Urinary Calculus Removal and Deodorizing - Toilet
Suppression of toilet urinary stones and deodorization and sterilization of ammonia etc. by Mechacera Device
Mechacera device is a deodorizing sterilization and oxidation technology uses a chemical reaction with Mechacera Water obtained by contacting an aqueous solution containing free Chlorine such as Sodium Hypochlorite with a fine Ceramics (ball) incorporating a Fe / Mn / Co-based oxidation catalyst. It is also possible to incorporate a Mechacera device (Cylindrical Can body) into the existing circulating water piping such as a deodorizing device. Mechacera device has a deodorizing effect on the following offensive odor substances.
1) Ammonia (NH₃)
2) Methyl mercaptan (CH₃－SH)
3) Hydrogen sulfide (H₂
6) Methyl disulfide (CH₃－S－S－CH₃)
7) Acetaldehyde (CH₃CHO)
8) Styrene (CH ＝ CH₂)
9) Skatole (C₉H₉N)
It is said that the main component of the unpleasant odor in public toilets is skatole (3 methylindole).
As the structural formula of skatole is represented by (Fig. 2)
Since it has a -NH- functional group, it exhibits weak basicity and reacts with acids to form salts. As shown in equation (1) below, Chlorine molecules (Cl₂
Cl₂ + H₂O → HCl + HClO ・ ・ ・ ・ (1)
2C₉H₉N + HCl → 2C₉H₉N ・ HCl ... (2)
Produces skatole hydrochloride. Amine salts are odorless and soluble in water. Furthermore, the bactericidal action of hypochlorite ions eliminates the unpleasant odor peculiar to public toilets with the initial disinfecting effect.
The application of “Mechacera Water” to toilet drainage focuses on removing the malodor of Ammonia. Urine stones are also processed as part of this. From the viewpoint of chemical reaction, it should be treated in the state before it becomes urinary stone.
Urinary stone contains various components, but most of them are mineral components, especially Silica and Calcium Carbonate. These adhere to the surroundings of the equipment for a long time, give off a foul odor, and become a tan solid deposit. If left in such a state, it will not be easy to remove. It is considered preferable to take measures (cleaning) before that.
Mechacera Ceramics contains 18 kinds of metals and acts as a catalyst in water, promoting the reaction between Sodium Hypochlorite and Water. This reaction formula is as follows.
Fe₂O₃ / TiO₂ (Titanium and Iron, Mechacera Catalyst)
NaCLO＋H₂O → HCLO +NaOH → HCL+1／2O₂+NaOH
[Reaction of Mechacera Water to Urinary Stones]
From the above reaction formula, the HCL produced reacts with Silica / Calcium Carbonate in the Urinary Stone to produce Calcium Chloride and dilute Sulfuric Acid. In this state, it dissolves easily in water, so it is drained without adhering, and it is possible to prevent the formation of solid matter. The reaction between urinary stones and Mechacera Water produces soluble substances, which are then excreted in the water. The reaction formula is as follows.
SiO₂ ＋ CaCO₃ + HCL → CaCL₂ ＋ H₂SO₃
The above reaction formula is shown as a reaction example, and does not mention the molar reaction. SiO2 contains various minerals, and sulfuric acid is taken as an example of the product, taking sulfur content as an example. Both Calcium Chloride and Sulfuric Acid are soluble in water and are treated as wastewater. As an example in the absence of Mechacera water, CaCO₃ reacts with H₂O and CO₂ in water to produce Ca (HC0₃) 2 compounds. Although it is water-soluble, it adheres to and remains in pipes and surrounding substances and scales. The use of Mechacera Water will prevent this reaction.
Although it was made soluble and discharged, it is possible that there is silica or charcoal that remains in the unreacted state. If you do so, it will re-deposit as a foul odor or stain within a long period of time, so it is necessary to properly inject and deal with it when applying Mechacera Water. As the degree of alkalinity increases, urinary stone adhesion is promoted, so it is important to manage the PH value properly.
