    Most remnants of photographic processing solutions are biodegradable and are successfully processed by biological treatment systems with aerobic (oxygen present) processes – typically found in municipal sewage systems. Most municipalities establish an allocated limit on discharge of certain materials. You may want to check your local guidelines before disposal. The byproducts cannot however be processed by anaerobic (oxygen absent) biological treatment systems found in septic systems. It is recommended that you find an off-site disposal facility if your locality is backed by a septic system.
