Can’t connect to a public sewer, but not a fan of septic tanks? Then we suggest you get a small purification device. This device is actually a filter which treats wastewater through biodegradation. In addition to being small in size and therefore ideal for a family house, this device works on a simple principle of mechanical and biological separation and degradation, it’s stable, reliable, and consumes little power. Domestic wastewater purification devices are similar to those used for commercial purposes in that they, more or less, work on the same biochemical principles based on degradation of waste material using oxygen-feeding microorganisms (aerobic devices), or those which don’t need oxygen (anaerobic devices). In other words, there are small aerobic and anaerobic purification devices, small organic purification devices, MMR purification devices, SBR purification devices, FBR purification devices, and continuous purifications devices, and devices combining these technologies for aerobic biological processes, biodegradation of organic substances with activated sludge, membrane technology for removal of most viruses and bacteria in joined or separate wastewater treatment sections. According to the Water Act, these devices are used for sanitary domestic purposes and are not against the public interest, meaning that they can be installed without a permission issued by local authorities. However, since this issue can fall within the competence of several bodies (in charge of environmental protection, protection of water resources, mandatory utilities, and sanitary protection), we recommend you consult your local council or relevant local authorities about applicable regulations to avoid any unpleasant surprises.
