Residential & Commercial Sewage Treatment System Why are residential and commercial consumers buying Navadic Wastewater Treatment Systems? It's Simple The unique design of the NAYADIC system provides 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 outside with a protective housing.

It's Easy
The NAYADIC Wastewater Treatment System utilizes a design that is engineered to 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.

Features
Five(5) Plant Sizes Available - To insure proper sizing of each plant, NAYADIC provides five individual treatment plant capacities: 500, 600, 800, 1000, 1500 gpd (gallons per day).

Low Installation Cost - The lightweight, fiberglass construction eliminates the need for expensive equipment to transport and install the NAYADIC. Also, the single-tank design eliminates the need for pre-treatment tanks or secondary filter tanks.

Minimal Space Requirements - The NAYADIC can be installed in a very small area (approx. 7' diameter). In addition, the sloped "hopper-bottom" design of the outer basin requires an even smaller area at the bottom of the excavation. This is especially advantageous when digging in rocky soils or in areas with a high water table.

Two (2) Year Warranty - NAYADIC, Inc. warrents each treatment plant to be free of defects in workmanship for a period of two years from the date of installation.

Quiet, Odorfree Operation - The NAYADIC utilizes a totally "aerobic" process which eliminates the offensive "rotten egg" odors frequently observed with septic tanks.

Easy Access for Service - All necessary inspections and maintenance can be performed by simply removing the access cover of the NAYADIC plant. The NAYADIC does not have any moving parts or electrical componants located within the tank. The compressor is located externally to allow for quick and easy access.

Low Maintenance Cost - Other than routine inspection and periodic pumping of excess, solids, the NAYADIC requires very little maintenance. In many instances, repair of the compressor can be performed in the field, by an authorized NAYADIC service representive.
