Delta Complete Package Plant
Delta Package Sewage Treatment Plants are custom designed to the particular sewage treatment needs of each location. These sewage treatment solutions are suitable for permanent or temporary use in areas outside municipal wastewater systems, each Delta Package Sewage Water Treatment Plant is custom-built at the factory and shipped to the project site as a self-contained unit that requires minimal assembly. They are the perfect solution for small sewage systems.

Secondary and tertiary treatment systems include aeration, settling, filters, clear well chambers, disinfection methods and other ancillary equipment such as blowers, pumps, electrical controls, aeration equipment, filter media and liquid level sensors. Other items, such as gratings, handrails, stairways and flow measuring equipment can be provided. A Delta Treatment Systems representative can assist you in specifying the system that will meet your requirements.


How Delta Advanced Package Sewage Treatment Plants Work:

When waste enters a stream, it becomes food for bacteria present in the water. As long as there is sufficient oxygen in the stream, the bacteria consumes all organic material over time. Delta Package Treatment Plants use the same process to break down domestic wastewater, only it does it faster and more efficiently using sewage treatment plant technologies.

Delta's self-contained modular wastewater treatment plants take in wastewater and process it through an extended aeration and oxidation process that purifies the sewage by the destruction of organic compounds using naturally occurring bacteria. Continuous mixing with air encourages the biological organisms to consume and break down the organic materials. The result is a clear and odor-free effluent.

A typical Delta Package Treatment Plant includes the following elements:

Delta Package Treatment Plants offer options beyond individual sewage and septic systems or costly sewer connection to builders and site developers.  

Because Delta Package Treatment Plants can be pad-mounted, terrain or soil conditions are not a factor when selecting an installation site. Delta Package Treatment Plants are self-contained units that effectively process the wastewater turning out high-grade, clear effluent. Delta’s Package Treatment Plants can also be installed at grade depending on site conditions.
