Batch technology, as its
name implies, treats wastewater in "Batches". This type of technology can be contrasted with other technologies that treat septic tank effluent in a
continuous stream. The aerobic Batch-Treat process functions in an enclosed
and liquid environment in a single tank module. Treatment is accomplished by
turbulent aeration of incoming waste in an initial chamber and batch treatment
of sewage in separate aeration and settling chambers. NPS proprietary
Batch-Treat systems provide efficient wastewater treatment for applications such
as Residential (Single Family Homes and Apartments), Gas Stations, Industrial
Plants, Mobile Home Parks, Recreational Areas, Restaurants, Schools and Resorts.

NPS Batch-Treat Features
- Noise and Odor Free
- Highly efficient oxygen transfer and
mixing ensures that the plant and effluent are essentially
odor-free. The only mechanical operation is submersible pumps and,
under water, these pumps are virtually inaudible.
- Higher Operating Temperatures.
- NPS systems retain heat from incoming
sewage, bacteria activity, and heat generated by the submersible
pumps. Higher temperature increases enzyme and biological activity
that increases the efficiency of the Batch-Treat process. The
plant effluent has a high dissolved oxygen content, and does not
freeze, except in extreme conditions.
- Peak Load Reserve
- The Reserve Volume zone in NPS systems
acts as a buffer to absorb large sewage liquid inflows with
minimal effect on the process. This volume retention and the
Batch-Treat process cycle creates a longer liquid retention period
than other systems.
- Low Sludge Build-Up
- The NPS systems continuously
return sludge to the Aeration zone for further aeration and biological
breakdown. This results in extremely low sludge deposits that are
mostly biological ash and insoluble particles requiring less
- Completely Automatic, Minimal
- All NPS Batch-Treat
systems are completely automatic and require no regular supervision
while operating. The only maintenance required is a periodic check
