The need to constantly pump out the contents, as well as the danger of contamination of the surrounding soil, prompt the site owners to look for another solution. It may be the septic tank Sani - a popular option for summer cottages and suburban estates.

We will talk about what this manufacturer of septic plants offers to the consumer. We will analyze how its products differ from competing offers in the market. The article presented by us describes the design features, gives recommendations for operation and installation.

SANI treatment plants

This company was established as a structure of NPP Ekola, specializing in the design and manufacture of sewage treatment systems for their safe disposal. The assortment offered by the company has installations for the treatment of effluents of various domestic, commercial and industrial facilities.

The manufacturer offers:

  • septic tanks for a different number of users;
  • effective biological treatment plants;
  • additional modules for solving individual tasks.

The design of the products presented for sale has been carefully calculated and verified by many years of practical application. Here you can order the design of autonomous sewage with a sewage treatment plant, its installation and maintenance. All septic tank and VOC models are certified.

These are durable and relatively inexpensive devices that can qualitatively prepare wastewater for disposal in the ground or for dumping on relief. A 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. There will be a suitable device and for a small cottage, and for a spacious cottage.A number of proposals will be interesting to owners of various enterprises: cafes, mini-hotels, recreation centers, gas stations, etc.

Choosing the appropriate option, it is necessary to take into account the advantages and disadvantages, especially the installation and operation, as well as the feedback of the owners who managed to get 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: cottages, cottages, country houses. They are designed to serve less than 15 people.

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

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

The three-section wastewater treatment plant is equipped with an integrated drainage compartment. It does not require power supply for its work, which is an attractive quality for owners of summer cottages and seasonal houses. Made of durable plastic, therefore, it is lightweight, facilitating transportation.

Scheme of the septic tank SANI-S
The SANI-S Septic tank is simple and reliable. It does not take up much space, the presence of built-in drainage greatly simplifies installation work

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

In the second compartment, assertion continues. Then, the treated wastewater enters the drainage compartment, after which it moves into the soil through the filtration field.

Trench for the sewer pipe VOC SANI
The trench for the sewer pipe leading to and from the sewage 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, pour a layer of sand and gravel, which will become an additional filter when draining nearby precipitation into the soil. 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 capacity: 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. Two pipes are arranged on the sides: for connecting sewer pipes. According to one of them, the effluent enters the treatment plant, the second moves after processing in the filtration field, an infiltrator, absorbing well or gutter.

General design features

This type of treatment plant belongs to the non-volatile type of sewage equipment. The design provides a compressor forcing air into the device. In the processing of waste, not only anaerobic, but also aerobic bacteria can be used.

As a result of using aerobes in the processing process, the cleaning efficiency reaches 98%. Such 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 sequentially

First, the waste is recycled in an aeration tank. In the second compartment bacteria cleaning continues, and also settling and stratification of pollution occurs. The result is almost pure process water, as well as neutral sludge, it can become fertilizer. The movement of the purified liquid into the soil is carried out by gravity.

With an increased level of groundwater, 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, it depends on the characteristics of a particular model and starts at 80,800 rubles. The manufacturer assures that the service life of the device reaches 80 years, and the costs of the acquisition, transportation and installation pay off in the first year of operation.

 VOC SANI aeration
Wastewater aeration significantly improves the quality of waste treatment and water treatment. The compressor in the local sewage treatment plant SANI-5.8 and 15 should work continuously

Features of different models

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

  • SANI-5 is intended for a family of five people who use two sinks, one shower and one toilet bowl, a one-time waste dump - 500 liters;
  • SANI-8 is intended for a family of eight people who use one bathtub, one automatic washing machine, two sinks, one shower and one toilet bowl, a one-time waste dump - 800 liters;
  • SANI-15 is designed for a group of ten residents who use one bath, one automatic washing machine, three washers, one shower and two toilets, a one-time waste discharge of 1,500 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 sewage system.

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

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

Options with additions are marked as follows:

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

Each SANI VOC model is available in six versions: standard, Long, Super Long, standard + PR, Long + PR, Super Long + PR.

A few words about the installation

To install VOCs, you will need to allocate a plot of four square meters (two by two meters). Parking can be made from above to optimally use this area. The case is made of reinforced plastic, designed for high mechanical loads.

Mounting VOC SANI
The plastic case 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 arrange a trench for the sewer pipe and an absorbing well. Do not place VOCs too close to the house, the fence, the source of clean water and other stationary objects. At the end of the work, only the hatch with a diameter of 800 mm will remain outside.

Installing SANI VOCs by level
After the treatment plant is installed in the pit, its position is adjusted using the level. As you backfill, you should monitor the position of the device

The VOC body must be put into the pit, leveled and gradually sprinkled with soil, while filling with water to compensate for the pressure. When the backfill reaches an appropriate level, connect the pipes to the inlet and outlet pipes.

At the same time, they mount the compressor, connect the hose to the air duct, provide power, then continue dumping.

Spraying the VOC SANI body
The filling of the hull installed in the pit must be performed with simultaneous and gradual filling with water in approximately three to four stages. If this requirement is neglected, the non-liquid filled device may displace or crack.

The plastic case weighs a little, all work can be done with one or two helpers, 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 sewer equipment

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

Installation to optimize cleaning

SANI-BF sewer station is installed below the local station and before filtration field. The purified water flows here through the inlet pipe and passes through the sorbent, which is laid in a bag.

Thus, the effluents are cleaned of previously not processed organic inclusions. Then, an additional disinfection is performed using a UV sterilizer, where the liquid is pumped by force. UV treatment destroys dangerous microorganisms. Such water can be used for safe watering of plants.

The productivity of the station is two and a half cubic meters per day. If the distance between the option module and VOC exceeds 15 m, an intermediate manhole is required. The optimal gap is up to two meters.

At the bottom of the pit under an additional station, a reinforced concrete slab is laid. The housing is attached with anchor bolts. The area of ​​the filtration field should be at least 36 square meters. m

Products for storm sewer

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

SANI L storm sewer scheme
The relatively inexpensive modern SANI-L device is designed to collect surface water, as well as clean them from sand and organic impurities. This installation is easy to install and operate.

Serving SANI-L will require periodic flushing and cleaning of 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 be from 0.2 to 1 hectare.

Effective grease trap SANI-G

SANI-G grease traps come in handy for catering establishments. The device is designed to collect greasy inclusions before transporting sewage to the sewer system. This protects the pipes reliably and reduces the possibility of complex blockages.

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

Advantages, disadvantages, tips

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

  • simple construction;
  • almost complete absence of breakdowns;
  • inexpensive service;
  • an opportunity to carry out installation independently;
  • reasonable price.

The disadvantages include the dependence of VOCs on the availability of electricity, as well as the unreliability of the compressor. After several years of operation, the device will have to be replaced.

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

The durable polymer sunroof reliably cuts off unpleasant odors characteristic of the sewage system. After installation, it should remain flat on the ground.

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

To ensure that the treatment plant works properly, it is recommended that the following simple rules be followed:

  • Do not exceed the volley discharge volumes recommended by the manufacturer for a specific model;
  • carry out conservation of the system if it will not be used for a week or longer;
  • ensure that the temperature of the effluent is high enough for the efficient operation of microorganisms;
  • do not allow the disposal in VOCs or septic tanks of waste that is harmful to bacteria, for example, containing chlorine, formaldehyde, concentrates of acids, alkalis, solvents, and other aggressive chemicals.

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 drains will cool down, the processing process will slow down. About once a year, it is necessary to pump out the contents of the septic tank, flushing the VOCs.

When choosing a model, it is better to give preference to capacity with a certain supply of volume. The family can become larger, the device will have to cope with the increased load. In this situation, the extra volume will save you from replacing the device with a more productive option.

    The manufacturer of these septic tanks greatly embellishes reality. There are no miracles with 98% water purification by household septic tanks, and you should immediately be suspicious of a company that promises this. Also with regard to the service life as much as 80 years. In fact, this septic tank consists of two halves of a fiberglass product, bolted through a sealant. I have questions not only about strength, but also about the tightness of such a design.

    • Expert
      Nikolay Fedorenko

      Good afternoon, Alex! I do not want to protect the manufacturer, but in fairness, I will say that he promises 98% cleaning only when installing the entire system. In addition to the septic tank itself, the system includes:

      - SANI-D - drainage for the removal of groundwater so that they do not mix with sewage;
      - SANI-BF - station for additional sewage treatment with a sterilizer.

      In this case, all components of the cleaning system must be selected for performance. Only in this case, the wastewater treatment will be complete and will make the promised 98%.

      Regarding the issue of tightness: all tanks in the SANI water treatment system are made of solid fiberglass and have no seams. This ensures absolute tightness. If you suspect that the septic tank is not tight, then, most likely, the inlet pipe, neck will be damaged.
