How We Pick Best Laundry Detergent for Septic System 2022
The negative effect on nature is obvious: phosphates completely destroy calcium ions, which leads to the action of active surfactants.
Phosphate-containing substances kill part of the bacteria, reducing the effectiveness of the entire purification system of septic tank. So it is better to avoid this type of cleanser if you are using a septic tank.
Water hardness which is essential for the longevity of the septic tank. The composition of water is also important.
The level of contamination of the object (dishes, linen). Frequency of detergent use is of paramount importance, as the wrong choice of detergent will damage the septic system very quickly.
Phosphate and chlorine-free cleaners can be used in septic tanks, but the increased surfactant content also adversely affects the microenvironment.
So try to choose such products, but watch out for the surfactant content to be less than 5%.

We try to avoid things before choosing best laundry detergent for septic systems 2022:
Pure chlorine, as well as chlorine-containing substances and detergents. Substances and products from surfactant content more than 5%.
Medicines and substances containing formaldehyde, nitrate oxidizing agents and quaternary ammonium compounds.
They are not fatal but can cause a strong and persistent unpleasant odor from the septic tank.
Phosphate and petrochemical-containing liquids (kerosene, gasoline, engine oil, paints, solvents, fuels and lubricants, cadmium.)
Active substances such as alcohols, acids, alkalis, antifreeze, phosphorus compounds, etc. Cleansers with artificial colors, perfumes, fragrance, parabens and sulfates.
How Does Septic System Work?
A septic system is an underground treatment center for wastewater from your kitchen, laundry room, and bathroom.
The bacteria break down the waste and the remaining liquid drains into a drainpipe where the bacteria treat the wastewater before safely releasing it into the ground soil.
The wastewater moves to a central area where it separates the oil and grease that float to the top, and the solids that sink and form sludge.
