The success of any catering establishment – be it a gourmet restaurant or a small cozy cafe – directly depends on the quality and taste of food and drinks. And they depend on water! Of course, not only from her, but it is unlikely that visitors will be delighted with selected aromatic coffee or seafood cream soup prepared with tap water. For it is not the healing spring that usually flows to us through rusty dirty pipes, but a brown and harmful liquid with an unpleasant taste of chlorine and metal. And it can ruin even the best products.
Therefore, the owners of restaurants and cafes, first of all, need to take care of the availability of water of adequate quality in sufficient volume. The simplest solution may seem to be buying bottled purified water, but after a few weeks it will become clear that this is not economically profitable at all.
The best solution for catering establishments is an integrated water treatment system.
Why is it necessary to further purify water?
Water is a solvent in its properties – it dissolves salts of various metals, it also contains many insoluble substances, each of which affects the human body and household appliances in different ways.
Clean water suitable for cooking and domestic use may contain impurities, but they should not have a harmful effect on humans and damage equipment. However, such water is now rare.
Although sources of centralized water supply vary in different cities, in most cases H2O contains:
Chlorine used to kill bacteria. The liquid from the tap has an unpleasant pungent odor and taste, and causes a number of diseases.
Iron is often present in water that comes through pipes that were laid 30-40 years ago (which is the majority of Ukrainian cities). Iron is also found in well water. You can recognize its presence by the yellowish color of the water and a metallic taste, and with prolonged use – a deterioration in the general well-being of a person, a brown coating on plumbing and red towels and tablecloths.
Hardness salts are the cause of scale on household appliances and kidney stones in humans. You can visually determine the content of hardness salts in water after boiling water – a white precipitate appears.
For restaurants and cafes, water with the above substances is:
– Deterioration of the taste properties of products – even tea and coffee have a specific taste;
– Unpresentable type of plumbing;
– Yellow sheets and towels, from which you can no longer make a spectacular white swan;
– Frequent problems with household appliances (boilers, boilers, washing machines and dishwashers) and costly repairs.
Therefore, without filters for water purification, it is difficult to talk about quality service.
Benefits of Purified Water in Catering
Installing water treatment systems in catering establishments can solve many problems:
– Absence of harmful impurities that adversely affect the health of visitors and staff;
– Excellent taste of dishes and drinks, which are the hallmark of the restaurant, like regular guests and attract new ones;
– Clean water for coffee machines reveals all the flavor notes of coffee beans;
– Compliance with sanitary and hygienic standards;
– Saving detergents;
– Reducing emergency cases of failure of plumbing and other special equipment
To enjoy all of the above benefits in a restaurant, you need to choose and install a water treatment system correctly. The correct choice of equipment also depends on the presence of substances to be eliminated.
Types of water filters
Modern water purification systems eliminate mechanical, chemical and biological contaminants, some systems work in a complex, others neutralize individual impurities.
– ultraviolet cleaning;
– adsorption on activated carbon;
– reverse osmosis.
UV water purification
Water treatment with ultraviolet light allows you to get rid of viruses and microorganisms present in the water. Unlike chemical methods, water treatment with ultraviolet light does not change the chemical parameters of water.
adsorption on activated carbon.
In the process of adsorption, organic impurities, active and combined chlorine, as well as organochlorine compounds (chloroform, trihalomethanes, etc.) are removed from water. This method allows you to purify water to almost zero residual concentration of various elements. Also, sorption purification in industrial filters can remove hydrogen sulfide from water.
Removal of calcium and magnesium salts (softening) is carried out using filter softeners.
Modern softening systems make it possible to remove hardness salt ions from treated water. This prevents the formation of scale on heated surfaces and reduces the risk of deposits on the walls of pipes and surfaces of equipment and plumbing.
Reverse osmosis plants
As filter elements in reverse osmosis plants, semi-permeable selective membranes are used, which pass predominantly water molecules.
To choose one or another method, a detailed acquaintance with the technology of the institution is necessary
