It could be a Sani septic tank - a popular option for cottages and country estates.

We will talk about what this manufacturer of septic installations offers to the consumer. Let's look at how its products differ from competing offerings on the market. The article we presented describes the design features and provides recommendations for operation and installation.

Treatment plants from SANI

This enterprise was formed as a structure of the Ekola Research and Production Enterprise, specializing in the design and production of sewage treatment systems for their safe disposal. The range offered by the company includes installations for treating wastewater from various domestic, commercial and industrial facilities.

The manufacturer offers:

• septic tanks for different numbers of users;
• efficient biological treatment plants;
• additional modules for solving individual problems.

The design of the products presented for sale has been carefully calculated and tested through many years of practical use. Here you can order the design of an autonomous sewerage system with a treatment plant, its installation and maintenance.All models of septic tanks and VOCs have been certified.

These are durable and relatively inexpensive devices capable of high-quality preparation of wastewater for disposal into the ground or for dumping onto the terrain. The simple design guarantees a minimum of breakdowns and virtually trouble-free operation; installation can be completed in a short time.

The products of this brand are very diverse. Find something suitable device for a small dacha, and for a spacious cottage. A number of proposals will be of interest to owners of various enterprises: cafes, mini-hotels, recreation centers, gas stations, etc.

When choosing the appropriate option, it is necessary to take into account the advantages and disadvantages, installation and operation features, as well as reviews from owners who have managed to gain real experience in operation.

The best choice for a summer residence

SANI-S septic tanks are simple devices that are suitable for servicing small buildings: dachas, cottages, country houses. They are designed to serve less than 15 people.

The buyer is offered a choice of five models of different sizes:

• S-1 1.35 cc m for 1-3 people;
• S-2 2.25 cc m for 4-5 people;
• S-3 3.6 cu. m for 6-8 people;
• S-4 4.8 cu. m for 9-11 people;
• S-5 6.75 cc m for 12-15; people.

The three-section treatment plant is equipped with a built-in drainage compartment. It does not require power to operate, which is an attractive quality for owners of summer cottages and seasonal homes. Made of durable plastic, it is therefore lightweight, making it easy to transport.

The SANI-S septic tank is designed simply and reliably. It does not take up much space, the presence of built-in drainage greatly simplifies installation work

The first chamber is designed to settle collected household waste.Simultaneously with the precipitation of solid insoluble sediment to the bottom, the light organic suspension is processed by anaerobic bacteria.

In the second section, settling continues. Then the purified wastewater enters the drainage compartment, after which it moves through the filtration field into the ground.

The trench for the sewer pipe leading to and from the treatment plant should have a slight slope and lie below the ground freezing level

To install the device, it is necessary to dig a pit and add a layer of sand and crushed stone, which will become an additional filter when draining nearby precipitation into the ground. Trench under sewer pipe should have a slope of about 20 mm per meter.

Deep biological processing plants

The manufacturer offers three types of treatment plants, which differ mainly in size and performance: SANI-5, SANI-8 and SANI-15. These devices have a similar configuration.

They look like a cylinder with a neck, a lid and a conical bottom. There are two pipes on the sides: for connecting sewer pipes. Through one of them, wastewater enters the treatment plant, through the second it moves after processing to the filtration field, infiltrator, absorption well or a drain.

General design features

This type of treatment facility is a non-volatile type of sewerage equipment. The design includes a compressor that pumps air into the device. Not only anaerobic, but also aerobic bacteria can be used in waste processing.

As a result of the involvement of aerobes in the processing process, the cleaning efficiency reaches 98%. This water is suitable for various technical needs.

The body of the Sani-5 type treatment plant is made of reinforced plastic. The lower container and the upper part with the lid are connected by anchor bolts, which must be tightened evenly and consistently

First, the waste is processed in an aeration tank. In the second compartment cleaning with bacteria continues, and sedimentation and separation of contaminants also occurs. The result is almost pure process water, as well as neutral sludge, which can become a fertilizer. The purified liquid is transported into the ground by gravity.

If the groundwater level is high, forced pumping of liquid is organized using sewage pump. In addition, the device can be supplemented with an excess neck, which allows you to increase the depth of the pit for the installation of VOCs. The kit also includes a set of tools necessary for connection compressor.

The cost of VOCs is relatively low, depends on the characteristics of a particular model and starts from 80,800 rubles. The manufacturer assures that the service life of the device reaches 80 years, and the costs of purchase, transportation and installation are recouped in the first year of operation.

Wastewater aeration significantly improves the quality of waste processing and water purification. The compressor in the local treatment plant SANI-5,8 and 15 must work constantly

Features of different models

When choosing a suitable treatment facility, you should pay attention to the characteristics of individual models:

• SANI-5 is designed for a family of five people who use two sinks, one shower and one toilet, with a one-time waste discharge of 500 liters;
• SANI-8 is designed for a family of eight people who use one bath, one automatic washing machine, two sinks, one shower and one toilet, a one-time waste discharge of 800 liters;
• SANI-15 is designed for a group of ten residents who use one bath, one automatic washing machine, three sinks, one shower and two toilets, with a one-time waste discharge of 1500 liters.

A device with suitable performance can be used to service a cafe, mini-hotel or other similar enterprise where there is no access to a centralized sewerage system.

To increase the installation depth of LOS SANI, use an extension neck or two such modules when you need to install the station especially deeply

In addition to the standard equipment, the manufacturer offers a pump, as well as one or two extension necks.

Options with addition are marked as follows:

• Long - one excess neck;
• Super Long - two necks of excess;
• PR - pump for forced pumping.

Each VOC SANI model comes in six variants: standard, Long, Super Long, standard+PR, Long+PR, Super Long+PR.

A few words about installation

To install the VOC, you will need to allocate an area of ​​four square meters (two by two meters). A parking lot can be built on top to make optimal use of this area. The body is made of reinforced plastic designed to withstand high mechanical loads.

The plastic body is not too heavy, but the use of special equipment for digging a pit and moving equipment will significantly speed up the work

For installation, in addition to the pit, it is necessary to construct a trench for the sewer pipe and an absorption well.Do not place VOCs too close to the house, fence, source of clean water and other stationary objects. At the end of the work, only a hatch with a diameter of 800 mm will remain outside.

After the treatment station is installed in the pit, its position is adjusted using a level. As the soil is filled, the position of the device should be monitored.

The VOC body must be placed in a pit, leveled and gradually covered with soil, while simultaneously filling with water to compensate for the pressure. When the backfill reaches the appropriate level, connect the pipes to the inlet and outlet pipes.

At the same time, they install the compressor, connect the hose to the air duct, provide power, and then continue filling.

Backfilling of the housing installed in the pit must be carried out with simultaneous and gradual filling with water in approximately three to four stages. If this requirement is neglected, the device that is not filled with liquid may become dislodged or cracked.

The plastic case weighs little, all work can be done with one or two assistants, there are no restrictions on the time of year. Installation is carried out within one working day, all operations will take about 12-13 hours.

Non-core sewerage equipment

If the usual VOC-5, 8 or 15 is not enough to ensure high-quality waste treatment, an additional treatment station can be used.

Installation to optimize cleaning

The SANI-BF sewerage station is installed below the local station and in front of filtration field. Purified water enters here through the inlet pipe and passes through the sorbent, which is placed in a bag.

Thus, the wastewater is cleared of previously unprocessed organic inclusions.Then additional disinfection is performed using a UV sterilizer, where the liquid is pumped forcibly. Ultraviolet treatment destroys dangerous microorganisms. This water can be used to safely water plants.

The station's capacity is two and a half cubic meters per day. If the distance between the additional module and the VOC exceeds 15 m, an intermediate inspection well must be installed. The optimal distance is up to two meters.

A reinforced concrete slab is laid at the bottom of the pit under the additional station. The body is secured with anchor bolts. The area of ​​the filtration field must be at least 36 square meters. m.

Products for storm drainage installations

Where there are problems with watering the territory, the SANI-L storm drainage station will come in handy. This is a kit for installing a system that allows you to collect surface and melt water. Timely collection and removal of precipitation will prevent flooding of foundations, basements, parking lots, entrances and other similar objects.

The relatively inexpensive modern device SANI-L is designed to collect surface water, as well as purify it from sand and organic matter. This unit is easy to install and operate.

To maintain SANI-L, you will need to periodically wash and clean the main elements from accumulated contaminants. The manufacturer offers three models, the productivity of which varies between 2-8 l/s, and the collection area can range from 0.2 to 1 hectare.

Efficient grease trap SANI-G

Catering establishments will find the SANI-G grease trap useful. The device is designed to collect greasy inclusions before transporting wastewater into the sewer system.This reliably protects the pipes and reduces the likelihood of complex blockages.

The grease trap can be placed in the basement or utility room. The device is selected based on productivity, which is 1-10 l/s. The reinforced fiberglass body withstands loads and contact with hot contaminants, for example, coming from a restaurant sink.

Advantages, disadvantages, tips

Among the positive characteristics, owners of VOCs and septic tanks say:

• simple design;
• almost complete absence of breakdowns;
• inexpensive maintenance;
• the ability to perform installation yourself;
• reasonable price.

Disadvantages include the dependence of VOC on the availability of electricity, as well as the unreliability of the compressor. After several years of use, the device will have to be replaced.

Lack of aeration will negatively affect the quality of processing. Some people note that the sound from the compressor is too loud. But if the VOC is located far enough from the house, the noise will not affect the quality of life.

A durable polymer hatch reliably cuts off unpleasant odors typical of sewage systems. After installation, it should remain on the surface flush with the ground.

Reviews regarding SANI products vary. Many praise the work of treatment stations and septic tanks, while others are disappointed. The cause of dissatisfaction is often high expectations, incorrect installation, or errors in choosing the right equipment.

To ensure that wastewater treatment plants work properly, it is recommended to follow these simple rules:

• do not exceed salvo discharge volumes recommended by the manufacturer for a specific model;
• conserve the system if it will not be used for a week or longer;
• ensure that the temperature of the wastewater is high enough for microorganisms to work effectively;
• do not allow waste that is harmful to bacteria to be disposed of in a VOC or septic tank, for example, containing chlorine, formaldehyde, concentrated acids, alkalis, solvents, and other aggressive chemicals.

In order for wastewater treatment to be of high quality, you need to constantly monitor the situation. For example, if there is no hot water in the house, the wastewater will cool down and the recycling process will slow down. About once a year you need to pump out the contents of the septic tank and flush out VOCs.

When choosing a model, it is better to give preference to a container with some reserve volume. The family may become larger, and the device will have to cope with the increased load. In such a situation, the additional volume will eliminate the need to replace the device with a more productive option.
