Methods for controlling the fouling potential of macroinvertebrates are provided. An effective controlling amount of a polymer comprising a tannin and a cationic monomer is added to an aqueous system suffering from the fouling potential of macroinvertebrates.

Methods for controlling macroinvertebrates in aqueous systems

The present invention is directed to methods of detoxifying water containing alkylthioalkylamine compounds. The methods comprise adding to an aqueous system containing alkylthioalkylamines, a sufficient quantity of a swelling type natural or synthetic clay to neutralize the toxicity associated with alkylthioalkylamines to aquatic organisms.

Detoxification of alkylthioalkylamines with swelling type natural or

The present invention is directed to a method of detoxifying water containing quaternary ammonium compounds to the extent that aquatic life such as fish and macroinvertebrates are protected. The method comprises adding to an aqueous system including a quaternary ammonium compound a sufficient quantity of a de-oiled lecithin. De-oiled lecithin is a mixture of phosphatides with about 2% or less residual oil.

Methods of detoxifying quaternary ammonium compounds toward aquatic

Detoxification of quaternary ammonium compounds using detoxifying amounts of lignosulfonate.

Detoxification for quaternary ammonium compounds with lignosulfonates

Methods for controlling the fouling potential of Asiatic clams in aqueous systems are provided. The methods comprise adding to the aqueous system an effective controlling amount of a tetraalkyl phosphonium salt compound. The preferred compound is tri-butyltetradecyl phosphonium chloride.
