In part one of this ten part series we created some broad water categories. Treated and untreated, potable and non-potable. Before proceeding any more you should categorize your water. In the event that you recall, treated only deals with disinfection for microorganisms, and potability pertains to every form of contaminants and whether they exceed EPA regulations. So, now that you’ve categorized your water, you should identify your specific water issue. With this we identified four more categories; sediment, taste & odor, dangerous contaminants, and the nth degree. The others of this article will pertain to sediment filters.
Let’s focus on simple sediment issues. There are many ways that sediment appears, and each circumstance is unique. So, where should you begin? At the fundamental level you need a whole house filter system. Why whole house? Because sediment impacts everything. It’s more than a drinking tap water issue, though you almost certainly don’t wish to drink it, but it collects in heated water heaters hurting their efficiency, it wears on components in your washer, and stops you from getting truly clean clothes etc… It’s a complete house problem, so you need a whole house sediment filter.
Before I give you a good example of a complete house sediment filter, we must address system size. Unfortunately, for reasons beyond understanding, many water filter manufacturers label their small water filter housings as “whole house” water filter housings, but they really are not. There are five industry standard water filter housing sizes that utilize industry standard size cartridges. They are (based on filter cartridge size) 5″ x 2.5″, 10″ x 2.5″, 20″ x 2.5″, 10″ x 4.5″, and 20″ x 4.5″ (see our previous article for more details). So many homeowners are troubled by way of a water filter housing that is way too small. water filter supplier in Dubai A more substantial housing is superior atlanta divorce attorneys way. Flow rates will undoubtedly be higher, pressure loss will undoubtedly be lower, time between filter changes will undoubtedly be longer, and water filter cost will undoubtedly be less per square inch (kind of like buying greater bottle of Mayo). For whole house situations don’t use the 5″ x 2.5″ or the 10″ x 2.5″ water filters, they are created for much smaller applications like campers or drinking tap water systems intended to supply a small drinking tap water faucet. With that said, the following water filter housings are the proper size for whole house applications: 20″ x 2.5″, 10″ x 4.5″, and 20″ x 4.5&Prime ;.
Now we need to discuss water filter cartridges. This really is where your previous categorizing work pays off. When you have untreated water you actually need in order to avoid cellulose media. Cellulose is commonly present in pleated cartridges, but a few manufacturers also make pressed cellulose cartridges. Cellulose originates from plants and is therefore food for just about any microorganism fortunate enough to get your filter, where they will live, grow, multiply and possibly cause dangerous threats to your health. Untreated water needs a bacteriostatic filter media. Bacteriostatic implies that microorganisms are unable to live and multiply on the filter. A standard bacteriostatic media is polypropylene, though polyester is to. There are two typical forms of polypropylene water filters; string wound and blown. The string wound water filters appear, as the name indicates, to be a spool of tightly wound string. The blown come from exactly the same polypropylene, however the poly is heated and melted then blown out of a rifle and spun onto a tube, not unlike cotton candy. They have identical performance, and are great for sediment removal from untreated water. For better flow and lower pressure loss look at a pleated polyester sediment water filter. The pleats provide the filter more area than a poly string wound or poly blown water filter.
For treated water you need to use the filters mentioned previously, but there’s no reason to use anything apart from pleated cellulose. As mentioned previously, the pleats offer significantly greater area, thus higher flow with lower pressure loss. Pleated cellulose water filters usually are the prime choice for treated water. Lastly, I want to remember to say RUSCO water filters. They are sediment filters made to eliminate large particulate over 75 microns. RUSCO’s are usually used as whole house water filters, and may also be used to filter irrigation water to protect the sprinkler heads from sediment. More than anything, the RUSCO’s most famous feature is reusability. RUSCO’s are constructed with a flush valve to clean out the collected sediment. No filter changes, however they don’t work very well with small sediment less than 75 microns.
