WASTEWATER TANK STORAGE TREATMENT
A method and composition for treating a wastewater storage tank during non-use. The method comprises adding a storage deodorant composition to a wastewater storage tank, the storage deodorant composition comprising an odor control agent, a detergent, a surface active agent, and a lubricant; and leaving the storage composition in the wastewater storage tank for a period of 1 day to 12 months.
1 . A method for treating a wastewater storage tank during a period of non-use, the method comprising:
(a) adding a storage deodorant composition to a wastewater storage tank, the storage deodorant composition comprising an odor control agent, a detergent, a surface active agent, and a lubricant; and
(b) leaving the storage composition in the wastewater storage tank for the period of non-use.
2 . The method according to claim 1 , wherein leaving the storage composition in the wastewater storage tank includes leaving the storage composition in the wastewater storage tank for at least about one day.
3 . The method according to claim 2 , wherein leaving the storage composition in the wastewater storage tank includes leaving the storage composition in the wastewater storage tank for no longer than 12 months.
4 . The method according to claim 1 , wherein the composition is added to a wastewater storage tank selected from the group consisting of black water and gray water RV holding tanks, totes, marine and boat holding tanks, aircraft lavatory holding tanks and portable toilet holding.
5 . The method according to claim 1 , further comprising flushing an empty wastewater storage tank with a liquid prior to adding the storage deodorant composition.
6 . The method according to claim 1 , wherein adding the storage deodorant composition comprises adding the storage deodorant composition to a wastewater storage tank containing antifreeze solution.
7 . The method of claim 1 , wherein the amount of the odor control agent is about 0.1% to about 5.0 wt %, the amount of detergent is about 1.0 to about 5.0 wt %, the amount of surface active agent is about 0.1% to about 2.0 wt % and the amount of lubricant is about 0.05% to about 2.0 wt %.
8 . The method of claim 1 , wherein the odor control agent comprises a biocide.
9 . The method of claim 1 , wherein adding a storage deodorant composition comprises adding a lubricant having at least one polymer compatible with an antifreeze agent, wherein the polymer is selected from the group consisting of polysiloxanes, alkylene oxides, phosphate esters, silicone glycols, and combinations thereof.
10 . The method of claim 1 , wherein adding a storage deodorant composition includes adding a storage deodorant composition that is compatible with antifreeze agents.
11 . A method for treating a wastewater storage tank during non-use, the method comprising:
(b) adding a solution comprising antifreeze to the wastewater tank;
(b) adding a storage deodorant composition to the wastewater storage tank, the storage deodorant composition comprising an odor control agent, a detergent, a surface active agent, and a lubricant; and
(c) leaving the storage deodorant composition in the wastewater storage tank for a period of non-use.
12 . The method of claim 11 , wherein the period of non-use is at least about one day.
13 . The method of claim 11 , wherein the period of non-use is between about one day and about 12 months.
14 . The method of claim 11 , wherein the amount of the odor control agent is about 0.1% to about 5.0 wt %, the amount of detergent is about 1.0 to about 5.0 wt %, the amount of surface active agent is about 0.1% to about 2.0 wt % and the amount of lubricant is about 0.05% to about 2.0 wt %.
15 . The method of claim 11 , wherein the odor control agent comprises a biocide.
