F� He showed photos of how they reused a facility in Florida. He explained how raw waste goes to treatment, to aeration tank (for every gallon that goes in, one comes out of pipe), solids circulate around tank, is aerated, enters into the back, and settles to the bottom. They propose to have a concrete structure. And they will have some of the equipment manufactured here. They plan to progress on a turn -key basis so other contractors can provide bids separately. United has perfected systems to reduce energy, amount of manpower, and reduce requirements to do work. LEMNA, USA, Inc. - Steven M. Vogel, President/CEO There are two separate corporations. They have eighty offices He thanked Mr. Evans and the Utilities Commission for their efforts. He also thanked the City Council and Commission for their visit of site in Nevada. LEMNA is a duckweed system. They received the 1995 Engineering Excellence award. The Tennessee plant is similar to the one projected for Colton. Mark Adelson, of the Regional Water Quality Control Board, affirmed the statement that it would meet Colton's ammonia limits. Mr. Vogel referred to the booklet materials that were handed out. Their Arkansas plant is at 3mgd (close to what the City needs) and he gave an overview of plant in Louisiana which is operated with 4hp. Mr. Vogel's closing points were that it has the lowest capital cost, is more efficient, has lowest operational cost - the same number of people will easily take care it, has lowest energy cost, and lowest guaranteed project cost. Dave McAnaney, P.E., Director of Technical Sales Support stated he has all the technical data and he will provide it. There was some discussion about the ponds and capacity increase. Benefits of the LEMNA system are that it has better cost for additional flow, improved operating efficiency, and it is a simple operation. He reviewed the benefits of the system as summarized in their packet. Their bottom line figure is $2.826M. It was affirmed that they have had some learning experiences due to the innovativeness of the process. They have had to learn to deal with hot air and other various climates. The systems are now working very well. For this area, it was also noted that there is native duckweed so it is not hard to come by. There are five different duckweed species. Some will rise or thin out according to temperature and disease. In winter it takes little to no harvesting, and more in the two to three hottest months of the year. Recommended disposal is to haul it to a nearby composting plant. Montgomery -Watson - Roger V. Stephenson, Ph.D., P.E., Principal Engineer Mr. Stephenson explained their objectives with the process, its application, capability, and advantages. Some of the detailed matters discussed included: traditional oxidation ditch processes; characteristics of 24-hour hydraulic detention time; and use of brush or surf turbine aerators. 3 NOV 16 1995
