Water Filtration

Water filtration uses either biological processes, chemicals, or a physical barrier to remove contaminants from the water. This improves the taste, color, and purity of the water. Water filtration focuses on impurities such as bacteria or larger particles. Unfortunately, filtration methods don&#;t always remove other contaminants, such as chemicals or viruses, that may be present in water.

Water Purification

Water purification works to further purify water from contaminants that filtration methods can&#;t address. It removes the chemicals, viruses, and biological contaminants that filters don&#;t and uses a chemical process rather than typical barrier or boiling methods used for water filtration. Water purification removes the minerals in water also, which filtration doesn&#;t typically do.

Water Filtration Methods

There are portable water filters that can be used to filter unteated water from streams and lakes or filter pitchers that you keep in the refrigerator. There are numerous systems used in a home to treat the water from certain faucets or to treat all the water in the house. Drinking filters are installed at the kitchen sink and the filter is stored underneath the sink. A separate tap is used for the filtered water. Shower filters help remove chlorine and chemicals that cause excessive drying and damage. Whole house filters are connected to the home&#;s main water supply to remove sediment and contaminants. Most of these filters use activated carbon to create an ion exchange process to remove these contaminants.

Water Purification Methods

Reverse osmosis is the most popular type of water purification method. Rather than using a carbon filter to catch the contaminants, it forces all the water through a semipermeable membrane. This screens out particles that a carbon filter doesn&#;t catch. Deionization is another form of water purification in which all the charged particles are removed. Distilled water requires water to be boiled, and the condensed steam is collected. These water purification methods aren&#;t typically used in homes; they&#;re most often used in labs, biotech and pharmaceutical industries, or for manufacturing processes.

Things to Consider

The best way to decide whether water filtration or purification is best is to know what&#;s in your water. A water testing lab can test for a range of contaminants in your water and give you a report showing the levels of these contaminants. An important thing to consider in addition to which impurities you need removed from your water is the impact of removing the minerals from your water. Water purifiers remove all the minerals from your water, and while this can be good if you have hard water problems, there can be health effects as well. Minerals such as calcium, magnesium, potassium, iron, and others are important to the body, so water should have a minimum level of these essential minerals. Water filtration will keep these minerals in your water, but if you choose water purification methods, you&#;ll need to either be vigilant about consuming foods with these minerals or get a purifier that has a remineralizer.

The laboratory water purifier is one of the most important elements of any lab. Its main purpose is to supply lab water or pure water to the various lab applications.  These lab applications can be:

• Simple Chemicals Experiments
• Biopharmaceuticals Products
• Biosafety Lab Experiments
• Complex Research Work.

All these applications require pure water in ample amounts to execute. And this pure water is obtained through a lab water purification system installed in a lab.  There is no doubt that lab water is called the &#;hero&#; of any lab.  Without the usage of lab water, you don&#;t get perfect and reliable results and the whole of your experiments gets faulted. In any case, you don&#;t want that malfunction to occur to you.  For that, you install a water purification system for the laboratory to obtain pure water.  Before buying any of the lab water purifiers, do extensive research on them to get a perfect lab water system.  The market is full of all kinds of lab water purifiers with different water purification technologies.  But the thing is you have to purchase the one which fulfills your lab needs. There are various parameters for choosing an ideal water purification system for your lab.  However, before embarking on the journey to find a suitable water purification system for laboratory use, you should know how pure water impacts your lab applications and experiments.

Pure Water In Lab

Laboratories are full of experiments that are performed daily by researchers and scientists. They carry out all experiments with pure water to get good results. You may be wondering what pure water does, which makes it a favorite of the lab fellows. For this, it is said that pure water has the highest purity of all types of lab water. There is no impurity present in the pure water,  which can alter the experiment results. 

The mere absence of any kind of impurities makes pure water more reliable and good. It is seen that normal tap water has many impurities in the form of inorganic solutes, organic compounds, nucleases, other related biomolecules, etc.  All these impurities or contaminants have the capacity to interfere with the analytical experiments, and thus,  produce bad results. It is often seen that researchers sometimes use the normal water for experiments which is not a good practice at all.  For every type of lab application,  the use of pure water should be done.  In a lab, the purity of pure water should not be compromised in any case. Any negligence can produce bad results that would be the wastage of your resources and experiments.

The market has all types of water purifiers stacked with their own water purification technologies. These technologies range from simple purification methods to advanced ones. You may feel baffled by such kinds of water purifiers. To tackle this, you can go for the following steps before purchasing the one ideal water purification system for laboratory use.

1.Know The Type Of Pure Water You Need For Your Research

There is no doubt that any kind of research in the lab requires water.  However, every type of water has its own significance and use.  For example, type I water is used in various analytical experiments like HPLC, gas chromatography, etc. For this purpose, only type I water can be used. No other pure water types should be used with all these experiments. So, it is said to determine the type of water you need for your laboratory.  Many water purifiers do produce type I as well as other types of water, while some purifiers only produce type I.  Make sure the type of water you need for the experiment.

To determine the type of pure water you can go through the usages of different types of lab water. This would help you know more about the applications of pure water and you can easily determine the type of water you need for your experiments. 

2.  Do Know The Contaminants Of Feed Water Fed Into The Water Purifiers

The normal tap water is full of total organic content which is not good for lab experiments. These impurities can alter the experiment results and thus produce bad results. In a lab water system,  you can regulate the quality of feed water fed into it.  This process is called as pre-treatment of water.  Some water purifiers purify the water, to great extent, but some do not.  In this case, you have to check the contaminants of the water before installing a lab water system.

Further, some lab water purifiers only eliminate the dissolved gas ions from the feed water. In this case, you may not get complete purified water for your lab experiments.  In some cases, the lab water contaminants are tested to determine the water purification technology for the lab water purification system. 

3.Know The Water Purification Technology Used In A Lab Water System

With a lab water purification system comes the water purification technologies which are well fitted into the system. These technologies can be :

• Activated Carbon Technology
• Ion-Exchange method
• UV-Radiation Method
• Advanced Distillation Method

The above technologies are effective in treating feed water to produce pure water. Most of the time, people install a lab water purification system without knowing the technology. This would cost the researcher very much. As different types of water are produced by different water purification technologies. After the determination of the type of water you need for the lab experiment, the next step is to know about the purification technology.  How does it work? What is the purification rate? etc. Go through the whole guide for water purification technology. There are many water purification systems in the market that can be analyzed for your experiments.  You may also check any water purification system for laboratory price in online and offline mode. 

Following is the brief of water purification technologies and their purified pure water type:

• Activated Carbon Method: Type II and III
• Ion-Exchange Method: Type III
• UV -Radiation Method: Type I 

4.Know The Amount Of Pure Water You Need For The Lab Experiments

This is the simplest of the above factors in settling with a lab water system. You have to make a quick list of the amount of pure water you need for your experiments. In some lab water purifiers, the supply of pure water is less, while some have a good capacity for water supply.  In other cases,  it is seen that the simple experiments take about less pure water intake than the complex ones. 

In both the above cases, you need to check your pure water amounts.  This would help in settling a good lab water system for your laboratory.  This would also ensure that you don&#;t be at any loss of pure water in the experiment.

5.Know How The Pure Water Will Impact Your Research or Laboratory Work

There is no doubt that pure water has an impact on laboratory experiments.  The quality of pure water has a direct effect on the sequence of events in a lab. Water purification system for laboratory use has the purpose of producing pure water in a continuous way. The water should be pure enough to have a positive impact on the lab work. As a researcher, know how the water is going to impact your lab work.  Some cases, the impurities can also be helpful, but in most cases, it is not regarded as good. Take care of this before going forward to settle a water purification system for the laboratory.
