air Pollution

Smoke Solution>
I am a frequent traveller and have been to many airports. Airport is the first impression of foreigners to a country. A clean and fresh airport can always give a nice start of the journey. For years, I could find myself enjoying different airports and sometimes found it even nicer to have an overnight sleep there than a local hostel. However, in recent years I witnessed some unpleasant changes.

Demand for air travel is now higher than ever, thanks to cheaper tickets and easier technology. Anyway, the growing demand has mainly led to two consequences: more flights (including those of delayed) and more passengers staying in the airports. These will in turn increase the level of air pollution at airports.

More airplanes mean more sources of pollution. And more people mean heavier ground traffic needed to support air operations: push-back trucks, passenger or staff buses, baggage load, catering vehicles, just to name a few. Most of these articles are powered by diesel engines and operate closely to the airports.

The logic here is simple: airport buildings are ventilated to provide breathing air for our comfort. Large amounts of external air are now drawn into the buildings and this air will be heavily polluted. As a result, I witnessed the overall degrading air quality in some airports.

Controlling passenger flow is not easy. The more effective solution is to equip the airport with highly efficient air filters that can control particular and molecule pollutants. Assess the extent of the problem and tackle it with respective types of air filters. Also find the airport with qualify filters that are satisfy European standards.

Airports are the first check-point of foreign guests, don’t disappoint them.

Polar bears and their missing homes

What do you think about the picture? Polar bear doing yoga? This is not a picture for fun, but indeed, it’s a heart-breaking one that tells a big story.

The seawater surrounding the bear was once a piece of huge iceberg and the homeland for polar bears. But since the recent century, the Earth’s temperature has increased 0.8%, declaring the age of global warming. Humans are the main cause of global warming. We produce excessive CO₂that traps the heat inside the atmosphere.

We cause global warming but we’re not the only species that have to bear the consequences. Hotter temperatures melt the ice. Polar bears have evolved for a life on the sea ice, which they rely on for reaching their seal prey. But the arctic sea ice is rapidly diminishing due to a warming earth, affecting the entire arctic ecosystem. For polar bears, sea ice losses doesn’t only mean higher sea level (that can increase the risk of drowning!), but also means the reduced access to food, lower cub survival rates, and the loss of their homeland! Polar bears are now forced to swim longer distances due to decreasing sea ices.

Humans have led this problem. And we are the ones who have to fix it. Time to conserve polar bears is becoming stringent. This means all of us – individuals, communities, businesses, and states – must work together and act now.

The Best Solution for Your Water Problem

Ever suspected your water quality? It looks yellowish? It happens to smell like steel? Or it even contains some “unknown” substances? Then you tired different methods to clean the water but nothing worked. What’s the problem?

Indeed, the practicalsolutions to your contaminated drinking water problem are to stop the practices causing the contamination or to change water sources. While changing water sources can be hard or even impossible sometimes, stopping the particles becomes the best solution.

Try Activated Carbon (AC). AC is not necessarily the same as carbon. AC is a black, solid substance resembling granular or powdered charcoal. It is extremely porous with a very large surface area. One ounce of AC has an estimated 30,000 square yards of surface area. Thus, AC removes far more contaminants from water than does of ordinary carbon.

Activated Carbon (AC) filters can remove many organic compounds, such as chlorinated and non-chlorinated solvents. They can also effectively remove chlorine and is moderately effective in removing some heavy metals. Meanwhile, AC can also remove taste and odours in your domestic water treatment systems.

Today, home water treatment using AC is among the best and popular optioused by people with a drinking water quality problem. Your selection of an AC filter should be based upon water analysis and a thorough assessment of your homeowner’s situation. A well-informed decision is always your best insurance for protecting health.

Activated Carbon & Water Filters

Carbon is a substance that has a long history of being used to adsorb impurities and is perhaps the most powerful adsorbent known to man. One pound of carbon contains a surface area of roughly 125 acres and can adsorb literally thousands of different chemicals. Activated carbon is carbon that is electro-positively charge, making it even more attractive to chemicals and impurities. As the water passes over the positively charged carbon surface, the negative ions of the contaminants are drawn to the surface of the carbon granules.

Activated carbon filters used for home water treatment typically contain either granular activated carbon (GAC) or powdered block carbon. Although both are effective, carbon block filters generally have a higher contaminant removal ratio. The two most important factors affecting the efficiency of activated carbon filtration are the amount of carbon in the unit and the amount of time the contaminant spends in contact with it. The more carbon the better. Similarly, the lower the flow rate of the water, the more time that the contaminants will be in contact with the carbon, and the more absorption that will take place. Particle size also affects removal rates.

Activated carbon filters are usually rated by the size of the particles they are able to remove, measured in microns, and generally range from 50 microns (least effective) down to 0.5 microns (most effective).

The most common carbon types used in water filtration are bituminous, wood, and coconut shell carbons. While coconut shell carbon typically costs 20% more than the others, it is generally regarded as the most effective of the three. All of our activated carbon filters use coconut shell carbon.
