Filter jug: will my water be clean?
The simplest water filter for home is a jug. It has been used for many years to purify water.
Pitcher Filter Device:
It is a transparent plastic container in the form of a jug with a lid. Inside it is a cartridge with filter material.
There are two types of covers for such devices:
- with a hole for filling water;
- removable;
Sometimes silicone pads on the bottom and handle of the jug are provided in order to ensure its maximum stability and comfort of use. Water is poured into a special funnel with a cartridge and passes through the filter material, after which it accumulates in its lower part.
Jug filter working principle:
The main element of this device is a replaceable cartridge. It is a housing made of food-grade plastic, with holes in the upper and lower particles. From above, a special cone is usually provided for uniform collection and distribution of water in the loading layer.
The first element that water passes on its way is a mesh of polymer material. It removes large mechanical particles.
Next, the water enters the backfill of the cartridge, which consists of several materials:
1. Ion exchange resin to reduce stiffness and, therefore, prevent the formation of scale. On its surface there are fixed sodium ions, which, in contact with hard water, are exchanged for safe sodium. Also, ion exchange resins can remove small amounts of heavy metals.
2. Activated carbon – it adsorbs:
- natural organic substances that cause the color of water and unpleasant odors;
- chlorine, respectively, an unpleasant pungent odor disappears;
- toxic pesticides and organochlorine that appear in water from effluents of industrial enterprises and in the process of chlorine disinfection.
3. Catalytic materials. They have specific properties for accelerated oxidation of certain impurities, including manganese and iron, thereby reducing the metallic taste.
To prevent biological fouling in such filters, the charge is sometimes impregnated with silver ions.
4. At the bottom of the cartridge is an inert material that performs a drainage function (holds the load in the cartridge).
Each manufacturer creates a loading recipe independently. It depends on the quality of the water, the required resource, etc.
Typically, such a cartridge works for 1 to 2 months, depending on the volume of material, the quality of the source and the amount of water consumed.
Cartridge replacement:
The process includes 5 stages.
- Remove the cover and remove the old cartridge.
- Rinse all filter parts under running water, while dishwashing detergent can be used.
- Soak a new cartridge for 5 to 10 minutes.
- Install it in the funnel.
- Pass 2 portions of water through it and pour them.
- After that, you can drink water.
Jug Filter Rules:
- Use only for tap water.
- Follow the frequency and rules for replacing cartridges.
- Not intended for hot water (maximum temperature 35 to C)
