Rustdoctor™ Disposal Methods

Since each local water treatment sets their own disposal limits, it is impossible to have one broad disposal method for spent Rustdoctor™. What can be put safely down the drain in one city can cause problems in the next city.

Rustdoctor™ Disposal Characteristics

Rustdoctor™ when spent is very similar to human hair shampoo except it contains lots of iron. It may also contain oils and greases from dirty parts that were cleaned in the Rustdoctor™.

Completely spent Rustdoctor™ contains 5% of its weight in iron. This works out to approximately 54000 ppm of iron. Many waste treatment facilities do not have specs for iron.

Its pH is 7.0 to 7.2. Most disposal specs call for a range of 6.0 to 9.0.

Disposal Options

Rustdoctor™ is easy to dispose of in most areas. After checking with the local waste treatment facility to determine the specs for iron. Most facilities will allow it to be put down the drain.

See HRSD Approval Document

In areas where it cannot be put down the drain there are still several options for disposal.

• Spent Rustdoctor™ can be run through in-house waste treatment systems. The chelator in the product chelates iron only. It releases iron at pH 10 and above.
• The water in spent Rustdoctor™ can be allowed to evaporate, and the residue can be placed in solid waste.
• Small amounts of spent RustDoctor can be diluted with water at a 1 to 10 ratio then applied as a greening agent to lawns and golf courses. The spent product is very similar to chelated iron greening agents commercially available at home improvement stores.
