For the polymer solutions, it is possible to achieve up to 80 % drag reduction with only a few parts per million of polymer. Ionic and non-ionic surfactants can also offer similar drag reduction as polymer solutions but at a high concentration of few percent. Microbubbles are perhaps the cheapest and non-polluted drag reducer.
