Dear Friends of Steveston United Church:
Your past generous support of Steveston United Church’s Annual Christmas Bazaar is very much appreciated. Your contribution of a gift certificate or a new item which can be auctioned would be greatly appreciated. The proceeds from the Christmas Bazaar are an important part of Steveston United Church’s annual income which allows us to donate to various charities.
Chair, Christmas Bazaar CommitteeJean Burgess
Thank you very much for sponsoring the Forever Young 8K Walk / Run for seniors. We couldn’t have done it with out your support. Hope to see you at Garry point on Sunday Sept 13th.
Once again, we can’t thank you enough for your help!John & Joan Young
Activated Carbon Filtration
Activated carbon works via a process called adsorption, whereby pollutant molecules in the fluid to be treated are trapped inside the pore structure of the carbon substrate.
Carbon filtering is commonly used for water purification, in air purifiers and industrial gas processing, for example the removal of siloxanes and hydrogen sulfide from biogas. It is also used in a number of other applications, including respirator masks, the purification of sugarcane and in the recovery of precious metals, especially gold. It is also used in cigarette filters.
Active carbon filters are most effective at removing chlorine, sediment, volatile organic compounds (VOCs), taste and odor from water.
Ultra Violet Sterilizing
Ultraviolet germicidal irradiation (UVGI) is a disinfection method that uses ultraviolet (UV) light at sufficiently short wavelength to kill microorganisms. It is used in a variety of applications, such as food, air, and water purification. UVGI utilises short-wavelength ultraviolet radiation (UV-C) that is harmful to microorganisms. It is effective in destroying the nucleic acids in these organisms so that their DNA is disrupted by the UV radiation, leaving them unable to perform vital cellular functions.
5 Micron Sediment Filtration
These ratings are usually stated in micron size. The micron is a standard measure of size that is used by filter makers. The diameter of a human hair is about 90 microns. Sediment filters are used to catch particles 1/300 of that. For many uses with residential treatment virtually any filter style works well.
For example, a 5-micron wound string sediment is the traditional filter of choice as prefilter for a residential reverse osmosis unit. It serves the purpose–protecting the carbon filter that follows it or the RO membrane from incoming dirt and debris–quite well.
Absolute, theoretically, means that the filter will reject virtually all of the particles of the given size. The usual expectation is a 3-log rejection–or 99.9%. Absolute ratings are usually used for the tightest filters and for purposes where efficiency really matters. For example, if a filter maker promises removal of E. coli, more or less 85% efficiency isn’t good enough. If you’re going to trust your life to the filter, you expect an absolute 3-log or 4-log rating at the very least.
Reverse osmosis (RO) is a water purification technology that uses a semipermeable membrane. This membrane technology is not properly a filtration method. In reverse osmosis, an applied pressure is used to overcome osmotic pressure, a colligative property, that is driven by chemical potential, a thermodynamic parameter. Reverse osmosis can remove many types of molecules and ions from solutions, 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 the solvent) to pass freely.
Ozone is a colorless gas made up of three atoms of oxygen. Ozone (O3) is a powerful sterilent that oxidizes mold and mildew, pollen, odors, and other airborne organisms upon contact, rendering them inactive, leaving behind pure clean oxygen, O2, in the air.
What type of bottled water do you recommend?
Health Canada recommends that people whose immune systems have been weakened by disease, surgery, or therapy, consume bottled water that has been sanatized in some manner to eliminate harmful bacteria (e.g., ozonation). These individuals should contact their physician for advice on the types of water to consume and how they should treat their drinking water.
All bottled water meeting or exceeding the federal standards are comparable from a health and safety perspective for the general population. A consumer’s choice of bottled water is likely to depend on their needs and taste preferences.
