Water is a key resource in everyday life and industry. Contaminated water can cause health issues, damage household appliances, or technologies in production. In this article, we will advise you on how to ensure clean and safe water at home and in industry.
Water filtration and treatment serve different purposes in homes and industry. In homes, people choose filters mainly to ensure healthy and safe drinking water free from impurities, microorganisms, chlorine, odour, or unpleasant taste. Clean water also plays an important role in protecting household appliances such as dishwashers, washing machines, boilers, or coffee makers. Mechanical impurities and limescale not only shorten the lifespan of these appliances but also increase the consumption of cleaning agents.
In industry, the key is to protect technologies from impurities and limescale, which can cause significant damage. In certain sectors, such as food, pharmaceuticals, or the chemical industry, water filtration is also important to ensure hygiene standards and the required quality of output products.
In industry, the requirements for water quality differ from those in homes
So, what exactly do we filter out of water? These include mechanical impurities (sand, rust, microplastics), chemical substances (chlorine, nitrates, heavy metals, pharmaceutical residues, etc.), microorganisms (bacteria, viruses, algae), and excess minerals (calcium and magnesium), which cause hard water.
The selection of the right type of filter must be preceded by a laboratory water analysis, which will show you the composition of your water. From the analysis, you can determine which substances and impurities exceed the permissible or recommended values and therefore need to be removed from the water. There are also multi-purpose devices that contain several types of filters.

Water filters and treatment plants can be installed at the entry point, filtering all water entering the building, or only at one tap.
In homes that draw water from their own sources, we definitely recommend a well water filter at the entry point, which will be designed and installed by professionals. If you have water from waterworks and only want to improve the quality of drinking water, a tap carbon filter under the sink, which you can install yourself, or a filter jug will suffice. Hard water filters, or water softeners, are then a suitable addition for the water supply to the washing machine and boiler.
For a family house with its own water source, an effective well water filtration solution could look as follows:
Mechanical filtration and disinfection at the entry point,
iron water filter from the well,
carbon filter for tap water in the kitchen,
softener for the boiler and washing machine.
The quality of drinking water is important for our health
In industry, more robust solutions are necessary, such as flange filters, which can handle high flow and pressure. For smaller operations, threaded filters may sometimes suffice. However, you must also decide whether to invest in central filtration (entry point filters) or manage with local technology. The requirements for water filtration in industry are very individual, and therefore its design and installation should be handled by professionals.
Water filters and treatment plants in homes and industry require regular maintenance depending on the type of filter. Mechanical filters need to be regularly cleaned by flushing, or you can purchase a filter with an automatic flushing function, so you don't have to think about maintenance at all.
In carbon water filters, regular replacement of the filter cartridge is necessary, and special salt tablets need to be inserted into water softeners. During maintenance, follow the manufacturer's instructions and recommended intervals, but if you notice a deteriorated taste, colour, odour, or reduced water pressure, do not wait with filter maintenance.
To choose the right type of filtration, you must consider 3 key criteria:
Types of undesirable substances, which you will find out from the water analysis,
water source (waterworks, private well, or borehole),
purpose of water use (filter for drinking water, utility or rainwater, or filter for special industrial applications).
Also focus on operating conditions and choose the required flow and pressure based on water consumption, water temperature, and appropriate connection. If you require a maintenance-free solution, choose water filters with an automatic flushing function.
A major mistake is choosing and installing a water filter without sufficient knowledge of the functions and purpose of individual types of filters or operating conditions. In practice, we often encounter people looking for a water filter without knowing the composition of the water. However, each filter removes different impurities from the water, and therefore without analysis, the right solution cannot be chosen. An incorrectly chosen filter not only fails to solve your problem but can even reduce water quality.
If you do not know how to read the water analysis and how to choose the appropriate type of filter and water treatment for home or industry based on it, do not hesitate to contact us. Our experts will be happy to provide you with advice on purchase.
