Biological Chip Reactor (BCR)

Normal reactors carry a biological loading of 2,000-3,000 mg/l. By adding this media we increase the biological loading to 8,000-12,000 mg/l.

Passing through an Anoxic reactor the effluent flows by gravity into the BCR. Within the reactor, the effluent is treated by an aerated process. Normal oxygen levels in the reactor range from 2-4 mg/l. The reactor is filled (40%) with a plastic media.

This media promotes biological growth, allowing the reactor to carry an extremely high biological loading. Normal reactors carry a biological loading of 2,000-3,000 mg/l. By adding this media we increase the biological loading to 8,000-12,000 mg/l. This allows us to reduce the reactor space required by a normal biological process by a factor of as much as four. See example of Bio-Carrier Media above.

WSI plants are designed to produce R1 Water under Title 22 water for the State of Hawaii and the State of California. This means that every piece of equipment we choose for your plant is already approved by these states under these water reuse guidelines.

Packaged Systems

Pre-packaged systems incorporate BCR technology in a modular design that are easily expandable with capacities from 10,000-200,000 GPD.

WSI will design and install packaged systems to meet any wastewater treatment requirement. Packaged systems may include a SBR system, a BCR system, a sludge dewatering system, a post-treatment system, an odor control system, or any combination of the above systems.

Packaged systems have been created in a modular design to provide ease of expandibility, decrease installed costs and installation time. Systems can be configured for BOD removal, nitrification, enhanced nutrient removal, and strict disnfection requirements for reuse water.

Sequencing Batch Reactors (SBR)

SBRs are fill and draw activated sludge treatment systems for capacities from 10,000-20,000 GPD.

Sequencing Batch Reactor Systems utilize two of more fill-and-draw reactors which are completely mixed. Almost all SBR systems operate in a five-step mode: filling of the reactor basin, a reaction phase, a settling phase, a decant phase, and an idle phase. The reaction phase is usually a combination of aerobic and anoxic phases to achieve high levels of BOD and nitrogen removal. In certain circumstances, the reaction sequence can be modified for phosphorous removal.

WSI designs SBR systems that are mechanically robust and completely automated. If required, systems can be configured with sludge dewatering of digestion basins. In special applications, WSI can provide equalization basins to ensure proper sequencing of the SBR system.
