Graphic animations for ECO₂.

How the Speece Cone® works, made for ECO₂ Technologies. An animated film in 4:5 for the LinkedIn and Instagram feeds, with no sound.

An animated film in 4:5 for social feeds, with no sound. It opens on the words How the Speece Cone® works: what happens inside, in 20 seconds. A cross-section of the cone follows. Water from the side-stream pump and pure oxygen enter at the top. The cone widens, so the water slows down. The bubbles are held until they dissolve. The oxygen-rich water leaves bubble-free, with no chemicals added. The cone is stainless steel with no moving parts. Then hydrogen sulfide in sewer force mains before and after, 145 to 0.4 ppm. Why operators switch: 20 to 50% lower operating cost than odor-control chemicals, 34 million lbs of oxygen dissolved every year by ECO₂ systems and 40,000 lbs of oxygen a day into Savannah Harbor. It ends on the ECO₂ logo. The figures are ECO₂'s own field results, published at eco2tech.com.

The ECO₂ Superoxygenation system, made for ECO₂ Technologies. An animated film with no sound.

An animated film with no sound, in ECO₂'s colors and font. It opens on the words The ECO₂ Superoxygenation system: from oxygen supply to an odor-free sewer, in about a minute. First the problem: hydrogen sulfide forming in a sewer force main, 145 ppm of H₂S on average untreated. Then the system builds up over the force main one numbered step at a time: 1, the side-stream pump. 2, the oxygen supply, from an on-site oxygen generator or liquid oxygen deliveries. 3, the automated flow controls. 4, inside the Speece Cone®. 5, back into the main. The result: H₂S before and after, 145 to 0.4 ppm. Why operators switch: 20 to 50% lower operating cost, no chemical deliveries or storage and no increase in sludge, with systems in service since 2003. It ends on the ECO₂ logo: Home of the Speece Cone®, eco2tech.com. The figures are ECO₂'s own, from eco2tech.com.

Breathing life into lakes, made for ECO₂ Technologies. An animated film with no sound.

An animated film with no sound: a lake in cross-section. It opens on the words ECO₂ Lakes & Reservoirs. Breathing life into lakes: how deep-water oxygenation restores a lake without mixing it. Warm surface water sits on cold water and the layers don't mix, so oxygen can't reach the bottom. With no oxygen, phosphorus is released from the sediment and feeds algal blooms. Then oxygen delivered at depth: a Speece Cone® on the shore returns oxygen-rich water sideways along the lakebed and, unlike aeration, doesn't mix the lake. The result is an aerobic cap over the sediment. A chart shows the oxygen capacity in pounds a day of six lakes and reservoirs listed on eco2tech.com, from San Pablo Reservoir and Lake Hodges at 10,000 to Marston Reservoir at 2,200. It ends on the ECO₂ logo.

Speece Cone® systems at work, made for ECO₂ Technologies. An animated map with no sound.

An animated map of the United States with no sound. It opens on the words ECO₂ installations: Speece Cone® systems at work. The US projects listed on eco2tech.com drop onto the map, sized by oxygen capacity and colored by use: sewer odor and corrosion, then lakes, rivers and harbors, then treatment plants and industry. A footnote says one project, MBR package plants, is in several locations and is not mapped. A counter climbs to 153,445 lbs of oxygen a day, the combined capacity of all 56 projects. Callouts pick out the Savannah Harbor Expansion at 40,000 lbs a day, the TRA Central Plant Influent Pump Station in Dallas at 14,000 and San Pablo Reservoir at 10,000. A box adds the projects in Asia: Hong Kong at 5,200 lbs a day and Shanghai at 2,205. It ends on 34 million lbs of oxygen dissolved every year by ECO₂ systems and the ECO₂ logo. The projects and capacities are ECO₂'s own, from eco2tech.com in October 2026.
