ASMC water purification options ensure clean drinking water

With water purification and treatment, drinking and utility water can be preserved and disinfected. We explain what matters when it comes to choosing and using these systems.

What should be considered when purifying water?

When disinfecting water, it is important to follow the correct procedure. Incorrect use can, in the worst case, result in water contaminated with germs, which in turn may cause illness.

Before using drinking water filters for the first time, the instructions for use should be read carefully. These provide information on how the model or variant is to be operated/used in each individual case. In general, there is not much that can go wrong when using water filters. The devices are easy to use and robustly built.

Which type of water purification is the right one?

Before choosing a device for water purification or a chemical method in powder or liquid form, you should keep the intended area of use in mind. Our range includes many different products. Water filters differ in particular in terms of their performance. While some water filters primarily remove pathogens, E. coli bacteria and parasites, others also eliminate chlorine, heavy metals and impurities. Some water filters even improve the taste.

Most water filters are quite light in weight. Many models have a performance of around 0.3 liters per minute. In addition to classic water filters, you can also purchase powder or liquid variants that disinfect and preserve drinking and utility water. With these products, water can be kept potable for several months.

Which product is used for water purification depends primarily on the intended area of application and individual needs. However, you can’t really go wrong with the products from our range, as they come from renowned brand manufacturers and have proven themselves in practice.

Making water drinkable without chemicals

How to purify water from nature

When you’re on the move, it can easily happen that you run out of clean water. If you don’t have a professional water filtration system and also don’t have chemical tablets or powders or water-disinfecting liquids with you, you can use an alternative method with just a few simple means:

Ideally, you should rely on a homemade water filter consisting of several layers. For this you primarily need grasses, sand (clean everything as thoroughly as possible beforehand), and charcoal. A coffee filter is of course ideal and, thanks to its light weight, is something you should always have with you in a pinch, as it is very versatile. Alternatively, you can cut a plastic bottle to size; holes must be made in the bottom for the filtered water to run through.

At the lowest level of the filter you should place the coffee filter or, alternatively, grass and leaves, or even better straw. Then comes a layer of sand or, if necessary, soil. Next comes a layer of crushed charcoal (the charcoal should be broken down into a powder as much as possible). This should be followed by another layer of sand or soil, and finally closed off again with a coffee filter or grasses.

To be on the safe side, the water should be boiled after filtering. Filtering only removes the coarsest impurities, but no disinfection takes place. One last recommendation: running water is always preferable to standing water.

Questions: Water purification

What substances can contaminate water?

There are three groups of contaminants: organisms, chemicals, and suspended solids. In the worst case, four groups of organisms can be present in water: multicellular organisms, single-celled organisms, bacteria, and viruses.

Boiling

does not remove suspended solids or chemicals. However, single‑ and multicellular organisms, bacteria and viruses are reliably killed by boiling. The water should be brought to a rolling boil for at least 10 minutes. The remaining steps for water purification/filtration can be found in our expert tip above.

Germ-free water – what methods are there?

Water purification by boiling: let the water boil for at least 10 minutes and you (basically) have drinking water. Advantages: no chemicals required, no additional equipment, inexpensive and very reliable with adequate boiling time. Disadvantages: you need fuel, the boiling point of water decreases with increasing altitude – while the required boiling time increases, and the taste and smell of the water are not improved; chemical substances may remain in the water.

Chemical water purification:

With this method, pathogens in the water are killed chemically by adding drops, powder or tablets. Advantages: Extremely light and quick to carry out with little effort, small pack size, long-term preservation, disinfection of large quantities of water at once possible. Disadvantages: Taste and smell of the water may be affected, high cost per liter of disinfected drinking water, long reaction times of over 30 minutes, chemical substances may remain in the water.

Mechanical water purification:

Depending on the filter used, bacteria, viruses, and protozoa are removed from the water. Some water filters also have activated‑carbon elements to neutralize taste. Advantages: reliable disinfection, no fuel required, long‑lasting, with activated‑carbon filter improved taste and odor, in some cases even filters chemicals, water can be drunk immediately. Disadvantages: additional weight and pack size, high purchase price, filter elements can clog and require frequent cleaning, pumping can become strenuous.
