There are some important things about purification plants that www.mcseptics.ca wants you to know if you truly want to have a healthy and clean home.
Put the water in the toilet, pull the tub plug and the dirty water disappears from the house. Through the long underground sewer, it goes directly to the WWTP. Amazing is the way the brown liquid turns into clear water again. And from there it can flow into rivers and seas. The purified water ends its cycle. TPV maintains the amount of usable water, i.e. it does not decrease, thus preventing contaminating and providing eco-balance.
Wastewater is cleaned in two phases – mechanical and biochemical.
In the case of mechanical treatment, larger waste is separated by a grate. There are not only faeces, but also rubbish and food residues that are thrown into the toilet and the sink. The waste water then falls into the grease channel where all the garbage is removed. Water continues its way into the sandy chute where sand and gravel are removed. The mechanical phase ends.
Now comes the biochemical treatment, which is the core of the work of the treatment plant. In the recovery pool, special and beneficial bacteria ensure that the extra substances are broken down.
Because some bacteria need oxygen, there is a periodic influx of powerful air jets into the pool that begins to bubble. Next, separation of water from the sludge follows. At this stage purified water and sludge are examined. If the parameters are the norm, the water is poured into adjacent streams, rivers and lakes.
What happens to the purified silt?
There are more opportunities here. The sludge containing no drug residues is, for example, as a fertilizer in agriculture. In some sewage plants, sludge is burned, but phosphate is lost, which is a valuable nutrient in agriculture. At other stations the sludge is collected in a bioreactor. It produces gas that serves to generate electricity. In addition, humic soil can be obtained from the purified sludge by the so-called grounding.
In rural areas, a population of between a thousand and five thousand people uses one treatment plant. Today most water bodies have good water quality.
What should NOT be poured into the channel?
Hygienic materials should be placed in the garbage can and not in the toilet. The same applies to food residues, as well as paints, varnishes, oils and fats. The chemicals in the medicines further charge the waste water.
Can the purified water be drunk?
This water is not suitable for drinking, even if the degradation factor is 99%. Purified water actually looks clean but has bacteria. There are purification stations that further purify with ultraviolet rays. They disinfect the water and kill the microorganisms. This water has almost the qualities of drinking.
