THE HIGHEST QUALITY EFFLUENT
AT THE HEART OF AN ENVIROQUIP MBR System is a tailored biological
process that virtually eliminates pollutants such as biochemical
oxygen demand (BOD), nitrogen and phosphorus that can cause
fish kills and algae growth (eutrophication).
Microorganisms that are created during biological uptake of
dissolved pollutants are filtered through multiple protective
barriers to levels that are generally not detectable by standard
methods. In fact, fecal coliform concentrations are normally
non-detectable in MBR permeate before post-disinfection, as
compared to 100,000 cfu/100ml in traditional secondary effluent.

THE UNR™ PROCESS
Coupling
state-of-the-art technologies together, Enviroquip has developed
the Ultimate Nutrient Removal (UNR™)
process, guaranteed to meet the most stringent nutrient
limits. Different treatment levels are shown below along
with typical
effluent quality.
| a Limits
are a function of process design and are dependent on operating
conditions. |
| b Assuming Standard Methods of detection
and an average of at least 24-hr composite samples. |
| c Assumes combination of enhanced
biological phosphorus removal and chemical coagulation. |
Each Enviroquip MBR System can include multiple technologies
in proven designs that allow for flexible and adaptable operation.
The ability of an Enviroquip MBR to operate over a range of
conditions generally improves overall system performance as
compared to conventional treatment processes and MBRs that
utilize hollow fiber type membranes. Some of the advantages
of an Enviroquip MBR System over other technologies are listed
below.
