Choosing a dry closet for a summer residence

Dry closets are an alternative to plumbing equipment connected to the sewerage and water supply network.

Mixing with waste, peat with the help of aerobic mineralization turns them into compost, which can later be used as fertilizer. Due to the absorption capacity of peat, you can significantly save on filler – 1 kg of dry mix is ​​enough for about 10 liters of liquid. The tank of such a dry closet is emptied as it fills.

Liquid (chemical) dry closets

A chemical dry closet consists of two combined sections – in the upper there is a water tank, a toilet bowl, a seat and a pump.

Recycling of waste in liquid dry closets is carried out using chemical reagents that break down solid fractions and eliminate unpleasant odors. Before use, water and deodorizing liquid are poured into the upper tank, the lower tank is filled with sanitary liquid.

This type of dry closet is more convenient due to its compactness and ease of use, however, in order to obtain fertilizer at the output, it is necessary to use only natural compounds. There is now a wide variety of live bacteria formulations on the market that convert waste into biological fertilizer.

It can be installed both outdoors and indoors. When choosing the volume of the tank, pay attention to the fact that all fluids are active for about 14 days. In addition, different models of liquid dry closets are equipped with different types of pumps.

Solid fractions are dried at temperatures up to 550 degrees and collected in the form of ash in a container, which is then emptied once a week. Liquid fractions evaporate. At the dacha, such a toilet can be installed only if there is electricity, which is necessary for the operation of the compressor and ventilation.
