The Ultimate FAQ Guide for Portable Water Filtration Systems.

Virtually all human activities revolve around freshwater, which is naturally available in scarce amounts. To gratify the universal demand for potable water, homes, industries, and commercial enterprises with limited or no access to fresh water has resorted to unorthodox water sources like groundwater and seawater. These water sources are largely contaminated and their exploitation necessitates sufficient treatment.

Beneath, we take a special look at portable water filtration systems and their role in tackling water scarcity.

➣What is a Portable Water Filtration System?

A portable water filtration system is a mobile water treatment system utilized to filter out undesired constituents from water. In essence, they are typical water filtration systems specifically designed to facilitate movability. They eliminate impurities using chemical, physical or biological processes.  Contemporary water filtration systems employ well-regarded technologies such as membrane filtration, ion exchange, and media filtration thereby producing high-quality filtered water.

They can be utilized differently; as standalone systems, as pretreatment systems, or as post-treatment systems. Similarly, they can be deployed in residential, commercial, and industrial water treatment. Primarily, portable water filtration units are utilized to selectively eradicate specific pollutants hence they can be used to treat different forms of feed water.

➣Which Processes Are Used in Portable Water Filtration Systems?

Portable water filtration systems generally eliminate pollutants from water using chemical, biological or physical processes. In fact, the majority of portable water filtration systems are named after the process they employ to filter out impurities. Underneath are the most utilized water filtration technologies in water filtration systems.

● Membrane filtration.

Membrane filtration essentially employs partially permeable membranes as the primary filtration media or barrier. The popular membrane filtration process is unquestionably reverse osmosis, which primarily eradicates dissolved solids as well as other objectionable elements. It is essentially driven by pressure and can eradicate 95-99.7% of dissolved salts. Similarly, ultrafiltration utilizes membranes and pressure to alienate impurities. However, it is a process more suited to eliminating suspended solids because of its pore size (0.01 microns).

Moreover, nanofiltration tech can be deployed to remove most viruses, organic matter, and substantial amounts of dissolved solids. A nanofiltration membrane customarily measures 0.001 microns while a microfiltration membrane has perforations measuring approximately 0.1 microns. Here is a video explanation to help you understand membrane filtration.

●  Media filtration.

Media filtration utilizes a layer of media or multiple media layers to separate undesirable contaminants from water. The primary media filtration processes commonly exploited are:

● Multimedia filtration.

Multimedia filtration deploys multiple media layers (three or more) to eliminate suspended solids from water. The layers commonly utilized media layers are anthracite, sand, and garnet. Ideally, multimedia filtration shrinks the concentration of particulates to 10-25 microns.

● Pressure sand filtration.

Pressure sand filtration utilizes a single media layer to filter out the undissolved matter, and suspended elements and to reduce turbidity. The layer of media employed is ordinary sand, which is characteristically configured according to size and gravity. The suspended solids are decreased to 25-50 microns. This animation further illustrates the process of pressure sand filtration.

● Carbon filtration.

In carbon filtration, activated carbon granules or blocks are deployed as the filtration media. This process eradicates organic chemicals, chlorine, and volatile organic compounds (VOCs) using the process of adsorption.

● Ion exchange filtration.

Ion exchange filtration utilizes ion exchange resins (cationic and anionic) to substitute ionic pollutants from water with desirable ions. This process is commonly used to soften hard water and deionize water. The cationic exchange resins release hydrogen (H+) or sodium (Na+) ions while the anionic exchange resin releases hydroxyl (OH-) ions.

➣What Are the Advantages of Portable Water Filtration Systems?

Portable water filtration systems share similar benefits with conventional water filtration systems. However, their portable designs make them a little bit more advantageous. They are easy to transport and can be conveniently utilized in permanent and temporary applications. Beneath are some of the most impactful rewards you will gain from exploiting portable water filtration systems.

• Reverse osmosis filtration systems eradicate 95-99.7% of Total dissolved solids (TDS) as well as other impurities like viruses, minerals, and bacteria.
• Media filtration systems are highly effective in removing suspended solids and can lower their presence to 10-25 microns.
• Activated carbon filters eliminate organic chemicals, which typically give water a nasty taste or odor.

● Portable media filtration systems.

Portable media filtration systems are generally water filters that are reliant on a media layer or multiple layers of different media to alienate pollutants from water. Media filtration systems are commonly exploited to eliminate chemical, physical, and biological impurities.

Pressure sand filters and multimedia filters are generally utilized to eliminate suspended solids and sediments. Carbon filters on the other hand are commonly deployed to remove VOCs, chlorine, and organic chemicals. Portable media filtration systems are largely utilized in pretreatment but can be used as standalone water treatment solutions.

● Portable membrane filtration systems.

Membrane filtration systems are considerably more effective than conventional media filters. They utilize semipermeable membranes to trap and alienate unwanted pollutants. Portable reverse osmosis systems are the most effective and popularly utilized membrane filtration systems. The other membrane filtration systems regularly exploited are:

• Ultrafiltration water systems.
• Nanofiltration water systems.
• Microfiltration water systems.

● Portable ion exchange water filters.

Portable ion exchange water filters are water treatment systems that filter out ionized pollutants using ion exchange resins. They are chiefly used to soften water, treat wastewater, and deionized water. Ion exchange water systems are further classified as either:

• Dual-bed ion exchange systems.
• Mixed-bed ion exchange systems.

● UV water sterilizers.

These are special filtration systems often employed to inactivate viruses, bacteria, and other disease-causing microorganisms found in raw water. UV water sterilizers are often employed as post-treatment systems to kill the microbes that survived the primary filtration process.

➣Which Sources of Water Can Be Treated Using Portable Water Filtration Systems?

The development of distinct water filtration systems and mechanisms has essentially broadened their application fields. At present, there is virtually a water filtration system customized to treat feed water from every accessible source. There are specialized seawater filtration systems, well water filtration systems,  tap water filtration systems and brackish water filtration plants.

In addition, there are advanced portable water filtration systems for treating hard water i.e. cation ion exchange water filters. However, using a single water filtration system to treat certain types of feed water may not get rid of all contaminants. Therein, multiple filtration systems such as media filters and RO membrane filters can be interlinked for higher output.

➣How Do You Clean Portable Water Filtration Systems?

As your portable water filtration system helps you clean your feed water, it inadvertently collects some of the objectionable elements. To continue reaping the optimum rewards, cleaning is needed to flush out the amassed pollutants. Periodically cleaning your portable water filtration system minimizes how frequently you need to replace the system by prolonging its lifespan.

Water filters are generally cleaned using the backwash process. Essentially, water is forced through the media layer in reverse (from the bottom upwards). Backwashing can be initiated manually or automatically whereby automatic cleansing is commenced after a specified timeline or after a certain quantity of water has been filtered. Here is how you backwash a water filter.

Membrane filtration systems are easier to clean thanks to membrane cleaning systems, which you can acquire from NEWater. Ion exchange filters are cleaned using the backwash process and after they are recharged using a regeneration chemical. Cationic exchange filters are regenerated using acids like hydrochloric acid while anionic exchange filters are regenerated using base regenerates such as lime.

➣What Are Activated Carbon Filters Used for?

Through adsorption, activated carbon filters eliminate Volatile Organic Compounds (VOCs), herbicides, chlorine, pesticides, and unpleasant smells and tastes. They are media filters that essentially utilize granularly or block carbon as the filtration media. Their application in water filtration is mainly as supplemental systems. Activated carbon filters are typically used as pretreatment systems or post-treatment units.

When filtering drinking water, activated carbon filters are specifically exploited to eradicate the organic chemicals, which often give the water a bad smell or taste. Their deployment as pretreatment systems helps regulate the acidity of the feed water thereby averting corrosion of vital equipment. Moreover, they are quite handy as wastewater treatment systems where they eradicate the volatile chemicals present in wastewater.

➣How is Reverse Osmosis Used in Portable Water Filtration Systems?

Reverse osmosis is a leading water treatment technology that exploits RO membrane filters to alienate contaminants from water. Essentially, pressure is applied to the feed water using a pressure booster pump. This prompts water to flow from streams with a higher concentration to the lowly concentrated stream, unlike typical osmosis. A barrier of semipermeable membranes separates the foreign constituents from the water. The pores in the RO membrane are so microscopic that only water molecules and low-molecular-weight elements are allowed passage.

Dissolved solids, which include dissolved salts, proteins, bacteria, viruses, and minerals are blocked off. They remain on the retentate stream while the water on the other side (the permeate stream) is harvested as filtered water. The water collected may be suitable for immediate use depending on the application. If not, it is refined using supplemental systems such as electrodeionization units and activated carbon filters.

➣Which Post-Treatment Systems Are Used in Portable Water Filtration Systems?

When in need of highly purified water, you might need to supplement your water filtration system with a polishing system. This is because most if not all water filtration systems are incapable of single-handedly eradicating all waterborne contaminants. Here is a brief elaboration of the post-treatment systems you can exploit to improve the efficiency of your portable water filtration plant.

● UV water sterilization.

Conventional water filtration systems such as media filtration systems and membrane filtration units often fail to fully remove microbial pollutants from water. UV water disinfectants on the other hand are mainly equipped to eliminate virtually all microbial impurities. They generally remove 99.99% of viruses, fungi, bacteria, and other illness-causing microorganisms by destroying their DNA cells.

● Electrodeionization water systems.

These are systems capable of generating high-purity water for sophisticated applications such as laboratory uses and pharmaceutical manufacturing. EDI water systems, in the modern world, are chiefly used to polish water cleaned using conventional water deionizer systems and reverse osmosis systems. They are powered by a direct current, hardly utilize chemicals, and are easy to operate. Ideally, they remove all ionic contaminants using ion exchange resins and membranes.

● Reverse osmosis systems.

Reverse osmosis systems are frequently exploited to refine the water filtered by media filtration systems e.g. multimedia filters as well as the permeate from other membrane filtration systems. RO membranes have perforations significantly smaller than ultrafiltration, nanofiltration, and microfiltration membranes hence they can eradicate finer pollutants. Additionally, reverse osmosis machines can remove microorganisms and dissolved solids.
