Read Lemna's case studies and let the facts speak for themselves. Their innovative processes are proven and reliable.
Our client, a little community located on the Penobscot River in southern Maine, recognized the need to retrofit an existing wastewater treatment facility. The original system, consisting of three ponds, was at flow capacity and not capable of handling the required limits for BOD and Total Suspended Solids (TSS).
The state of Indiana invoked ammonia limits of 1.5 mg/l (Summer) and 2.1 mg/l (Winter) on this town of 2,600 residents. The community needed to update its treatment facility, but installing a mechanical treatment plant and removing the existing lagoon would have cost too much and consumed too much power to be suitable for such a small town.
This client, located in the primary tourist area of Arkansas, had an existing wastewater treatment facility. However, this existing facility was experiencing trouble consistently meeting the required effluent parameters. In addition, this community had an interest in providing wastewater treatment for a nearby community.
Our client, the largest french-fry manufacturer in the world, needed to replace an existing (competitor's) insulated gas collection cover that was prone to failure due to migrating solids (grease bergs) that ripped the gas collection membrane. The design of the existing cover made it next to impossible to remove the grease bergs and to repair the damaged cover.
Our client is located five miles Southwest of Durango, CO. The existing facility has a four-lagoon wastewater treatment system. The client was having difficulty meeting BOD and TSS limits and they wanted to eliminate algae growth in the settling lagoon. They were looking for a single, cost-effective solution that would meet their needs.
In 1996, the State of Missouri constructed a two-cell aerated lagoon system in Cameron, MO. The lagoon facility was built to pre-treat the wastewater discharged from two state correctional facilities. The effluent from the pre-treatment lagoons was discharged into the City of Cameron's wastewater collection system, and ultimately conveyed to the city's wastewater treatment plant (WWTP).
This small, rural community in Dodge County, WI was faced with a situation not uncommon with many similar communities, the need to upgrade the wastewater treatment plant in their community.
