Single Wall Chemical Storage Systems
Siemens provides single-wall, above ground storage systems for odor control chemical feed.  Tanks are made from rotationally molded, high-density cross-linked polyethylene (HDXLPE) and include an overfill protection gauge "U" vent, filler liner, necessary valving, feed pumps, and controls.

Single wall chemical storage tanks are suitable for the following chemical feeds:

-Nitrate salts 
-Hydrochloric acids 
-Sulfuric acids 
-Sodium hydroxide 
-Sodium hypochlorite 
-Water
-Chemicals of a low corrosivity

Double Wall Chemical Storage Systems
These systems provide leak detection and secondary containment should a leak occur.  Fabricated of HDXLPE,  these systems include leak monitors at critical points, alarms, spill containment and overfill protection (triggering an alarm when the tank becomes 90 percent full).

The double wall chemical storage system is suitable for more volatile chemicals including:

• Mineral acids such as hydrochloric, sulfuric and phosphoric acids
• Alkalies such as sodium hydroxide and sodium hypochlorite 
• Chemical oxidizers such as hydrogen peroxide and sodium chlorite
• Inorganic salt solutions such as ferrous sulfate and ferric chloride

Underground Chemical Storage
These systems are double walled and constructed of fiberglass reinforced plastic (FRP).  Features include an internal and external tank, with 2 inch PVC screened vent to atmosphere and (2) 32 inch manways.  The tank is anchored with two FRP anchor straps attached to a concrete slab or deadman for flotation resistance.

Underground chemical storage tanks are suitable for chemicals such as:

• Nitrate salts 
• Ferrous sulfate and ferric chloride 
• Sodium hydroxide
• Sodium hypochlorite
