The Remediator from Aquaworx by Infiltrator is an easy-to-install septic system remediation technology that can rejuvenate failing septic drainfields with minimal landscape disruption, according to the maker. Inserted into the tank, the system includes a fine-bubble air diffuser to aid bacteria growth and reduce biological clogging in the drainfield. It requires nominal operation and maintenance cost. Under normal operation, a septic system builds up a biomat that over time can become restrictive, resulting in clogged soil pores and system malfunction. The unit introduces oxygen into a bacterial growth media column, allowing bacteria to thrive and consume organic matter. These bacteria combine with the oxygen-rich effluent in the tank and move to the drainfield, reducing the clogging layer and the associated odors and wet areas in the yard. 800/221-4436; www.infiltratorwater.com.
