How to refill a "disposable" Brita brand water pitcher filter with activated carbon. Activated carbon is also known as activated charcoal and is a VERY effective substance at absorbing many unwanted contaminants in drinking water and other liquids. The History of Activated Carbon Activated Carbon was first known to treat water over 2000 years ago. However, it was first produced commercially at the beginning of the 20th century and was only available in powder form. Initially activated carbon was mainly used to decolorize sugar and then from 1930 for water treatment to remove taste and odor. Granular activated carbon was first developed as a consequence of WWI for gas masks and has been used subsequently for water treatment, solvent recovery and air purification. The unique structure of activated carbon produces a very large surface area: 1 lb of granular activated carbon typically provides a surface area of 125 acres (1 Kg =1,000,000 sq. m.).
Activated charcoal is good at trapping other carbon-based impurities ("organic" chemicals), as well as things like chlorine. WATER PURIFICATION SYSTEM, cheap and effective. SO YOU HAVE an emergency supply of water, but you're not sure how pure it is. Here is an excellent, cheap setup you can easily DIY for purifying LOTS of water. It's based on the Berkey ceramic water element filtration system that's been around for a long time. LOOK ON AMAZON FOR "DOULTON" FILTERS. The ceramic material will filter down to .5 micron (that's 1/2 of a millionth of an inch) and according to the manufacturer will eliminate bacteria like E. coli and salmonella, and parasites like Crytposporidium and Giardia, microscopic impurities that will cause serious health problems and even death.
A colleague of mine who has a great deal of knowledge in the area of food safety has studied this setup carefully and I have built a system per his recommendations. My primary system has 3 filters and will be used if I need to purify questionable water. TWO COMPLETE SYSTEMS needs 4 bottles, 4 elements, 2 spigots, and can be made in a couple of hours if you have all the tools located. How to restore headlights on a budget! The problem with most plastic headlights is that they come with a very thin "protective coating" that is supposed to lessen the effects of rock chips and possibly deterioration from UV exposure. Unfortunately, these coatings don't last very long and tend to turn opaque as they age. The goal with the sanding is to get rid of this coating altogether. It is a good idea to either remove the lens you are working with, or tape of the surrounding area so that you don't accidentally sand the paint.
Start with your 1500 sandpaper, and grab a little cup of water. Using plenty of water, sand the headlight lens for at least 10 or 15 minutes. Once you have an even surface with no coating remaining, you can move to the 2500 sandpaper. Note: When you are done, the surface should be very smooth, but it will not be clear yet, it will still be foggy from the sanding. 55 gallon barrel dry well. Installing a French Drain. If you live in a part of the world that receives a fair bit of rain, then you are probably pretty mindful of water and how it effects your property.
I live in the beautiful state of Maryland. My home is built on clay soils. And when it rains you can bet that not all of that water quickly percolates through and into the earth. The purpose of this "how to" is to serve as a visual reference for constructing a hidden drainage ditch in your yard if you have limited standing water issues on your property.
A common term for this kind of approach is a "French Drain" Oh disclaimer time: Before you dig ANYWHERE, make sure you contact your local utilities people. Alright? Cyclonic filtration - Overview. Dust Sniper (quiet extractor system) In this project we turn a bunch of old free stuff, including two old household vacuums into what is arguably the most useful and necessary of workshop tools: the dust extractor. But why stop there? Lets make a really fantastically effective dust extractor, one that is whisper quiet, never stops sucking or plagues you with blocked filters, one that is versatile enough to take dust from a variety of power tools, one that turns on and off on its own so you never forget, and most important of all, one that does a good job of extracting the small - most deadly - particulates from the air you breath... Step forth, 'The Dust Sniper'.
This project was borne out of my dissatisfaction with commercially available dust extractors. After a fair bit of research I purchased one of the more expensive 'quiet' workshop vacuums, and was not happy with its performance (I sent it back unused after taking a dB reading of it). This DS ended up costing about £20 total. My kingdom for some silent clean air. Backyard Rain Barrel. You will need a suitably sized container. My choice is a 200 L bioprocess container. It used to hold glucose. You can acquire these barrels from various sources. I got mine free from a local manufacturing company. They throw things like this out or back into recycling all the time. Another viable option is a local carwash, they have large barrels for detergent that they need to dispose of all the time. You will also require: Power drill Rubber mallet Drill bit (3/4 inch) teflon tape 3/4 inch spigot union (this is going to be snug fit) 3/4 inch black connectors plumbers putty plumbers adhesive standard house spigot (which should also fit a 3/4 inch fitting.
Step1: Drill the hole into the barrel near the bottom (but not at the bottom (see figure 2). Cyclonic Dirt Separator Using Off the Shelf Parts.
