    Packaged Wastewater Treatment Plant Meets Tricky Challenge

    Packaged Wastewater Treatment Plants offer many advantages, flexibility notwithstanding. One plant in particular, located in Georgia, needed to be upgraded to handle the increased flows from a growing city and to address new effluent discharge regulations.  The tight plant site offered minimal opportunity for routine expansion of the packaged wastewater plant volumes, hence special designs were needed. Learn how this 200,000 GPD system is thriving.

Sanitaire pioneered the concept of wide band aeration with the introduction of the SANITAIRE® Stainless Steel Non-Clog diffuser in 1967. Since its introduction, the SANITAIRE wide band diffuser has become the standard in the industry with over 500,000 units in service.

Traffic Rated Screen Drain Grates Traffic Rated Screen Drain Grates

Most lift stations and basins require separate drain inlets that do little to keep out large solids such as gravel, branches and general litter than can destroy pumps. ClearBlu has developed a traffic rated grate system that utilizes perforated plate with 1/4″ holes. The grate sits in a heavy grate frame that embeds in concrete. By embedding the frame in concrete, traffic weight is carried by the frame and concrete and not the basin. This allows the basin to be secured and sealed to a poly or fiberglass basin.

Energy Efficiency Boosted By Replacing Controls Not Blowers Energy Efficiency Boosted By Replacing Controls Not Blowers

At the wastewater treatment facility, the biggest energy consumer is almost always the multistage aeration blowers. Replacing these blowers with high speed turbo blowers can save energy but the short-term cost to replace the existing blowers, reroute pipe and set new foundations can make the change a hard sell.

ABOUT AERATION

 

A common first step in the secondary treatment process is to send wastewater to an aeration tank. In an aeration tank, bacterium is used to effectively break down pollutants into less harmful components. Wastewater aeration provides the appropriate oxygen level so that aerobic bacteria can thrive in degrading pollutants such as iron and manganese as part of the wastewater treatment process. Aeration can also be used to destroy anaerobic bacteria that perish in the presence of oxygen. Aerobes that can break down pollutants 10-100 times faster than anaerobes are used most frequently.

Aeration is also used to improve waste lagoons and other waterways such as lakes and reservoirs where oxygen deficiency contributes to taste, odor and pollutant problems. Equipment used for wastewater aeration includes low cascades, jet fountains, spray nozzles, blowers, submerged perforated pipe and porous plates or tubes. Whether the water is thrown into the air via a fountain or diffused by air bubbles being blown or drawn into the wastewater in an aeration tank, aeration works by increasing the area of contact between the oxygen in the air and water.

The most common wastewater aeration process in use today is the air diffusion process, where air is introduced from blowers through diffusion tubes suspended in a spiral flow tank, or in some cases, through diffuser plates in the bottom of the aeration tanks.
