It is used to enhance your on- site wastewater dispersal system. You can be proud that by purchasing your ECOPOD-N system, with a minimum amount of maintenance, you can directly contribute to a cleaner, safer environment. All wastewater treatment systems of this type work by using bacteria that nature provides. By pumping air into the system, aerobic bacteria grow and thrive in large numbers. This population of bacteria speeds up the process of breaking down domestic wastewater, making it safer to release into the environment. This entire process takes place within the walls of your specially designed ECOPOD-N Treatment System. The result of this process is a clear, odorless discharge. By following a few simple steps that you will find in this manual, your ECOPOD-N Fixed Film Wastewater Treatment System will provide you with years of service and the knowledge that you are doing your part to protect public health and our groundwater, lakes, rivers, and streams. The ECOPOD-N Fixed Film Wastewater Treatment System may be only one of several components required by your health department to provide a complete on-site system. PROCESS DESCRIPTION The ECOPOD-N Fixed Film Wastewater Treatment System is a device that houses an engineered plastic media specifically designed to treat domestic wastewater. There are no moving mechanical parts or filters in the chamber or tank that houses the ECOPOD-N. Wastewater first enters a pretreatment/settling tank similar to a conventional septic tank. In this tank, debris and settleable solids settle to the bottom and are decomposed by anaerobic bacteria. The clarified wastewater then enters the ECOPOD-N, which is submerged in a separate chamber or tank, where it is introduced into an oxygen rich environment. An external air compressor is connected to the ECOPOD-N and provides the necessary air to the system. In this oxygen rich environment, a colony of bacteria, called the biomass, develops and is capable of digesting (breaking down) biodegradable waste. This is a continuous process as the biomass is supplied with incoming wastewater and oxygen. In this system, conditions are favorable only to attached growth bacteria. This means that the most common disadvantages of other types of systems are eliminated. No rising sludge, floating sludge or washouts can occur. In addition to cBOD and TSS reduction, ammonia nitrogen is one of the contaminants found in wastewater. Nitrification of the ammonia and denitrification of nitrates occur within the ECOPOD-N system. A 50%+ removal rate of total nitrogen is common without any type of recirculation or cycling of the blower. HOMEOWNER CARE AND OPERATION INSTRUCTIONS The ECOPOD-N Fixed Film Wastewater Treatment System has been designed and built to provide long term, reliable and efficient service. Once the unit has been installed (see installation instructions), the unit will operate with a minimum amount of attention. Please reference the system’s Data Plates that are located on the air pump and the alarm panel in the event that a problem arises or service is required. The following should be performed as checks for system functioning: Daily • Observe the warning device, which comes on when the power to the air pump has been interrupted, when the air supply system has malfunctioned, or there is a high water level in the treatment plant. If the alarm is activated, check for a blown fuse or thrown circuit breaker. Check the air pump to be sure it is operating. Once accustomed to the soft humming sound of a properly operating unit, any unusual noise is an indication of malfunction. If an unusual noise is detected or total failure is observed, call an authorized Delta service provider or dealer/ distributor. Weekly • Check the treatment plant for offensive odor. If such a condition should develop, call an authorized Delta service provider or dealer/distributor. Every 6 Months (performed by a certified service provider) • Inspect and make any necessary adjustments to mechanical and electrical components. • Inspect the air filter on the air pump. Rinse with warm water if necessary. (See installation instructions.) Do not use oil or other solvents. • Inspect effluent quality’s color, turbidity and check for any odor. • Take a sample from the reactor tank to check the sludge level described in the “Solids Removal” section. • The homeowner must be notified in writing if any improper operation is observed and cannot be corrected at the time of service. Ongoing Maintenance and Care The following should not be used or disposed of into the system: • Greases, fats, oils, pesticides, herbicides, or any other toxins. • Garbage disposal should be used sparingly. Dispose of food waste, grease, etc., in the trash. Food waste represents additional loading on the Fixed Film Wastewater Treatment System and could increase pump-out frequency.
