PROCESS FOR REMOVING TOXICANTS FROM AQUEOUS PETROLEUM WASTE STREAMS

摘要

Specific toxicants are selectively removed from aqueous waste streams associated with the production of petroleum and petroleum products by contacting such aqueous waste streams with a non-ionic macroreticular polymeric resin having a low to intermediate surface polarity. The toxicants are a group of structurally-related organic molecules containing at least one carboxylic acid group and having a molecular weight in the range of about 200 to about 400. These molecules are toxic to certain indicator species of fish at concentrations of less than 10 parts per billion.
