Coarse water filter: fine and mechanical, sumps for water supply systems, mesh sump

For drinking needs and proper operation of the equipment you will need high-quality water. To clean the liquid, filter systems are installed. There are several varieties of cleaners. Familiarization with each option will help you choose the right mechanical filter.

Varieties of filters for rough water purification from wells

When choosing cleaning equipment, attention should be paid to simple designs. Multifunctional varieties often break down, and complex mechanisms are not needed for cleaning. To filter water from the well, devices that are selected by the amount of solid suspensions in the stream will be required. It is also worth considering the amount of water consumed per day.

Varieties of filters for rough cleaning of liquids:

• Mud collectors;
• Mesh;
• Cartridge
• Bagged;
• High speed.

Sumps are simple but effective designs. It is mounted at the direct inlet of the flow and suspended with a size of 300 microns. For external signs, the structures are divided into vertical, horizontal and U-shaped.

Mud muds are commonly used in wells with intense flow or saturated with large suspensions. To expand the functionality, additional mesh devices are used.

These designs have their advantages. Among them, a high degree of purification, work at a temperature of +150 degrees and a pressure of 6 MPa are noted. Also, mud collectors perform their functions for a rather long period of time. But it is necessary to constantly monitor the hydraulic resistance.

The device diagram includes a removable bottom, a side hatch and a device for bleeding air masses. Behind the principle of installation, the dirt collectors are divided into welded and flanged ones. You can use the equipment without registration with supervisory authorities.

Strainers include a web in a mesh with mesh sizes from 20 to 500 microns. When buying this unit, you need to pay attention to the functionality. Some designs are equipped with a backwash system, which simplifies maintenance, as the filters are self-cleaning.

Cartridge models are a cartridge system. This is a bulb case with several cartridges. These filters have earned their popularity due to a wide selection of models, separation into warm and cold water, the ability to hold suspensions of up to 30 microns.

Cons of cartridge options:

1. Cartridges are often clogged, especially to wells where sand has broken through;
2. Requires constant monitoring and adjustment of pressure;
3. Cannot be used for heavy streams.

But cartridge models do a great job of filtering and remove even the smallest particles. A variety of these filters are bag options. The case is filled with granules. Such designs are quite effective, but expensive. Flushing of such equipment is done by professionals.

Industrial filters are represented by high-speed models. This is how the primary processing of the liquid occurs. It looks like a flask filled with filter material.

Mechanical water purification filter device

The mechanical cleaning filter is designed for coarse filtration of water. The main goal of the design is to pass water through the cartridge, which traps insoluble suspensions. In this case, no chemical processes occur. Bulb filters quickly become clogged and impede fluid passage.

For drinking water, this method of treatment is ineffective. Most often it is used for home appliances.

There are several types of mechanical cleaners. These include the mesh version. But due to the small area, filtration is significantly slowed down. To increase coverage, use flasks with a similar mesh inside. But replacing the cartridges in this case still needs constant. The cleaning speed depends on the pressure of the water.

The principle of operation of the filter is the passage of fluid through the mesh fabric. In fact, the whole structure has a more complex mechanism. Polypropylene fiber is used as a filter material. A small inch of gaps allows you to effectively remove salts and suspensions.

Some options are able to get rid of not only mechanical excess, but also bacteria. But at the same time, impurities of chlorine and heavy metals remain in the water. A plumbing filter is used to clean the water supply throughout the house.

Features of strainers

To clean water, they often resort to filtration. For drinking water, it is worthwhile to purchase both coarse and fine cleaning mechanisms. But for plumbing, a mechanical cleaning device is quite enough. The filter can be single or three-stage. The most popular among cleaning equipment are mesh filters.

The mesh version is placed on any plumbing system. It can be installed before entering the washing plumbing, to fine filters, as well as in front of pumping systems.

Often a small net can be found on water taps. The design of this option includes a metal housing, flange elements, a cylindrical filter mesh. The housing itself is closed with a dummy nut.

Pluses of the mesh filter:

• Simple construction;
• Ease of operation;
• Can be washed;
• Available and inexpensive parts;
• Cheap filter cost;
• Environmental safety - the use of natural materials.

The disadvantages include low efficiency, since the grid delays only large suspensions. But there are models with finer refinement. Also disadvantages include the inability to filter chemical contaminants.

Use of mud sumps for water supply systems

Among the mechanical devices for water supply systems in an apartment, the most often used are mud collectors (strainers). It looks like a metal case with a cylindrical mesh inside. The design is simple but effective.

Functional features of the mud collectors:

1. The nature of the mud: for fine and coarse filtration;
2. Type of flushing can be flushing, self-cleaning, non-flushing;
3. Mounting method to pipes: with thread or flanges.

The sump device refers to hard cleaning. Such mechanisms are installed on the water pipe and for heating systems. They purify water from suspensions and large impurities.

The principle of operation of the mud sump is quite simple. After moving the water through the pipes, the liquid is sent to the inside of the filter. There, solid residues settle to the bottom. Then the water moves through the net. To remove sediment, the cylinder must be removed and flushed.

Efficient operation of the sump is possible only with a smooth increase in hydraulic resistance in front of and after the filter.

Among the advanced technologies on the market, the quite popular German magnetic sump. A special magnet attracts all excess water. In this case, the fluid flow itself retains its natural course.

Installation and maintenance of sump filters

Plumbing needs preliminary water treatment. So the mechanisms will last a long time and properly. But for efficient operation, proper installation and maintenance of the water filtration system is necessary.

Installation Rules:

1. It is best to mount in front of the meter. Due to its small size, this installation is difficult. That is why an oblique filter is mounted.
2. The oblique design is installed on horizontal elements of the pipeline. The flask is mounted below. Take into account the direction of the water flow. The equipment case is equipped with an arrow for this.
3. The direct mechanism is installed only on horizontal pipes. It is necessary to provide a place for removing the flask.
4. For direct flushing, a backwash device must be installed. This is achieved by equipping a bypass loop with several taps to switch the water flow to the oncoming one.

When operating the device, you will have to periodically disassemble the structure for cleaning. The sump and sump most often need cleaning and replacing cartridges. Before starting the filter, the pressure of the line is removed by shutting off the water.

Dirt is removed from the bulb during cleaning. Then washed the mesh and purged with compressed air. Damaged items must be replaced.

Slanting mechanisms have plugs with hex caps for a wrench. Direct filter flasks can be removed with a wrench or a figurative wrench. When reassembling, it is advisable to change the gaskets.

The nuances of using a fine filter

Fine filters are quite diverse. There is an anti-lime mechanism, deferrizing, clarifier, water softening system. Such designs work by passing fluid through different filler options. The grid delays the suspension, and the purified water goes on.

The composition of the water at the outlet is determined by the size of the mesh cells or the type of filler.

Fine cleaning is applied after coarse filtration. Often, all the flaws of the preliminary systems are caused by poor-quality water pipes. The fine filtration system can be placed in multi-stage versions to improve cleaning. Often such a filter is used in reverse osmosis systems.

Mechanical cleaners play the role of pre-filtering hot and cold water. For drinking liquids, it is often necessary to install a deep chemical cleaning filter, but for household plumbing this is enough. Mechanical structures work with the help of special mesh materials or granules.
