3. Reverse Osmosis Systems

Reverse Osmosis (RO) systems use semipermeable membranes to remove dissolved contaminants like minerals and salts from water. RO systems apply pressure to the water to separate impurities, ensuring your water is purified.

Reserve Osmosis systems are among the most popular water filtration systems in residential and commercial settings. They effectively remove many contaminants, including heavy metals, fluoride, nitrates, and microorganisms. RO systems ensure high-quality pure water for drinking, cooking, and other applications that require water purity.

RO systems have several essential components, such as a pre-filter, membrane, storage tank, and post-filter. The pre-filter protects the membrane by removing sediments and larger particles. The membrane, being the core component, separates contaminants from water, while the storage tank holds a ready supply of purified water.

4. UV Water Purifying Systems

UV water purifiers disinfect water using ultraviolet (UV) light to inactivate microorganisms like bacteria and viruses. The UV light destroys the organisms’ genetic material, making them unable to multiply and cause harm.

They are used primarily in residential, commercial, and municipal water filtration systems to provide additional protection against harmful microorganisms and ensure drinking water is safe and healthy. UV purification is chemical-free, eco-friendly, and does not change the water’s smell or taste.

UV water purifiers contain a UV lamp in a protective chamber through which the water flows. The water gets exposed to intense UV light as it passes around the UV lamp, thus neutralizing viruses, bacteria, and other harmful pathogens. The purifying system requires periodic lam replacement to maintain optimal performance.

5. Ion Exchange Systems

Ion exchange systems exchange ions between water and a resin medium. It is meant to remove undesirable ions like magnesium, calcium, and heavy metals, replacing them with more desirable ions such as potassium or sodium.

Ion exchange systems are used widely to soften water, remove hardness-causing minerals, and prevent scale buildup in plumbing systems and appliances. They also eliminate heavy metals, making water safe and better tasting. They are used primarily for residential and commercial applications.

This system can be used in various industries, such as water treatment, pharmaceuticals, food and beverage, and power generation. They remove specific ions and contaminants tailored to the requirement of each sector. The resins can be regenerated, thus expanding the system’s lifespan.

6. Ultrafiltration Systems

Ultrafiltration (UF) systems use membranes with tiny pores to physically segment particles and microorganisms from water. The pores in UF membranes are smaller than sediment filters but larger than those employed in reverse osmosis systems.

Ultrafiltration systems are widely used to remove bacteria, viruses, turbidity, and suspended solids, delivering clean and clear water in residential, commercial, and industrial settings. They find applications in wastewater treatment, water purification, and the food and beverage industry.

Ultrafiltration provides an excellent balance between filtration and system complexity compared to other filtration systems. It is a cost-effective solution for removing many contaminants, ensuring it is suited for diverse applications. This system does not require electricity and is relatively easy to maintain.
