Features of a Water Purifier

As essential as water is to our survival, many problems can arise when we consume contaminated water. There are so many water sources which include wells, reservoirs, rivers and even rain water. These water sources though natural, have been found to be heavily contaminated and can cause many ailments if consumed as is. Tap water is widely believed to be free from contaminants but this also has been found to be false. Water purifiers have become increasingly necessary to ensure we have safe drinking water for consumption.

Water purifiers come in different types and brands; each using a filtration technique or a combination of two or more techniques and each claiming to be the leader in the water purification arena. It is very important to know the filtration techniques each brand or product provides and how effective it is for your water needs before going ahead to purchase the unit.

Water purifiers can be classified into the following types;

Distillation: In a water purifier that is based on the distillation principle, water is brought to its boiling point and the vapors produced are collected to give you purified drinking water. Distillation removes contaminants, sediments and microorganisms, leaving you with pure and safe drinking water. This process can be slow, time consuming and produces an output of about 1/10th of the total input.

Activated Carbon: Activated carbon is widely used to filter water. When the water flows through the carbon surface, the contaminants adhere to the activated carbon, giving you clean drinking water. This process does not kill the microorganisms in the water so it is not perfect, so to speak.

Reverse Osmosis: Reverse Osmosis is one of the most common and widely used technology used in water purifiers today. In a reverse osmosis water purifier, water is forced through a semi-permeable membrane so that only water molecules will pass through, trapping sediments and contaminants on the other side of the membrane.

Ultra Violet: In water purifiers with ultra violet technology, UV bulbs emit ultraviolet radiation that is capable of killing harmful and disease-causing bacteria in the water. This system alone only kills the bacteria but their bodies remain in the water.

No one filtration technique is 100% capable of purifying your water and making it completely safe for drinking. Many manufacturers realize this so it is not strange to find a water purifier with a combination of two or more filtration techniques in one unit. The ideal combination is the reverse osmosis and the UV purification system as explained on bestwaterpurifierinindia.in. The UV radiation will kill the bacteria and the semipermeable membrane of the reverse osmosis system will filter out the bodies of the dead bacteria out of the water.

How to Use a Cordless Impact Driver

A cordless impact driver is a very flexible tool that can be used to turn screws and drill holes. This tool accepts a multitude of circular and hexagonal shank drill bits that is compatible with so many extensions and accessories. Cordless impact drivers also have slide clutch that allows the user to adjust the amount of torque being sent to the bit to allow for precise screw driving and drilling.

Cordless impact drivers use driver rotation and concussive blows to push screws through tough materials. Impact drivers can deliver up to 2-3X more torque than an average driver. Despite all the power this tool generates, it is incredibly comfortable and easy to use because all the torque is transferred to the screw not the hand wielding the tool.

It is essential to know how to utilize a cordless impact driver to achieve wonderful results and to keep the tool in good condition while staying safe. It is advised to wear gloves to protect your hands, hammer safety glasses to protect your eyes and ear muffs to protect your ears when using a cordless impact driver. After all these safety gears have been worn, proceed with fitting the proper socket or adapter on the tool.

When you begin working on the screw, remember that generally, the clockwise direction is for loosening screws while tightening is done in the anticlockwise direction.

Before you Start Working

  • Make sure the site is safe and meets the conditions stated in the precautions.
  • Ensure the battery is well installed. If not firmly installed, it may fall off when the tool is in use and cause an accident.
  • Install the correct bits. This is usually done by pulling the manual sleeve, putting the bit in the hexagonal hole in the anvil and then releasing the sleeve.
  • Check the rotation direction. Switch to clockwise or anticlockwise depending on your preferences for that particular work.
  • If your cordless impact driver comes with a user’s manual, it is best to go through this manual, understanding everything therein before using your tool. Follow all the instructions in the manual and adhere to all warnings. These are for the safety of the user and the tool itself.

Proper Foot Care: Optimize your Nursing Shoe

Proper foot care is important for everybody but most especially for people who spend about 8-16 hours of the day on their feet, for example Nurses. Wearing the right shoes is not all there is to maintain a pain-free and healthy work shift. How you maintain your nursing shoe and the feet that wears it matters a lot.

For medical practitioners especially nurses, proper foot care is a necessity. A few minutes of monitoring the condition of your feet goes a long way in ensuring healthy feet throughout those long shifts.

  • The best shoes for nurses can provide you with comfort and support but that is not all there is to achieving a healthy foot. Many infections on the foot are caused by poor circulation. Also, untreated sores can lead to infections so carefully inspecting your feet for sores and blisters every day is a worthwhile practice. Do not ignore blisters, red spots and discoloration as these are early signs of a sore waiting to happen.
  • Wash your feet on a daily basis, paying special attention to the toes and in-between the toes because these spots tend to encourage growth of bacteria and fungus. Some people usually in a hurry do not dry their wet feet before putting on socks and slipping them into their shoes. This must be avoided! Dry your feet properly after washing before wearing your socks and subsequently your nursing shoes.
  • Trim your toenails regularly, do not let them overgrow. Overgrown toenails can lead to injuries and cause your nursing shoes to feel as though they don’t fit; causing discomfort on an already stressful job. The best time to do this is immediately after a shower because the nails are soft at this time and easier to cut. Use scissors or cutters designed for trimming fingernails. Desist from using every sharp object you find for this task. Trimming your toenails also affords you the opportunity to inspect your feet properly.
  • Always wear fresh, clean and comfortable socks with your nursing shoes. These must not be too tight nor too loose; get socks with a comfortable fitting.
  • Examine your nursing shoes regularly for signs of uneven wear. This indicates that there are pressure points on your feet.
  • Opt for quality leather shoes because they breathe better and allow your feet access to some air; also they adapt the shape of your feet better than other materials.

Proper foot care will make sure you get the most out of your favorite pair of nursing shoes.
