We installed duck bill check valves in our 6 inch gravity lines from the landfill cells and we believe they are restricting flow to the collection point. We will be pulling these out soon to see their condition. There is a possibility that they've inverted further restricting the flow. If that...
We are expanding our landfill, which currently has a gravity leachate removal system. We've experienced some problems with gravity removal and are investigating this. We may opt for pumping, either downslope submersible pumps or stationary with suction hose in the future cells. Does anyone have...
Thanks for the comments. There is no sewer available at the site; we were previously hauling leachate to the sewer plant/lift stations about 25 miles away. We are concerned with TDS, Chlorides, Nitrate and metals to drinking water standards. We have authorization to discharge to percolation...
We are looking at various leachate pretreatment (before RO) systems including US Filter or Zenon's ZeeWeed membrane bioreactor for our landfill. If anyone has experience in these types of systems-pros and cons on operations, maintenance, performance, costs, etc., I would like to hear about it...
I'm sorry I can't help with your question but thought you might be able to help me with some basic calculations on estimating drawdown and storage volume needed for a dewatering operation we are proposing to excavate a stormwater pond. Although I am an engineer, I haven't done much design work...
