The future is always beyond common sense
Conducting research and development without a precedent. When striving to create something unprecedented, internal resolution became a necessity. FILTOM is a development-oriented research lab that manages everything from raw materials to finished products. We take pride in our unparalleled development speed and operate as a hybrid lab with a vast network of external partners across various fields. We aspire to continually redefine the conventional wisdom of chemistry.
The First PD Membrane Separation Method in the World
Our unique PD membrane separation method represents the most pioneering filtration technology in the world. PD stands for Pore Diffusion, whish is ideal for extracting high-concentration, high-viscosity liquids such as blood and placenta. The PD membrane separation method can filter down to nano-sized level. It is inspired by a combination of dialysis techniques employed in artificial kidney dialysis and filtration methods used in water treatment. This innovative approach, which takes cues from the human circulatory system, has been patented, opening to the development of a revolutionary separation technology. For the first time, it enables the creation of fully unheated active placenta products, preserving their precious components in their natural state and challenging traditional filtration norms.
Unlike traditional dead-end membrane separation, which passes liquid perpendicularly through the membrane, PD membrane separation allows liquid to flow parallel to the membrane, slowly passing through it. This mimics the nutrient absorption mechanism in the kidneys and blood vessels. FILTOM has conducted precise research on these conditions, making it the first in the world to achieve placenta membrane separation, which was impossible with conventional dead-end membrane separation. Traditional membrane separation methods (dead-end filtration, which filters perpendicularly to the membrane) struggle with high-concentration, high-viscosity liquids containing many particles and fibers, as they quickly clog and become difficult to separate. This necessitates heat treatment, chemical treatment, or radiation treatment, which can degrade the active components.
In the PD membrane separation method, the raw liquid flows parallel to the membrane surface at a consistent flow rate, maintaining the differential pressure across the membrane at a low range of 0.02-0.05 atmospheres. This condition is close to those in the kidneys, allowing nutrients to pass through the membrane pores (18 nanometers) by diffusion. This mechanism enables the separation of nutrients from viruses (approximately 25 nanometers) and bacteria. By appropriately setting the membrane pore size, flow rate, and filtration pressure, long-term filtration without clogging, like kidney function, can be achieved. Additionally, the material and surface modification of the membrane can be varied to change separation performance, mirroring the kidney’s adaptability. Using these features, FILTOM continues to develop towards future seawater desalination.
