To solve this water pollution problem, many inventors have created a system which can purify water to fresh water called R.O system (reverse osmosis system).


First of all, we might want to how was this system been created? The R.O system was invented by the U.S Navy to put drinking water on submarines. It’s obviously that if any systems that can remove sodium and all the other mineral contents from sea water to make it drinking water that would be an incredibly effective system. And that what reverse osmosis is.

How does it work

How does this system work?

First of all, we have to make sure that the water that is going the R.O system is soft, ion-free, so that what have thought of before putting water into the system.

R.O system is one of the most effective ways to remove impurities without using expensive filters. This reverse osmosis water filter review is highly recommended by experts because of its usefulness and affordability, you can find great products with awesome features. Unlike other filters that must be frequently replaced for wasting the environment. This helps to produce clean water for your family’s need.

Most of reverse osmosis systems are now capsulated filters and they all work in the same manner. They have a pre-filter or a combo pre-filters which can take chemicals out of your water before reaching to the next filter. The second filter of the system is where the magic happen.  At this moment is the separation of wasted water to product water. The water comes in the small drain so if you get more water running to this filter then you probably got some problems with the system. Once the separation happens, it sends wasted water to the drain and the good water to your holding tank. The holding tank is usually a bottle with an extra air-pressured bag to help you keep a huge amount of water. So when you start using water from your own sink, the water is then forced out of the tank by air –pressured bag, pass through the last filter to purify one last time and then come out from the sink.

Benefits of using the system

But many people are having problems with using this battery, most of them were how to maximize the performance of their 18650 and how to use it properly. So today, I’m gonna show you my tips when using the 18650 battery. If you want more here is our 18650 battery review, hope you’ll find it useful.

Tips 1: Always buy the battery from trusted source.

26650 battery

Not just with 18650, I’ve always tried to purchase all the products that I want from a good source. It’ll cost you more but will definitely save more in a long run. Some of the brands that I’ve had the chance to use their products are Sony, Samsung, and LG. As far as until now, I’m very satisfied and totally agree with their price.

Tips 2: Never use the low-quality charger.

For your safety, please don’t buy a charger from unknown sources. Only use the charger that is recommended for your battery. Don’t get over-excited from a charger that could recharge your battery quicker than normal. This charge often uses a larger current power that makes your battery become full faster. But doing this too much will make your battery less stable and shorten its life cycle.

Tips 3: How to recharge properly.

Don’t discharge your battery, especially when the battery is almost full. This is called “deep discharge” and it’ll cause your battery to run out faster and less stable. Stop using the device if the battery temperature gets too high. It’ll shorten your battery lifespan and reduce its capacity.

Proper charger

Never charge your battery using high-current-charging. Most 18650 only use the charger that has the input of 1A. Although higher current may help you reduce charging time, there are more risks than what you can get.

Tips 4: Avoid overnight charging or charging in a long period of time.

Even though I’ve said that we should charge our battery with proper input, it doesn’t mean that you should just leave your battery with the charger plug in all night. There are a lot of things could happen during that time. Your input electric current could change suddenly, thus make the charger can handle it and cause a fire. Or your battery may get overheat due to being overcharged. This can shorten your battery lifespan, or worst, make your battery explode due to overheating.

Tips 5: Make sure that the plastic shell is in good shape.

Take a look at the cover of your battery, there shouldn’t be any damage on it. If there are, you need to consider changing your battery since it is a sign that your battery is often be overheated. Using your battery at this state is really dangerous and unwise.

Tip 6: Change the battery

Battery ran out

If your device is using multiple batteries, you need to replace all of them at once when you want to change the battery. If the power and capacity in each battery don’t cope with each other, the device won’t work properly.

Tips 7: Never let the battery ran out.

Leaving your battery without any power is the fastest way to make it become unusable. Remember to fully recharge your battery even when you don’t use it. If you need to put it away, remember to recharge first, then store it at somewhere dry and dark. Don’t let it expose to the sun or direct heat. When you don’t need your battery anymore, wrap it, put it in the specific trash can. Don’t mix battery with other types of rubbish. The battery might explode

Introduction about types of air compressors on the market

Currently, there are many types of air compressors on the market, for new users not much information will be easy to make mistakes, this article will give you a comprehensive understanding of the type of compressors on the market. It makes it easy to distinguish the types of compressors to choose the type of machine that suits your needs. Besides it, you can visit here for getting more information about small air compressor reviews

What is air compressor? – What is compressor used for?

Air compressor


Air compressors are machines (mechanical systems) that increase the pressure of the gasses. Compressors are used to supply high-pressure gas to industrial machinery systems to operate them, to start high-powered engines, to run compressed air engines or to machines and equipment of many. Other majors …

Types of compressors according to the mechanism of operation:

  • Circular motion compressors:

The compressor uses the circular motion of the screw using two pulleys connected to the two shafts of the gear into smaller volumes. They are used extensively when it is necessary to work continuously in commerce and industry and can be fixed or moved. Their working ability can range from 5 to over 500 HP, from very low pressure to very high pressure (8.3 Mpa).

This type is used to supply compressed air for many types of machine tools. They can also be used for engines with air intake pressure pumps such as cars or planes.

  • Moving air compressor:

Reciprocating motion compressor using a manual rotary piston. Can be fixed or moved, can be used separately or in combination. They can be controlled by electric motors or internal combustion engines.

Small-displacement piston compressors with a capacity of 5-30 horsepower are commonly used in automatic assembly and non-continuous motion applications.

Large air compressors can have the capacity of up to 1000 horsepower used in large industrial assemblers, but they are often not used as much as they can be replaced by moving compressors. Round of gears and screws at a lower price.

  • Centrifugal compressors:

Centrifugal compressors use turntable or wheel rotors to squeeze gas into the edge of the impeller to increase the speed of the gas. The diffuser of the machine converts the energy of the speed into the pressure. Centrifugal compressors are often used in heavy industry and continuous work environments. They are usually fixed. Their power can range from hundreds to thousands of horsepower. With a centrifugal compressor system, they can increase the output pressure by more than 10000 lbf / in² (69 Mpa).

  • Convection air compressor:
convection air compressor

Convective compressors use a rotor system in the rotor to compress the air flow. The stator’s fixed rotor located at the bottom of each rotor pushes the air directly into the rotor system of the next rotor. The space of the air path decreases gradually through the air compressor to increase the compression. Compressed air compressors are often used when high currents are required, such as in large turbine engines. In the case of a pressure ratio below the 4: 1 ratio, it is often the case that geometric adjustments are used to increase the efficiency of the operation.

  • Combined air compressor:

Compressed air compressors are similar to centrifugal compressors, but the velocity is symmetric at the rotor angle. Diffusers are often used to convert mixed air into convection. Combined compressed air compressors have a smaller diffuser diameter of equivalent centrifugal compressors.

  • Rolling air compressors:

Air compressors in rolls, similar to a rotary screw-operated rotary device, consist of two rolls of helical inserts for compressing air. Its output pressure is unstable by the use of conventional screw air compressors, so it is less used in industry. It can be used as an automatic loader, and in air conditioning systems.

  • Air compressors with filter:

Compressed air compressors are used to compress hydrogen and compress natural gas. General air compressors are located above the containers to hold the compressed air. Often, oil or free-flow compressors are used as much as oil enters the air stream. But in the case of compressors for divers, even the smallest amount of oil is unacceptable.

So in this post, I’m going explain to you how and when can your babies eat solid foods.

The proper age for feeding your child solids is between the sixth and twelfth month. And your baby must develop the basic skills to eat.

Common signs:

When they are ready for cereal, they will show you signs that tell you that they want solid foods:

  • They need to have a good head control and are able to sit upright.

  • They must lose the reflex to push solid food out of their mouth. This reflex is necessary when they are first born but they should fade away as your baby starting to grow.
  • He (or she) show interest in food. They begin to observe other adults eating, trying to reach for food, exciting when tasting new food, open their mouth when receiving food,…)
  • They are able to chew and swallow (starting to grow teeth, chewing stuff)
  • They become hungry even when being feed with 8 – 10 times of breast milk.
  • Their weight is about twice their birth weight.

And do not solid feed your baby too soon. Because babies that had been giving solid food before the 4th month has a higher risk of becoming obese. And giving them solid food too soon could affect their development. Infants still need mother milk until they turn 1 to be fully developed. You should combine feed your babies cereal along with giving them milk or formula.

Remember to introduce one food at a time and wait for 2-3 days for allergic signs. If your baby show signs like vomiting or diarrhea, you should have a talk with the baby doctor.

Add breast milk if you feeding your child with cereal. They will love it more and eat more.

And remember, breast milk or formula is still your child’s main source of nutrition in their first 12 months so don’t just rely on cereal or solids. And even when being fed with cereal, your baby still need the same amount of milk or formula.

You should feed your baby when he (or she) is having a good mood. Begin with a bottle of breast milk then start with the cereal to take advantage of the hunger. That way, your child won’t feel frustrated with the new type of food.

Make sure they sit upright, a feeding chair is the best for the job. While feeding, try to distract your babies by using a toy or goofing with them.
