In particular, the hydrogen peroxide generator [122] is adapted to release hydrogen peroxide within a predefined range of 2 - 30% volume of the storage tank [110], preferably between 3-6 % volume of the storage tank [110]. Notably, the hydrogen peroxide generator [122] generates the hydrogen peroxide by way of an electrolytic chemical reaction. As the hydrogen peroxide generator [122] is positioned within the storage tank [110], the hydrogen peroxide so generated is released in water stored in the storage tank [110] of the flush tank [108].

  • the self-regulated cleaning system [104] by following the self-regulated cleaning method/ process [142] enables automatic cleaning of the toilet bowl [106] of the toilet arrangement [102], a need for separate maintenance staff is avoided and thus the maintenance cost is substantially reduced. Also, timely and scheduled cleaning of the toilet bowl [106] of the toilet arrangement [102] enables increased life cycle of the toilet bowl [106] of the toilet arrangement [102].
  • the hydrogen peroxide generator [122] As the hydrogen peroxide generator [122] is positioned within the storage tank [110], it has a protective shield of the storage tank [110]. Such protection of the hydrogen peroxide generator [122] within the storage tank [110] restricts exposure of the hydrogen peroxide generator [122] to external environment, thereby preventing degradation of electrodes contained therein by reacting with ambient air. This improves work life of the hydrogen peroxide generator [122].
  • hydrogen peroxide is environment-friendly. Particularly, upon degradation of hydrogen peroxide, oxygen and water molecules are produced. Thus, usage of hydrogen peroxide is environment friendly in nature. Therefore, Hydrogen peroxide is a safe antimicrobial agent as per USFDA (United States Food and Drug Administration).
