  • im just curious... but is that stringy stuff hair? or something else?

  • The stringy stuff are filamentous bacteria (Thiothrix sp.), if abundant, they cause bulking and problems during the technological process

  • Are they getting paid by the hour to clean the water? If so, the company will go broke... it'll take them forever to clean up 1 cm^3...

  • The first rotifer looked like it was either dead or sleeping, and the second was moving around like it was trapped & frantically trying to escape & couldn't. Wow. Interesting.

  • This video is awesome. I am a process engineer who has recently been asked to take charge of our ETP. It treats coke plant effluent- coke as in coke ovens. Looks like it is in a mess. Can anyone help in training me?

  • @jdlopezh

    sure is, it stacks de flocculated stuff way to high!

  • @ripariaorg Are you a process engineer at a plant?

  • Thank you su much

  • The bacteria in the background is Thiothrix (filamentous sulfur-accumulating bacteria). The bukling was a consequence of nutrient disbalance and lack of oxygen in aeration tank.

  • I'll have to disagree. Filamentous bulking is a pain in the ass.
