Biological maintenance of septic tanks and grease tanks relies on biological products that act on accumulated organic matter, useful in restaurants, rural accommodation, campsites, agri-food operations and sites without a connection to the sewer network. The two products differ in form: water-soluble sachets added to the tank or the toilet, and a powder with a dose calculated according to the volume of the system, also suitable for grease containers in the agri-food industry. In both cases there is an initial seeding dose and a maintenance dose.
Bio Soluble is dosed per 1,000 l with 3 seeding sachets directly into the tank and 1 sachet every 2 weeks in the toilet as maintenance, leaving it to stand for 5-7 minutes before flushing; Bio tank, in powder form, adjusts the seeding dose to the volume of each system and is suitable for both septic tanks and agri-food grease containers. Both have a technical data sheet and a safety data sheet (SDS); Instaquim is the manufacturer.
