| 摘要 |
A septic system and method for the removal of nitrogen contaminants, such as nitrates and ammonia, from a wastewater effluent. The system comprises one or more zeolite tanks which contain a regenerable, granulated zeolite material to receive wastewater effluent from a septic tank and to capture the nitrogen contaminants to provide a treated, decontaminated effluent to flow out of the tank into a leach field. The system includes a secondary treatment.tank to reduce suspended solids and the biological oxygen demand (BOD) of the wastewater effluent prior to introduction into the zeolite tank. The system also includes an ion sensor to monitor the ammonium ion concentration in the system and to signal the need to regenerate the zeolite tank with saline water.
