Aqua Safe® Operation

Aqua Safe® Aerobic Treatment Unit

Description & Plant Operation

The Aqua Safe® series of advanced aerobic treatment units are designed to treat domestic wastewater from residential homes, multiple homes, or light commercial applications. The wastewater is treated by the patented Aqua Safe® process and the highly treated effluent is disposed of per state regulations by multiple disposal applications.

The Aqua Safe® individual home sewage treatment system is an inexpensive self-contained wastewater treatment system that features an extended aeration activated sludge process which reduces sewage to an odorless safe discharge in 24 hours. Aqua Safe® was tested according to requirements listed in NSF/ANSI Standard 40 and 245 and is listed by NSF as meeting or exceeding Class 1 Effluent requirements.

Aqua Safe® series of treatment units are constructed out of fiberglass and concrete. Aqua Safe® A.T.U.’s are available in 500gpd – 1500gpd with optional add-on configurations to assist with ease of installations.

Pre-treatment tank
This is an optional item on the Aqua Safe® unit unless state code dictates otherwise. The pre-treatment tank is equipped with a discharge baffle extending vertically down into the liquid set to draw between the floatable and settleable solids. This is set to prevent larger solids from passing through to the mixing zone due to peak hydraulic loading periods. There are Aqua Safe models with pre-treatment tanks laminated to the A.T.U. for ease of installation, and access ports are appropriately located above baffles for servicing.
Aeration or mixing zone
The Aqua Safe® series utilizes an extended aeration activated sludge process which effectively treats the effluent by distributing free dissolved oxygen into the mixed liquor in the aeration zone. This is accomplished by a compressor blowing air above the intake of the clarifier. As the air bubbles rise up through the process fluid, it creates a rolling action which enhances the mixing of the oxygen with the wastewater. This process allows aerobic bacteria and other microorganisms to convert the organic material in the wastewater into new cell mass. As the number of organisms increase, they clump together forming a floc, or biomass, which in turn, entraps additional organic matter for further treatment. As the effluent exits the system through the clarifier, the organic solids (floc) settle down through the quiescent zone of the clarifier back into the aeration chamber. The aeration chamber has a generous retention time of 40.7 hours which is about 70% larger than the normal design capacity of 24 hours for extended aeration. This additional retention time enable the unit to withstand greater hydraulic surge loadings without allowing solids to be washed out of the system.

During period of low flows through the treatment plant, organisms in the system consume other microorganisms as an energy source, thereby reducing the total volume of suspended solids. Periodically, however, it is necessary to pump out the excess solids (waste) that accumulate within the system.

Although the extended aeration process is considered to be a suspended growth process, the interior surface area of the aeration chamber, as well as the outer surface area of the clarifier, acts as a biological reactor or supporting media to which bacteria clings. For example, the AS500gpd unit has 17,940 square inches of clinging space on the interior surface area of the aeration chamber and 7,800 square inches of clinging space on the outside of the clarifier for a total of 25,750 square inches for bacterial organisms to cling and multiply.

Clarifier
Through hydraulic displacement, mixed liquid will enter from the bottom of the conical clarifier. The settleable solids will settle down the slope of the clarifier and re-enter the mixing zone for further aerated treatment. The polished effluent will rise upward through the clarifier to the discharge pipe. The average retention time in the clarifier is 7.3 hours. The conical design of the clarifier provides for a surface settling rate of .84 gpd/sq. ft., which is >10 times greater than required by 10 States Standards.
Pump tanks
When the method of effluent dispersal requires a pump application, the Aqua Safe® series has many models of pump tanks available with most being laminated onto the A.T.U. for ease of installation.
Disinfection
Tablet-fed chlorinators are usually located in the pump tanks in line with the discharge pipe for complete disinfection. The chlorinator is brought to grade for ease of servicing or adding chlorine. Liquid chlorinators are also available showing long term savings in chlorine cost. UV disinfection is another alternative than can be used.

The Aqua Safe® series of wastewater treatment plants come in fiberglass or concrete and in multitudes of configurations and volumetric sizes. Plants can be used individually or in conjunction with others for larger flows.

Aqua Aire® Operation

AQUA AIRE® Aerobic Treatment Unit

Description & Plant Operation

The Aqua Aire® series of wastewater treatment plants are in many ways similar to large township or municipality sewage treatment plants. They employ an extended aeration activated sludge process. This type of treatment depends primarily upon the use of air that is introduced by air passing from the aerator compressor to two diffuser/deflectors located in the forward section of the aeration mixing compartment. As wastewater enters the aeration mixing compartment simple hydraulic displacement is accomplished by the introduction of air which promotes the growth of aerobic organisms in much larger quantities than would occur naturally. These bacteria break down the organic solids in the wastewater. From the aeration mixing compartment, mixed liquid enters the settling or clarifier compartment from below a partition wall separation. No mixing occurs in this quiet zone where solids separate from the liquid and settle to the bottom of the clarifier and re-enter the mixing compartment. The liquid that separates from the solids in the clarifier continue to flow upward to the discharge pipe.

The Aqua Aire® models AA500T, AA500, AA600, AA750T, AA750, AA1000 and AA1500 are rectangular configurations comprised of an aeration mixing compartment and a clarifier compartment. These compartments are partitioned by an internal dividing wall in the treatment plant.

The Aqua Aire® models AA500-32 and AA500-35 are three compartment rectangular configurations partitioned by internal dividing walls in the treatment plant. They are comprised of a forward pre-treatment tank, a center aeration mixing zone and a settling or clarifier compartment. Wastewater first enters the pre-treatment tank compartment of the plant, then gravity flows through a 4″ SDR 35 PVC inlet to the center aeration mixing zone. The mixed liquid then enters the settling or clarifier compartment and continues to flow upward to the plant’s discharge pipe.

Wastewater first enters the pre-treatment tank compartment of the plant, then gravity flows through a 4″ SDR 35 PVC inlet to the aeration mixing zone. The mixed liquid then enters the settling or clarifier compartment and continues to flow upward to the discharge pipe. From the plant’s discharge pipe, the final effluent then passes through a disinfection or chlorination device into the pump tank compartment for storage and contact mixing. The treated and disinfected effluent is then safely discharged, via an application pump, to a surface spray, subsurface drip, low pressure dose or absorptive mound disposal area. The results of the Aqua Aire® process is a clear, odorless effluent discharge, which meets and exceeds state and national water quality standards.
