Dry toilet for a summer residence without odor and pumping

Which dry toilet is better to use for a summer residence?

Toilets, based on the method of biological processing of human waste, are divided into three types:

• peat (compost);
• liquid (chemical);
• electric (don’t be surprised, there are some, but they have nothing in common with the electric chair).

Peat dry toilets

In these toilets, feces are separated into solid and liquid phases using a peat mixture enriched with special bacteria (the use of regular peat is ineffective due to the insufficient number of microorganisms in it). The solid phase is poured into a compost pit, from where after 2-3 years it can be removed and used as organic fertilizer. The liquid phase is discharged into the drainage network.

Since the decomposition process is accompanied by the release of gas, the lower sealed tank is made with two outlets: one for drainage, the other for connection to the exhaust riser.

Construction of a peat dry closet.

Advantages of peat dry toilets

• simplicity of design (although there are models with an exhaust fan);
• environmental friendliness (no chemicals);
• maintaining and cleaning the compost bin is not difficult;
• low price of the device itself and composting materials (with the exception of a small number of imported products).

Disadvantages of peat dry toilets

• permanent installation due to the presence of a ventilation pipe;
• For “high-performance” modifications, the filled container is quite heavy and is usually equipped with wheels, so you need to think about the route for transporting it to the disposal site.
• large sizes compared to other types of dry closets.

When is it appropriate to use. A peat dry closet is an ideal option for owners of large plots who want to obtain a high level of organic waste processing at low operating costs with the possibility of their further use as fertilizer. The most suitable place for such a toilet is a separate extension or a ready-made factory cabin, which will require additional capital investment.

Liquid dry toilets

Liquid dry closets are devices in which waste is disposed of using special liquids. Water (usually with added flavoring) is poured into the upper tank, and concentrate is poured into the lower container. When flushed, the water mixes with the concentrate and forms a chemical composition that affects the feces.

Construction of a liquid dry closet.

There are two types of liquid dry toilets:

1. Formaldehyde

They block the process of biological decomposition by destroying bacteria that cause stench. Formaldehyde-based composition is very effective in terms of odor removal, but is very toxic. Therefore, under no circumstances should the processed product be buried in the soil, not only on the site, but also outside it. The only method of disposal is to drain it into the central sewer system or hand it over to a service organization (if such a service is available). Because of this problem, formaldehyde-based dry closets are rarely used in suburban settings.

2. Ammonium

They process the “primary product” according to the principle of anaerobic septic tanks, i.e. based on microbiological decomposition in combination with oxygen deficiency. The ammonium-based composition is not as effective as the formaldehyde-based one, but it is much less harmful and can be used to add to a compost pit.

So, an ammonium toilet, like a peat toilet, can be classified as a “waste-free” product. However, waste processed in this way is not ideal from an environmental point of view (they still have some toxicity), so compost can be used no earlier than after 3 years (peat-based compost is ready for use after 1-2 of the year).

Advantages of liquid dry toilets

• light and compact (can be transported in the trunk of a car);
• no ventilation device required;
• tightness and hygiene, which allows the products to be installed even indoors (for example, in a room where a seriously ill patient is located).

Disadvantages of liquid dry toilets

• relatively high operating costs due to expensive concentrates;
• problem with waste disposal.

When is it appropriate to use. Liquid dry closets are attractive due to their mobility: they can be installed anywhere and taken with you outdoors. They are especially good as an individual option, because... for a family of even 3 people, a 12 liter capacity will clearly not be enough (it will have to be changed every 2-3 days), and not everyone can lift a container with a larger capacity.

Electric dry toilets

If you look at it from the point of view of ease of use, then this is the optimal alternative to a country toilet. Human organic matter (all or only its solid fraction) in an electric dry closet is loosened, heated and dried by an air flow forced by a fan. Due to this, the processed mass decreases in volume several times, after which it is composted. The need to use water for flushing depends on the type of toilet (compost or cassette). There are models with a combustion chamber where waste turns into ash, and an even more exotic option with freezing.

Installation of an electric dry closet.

Advantages of electric dry closets

• absolute safety for the environment;
• ease of operation and maintenance;
• no chemicals;
• long interval between tank cleanings.

Disadvantages of electric dry toilets

• high cost (average price is 42-45 thousand rubles);
• the need to ensure a positive temperature, forced ventilation, and in most cases, drainage;
• energy dependence.

When is it appropriate to use. If funds allow and there is a source of electricity, an electric dry closet is the most technologically advanced solution.
In developed countries it is gaining more and more popularity.

Ten best models of dry toilets

10. Separett Camping 1165

An excellent solution for a good outdoor recreation at a considerable distance from the conveniences of civilization, and the arrangement of this toilet will take a minimum of time and effort. This is a rather original design that does not require any water for flushing, and also does not require the additional purchase of consumables such as liquids for breaking down waste. This model is a folding product that is very convenient to transport to any place. The product is produced according to the standard scheme of composting dry closets. Solid and liquid waste are not mixed in it, which allows the product capacity to be significantly higher and prevents the formation of unpleasant odors. The device is absolutely safe for the environment. The set includes a special fabric bag for easy storage and carrying.

It is worth noting that waste is not processed here: liquid waste passes through a special filter element and is discharged into the environment through a hose, while solid waste enters a biodegradable bag. Once it is full, it is removed and thrown into a regular compost pit. The volume of the waste tank is as much as 23 liters, so the bag takes a long time to fill. The seat height is 54.1 cm – quite comfortable for an adult.

Advantages:

• Does not require water or sewerage;
• No need to purchase consumables;
• Absolutely safe for the environment;
• The waste can be used as fertilizer;
• Features excellent capacity;
• Reasonable cost;
• Foldable design.
