Choose a filter for rough water treatment for an apartment

Coarse water filters for apartments (FGOV) delay relatively large insoluble elements, for example:

• rust components;
• scale from welding, seals;
• sand.

Therefore, FGOV must be installed in the apartment.

How do the SPF work

Their work is based on the mechanical retention of large particles. The devices have differences in:

• parameters;
• form;
• bandwidth capacity;
• the highest operational period;
• cleaning blocks;
• manufacturing materials;
• method of purification;
• type of filter component.

Types of SPF

Consider the types in more detail:

1. Reticulate. This is one of the most common varieties. She has a high service life without replacing the working component. In the grid, the cells have parameters of 50 - 400 microns. The device is made of stainless steel. Differences in net species are associated with the method of their entry into the pipeline, the methods of regular cleaning and service.
   These devices are divided into two subcategories:
   1. With backwash. Settled components are automatically removed.
   2. Without such a rinse. You can clean the device only by disassembling it.

   Devices working with cold water have a transparent case. So you can monitor the condition of the grid.
   Devices operating with hot water, metal. After all, metal copes with high temperatures.
   Many models have other functions. For example, they may incorporate a valve to adjust the pressure. They can be combined with a pressure gauge. This is a safety measure for the internal space of the pipeline and household models from pressure surges.
   It is logical to install devices with automatic flushing where there is a drainage pipe and dirty water with impurities follows in it.

   Pros of mesh models:

   1. Simple and efficient design.
   2. Acceptable price.
   3. Ease of installation, use and maintenance.
   4. No consumables needed.
   5. They work in domestic and industrial networks with any water (hot and cold).

   There are also disadvantages, but conditional:

   1. For routine maintenance, water must be shut off.
   2. Relatively low cleaning rate.
2. The second type of SPF. Flange and coupling. They differ in the method of connecting to the highway. If the diameter of the pipe is more than two inches, it is better to use a flange view. Bolted connections allow you to remove the device without dismantling the other components of the structure. Feed-through models are placed on pipes during system design.
   If the pipe has a smaller diameter, the coupling model is activated. Usually these are residential and private networks. The device is directly screwed onto the pipe or connected to it with the help of American women.

All FGOV have similar installation criteria:

1. For pipe insertion, scale, corrosion and other dirt are eliminated.
2. Overlapping water.
3. Any sealant is wound on the threaded section of the instrument cover. The same processing is carried out with the connecting section of the device and the pipe.
4. The filter component during installation is directed to the bottom.
5. The device is attached with a clamp. There, mechanical wear is reduced.
   All filters have nozzles (one at the inlet, one at the outlet) and a sump that purifies the water. By the type of position of the sump, the device can be straight or oblique.
6. Direct version at the entrance to the apartment. In it, the sump has a vertical position to the flow. Its size is large. The quality of the purification is better because of this. Water flow rate decreases. Large particles sink to the bottom.
7. Oblique version. The position of the sump to the flow is at a slight angle. The device is placed when the pipe is arranged next to the wall or floor. Flange covers or coupling plugs are used to close sedimentation tanks.
   Clauses 3 and 4 have different methods of purification. Used devices with auto-flushing and without this option.
8. Cartridge models.They are attached to the wall. They have a flask. It can be transparent and opaque. Inside it are replaceable cartridges. The materials for their manufacture are as follows:
   • polypropylene fiber, processed by the press;
   • polyester;
   • twisted thread.

   They have different purification potentials. But the coarse purification parameter is 20-30 microns.
   With these devices, you can often change cartridges. Devices themselves are usually placed where there are small garbage components that poorly catch mesh models.
   The cartridge traps such particles. A charcoal fiber cartridge can remove chlorine from water.
   Installation of these models takes place where weak flows are noted. In conditions of strong flows, a large-sized device is used.

   Note! The cartridges do not auto wash. They have to be changed.
9. Speed ​​models. They are needed when you need to remove insoluble various impurities. They have special stainless tanks.
   The filter component is located in the housing. In the upper zone of the device there is a unit that automates the cleaning process. The level of water purification is 30 microns.
   But such rough filters also have disadvantages:
   • solid parameters;
   • placement in rooms with heating;
   • Necessarily need an additional drainage pipe for restoration.

Installation and maintenance

In this activity, you must adhere to the following criteria:

1. It is better to place the device in front of the counter. Although in reality there is not enough space for this. For this reason, an oblique modification is put. It protects the mechanism from blockages by weighted elements and protects the counter from damage.
2. You need to put the oblique model on the pipe with a horizontal position. The flask is placed below. So washing is facilitated. It is important to know the direction of flow. Usually there is an arrow on the body of the device reflecting this direction. You can mount the oblique device on a vertical pipe. Only the flow should follow from top to bottom. If such a device is mounted upward with a sump, then dirt will not penetrate the system, but the probability of a device breakdown will increase. After all, this dirt will prevent the opening of the faucet.
3. Direct model. It is placed only in the horizontal zone of the water supply. There is some room for the removal of the flask (if necessary).
4. The direct flush unit is also complemented by the automatic flush option. For this, a bypass water loop and several faucets are mounted. They can convert the direction of flow to the opposite.

When using a filter, you will need to disassemble it several times to clean or replace the screen or cartridge.
Before disassembling the device, it is necessary to eliminate the pressure in the network. To do this, the water supply is stopped.

In oblique models there are traffic jams with convenient covers, which have six faces. This is made specifically for the wrench. The paranitic gasket is removed. Putleva winding. So the connections become more airtight. And further improves the functionality of the device.
The flask for direct filters with a vertical position can be removed with a wrench. The flask is put back with new gaskets.

You can remove dirt from an oblique model as follows: the model is disassembled, the dirt merges. The mesh is retrieved. The pollution is removed. This zone is dried with compressed air. The damaged grid is changing.
In direct modification, the flask is unscrewed. A sediment pours out of it. The grid is washed. Dries. Or put a new cartridge.

It’s easier to work with auto-washed models. The tap at the bottom of the flask periodically opens. The grid and flask are cleared. A pressurized water stream is used. Then the water should be drained or in a substituted container.
For more convenient operation, an automatic flushing device is placed on the water supply itself. Then the water flows in the opposite direction. And cleaning the grid is more efficient.

Today on the market there are many models of FGOV. The following is the TOP 5 most common devices.
