2.1 System Configurations
The configuration of the TEQUATIC™ PLUS F-150 C-Series skid will depend on the purpose of the
system as well as the scale. The system can be a single skid, or multiple parallel skids for larger scale.
The optimal configuration will be site-specific, but should include some of the following aspects:
•
Parallel Systems:
When parallel systems are employed, it is recommended that valving be utilized
on all lines to permit isolation of any single system for maintenance. Check valves should also be
utilized to prevent one system backfeeding into another system.
•
Preconditioning:
Preconditioning may be required for process water that falls beyond the scope of
the system. This may include, but is not limited to, prescreening of large particulate material greater
than listed in the specifications section above.
•
Feedwater Supply:
The feedwater is best supplied from a holding tank. The feed tank will buffer
variations of influent flow with time, and if recommended, it also permits the concentrate to be
returned back to the tank for greater filtration efficiency. The feedwater supply to the skid needs to
be pressurized. This is typically accomplished with a pressure-controlled pump. The skid controller
has a pump control dry contact, as well as a feed-tank-low sensor input.
•
Filtrate Effluent:
The filtrate effluent is the primary treated discharge from the system, and should
not have appreciable back pressure. This line contains a system-controlled valve. This is typically
best served with a holding tank to accommodate variations in flow. A tank-full sensor dry contact
input is available for monitoring the status of the filtrate tank.
•
Concentrate Purge:
The concentrate purge is a system-controlled, pressurized discharge of the
primary filtration concentrate. The discharge point should be open-air or other sump means for
disposal or further processing.
•
Service Drain:
The service drain is manually controlled, and must be non-pressurized and located
entirely below the height of the system. The discharge should be open-air or fully vented, and
capable of receiving (expelling) air pressure during a system bleed operation.
•
Concentrate Return:
In some cases, a portion of the processed water can be returned back to the
feedwater tank, called the concentrate return. This is manually controlled, and should be a non-
pressurized line. To prevent this line from draining the system, it should be elevated above the
height of the tank and contain a siphon break located above the height of the system, such as an
open-air discharge back into the tank.
