Ferric chloride is pretty harmless stuff. It is the copper, tin and 
other metals the enchant eats off broads that are the problem in septic 
tanks. The are the ones toxic to life in relativity low concentrations. 
Sewage unlike soil doesn't have an unbelievable about of surface area on 
the soil particles to bind to copper and mitigate its toxicity and make 
it available in a form life can use it.
