1. Sediment filter
Sediment filters remove visible particulate matter, and any particles of dirt, sand, dust.
Sediment filters also remove turbidity from water. Turbidity is the cloudiness caused in water by the heavy presence of suspended solids. This causes water to turn yellow, orange, or brown.
All ranges of our products are using the sediment filter having a pour size of 10 microns for excellent filtration and that helps to increase the life of RO and UF membranes.
2. Activated Carbon Filter
An activated carbon filter has remarkable taste, odor, and chlorine reduction capabilities. Water treatment plants treat water with chlorine and chloramines that create cancer-causing by-products.
Carbon clears the water of organic compounds that make your water taste or smell bad.
Carbon filters remove contaminants through adsorption. Absorption soaks up particles like a sponge to water. Organic compounds bond or stick to the surface of a carbon filter because water and contaminants are both polar compounds that attract one another.
Carbon filters are extremely porous and have a large surface area, making them effective at reducing bad tastes, odors, and other particles in water. A carbon filter acts as a parking lot with pores for parking spaces for contaminants as water flows through. The tiny pores are measured in microns. The smaller the micron, the finer the filtration.
Carbon is activated by heat or steam. The activation process opens the pores of a carbon filter, increasing the surface area, and giving the carbon more capacity to hold contaminants. For this reason, all the carbon the filters we used in our products are made from activated carbon in the form of granular activated carbon.
3. UF filter
Ultrafiltration (UF) is a type of membrane filtration in which hydrostatic pressure forces a liquid against a semipermeable membrane. … Suspended solids and solutes of high molecular weight are retained, while water and low molecular weight solutes pass through the membrane.
Ultrafiltration (UF) is a variety of membrane filtration in which forces like pressure or concentration gradients lead to a separation through a semipermeable membrane. Suspended solids and solutes of high molecular weight are retained in the so-called retentate, while water and low molecular weight solutes pass through the membrane in the permeate (filtrate). This separation process is used in industry and research for purifying and concentrating macromolecular (0.1 micron) solutions, especially protein solutions.
Ultrafiltration is not fundamentally different from microfiltration. Both of these separated based on size exclusion or particle capture. It is fundamentally different from membrane gas separation, which separates based on different amounts of absorption and different rates of diffusion. Ultrafiltration membranes are defined by the molecular weight cut off (MWCO) of the membrane used. Ultrafiltration is applied in cross-flow or dead-end mode.
Ultrafiltration can be used for the removal of particulates and macromolecules from raw water to produce potable water. It has been used to either replace existing secondary (coagulation, flocculation, sedimentation) and tertiary filtration (sand filtration and chlorination) systems employed in water treatment plants or as standalone systems in isolated regions with growing populations.  When treating water with high suspended solids, UF is often integrated into the process, utilizing primary (screening, flotation, filtration) and some secondary treatments as pre-treatment stages.  UF processes are currently preferred over traditional treatment methods for the following reasons:
- No chemicals required (aside from cleaning)
- Constant product quality regardless of feed quality.
- Compact plant size.
- Capable of exceeding regulatory standards of water quality, achieving 90–100% pathogen removal.
4. Optionable RO filtration
Reverse osmosis (RO) is a water purification process that uses a partially permeable membrane to separate ions, unwanted molecules, and larger particles from drinking water. In reverse osmosis, an applied pressure is used to overcome osmotic pressure, a colligative property that is driven by chemical potential differences of the solvent, a thermodynamic parameter. Reverse osmosis can remove many types of dissolved and suspended chemical species as well as biological ones (principally bacteria) from water, and is used in both industrial processes and the production of potable water. The result is that the solute is retained on the pressurized side of the membrane and the pure solvent is allowed to pass to the other side. To be "selective" this membrane should not allow large molecules or ions through the pores (holes) but should allow smaller components of the solution (such as solvent molecules, i.e., water, H 2 O) to pass freely.
In the normal osmosis process, the solvent naturally moves from an area of low solute concentration (high water potential), through a membrane, to an area of high solute concentration (low water potential). The driving force for the movement of the solvent is the reduction in the Gibbs free energy of the system when the difference in solvent concentration on either side of a membrane is reduced, generating osmotic pressure due to the solvent moving into the more concentrated solution. Applying an external pressure to reverse the natural flow of pure solvent, thus, is reverse osmosis. The process is similar to other membrane technology applications.
Reverse osmosis differs from filtration in that the mechanism of fluid flow is by osmosis across a membrane. The predominant removal mechanism in membrane filtration is straining, or size exclusion, where the pores are 0.01 micrometers or larger, so the process can theoretically achieve perfect efficiency regardless of parameters such as the solution&pressure and concentration. Reverse osmosis instead involves solvent diffusion across a membrane that is either nonporous or uses nanofiltration with
pores 0.001 micrometers in size. The predominant removal mechanism is from differences in solubility or diffusivity, and the process is dependent on pressure, solute concentration, and other conditions. Reverse osmosis is most commonly known for its use in drinking water purification from seawater, removing the salt and other effluent materials from the water molecules.

5. Booster pump
The purpose of the reverse osmosis booster pump is to increase water pressure going into the RO unit.
Reverse osmosis is a pressure-driven process. Small residential RO units will theoretically operate on very low pressure–down to 35 psi, according to some membrane makers–but the reality is, you won't get a lot of water and the product water quality will be compromised if the unit runs below 45 psi. Low inlet pressure makes the unit produce more reject water, produce less drinking water, fill the storage tank more slowly, and produce lower quality water.
RO units run well on the typical city water pressure of 60 psi, but they run even better with a small pump to boost the pressure to 80 psi or higher.
The white object at left is the transformer. It plugs into a standard wall outlet and converts to the voltage (most commonly 24 volts) required by the pump. The large object is the pump itself. The third device is the pressure switch. It monitors the water pressure in the RO unit& storage tank and turns the pump off and on in response to storage tank pressure. The most common shutoff pressure for under sink home RO units is 40 psi.
6. UV system
The UV Treatment System is a portable ultraviolet-c light (UVC) system that, when properly applied, reduces certain viruses and bacteria on targeted surfaces within passenger transportation systems such as aircraft, passenger railways, buses, ferries, and more.
About the size of an aircraft beverage cart, the system irradiates high intensity 254nm UVC light across entire cross-sections of passenger seating at once. The system can treat a cabin or coach of thirty rows of seating in less than ten minutes, maximizing fleet efficiency and minimizing downtime.
A UV water purifier treats microbiologically unsafe water with germicidal ultraviolet light. The UV wavelength scrambles the DNA of living organisms in the water, so they can no longer reproduce and make you sick. If you drink bacteria-infested water, the organisms can embed in your digestive tract and replicate. Ultraviolet radiation renders bacteria, viruses, parasites, and fungi unable to replicate by damaging the nucleic acids of their DNA.
A UV water purifier exposes living organisms, such as bacteria, viruses, or cysts (like Cryptosporidium and Giardia) to a germicidal ultraviolet wavelength. With enough energy, UV radiation at the 254-nm wavelength disrupts the DNA in pathogenic microorganisms so they cannot reproduce. The ultraviolet light prevents bacteria from spreading disease through drinking water.
UV dosage is the measurement of energy (in MJ/cm²) delivered by a UV water purifier. The more dosage provided, the more energy delivered to treat contaminated water. At a certain threshold, this energy becomes sufficient enough to inactivate most of the microorganisms present in water.
