Water Videos

This week, we have three videos. The first is a tour of wastewater treatment plant in OK. The second is an information video about land application of biosolids from San Francisco. And the third is about a desalination plant.

  1. Bar Screen? Screening out objects larger than one inch. Does that refer to the female sanitation accessories? Yuck, that's gross!

  2. I do not know why my name came up as Hadas, Christie, and Allison. This is Hadas, and it's probably since they created a wiki with me on my account.

  3. Are we are at risk for Cancer due to the water we are drinking? If water has a small amount of impurity that was not filtered during the process, can that contamination cause harm to people?

  4. Interesting information - guess I should of waited till I finished my lunch before viewing -lol - at least the first two. with my job I have had an opportunity to tour water and wastewater plants - actually I find the processes very interesting and encourage anyone to do so if the opportunity would present itself. I do question the comment made in the first video about the water being cleaner that that in the stream ... I was under the opinion that you cannot put back water that is cleaner than the stream since it too would upset the environment?? Will have to verify this. The videos on biosolids and desalination was most informative - I think we need to be more receptive to recycling waste and encourage its use, animal manure has been used for centuries in the farming industry and other countries have been refining the desalination technology for decades as well - we need to find more ways to recycle and better use our recyclables so we can preserve what resources we have left.

  5. I liked going through the steps in the first video. It seems like an extremely slow process but very effective. Highly treated solid waste= biosolids? It is a relief that San Francisco doesn't use them in their food process. That is disgusting. I liked these videos it was extremely interesting learning about the cycle that the water has to go through to make it healthy, clear, and less of a risk. It is scary to think that clean water is depleting but I'm sure that we will find another water supplement.

  6. Video 1: Let me just say, ew. I am thankful that we have clean water available to us, but I’m better off not having the visual of 4 feet of sludge as I am pouring it into my cup. I assume this is the filtration process that is used locally, since we don’t have salt water available, and I don’t think we use the same filtration processes that San Francisco does. It is fascinating that they treat the water to get rid of the stench, and that the water that is pumped back out into nature is cleaner than the water that was already there. I wonder how that affects the animals. In the same way that you shouldn’t use anti-bacterial soap because it doesn’t give your immune system enough of a workout, I wonder if dirtier water would have adverse affects on fish and other wildlife if they wander outside of the clean water zone.

    Video 2: San Francisco is pretty freaking cool. I know that they are big into localization out there, as people are in many of the bigger cities, so it must be nice for them to receive free compost. It’s a way to give back, although, I’m sure it eases some of the issues that the treatment plants have with getting rid of the leftovers. Crap is crap, but it’s good to think that they are abstractly giving back to the environment somehow.

    Video 3: The main thing that I took away from this video is that community college rules. I got the impression that they are really trying to push that this will be a booming industry in the not too distant future. As we discussed in class, we may need to start using salt water as an alternative, otherwise, what else can we do about our rapidly depleting water supply?

  7. I thought all 3 processes were fascinating, but I have to wonder if its better to return overly filtered water into a stream? I wonder what that does to biodiversity? And when they desalinize water what happens to the salt they remove? Dump it in the enviroment, you are likely to kill something. Just a thought...

  8. I think the techniques that we have come up with to protect against soil corrosion are great. I realy liked the demonstration in video two . I found it very interesting and the next time I hear someone talking about this subject I will at least know what they are talking about. In the third video I would find it annoying to look for bugs and thats probably why I never had a garden but the information was very valuable. As for the last video I dont know how I feel about GE foods. I do feel that we would have more land to farm if people would not feel the need to develop everything. On one end we say we cant produce enough food for all the people but then we develop everything. It appears no land is safe. I try to buy organic whenever I can afford it.

  9. I think that the videos were very interesting. The second video answered a lot of good questions and it was very informative. I kind of did not like the subject but definitely it helped to learn something "behind the scenes," we do not see or know much. It is about recycling and we heard several times that it is very good for land, food production, and the environment. Everything that is done on these three videos is huge for keeping the environment clean. I do not feel like drinking water any more. Drink it or not that is the water we use for everything else: cleaning, cooking,washing,dish-washing,laundry... Certainly, it made me think especially of all the water that is being wasted, like we can never run out the fresh water. But we should be more responsible for one of our most important resources.
