This site features drinking water purification systems, whole house and light industrial units, lamps, quartz sleeves, replacement filter cartridges and parts from Pura.Ultraviolet is a safe, clean, easy-to-maintain method of assuring that water is free of bacteria.
We offer all available parts, filter cartridges, components, replacement lamps and quartz sleeves for Pura systems. While traveling through Zambia, Timothy Whitehead became perplexed with the issues surrounding purifying water — chlorine and iodine tablets abound, but it takes 30 minutes to finish the process and the water tastes terrible afterward. Whitehead’s Pure Water Bottle was just awarded a James Dyson Award in the UK and it is now being entered into the international design competition. Whitehead’s water bottle could be an essential tool for people in developing nations, back country hikers and military forces in remote places.

Also I send my call info,if you send an email and give us your contact info, it would be so greatfull. I applaud the effort to use the crank charger for UV instead of general emergency lighting, and combining it with a manual pump filter makes a certain sale for all, me too. First, it is highly unlikely that the very short exposure time is adequate to perform the required function, but cranking it back up a couple times would accomplish this, so thats my first recommendation. The second recommendation is that all reading this understand that the UV only disrupts the ability for what is in the water TO REPRODUCE ONLY.
Allow the water to sit for the full lifetime cycle of the types of organisms known in the area it gets used, and you have safe water to drink. Drink it right away and you WILL still suffer from the amount of LIVE organisms that are in the water, period. This ultraviolet purification lamp is instant starting and utilizes a coil filament, which operates hot. If you have an existing system, just use it as your pattern and source the parts from Ryan-Herco or Harrington or whoever. Unless the drinking water in your area is extremely hard, I wouldn't advice drinking RO water regularly.
Reverse osmosis systems can be built from parts purchased through supply houses or manufacturers.
From your information you are getting ground water (bored water?) and surface water (river, lake).
Before one can comment logically about your application as described, a good set of accredited lab analysis would be required on the untreated water.
Water treatment is often very complex but everyone thinks they have a single panacea recipe of treatment.
I was not clear on the problem and was suggesting that the BAT should have been applied to the problem.
There are chlorine specific membranes as well as membranes that require the removal of chlorine. So before you apply RO, pre-treat the water with a softener as well as remove the chlorine. There are two types of membrane process used for desalination: reverse osmosis (RO) and electro dialysis (ED).

GA Guest IF you're not selling something to proride though he seems to know enough to not be dooped. Sustainable water purification, small scale, is something that seems to be working for NGO's in West Africa where I do a lot of work but none is based on a still, solar or gas, that I've heard of.
This page offers the most commonly ordered parts for current models, which we keep in stock for immediate shipment. The bottle is about the same shape as a regular water bottle and has an inner and outer chamber. He’s engineered his prototype to not only be functional, but also to be ready for mass manufacturing.
Am interested in making this item (if it works as claimed) available for the masses of people who have no access to portable water. This lamp also uses UV-C light to inactivate and kill bacteria, molds, protozoa, viruses and yeasts.
In the case that the lamp shatters, this coating protects the lamp glass from falling into the unit. The UV lamp life is governed by the life of the electrodes and is affected by the frequency of starting. The extremely high purity of the water means that it will leach out vital minerals from your body. If you are planning to build many such systems then you will need to deal with these types of wholesalers or OEMs. It was not clear if all these sources of water are from a single supply (municipal) or if the intent is to treat water anywhere (all sources) with a universal reverse osmosis. I would urge you to get the best information about your source water before considering such activity. If there are suspected periods of time without chlorination then you should select the membranes based on no chlorination. If you obtain the results of testing, I will try to help explain them and fine tune the recommendation as required.
In the RO process, water from a pressurized saline solution is separated from the dissolved salts by flowing through a water-permeable membrane. In some applications, its initial cost is a bit more than chlorination, but because of its low operating cost, it quickly pays for itself.
Whitehead used a combination of a 4 micron-sized water filter and a wind-up ultra violet light system to clean the water of 99.9% of its impurities. It has been 100% scientifically proven to filter water of 99.9% of contaminants and is ready for some big company to pick up the blueprints and start pumping them into the market.
As a result, the glass is contained, making it safer to operate your unit and dispose of the glass. Having said that though, if you have extremely hard water in your area, you'll need to soften it first to prevent the calcium from destroying your membranes. If this is for your own personal use then you should find your supplier in India and discuss parts to build the unit with their sales people.
In your described circumstance I do believe a good water analysis is required before reverse osmosis is applied.

In your case, where water quality is from multiple sources, it will mean that the water quality will undergo frequent change (day to day, season to season).
In which case, the RO unit should have a means of removing chlorine prior to the unit (activated carbon cartridges are often part of the pre-filtering process) .
Your idea to use RO is a good idea and something that I would consider under your circumstance. The permeate (the liquid flowing through the membrane) is encouraged to flow through the membrane by the pressure differential created between the pressurized feed water and the product water, which is at near-atmospheric pressure. We stock Pura original cartridges for most units and excellent equivalent-or-better alternative “after market” cartridges for others.You will need a quartz sleeve only if you break one. Whitehead’s Pure Water Bottle looks to be perfect for the shelves of outdoor stores as well as the small villages of Africa. The fixture is high quality with a long lifespan and low mercury dosage to meet environmental demands. You'll then need to pass the softened water through the RO system to remove the sodium chloride and then use the processed water to dilute your tap water to an acceptable level.
Your taste and odour issues may be something that can be treated more effectively with alternative methods. I would recognize that there may be many problems with water treatment in Kenya and disinfection would be a priority if one must chose between taste and safety. The city utility operator may already have documented results from many samplings and that should be used in your application. When you are getting mostly ground water from the bored wells, the water should be assumed to be hard (review of the test results may give you a better idea). We stock all sizes.For some units there are optional “lamp out” protectors to shut off the flow of water in the event that the UV lamp fails or the power goes off.
You may be able to get good potable water without the use of reverse osmosis but better information is required. Hardness as CaCO3 will cause RO membranes to tear by having the hardness crystals precipitate on the membranes. However much water you normally drink, its contribution to the daily electrolyte requirement is negligible. These optional features are built into new units at the factory and are best ordered at the time the unit is purchased. It is necessary or best available technology (BAT) in some waters with elevated mineral salts.
Softeners are designed to remove calcium, magnesium, and many of the divalent metals like iron and manganese.
