Water Purification: Solution to Modern-Day and Future Water Scarcity.

Over the past few decades, a variety of remedies have been attempted to alleviate chronic and severe freshwater shortages. Water purification has proven to be the most feasible.

Currently, millions of homes, industries, and commercial businesses rely on water purification equipment. This number continues to grow significantly as the cost of purchasing and operating equipment decreases. So what are the benefits of water purification?

Reverse Osmosis In Laboratory Water Purification Systems

1. Water Purification Technologies

With more people having to rely on water purification systems, innovators are continually advancing existing purification technologies. Presently, there are over 10 well-renowned water purification mechanisms helping billions of people fight freshwater undersupply. Here is a brief description of today’s most effective and efficient water purification technologies.

  • Pre-treatment

Pretreatment provides protection for RO membranes and other subsequent purification technologies, and is typically used in the final step of the water purification process.

The process utilizes a deep filter as a pretreatment. Tap water is passed through a wound or meltblown filter cartridge and activated carbon to capture and adsorb impurities.

  • Reverse Osmosis Water Purification.

Reverse osmosis is without a doubt one of the most prominent and effective water purification technologies at present. It is a dynamic process that extracts a myriad of distinct pollutants at exceptional rates. It is defined as a power-dependent purification process that forces the alienation of objectionable impurities from water using pressure and partially porous membranes.

Pressure is pivotal in reverse osmosis and it is applied to the feed water. This overpowers the natural osmotic pressure subsequently reversing the flow of water. Impurities denied passage by the semi-permeable membranes are left as a residue referred to as brine while purified water is collected as permeate.

  • Deionization.

Deionization is a distinct and highly effective water purification process that extracts undesirable ions by replacing them with non-objectionable ions. Deionization water purification systems utilize ion exchange technology to eliminate objectionable mineral ions. This technology is commonly used in water softening, demineralization, and de-alkalization. Deionization can be accomplished using either;

(1)Mixed-bed deionizers.

(2)Two-bed deionizers.

  • Ion Exchange

The process uses ion exchange resins to remove various unwanted ions from the water. As water passes through the ion exchange resin, anions and cations in the water react with ions on the resin. All ions are replaced by hydrogen and hydroxyl ions, which recombine to form pure water, thus achieving the removal of soluble salts from the water.

  • Electrodeionization.

Electrodeionization is a complex and high-yielding water purification process that applies direct current to eradicate ionized impurities using ion exchange resins and membranes. Regeneration in EDI water purification systems is power-driven and does not necessitate the use of chemicals. This makes it environmentally friendly and relatively cheaper. Electrodeionization can generate high-purity water with a resistivity of 18.3 Megaohms.

  • Ultraviolet (UV)

Ultraviolet (UV) light photo-oxidizes at 254nm and 185nm wavelengths respectively. Photo-oxidation and UV elimination of trace organics can inactivate microorganisms in the source water. 254nm UV reacts with bacterial DNA, causing denaturation, while 185nm UV breaks down long-chain organics, which are then removed from the water by ion exchange.

  • Ultrafiltration (UF)

Ultrafiltration is used to remove pyrogens (bacterial endotoxins) and ribonucleic acid. This process is critical when preparing water for tissue or cell culture. Ultrafilters remove molecular substances according to their molecular weight. Ultrafilters are typically used at the end of a water purification system to ensure that large molecule impurities such as pyrogens, RNA and particulate matter are completely removed before the water is used.

2. Advantages of Water Purification.

Principally, water purification systems offer fresh, uncontaminated water, which is requisite for human life, business operations, and industrial processes. Since their inception, water purifiers have gone from strength to strength, with contemporary purifiers being high-yielding, cost-efficient, and easy to use. Beneath, we look at the varying rewards offered by modern-day water purification equipment.

  High-quality Purified Water.

Fresh water is one of the world’s most treasurable resources and without it, life on earth would be untenable. Given that at least 2 billion people spread out across the world reside in regions with stark freshwater insufficiency, the value of water purification equipment cannot be understated.

Purified water systems provide an efficient and effective way of converting 70% of dirty and polluted water reserved in oceans and underground reservoirs into tenable fresh water. They eliminate objectionable constituents such as dissolved salts, viruses, and bacteria consequently generating purified water fit for human consumption, industrial use, and commercial use.

  Dynamism in Impurity Removal.

According to the WHO, an estimated 2.4 billion people draw their daily usage of water from contaminated sources. These sources could be the oceans, lakes, rivers, boreholes, or even taps and harbored pollutants may include illness-causing microbes, hardness minerals, dissolved salts, and volatile chemicals.

The repercussions of waterborne pollutants spread beyond stark health conditions. Hardness-causing minerals, for instance, may cause corrosion, spotting, and destruction of domestic appliances. However, with a reliable water purifier, these aggressive and dangerous impurities are eradicated before they can cause any harm.

  Environmental Conservation.

Water purification systems help conserve the environment in a number of ways. First, wastewater treatment systems, get rid of volatile pollutants from wastewater before it is discarded in landfills or nearby waterbodies. The effluent emitted by wastewater treatment systems meets the existing effluent quality threshold and does not pose a threat to the surrounding ecosystem and its inherent inhabitants.

Secondly, water purifiers help preserve natural freshwater reservoirs by providing alternative sources of pure water. This reduces the stress placed on natural water resources thereby averting overexploitation.

Thirdly, solar water purifiers play a pivotal role in combating adverse climate change. They utilize a renewable and eco-friendly source of energy_the sun, as opposed to fossil fuels, which emit greenhouse gases responsible for global warming.

Impeccable Purification Rates.

Ultra-modern water purification systems are extremely effective in eradicating the respective impurities they are designed to eradicate. They are primarily manufactured to eliminate specific impurities and they do exactly that at an impeccable rate. Seawater purification systems such as reverse osmosis desalination units eliminate 90-99.7% of dissolved salts to generate fresh water with a maximum TDS score of 1000ppm.

Typical UV water sterilizers destroy 99.99% of viruses, bacteria, and other microbial pollutants using ultraviolet radiation. However, impeccable purification rates are only attainable when the purifier is deployed appropriately and serviced regularly.

3. Why is Water Purification Important?

Water purification equipment is vital in everyday life and in the bottled water industry. Purified, healthy water removes all potentially harmful metal ions, viruses, bacteria, and organics from the water, making it suitable for drinking and tasting good.

For commercial applications such as hotels, restaurants, and car washes, good water quality is a sign of high-quality service. It enhances the customer experience and satisfaction level, which in turn leads to a good reputation and goodwill.

The purity of the water is critical to the accuracy and reproducibility of the quality results of the reagents configured. Therefore, the success of a scientific study or clinical experiment depends on the quality, suitability, and reliability of the purified water supply.

4. Can I Drink Water Purified Water?

Pure water generally refers to water that has been treated by an ultrapure water instrument. The TDS value of distilled water prepared by reverse osmosis, distillation, ion exchange, and other methods is usually <5PPM and the conductivity is usually <10us/cm. Pure water has most impurities removed and contains no minerals.

Generally speaking, the pure water in the laboratory is drinkable, but drinking it directly is not recommended. Pure water comes from many sources, such as tap water, surface water, groundwater, etc. If surface water or groundwater is used as the source, the pure water prepared may contain bacteria and some organic matter. Drinking it directly may cause diarrhea and other physical conditions.

6. Emerging Trends in Water Purification Technologies and Water Purification Machine.

We presently live in a world driven by constant innovations and water purification technologies are no different. Technological breakthroughs continue to be made and this brings about a number of rewards. For instance, recent strides made in energy recovery technologies have rewarded us with more power-efficient water purification equipment. Here are some of the additional emerging trends making water purification more affordable, effective, and efficient.

• More Compact Purification Equipment.

Astronomical prices for properties and population growth are limiting the spaces people have to live in or run businesses. This means that there are no spare storage spaces for essential appliances. However, proactive manufacturers of water purification systems such as NEWater, are developing small-sized purifiers that are more economical on space. These units are also easy to transport, install, and operate.

• Re-mineralization.

Certain purification technologies such as demineralization and reverse osmosis, eliminate vital minerals from drinking water. Consumption of demineralized water does not have immediate health implications but over time one may develop dietary deficiency disorders.

To avert this, drinking water purification processes have been tweaked a little bit to accommodate the re-mineralization process. This post-treatment process simply adds back essential minerals such as magnesium and calcium to deliver safe and healthy drinking water.

• High Demand for UV Water Sterilization Equipment.

The World Health Organization reports that one in three people have no access to clean drinking water and that over 3.4 billion lives are lost to waterborne illnesses. To curb the transmission of these diseases and avert consequential causalities, most households are now installing UV water sterilizers.

Commercial enterprises, municipalities, and industries reliant on purified water are also ditching chlorination for UV water sterilizers. This is chiefly because the systems are now cheaper, more effective, and hardly alter the water’s taste/odor.

• Automatic Water Quality Monitors.

Present-day water purification systems are fitted with high-quality monitors that display real-time data regarding the purified water. These monitors display definitive parameters that depict the quality of water, for example, the water’s conductivity, resistivity, and microbial count.

In addition, these automatic screens monitor water levels and daily consumption rates. For users, this saves time and makes their user experience stress-free. In the near future, it is expected that there will be more advanced water purifiers capable of monitoring even more parameters.
