Various types of clusters are collected in the sewerage capacity of a septic tank. During pumping, filters and pumps can easily remove earth and stones, so the main difficulties are caused by liquid contamination. In private homes, septic tanks are now cleaned with special bacteria that easily tolerate the effects of household chemicals, which are also present in drains. Chlorine, soap solution and other household “antiseptics” cannot harm them, but even the strongest formations of contaminants can be easily decomposed by bacteria.
Chemical methods for cleaning septic tanks harm the sewer elements of metal and plastic. Biological filters drain much softer. The integrity of the walls during their operation is not violated, the working parts remain unchanged. It is possible to use industrial water from a septic tank without settling if microorganisms are used. Such water will not harm plants in the soil. Its properties become similar to the properties of natural fertilizers.
In use, bacteria are extremely convenient. They do not require any additional resources, electrical energy and time investment. The required number of spores should simply be launched into the septic tank.
However, certain disadvantages of this cleaning option are also present. In particular, they respond to temperature changes. Active synthetic substances and low temperatures are ways to kill living organisms. In addition, bacteria are sometimes quite expensive. The price of them depends on the purpose and type. In any case, chemicals are much cheaper. For urgent cleaning, bioactivators can also not be used. Bacteria offered in sanitary ware stores most often clean a certain amount of water in a certain time. It's about weeks or even months. They are not suitable for quick cleaning of a septic tank.
There are several types of bacteria for cleaning. They are classified by form and type of action. They can be aerobic or anaerobic. The first to work requires oxygen. Only in the presence of air can they live and have a beneficial effect. Since air rarely enters the septic tank in a natural way, you will also need to purchase a compressor to fill it with air. Aerobic bacteria not only cleanse water, but also saturate it with oxygen molecules. Anaerobic bacteria work without oxygen. Most waste rots when exposed. Heavy sediments can be cleaned from the bottom of the septic tank after exposure to such microorganisms.
