On this occasion, a leading company in the aircraft parts treatment sector has contacted J.HUESA to adjust the water quality of the rinsing baths for parts in military aircraft. J.HUESA after studying the characteristics of raw water, designed, manufactured, installed and commissioned plant water treatment is to subject the desalting until a water quality whose conductivity is less than 10 microsiems .

The facility, which has a capacity of 30 m 3 / h, is made up of a reverse osmosis plant with a previous filtration treatment. As well as accumulation of treated water in the first step, and demineralization in recirculation over baths. Whose operation is explained below:

- The mains water is filtered through a low speed bilayer filter and automatic washing. In which the solids in suspension are retained. Before the water enters the reverse osmosis plant, a sequestrant is dosed to increase the reducing value of the water and eliminate the hypochlorite. With the triple objective of guaranteeing the protection and durability of the membranes, producing a bacteriostatic effect and adjusting the pH. An antifouling-dispersant product is then metered in. To prevent calcium and magnesium salts, among others. These produce incrustations in the membranes and therefore, losses of flow of treated water. best household water purifier price in bangladesh

- The pretreated water goes to the reverse osmosis module. Where it is first filtered through a 5 micron pore size cartridge system. This will retain possible leaks of particles and suspended solids. The purpose of the safety filter is to retain the particles that may leak from the filters or that are introduced with the chemical product. Thus protecting pressure pumps and reverse osmosis membranes.

- Afterwards, the stored water serves as a lung to supply the losses generated in the rinsing baths. As well as for the regeneration of resins and their activation. This water will pass through a filter bed. In order to retain the solids that are dragged into the bath system. All the water will pass through ion exchange resin beds to remove the salts. And thus leave the water conditioned to a quality that does not exceed 10 microsiems.

It includes a control panel for the complete management of the plant with communication. This is done using profibus dp and modbus TCP-IP from Siemens.

The main advantages to consider in the installation in question are the following:

- The system is fully automatic, it can work up to 24 hours a day, with minimal supervision. It does not require personnel with special qualifications.

- The reverse osmosis system supposes a bacteriological barrier in the produced water, which eliminates bacteriological problems in the installation. The sanitization of the membranes is contemplated in the design of the equipment. Assuming a routine operation that can be repeated over time.

We often do not pay enough attention to the issues of water purification in the country. Like, it's okay! After all, there is a well, and the dacha is a temporary dwelling, and the requirements for comfort can be underestimated. So, having provided proper water treatment in their city  apartment , many do not consider it necessary to do this in the country.

Meanwhile, a beautiful pastoral well in the country, pleasing to the eye, may not please other organs very much. The quality of water from underground sources in the region is such that additional purification of water from a well in the country becomes not a whim, but an obligatory condition.

Well or well?

Not all villages and settlements of the Leningrad Region have a central water supply system. And the summer residents themselves often prefer the autonomous water supply of the dacha from a well or well.

When buying a plot with a house, we, as a rule, get along with it a water supply system  , organized in one way or another. When planning the construction of a summer cottage in a new place, everyone faces the choice of a water source. Well or well, what to choose?

voda-na-dache-2.jpgThe answer to this question may vary from case to case. In addition, there are general criteria on the basis of which the choice is made. These include:

The depth of the aquifer: If the water is not more than 10 meters, a well is suitable for your summer cottage; from 10 to 20 meters - both options are possible; deeper than 20 - a well is preferable  ;

Features of the soil: stony soil makes it much more difficult (and, accordingly, more expensive) to drill a well in the country, it is often easier to dig a  well , even if it is deep;

Budget: a well will be cheaper anyway.

Local features

Let us consider the features of suburban water supply using the example of some districts of the Leningrad region.

In many villages of the Vsevolzhsky district, which is popular for suburban construction (Kokkarevo, etc.), wells are most common, since water from deep wells comes in salty. Moreover, the quality of well water there is not high, which makes the problem of water purification very urgent.

Water from wells in the Vyborg region is oversaturated with iron, analyzes show serious excess of the maximum permissible concentration. The depth of drilling wells varies significantly within the region: from 30 meters in the village. Leipyasuo, up to 180 meters - in Pervomaiskiy. Meanwhile, wells in the same Pervomaiskoe are usually dug to a depth of seven meters, which is incomparably cheaper than a well over 100 meters. But water from a shallow well, of course, requires cleaning, as it is exposed to a wide variety of pollution. best household water purifier price in bangladesh

Those who plan to equip a well at their dacha in the Priozersk region should also be prepared that drilling to a depth of 190 meters will be required (the minimum well depth in this area is 26 meters, in Priozersk). And even the deepest well does not guarantee that your water will be of drinking quality: you will need filter systems to purify water from iron, manganese and fluoride salts.

Due to the large amount of flowing clays, well water here is often cloudy, in addition, it requires  cleaning from iron , organic compounds, and other contaminants.

No matter where your summer cottage is located, no matter what source of water you use, no matter how clean the water may seem, to ensure the safety of your family members, you should take care of a water purification system.

Systems and filters for water purification in the country

Many are held back by the allegedly too high cost of such systems. But the volume of water consumption in the country is always lower. And the purchase and installation of a treatment plant with low productivity will be much cheaper. This relatively small investment will be more than repaid with the benefits and benefits of using clean water!

In principle, water purification systems for summer cottages do not differ from installations with higher productivity intended  for cottages . They can be both specialized (for example, for cleaning from iron), and complex,  "5 in 1" .

To provide a family with drinking water in the country, you can purchase a  bulk or flow-through  household filter for water purification. Or, to save money, you can take such a filter from your city apartment for the summer, which will still be empty!

How to choose a filter for water purification in the country?

Obviously, in order to choose the right filter for water purification, you need to know what exactly you need to purify water from. An analysis will help to find out what is the contamination of the water in a well or a well at your dacha.

Water analysis  is the first necessary stage in the device of a purification system for a summer cottage. The composition of water can vary significantly in wells located close to each other. Therefore, you should not be guided by the words of your neighbor - the water at his dacha may be completely different, despite the proximity of your plots. Moreover, the water in shallow wells can change its composition even depending on the season.
