S-400 UNIT


The S-400 system meets NSF/ANSI standard 40 class I.

The SludgeHammer S-400 is our system for single family residences up to 400 GPD. Use where advanced treatment is necessary.

The SludgeHammer is certified to have met the Class 1 treatment standards when tested by NSF International. The SludgeHammer S-400 model treats domestic wastewater loads up to 400 gallons per day and consists of the basic SludgeHammer® ABG column installed in the inlet chamber of a 1,500 gallon standard septic tank.

Air is delivered to the SludgeHammer column where it is distributed into the column through a micro fine-bubble diffuser. As the air rises it displaces liquid in the column setting up circulation through the column with liquid entering the column at the base and leaving at the top. A packet of proprietary “SludgeHammer Blend” bacteria and enzymes is introduced into the unit and held in a central refuge where it is supplied with a continuous stream of aerated liquid.
