Ultrafiltration Machine
An ultrafiltration machine is a water purification system that uses advanced ultrafiltration technology to clean water. This process relies on a special ultrafiltration membrane, which acts as a highly efficient filter that separates water molecules from impurities. The filtration precision of such machines can be extremely fine—often around 0.00001mm, making them very effective at removing contaminants like bacteria, viruses, and large organic molecules. For example, the Helos ultrafiltration machine is known for its high-performance filtration capabilities.
Ultrafiltration machines come in two main types: straight drinking water units and water purifiers. Straight drinking water models are designed for direct consumption, while water purifiers are typically used in kitchens to provide clean water for cooking or other household purposes. Water purifiers often combine stainless steel or ceramic shells with ultrafiltration membranes, offering high flow rates and the ability to remove harmful substances like sediment, rust, algae, and large organic compounds, while preserving beneficial minerals that the body needs.
On the other hand, straight drinking ultrafiltration machines usually include multiple stages such as PP filters, activated carbon, KDF, and the ultrafiltration membrane itself. This multi-stage filtration ensures a thorough cleaning process, effectively removing harmful particles, bacteria, and residual chlorine from the water.
Despite their effectiveness, ultrafiltration machines may not be suitable for all homes. In areas where water quality is extremely poor, it's recommended to use a more advanced purification system like a reverse osmosis unit.
Reverse Osmosis (RO) Water Purifier
A reverse osmosis water purifier is one of the most advanced water treatment systems available today. It uses the reverse osmosis principle to remove impurities from raw water, producing clean, safe, and high-quality drinking water. These devices are widely used in households, hotels, hospitals, and other commercial settings due to their reliability, ease of use, and compact design.
How it works:
Stage 1: A PP fiber filter removes large particles like sediment, rust, and suspended solids, protecting the RO membrane from damage.
Stage 2: A granular activated carbon filter helps eliminate odors, colors, and harmful chemicals such as chlorine, pesticides, and carcinogens.
Stage 3: Another PP fiber filter provides an extra layer of protection, ensuring the RO membrane remains in good condition.
Stage 4: A high-tech RO membrane with pores as small as one-tenth of a micron effectively removes bacteria, viruses, heavy metals, and chemical residues.
Stage 5: A coconut shell activated carbon filter adjusts the taste of the purified water, removing any remaining odors and adding a small amount of beneficial minerals for a sweeter, more pleasant drinking experience.
While reverse osmosis systems are highly effective at removing all types of impurities, they also strip the water of essential minerals and produce a certain amount of wastewater during the process.
Tips for Choosing Between Ultrafiltration and RO Systems
Both ultrafiltration and reverse osmosis machines offer excellent water purification results, but the best choice depends on your local water quality. Ultrafiltration systems are ideal for areas with relatively clean water, while reverse osmosis is the safer option in regions with severely polluted water sources.
