Abstract:
An apparatus for cleaning waste water pipes and/or grease traps containing fatty residues and/or grease, said apparatus comprising:apparatus configured to provide a dry agent comprising bacteria and enzymes; apparatus configured to mix said dry agent comprising bacteria and enzymes with an amount of water sufficient to cause in-situ production of an aqueous mixture; an activator vessel structure configured to maintain said aqueous mixture to activate said aqueous mixture for a time sufficient to form an aqueous solvent for cleaning fatty residues and/or grease; apparatus configured to contact said waste water pipes and/or grease traps containing fatty residues and/or grease with said aqueous solvent for dissolving said fatty residues and/or grease; and thus clean said waste water pipes and/or grease traps by biodigesting fatty residues and/or grease deposited in said waste water pipes and/or grease traps; a data processor device operatively connected at least to said activator vessel structure; said data processor device being configured to provide process control; apparatus configured to measure the filling times to fill said activator vessel structure to supply said data processor device with data for process control by said data processor device; apparatus configured to measure the activation period of time of said aqueous mixture in said activator vessel structure for process control by said data processor device; apparatus configured to determine a value of the quantity of fatty residue present in waste water for process control by said data processor device; said data processor device comprising a RAM programmed control apparatus for consideration of days of operation and rest; a storage container being configured to store dry agent; said storage container being operatively connected to said activator vessel structure; a dosage apparatus being disposed beneath said storage container; said dosage apparatus being configured to perform one of: linearly operating mode and circularly operating mode; and said dosage apparatus being configured to supply a predetermined quantity of said dry agent to said activator vessel structure.
