Review of Unilos Astra septic tanks and principles for choosing models

Comfortable living in a country house or country house is impossible without the organization of individual sewerage. Not all villages have centralized networks for organizing household amenities. In most cases, you have to take care of this yourself.

This is where the Unilos Astra septic tank will come to the rescue - excellent equipment that can perform the function of cleaning the waste of the whole family for many years.

We will tell you in detail about the design and operating principle of the purifier, outline its pros and cons, and also provide practical recommendations for the operation and maintenance of the unit.

Design and principle of operation of septic tanks Unilos Astra

The design of the station provides for the gradual removal of contaminants in four series-connected tanks enclosed in one housing:

• Receiver

This is the primary sedimentation basin for heavy sediments, connected to the sewer line. This is where small and large solid particles from kitchen sinks or plumbing fixtures settle to the bottom. The liquid moves through the mamut pump for the next stage of cleaning.

• Second camera

Aerobic biological purification reactor that converts pollutants into sludge. In it, under the influence of bacteria, fat, chemical compounds and microparticles that do not settle in the receiving area are broken down.

The liquid flows further through a grease filter that retains the film on the surface of the drain.

In an aerobic reactor, microorganisms are generated within a month from the start of Astra’s operation. The number of users is regulated by the manufacturer for each model.

If operating conditions are violated, bacteria are introduced artificially - a special mixture is purchased and poured into the home sewer.

• Third compartment

Separates sludge deposits. The old ones fall to the bottom, and the new ones return to the second tank for further processing.

• Fourth tank

Pure water flows into it with a purification degree of up to 98%. The autonomous station produces process water with hygienic characteristics, suitable for watering plants or washing buildings and cars.

Compliance of the degree of purification with SanPiN standards and the environmental safety of the process are confirmed by sanitary and epidemiological conclusions.

Technical characteristics of Unilos Astra 3, 5, 8

VOC Astra engineering systems are classified according to the volume of liquid waste received. The numbers in the labeling are the maximum number of people for which a particular model is designed.

Order installation of a septic tank

If the house has bulk plumbing (bathtub or jacuzzi), then its volley discharge must be taken into account. For example, draining a full bathtub with a volume of 200-240 liters may exceed the permissible burst discharge of an Astra 3 septic tank, even if only 1 person lives in the house.

The dimensions of the structures, starting with the Astra 5 septic tank, are designed in 3 height options, depending on the location of the inlet pipe on the station body. The maximum depth of the pipeline when installing the system, taking into account the thickness of the pipe along the bottom wall, is indicated:

• without additional designation - 0.6 m for the Astra 3 septic tank and up to 0.85 m for other models with a body height of 236 cm;
• Midi Unilos - 0.85 m with a body height of 250 cm;
• Long – 1.0 m with a body height of 300 cm.

Unilos septic tanks with forced discharge are marked “pr”. The absence of a designation indicates that it is necessary to equip gravity drainage.

Rules for choosing septic tanks Unilos Astra

The correct operation and performance of the station depend on the number of users (including regularly visiting guests), the type and quantity of plumbing fixtures, the distance to the treatment structure, and the purified liquid discharge system.

The approximate number of plumbing fixtures for some Unilos models is given in the table.

Take extra equipment if there are more points installed in the bathrooms and kitchen, or if you use bulky plumbing fixtures. If you are in doubt about choosing a specific model, seek help from a specialist.

The outlet of the waste line from the building affects the installation location and the height of the Astra station building. It is better to calculate these parameters simultaneously. According to SNiPs, the conductive line is lowered by 2 cm every 1 m of the line.

If the location of the VOC on the site has already been determined, then its modification must be selected depending on the depth of the supply pipe.

The type of soil influences the choice of the Unilos septic tank drainage system. The gravity flow scheme is suitable for sandy soils. For clay and loam with a high groundwater level, forced pumping is necessary.

Which model to choose

When choosing a treatment plant, you should consider important criteria:

• daily volume of waste liquids;
• number of users;
• the number of plumbing units that are used at a time;
• distance from the station to the sewerage facility;
• depth of sewer network outlet;
• method of drainage;
• type of soil (clay, loam, sand or quicksand);
• the need to use a disinfection system.

Installation of a Unilos Astra septic tank and its maintenance

You can install an autonomous sewer system yourself in the manner prescribed by the manufacturer. But the warranty on parts and proper operation of the equipment is valid only when the system is connected by certified specialists.

Expert opinion

Order installation of a septic tank

In the first month, it is necessary to limit the use of dishwasher and washing machine products. This will promote faster development of microflora inside the septic tank.

Maintenance of the station involves removing contaminants from inside the system:

• pumping out excess from the third chamber;
• removing contaminants from the walls of the tank;
• washing the filtration element in the aeration tank - removing stuck hair, wool and other fluff;
• cleaning the compressor air filter.

This work is carried out once a quarter, according to the operating instructions for the Unilos Astra septic tank. Every 5 years, the first settling tank is cleaned of accumulated solid heavy particles. Electrical components and the control unit should preferably be inspected and maintained by electricians-installers.

Note!

In case of self-service, the manufacturer has the right to disclaim warranty obligations.

For self-service, you will need to use a minimal set of tools and these step-by-step instructions:

1. Preparation

Visual inspection of the station: internal parts, electrical components, presence of dirt in all chambers and on parts; as well as preparing rubber gloves, a pumping container and a Phillips screwdriver.

Next, turn off the power supply to the compressor on the main panel (button - Network) and after 20-30 minutes you can begin servicing.

To do this, move the switches to the position:

• "Compr." — “0”
• "Manual" - "1"
• "Return." — “0”

It is recommended to remove sediment from activated sludge inside the settling tank, wash the walls of the secondary settling tank, nozzles, clean the filter and pump from untreated fractions, as well as the air filter and hair trap.

2. Pumping out waste sludge

• Remove the pipe from the mount leading to the standard pump and unscrew the clamp using a screwdriver or socket wrench to remove the plug;

• Lead the edge of the pipe into the container, turn on the network on the control panel (“Comp.” - position “1”). The removal of excess activated sludge will begin;

• Pump out approximately 50% of the sludge mixture from the stabilizer volume;
• Turn off the power and manual mode (“Compr.” - “0”, “Manual” - “0”);

• Return the pipe plug and clamp to their original place, and turn on the compressor.

After completing all maintenance items, fill the station with water in a volume equal to that pumped out.

Note

: A standard mamut pump is not capable of pumping out the entire mass to the bottom, so excess activated sludge should be removed in this way once every 3 months during active operation of the station.

3. Cleaning the coarse filter and the main pump

With the compressor turned off, you need to release the main pump hose from the holding clips and the filter itself (you will need a screwdriver again), then disconnect the hoses and remove the devices from the septic tank. Turn the filter over and pour out the impurities. Place the pump back into the coarse filter and install it in the receiving chamber.

4. Cleaning the secondary settling tank

To do this, the walls of the tank are washed with powerful water pressure, after which the dirty film is caught with a juicer or a scoop. Everything is done with the station de-energized!

5. Cleaning the compressor filter

Unscrew the compressor cover, remove the filter and clean it (it is not necessary to wash or wash it).

6. Removal of secondary contaminants

We are talking about a hair collector, which should also be removed from the aeration tank and thoroughly rinsed under powerful water pressure.

7. Pumping out stabilized sludge

The procedure is performed every 3-5 years. And for this you will need to connect a separate fecal or drainage pump, or call a sewer truck if the station is designed for a large number of people.

Pumping is performed chamber by chamber with the compressor power turned off. For example, we pumped out the sludge settling chamber, filled it 50% with water, then proceed to the aeration tank, receiving chamber, etc.

During pumping, it is better to dilute the sludge with water by pouring it into the chamber from a hose to collect all the sludge from the bottom.

Time intervals for replacing components

Manufacturer Unilos Astra recommends:

• every 6 months, clean the filter to catch hair in the aeration tank;
• Change all filters once a year;
• Change all membranes in the compressor once every 2 years;
• Complete replacement of components once every 5 years.

Features of the use and organization of biological treatment systems

Wastewater treatment processes are based on the activity of bacteria. Activated sludge plays the main role here. Its components provide effective biological treatment. If the conditions for the growth, development and nutrition of living organisms are unfavorable, then the quality of purification deteriorates. To prevent such a situation, you must adhere to the rules for using sewer networks and plumbing units.

The following must not be disposed of in the sewer:

1. construction waste, lime, sand, cement and other waste;
2. petroleum products, paints, fuels and lubricants, antifreeze, alkalis, acids, alcohol and other similar substances;
3. materials made of polymers and other substances that do not biodegrade (films from packaging, cigarette filters, contraceptives, hygiene bags, etc.;
4. garden and household waste, fertilizers and other waste;
5. garbage in the form of rotten vegetables, wild mushrooms, washing liquids with disinfectants (active chlorine, ozone, etc.);
6. regeneration (wash) waters from water purification systems, if they contain external oxidizing agents (potassium permanganate);

The release of the above substances causes osmotic shock in the cleansing bacteria. As a result, the quality of cleaning deteriorates sharply. In some cases, the activated sludge dies completely.

What other substances are not advisable to pour into the sewer:

1. A large amount of waste after bleaching clothes (if the substances contain chlorine). These include “Whiteness”, “Persole”, etc.
2. Cleaning preparations with chlorine and antiseptics. This can lead to the death of sludge and loss of system functionality.
3. Medicinal substances.
4. Pet hair in large quantities.

Experts say that using special nozzles with toilet dispensers can also cause system failure. After all, such attachments contain antiseptics.

If the operating rules of the treatment station are fully followed, the purified water has no odor. It is completely transparent.

What can be disposed of in the sewer:

1. soft toilet paper that disintegrates easily;
2. chlorine-free wastewater from washing machines;
3. kitchen drains if non-chlorine detergents are used;
4. bath and shower drains;
5. · a minimum amount of preparations for cleaning plumbing fixtures and household kitchen equipment (no more than once a week).

In order for a treatment plant to function effectively, exposure to chemicals must be avoided. All of them have a negative effect on bacteria. Experts recommend activating biological processes. Users can use detergents, disinfectants and cleaning ingredients that contain biodegradable substances. Washing, cleaning and cleaning should be done at different times. This will prevent the massive release of harmful substances into the purification system.

UNILOS treatment stations are reliable and convenient devices that function properly for many years. Cleaning is controlled automatically. This avoids constant maintenance. The user has minimal responsibilities for system maintenance.

Water purified by UNILOS biological treatment stations of the Astra and “SKOROBEY” series is transparent and odorless. Ice block removed from the aeration tank. Purified water in the upper part, and activated sludge in the lower part

Preservation of the Unilos Astra septic tank

If the station does not receive wastewater for 3 or more months, its conservation is required.

To do this, when preserving “Standard” and “Midi” stations with a capacity of 0.8 m3/day or more, according to the manufacturer’s instructions, you must:

• Carry out maintenance;
• Disconnect the septic tank;
• Remove the compressor from the station and store it in a warm, dry place;
• Completely pump out the sludge stabilizer chamber, then fill it no higher than the level of the supply pipeline (about 1.8 m from the bottom);
• Remove excess activated sludge from the aeration tank to a level of 1.7 m from the bottom;
• Add clean water to the receiving chamber no higher than the point of the supply pipeline (about 1.5 m from the bottom);
• Prepare 2 liters or 5 liters of plastic bottles filled 50% with sand, and place 1-2 in each chamber;
• Insulate the septic tank lid with material that does not absorb moisture and is at least 5 cm thick;
• Cover the perimeter of the station with film and secure it.

For the Long and Astra-3 stations, after pumping sludge from the chambers, the aeration tank, secondary settling tank and sludge stabilizer must be completely filled with clean water to the overflow level, and the equalization tank must be filled to a height of about 1 m.

Important ! After conservation, the septic tank should be completely de-energized, and no more waste should flow into it.

To resume operation of the station after mothballing you will need:

• Remove bottles with sand from all chambers;
• Fill the aeration tank and sludge stabilizer chambers with water to the top level;
• Install the compressor and connect it to the station;
• Connect the septic tank itself to the network.
