When you find yourself in a survival situation with no clean water at hand, it's important to know how to filter water so you don't make things more complicated by getting sick. Of course, if you have the luxury of advance preparation, you can choose more convenient options for your camping trip or even a permanent filter for your home. Then, let the water sit so the particles settle on the bottom before you pour the water into a cleaner container.
To do this, build a wood fire and let it burn out, leaving charred pieces of wood. Then, pack the charred wood tightly in a cloth and let the water drip through it and into another container to filter it. To learn how to choose a store-bought filter or make a ceramic filter for your home, keep reading!

A vacuum filtration is usually faster than a simple gravity filtration.
However, there are several points that have to be considered. A vacuum filtration is usually faster than a simple gravity filtration using a simple conical funnel. However, there are several points that have to be considered when performing a vacuum filtration. Due to the fact that reduced pressure is used in this procedure, special attention has to be paid to the equipment used in this procedure. The glassware i.
It is also imperative that the filter flask and the vacuum trap are clamped securely, so that they do not move during the filtration. The thick-walled tubing tends to act like a whip sometimes, and slams the filter flask into the hotplate or other metal objects resulting in an implosion or tips the flask over and the product is found afterwards on the bench or even worse on the dirty floor!
The clean filter flask and the vacuum trap consist of heavy-walled glassware. Thick-walled tubing should be used as well. Normal tubings that are used as water hoses will collapse when a vacuum is applied! Never perform a vacuum filtration without a vacuum trap. It is also a good idea to keep the trap clean, just in case something gets sucked in there.
It is easier to recover it from a clean trap then from a dirty trap. Vacuum filtrations can only be performed with funnels that have a flat surface e. The filter paper has to cover all holes in the bottom of the funnel and does not extend up the sides. If the filter paper has the wrong size or not properly placed in the funnel, a significant part of the solid will "run through" the filter paper.
From this point of view, it might be a good idea to generate a cardboard blank from an existing filter paper. The filter paper is moistened with the solvent that makes up the solution.
This prevents the formation of multi-layer systems in the filter flask. It should adhere well to the bottom before the vacuum is applied. Then the solution is slowly poured slowly into the funnel. Figure 2: Hirsch funnel with filter paper, all holes covered. When a funnel is placed on top of the filter flask, a neoprene adapter the black or gray "rubbery thing" or rubber stopper is used to ensure a good seal between the filter flask and the funnel.
When the filtration is finished, the tubing from the filter flask should be removed before the vacuum is turned off. This is less important when the house vacuum line is used like in the instruction lab, but it will be when an aspirator is used. The low pressure in the filter flask sucks the water back into the mother liquor, and if this is the part of interest, the experimenter is in big trouble.Assume that you have business data consisting of around rows like below.
Now if your manager comes to you and asks for a list of top 10 clients and the minimum amount of the Top clients. What will you do to find top clients in the database? Then you will paste the First 10 rows in another sheet and then apply the MIN Function to get the minimum amount of the top 10 clients. But if tomorrow your criteria change to something else, then will you will have to do the same thing with another criterion?
Very tedious task. You may argue that If you use MIN function for entire data set without copy-pasting the first 10 rows. My answer to this that the function will return the minimum value of the entire data set and not the top 10 values.
Before you start doing subtotal function you have to apply the filter. As soon as you click on Top 10, another new box will appear and be looking for your confirmation. You can choose the desired number from the box and then click ok. Here is my example, it is By clicking on OK you will get the list of top 10 clients. I recommend that you should check out other variants too.
The excel advanced filter techniques are handy for many challenges you face at work Now you want to check which is the Minimum Number. Here you cannot use the Min function because MIN function will select the entire range including the hidden rows and will give the result from your dataset and not from the filtered data.
Excel is smart. Our aim is to find out the minimum numbers from these 10 records. Now change the number subtotal 9 to subtotal 5because subtotal 9 is used for Sum and subtotal 5 is used for Minimum. And then Press enter. You will get the minimum number of your filtered data.
You go to your amount filter dropdown. And this time in case of 10 chooses only Top 5. You will get the minimum number from the Top 5 Clients. Similarly, you can use different numbers for a different function. You can use number subtotal 9 for Sum, number subtotal 4 for Max etc. It will come up automatically but you need to remember the logic. They write Subtotal excel formulas manually and then put the numbers 5 or 9 indicating what they are looking for but they make the selection manually.
If you look very closely at the selection, it starts from 11th Row actual data Starts from 4th row and ends in th row actual data ends in th Row. It does not take the extra date which is hidden between th and th row.
Now if you look very closely at the function box for subtotal excel formulas it shows like above. This is widely used as Excel advanced filter technique.
Maybe, we all can learn something from your practical use cases.Fish tank cycling can be a slow and painful for some :P process. In the case of fishless cyclingsome people might become impatient. There are certain things we can do to finish the aquarium nitrogen cycle a lot faster. All the new fish tanks start with near zero beneficial bacteria of both types.
Nitrosomonas for converting ammonia, and Nitrobacter for converting nitrite. It takes time for them to multiply to a level where they can make an impact on the ammonia and nitrite.
More importantly, Nitrobacter will not even start to grow in number at all until there is nitrite in the water. For nitrite to appear, there must be enough Nitrosomonas to feed on and convert ammonia first. It is a bottleneck right there to slow everything down. We should make both stages starting simultaneously from the beginning. The whole aquarium cycling can be a lot faster.
A good filter 2. Heavy bacteria seeding 3. Higher water temperature 4. Higher oxygen level 5.
5 Air Purifying Tips for Cleaner Air in Your Home
Keep nitrate low. Since most of the aquarium nitrogen cycle bacteria reside on the filter media, it is essential to have a good aquarium filter. A good filter means it not only has plenty of filter media for massive bacteria colony, but it also has high water flow rate.
Canister filters have the most filter media, and it is highly efficient for biological filtration. Whatever filter system you choose for your aquarium, get one that is rated higher than your fish tank size is also a good idea. The higher size fish tank the filter is rated for, the more filter media and more flow rate it has. You can never have too much filtration in a fish tank. To have some beneficial bacteria to start the aquarium nitrogen cycle will undoubtedly speed up the fish tank cycling.
More importantly, to have both Nitrosomonas and Nitrobacter to begin the cycle from the very beginning can be a tremendous jump start. Because it eliminates the waiting period for nitrite to appear. Traditionally people seed bacteria by using something from an already established aquarium. It can be a decoration or some gravel. The best thing to use in this case is a piece of filter media.
Most of the beneficial bacteria colonize the filter media. By placing a piece of filter media from a well-established aquarium into a new filter, you can give quite a jump start to the aquarium nitrogen cycle.
Since not everyone has access to a well-established aquarium, this form of bacteria seeding might not be available. Nowadays, there are commercially available bacteria seeding products. They are great for the jump-start the aquarium nitrogen cycle in new aquariums if you are willing to spend a little extra money.
There were some old bogus products with incorrect species of land-based bacteria in them.What happens when you find yourself without access to clean water? Access to clean water could be the difference between life and death in a survival situation.
Good for: Getting rid of dirt and debris. Directions: Run a strip of washcloth from a container of dirty water to an empty container. Eventually the water will migrate from one to the other, but it will still need to be boiled to eliminate contaminants.
Good for: Killing bacteria and disease.
Anyone can boil water in a basic teapot, but PREPARED Survivalists will use the kettlecharge — a kettle that can charge your devices as it heats and purifies your water. Directions: Pour water into a pot or kettle over an open flame. Bring to a boil. Allow the water to boil for at least 10 minutes to make sure all microorganism are killed.
Good for: Filtering out all contaminants. You will need: Aquastiq and body of water. Directions: When proper supplies are available, Aquastiq can be a literal lifesaver. The Aquastiq allows you to safely drink directly from rivers and lakes. Purifying Water in a Survival Situation. Make Water Drinkable.

I look forward to growing with you! In need of a clean water source, but no fresh river in sight? One container will remain empty, and the other will contain your unclean water source. Dip one end of the cloth into the dirty water container, and let the other dangle into the second empty container.
Aside from the benefit of giving people more time for uninterrupted focus, asynchronous communication predisposes people to better decision-making by increasing the amount of time we have to respond to a request. Eisenhower, who, quoting Dr. The urgent are not important, and the important are never urgent. To optimize an asynchronous message and to avoid a lot of follow-up emails, include the following in your initial request:.
Rather than sporadically checking things throughout the day, we should batch check email, instant messages, social media, and even text messages, at predetermined times.
Blocksite and the Freedom app also allow you to block access to specific websites and apps during specified intervals. This could be as simple as a pair of headphones. Alternatively, consider blocking out meeting-free zones on your calendar, or using a meeting scheduling tool such as Calendly so that people book meetings with you only during scheduled windows, leaving the rest of the day free for focus, and ensuring that you avoid the email tennis matches that scheduling meetings often degenerates into.
Instead of risking follow-up interruptions and a meeting to discuss the previous meeting, ensure that you leave each meeting with actionable next steps, clearly assigned responsibilities, and due dates. Take more ownership over your decisions and only email people who need to be informed.
The average executive receives 46 push notifications per day. To avoid our Pavlovian impulses to respond on cue, simply turn off your push notifications. Find out how here. You can also use airplane mode to limit text message and phone call interruptions during certain times of day.
If the idea of doing this gives you anxiety, you can always exempt specific numbers, such as those of loved ones or valued and important business associates. Environmental changes aside, human beings evolved to conserve energy in order to stand a shot at surviving on the savannah. As such, we are predisposed to picking the lowest hanging fruit or doing the easiest thing first — think checking email instead of working on that presentation.
Becoming more aware of our tendencies to pick the low hanging fruit, getting distracted by low-value activities, is step one towards changing our behaviors. Organizations that build a culture around minimizing distractions will enjoy the compounding benefit of a focused workforce and will leave their people feeling less stressed and ultimately more fulfilled.
