The successful application of natural biological processes for purification of sewage can be traced back to 100 years ago. Today more than 90% of large municipalities apply enhanced biological processes for treatment of large quantities of wastewater. In other words, the biological technology has been well accepted and approved as a reliable and economical means for municipal sewage disposal.

AQUASOL engineers further explored new environmental biotechnology, and developed an advanced MicroEntrapd biotechnology system for sewage treatment. The advanced MicroEntrapd biotechnology not only accelerated the natural biological purification processes but also greatly reduced sludge production. New AQUASOL MicroEntrapd bioreactor systems that integrated the MicroEntrapd biotechnology with innovative engineering design proved to be more reliable, efficient and compact in design. In addition, it uses no clarifier and no chemicals that are commonly used in existing biological treatment systems.
