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.

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.
