Residential & Commercial Sewage Treatment System (by NAYADIC)

It’s Simple

The unique design of the NAYADIC system enables it to provide an exceptionally high degree of treatment with only minimal maintenance requirements. The single tank concept requires no internal moving parts. The compressor, which supplies air to the plant, can be located either inside an adjacent building (i.e. basement, garage, etc.) or provided with a protective housing if it is to be installed outside.

It’s Easy

The NAYADIC Wastewater Treatment System utilizes a design that is engineered to greatly exceed most nationally accepted standards. For example, the clarifier design provides more than 25 times the minimum surface settling area as required by the Great Lakes / Upper Mississippi River Board of State Sanitary Engineers: Recommended Standards for Sewage Works (10 States Standards).

The NAYADIC system also incorporates a circular, perimeter clarifier that provides not only a large surface settling area, but also a 360 degree effluent weir. This critical aspect of the NAYADIC system further enhances the settling capabilities of the plant by reducing the hydraulic velocity through the clarifier, thereby dampening the effects of hydraulic surges. This feature which is unique to the NAYADIC system, helps insure continuous high performance with only minimal, easy to perform maintenance requirements.

It Works

Because of its highly efficient design, the NAYADIC system is capable of producing a high quality effluent without the need of additional filtration equipment. The NAYADIC has been tested and certified under ANSI/NSF Standard 40 as a Class I System demonstrating a treatment efficiency of more than 95% removal of sewage contaminants.

The Process

The NAYADIC system consists of two treatment chambers in a single tank. The center aeration chamber is a circular tank with a sloped, open bottom which empties into the bottom of the outer clarifier chamber. Located in the center of the aeration chamber is an eight inch diameter draft tube which extends to four inches from the bottom of the clarifier. Air is released at the bottom of the draft tube through a disc plate diffuser. As the diffused air rises in the draft tube, it causes an upward flow of process fluid. This draws the settled solids from the bottom of the clarifier up through the draft tube where they are discharged at the surface of the aeration chamber. The design of the draft tube insures continuous and complete mixing of oxygen with the sewage. This allows for the growth of various aerobic organisms that biologically degrade the wastewater contaminants.

Gravity causes the aerated solids to settle back to the bottom of the tank where they are again drawn back up through the draft tube. As raw sewage enters the aeration chamber, it displaces biological solids from the aeration compartment to the clarifier. Quiescent conditions in the clarifier allow the digested solids to settle to the bottom of the clarifier where they are returned back to the aeration compartment. The clarified (treated) effluent flows slowly up through the clarifier and over a weir which extends around the periphery of the tank. The effluent collects in an outer trough where it discharges through a four inch pipe. A scum baffle located inside the overflow weir prevents floating solids from passing over the weir.
