The five stages of water purification
- 5 microns sediment pre-filter
- The first is a 5 micron spun polypropylene sediment filter. This filter removes all sediment, rust, silt, and other suspended solids larger than 5 microns.
- Activated Carbon pre-filter
- This second stage filter is a granular activated carbon filter removing chlorine, tastes, and odours as well as volatile organic compounds.
- Carbon block pre-filter
- Stage 3 is an activated carbon block filter which removes the same substances as stage 2.
- 50 GPD TFC Reverse Osmosis Membrane
- As with any reverse osmosis system, step 4 is the heart of the system. A thin film composite membrane (semipermeable) which rejects substances except for water molecules. The pore sizes of the membrane are 0.0001µ, Which acts as an excellent filter and is the finest form of filtration known to man.
- Inline GAC filter
- The last stage is the post filter which contains fine granular activated carbon ensuring the water is not just pure but tasty and odourless as well.
Reverse Osmosis Process
The process of reverse osmosis or hyperfiltration was developed at University of California at Los Angelis in 1954. It has since been used widely by NASA, the US Navy and industries such as the pharmaceutical and electronic industries. With the outbreak of cryptosporidiosis in Milwaukee in 1993 its value for drinking water purification was thoroughly realised. Reverse osmosis has become the purification method of choice for drinking water in many households and bottling plants throughout the world.
No wonder, as reverse osmosis has become the best and most efficient method to purify polluted and undesirable water into pure, safe and tasty water.
Reverse osmosis (RO) or hyperfiltration is a separation process that employs water pressure to force water through a membrane that retains the solute on one side and allows the pure solvent (purified water, also known as permeate) to pass to the other side.
More technically, is the process of forcing a solvent from a region of high solute concentration through a membrane to an area of low solute concentration by applying a pressure more than the osmotic pressure.
The reverse osmosis membrane material is a unique thin film composite (TFC) polyimide material. The pore size of the membrane is 0.0001µ which is one ten millionths of a mm. The tiny pores allow water molecules to pass while salt molecules are rejected.
The mineral water question
Water is more important than food or vitamins supplements. We can go for days, even weeks without food, but we can’t survive longer than 72 hours without water.
It is true that our bodies need minerals. It is not true that drinking water containing minerals is good for you. Water contains no vitamins either. A mineral, to be useful to the body must be in a chelated form. The human body has limited capability to chelate minerals.
Compared to plants, this ability is abysmal. The consumption of foods of plant origin supplies the body with minerals it can use immediately because they are in the chelated form.
The function of minerals in the body is to serve as co-enzymes for the enzymes which direct metabolism.
Without its proper mineral, an enzyme cannot function correctly. Reverse osmosis, combined with carbon filters, offers the best solution for purifying water. We get our minerals and vitamins from the good food we eat. Water acts as a carrier.
