Summary:The present invention relates to a system and process for treating a feedwater wherein the system includes at least one RO or nanofiltration unit that receives a feed under high pressure and produces a concentrate that is directed to and held at low pressure in a concentrate accumulator. Generally the permeate or the inlet feedwater is maintained at a constant flow rate. Periodically the system is switched from a mode 1 or normal operating process to a mode 2 where the concentrate is drained from the concentrate accumulator. However, in mode 2, the feedwater is still directed into the system and through the RO or nanofiltration unit which produces the permeate and the concentrate. La presente invención se refiere a un sistema y proceso para tratar un agua de alimentación en donde el sistema incluye al menos una unidad de RO o nanofiltración que recibe una alimentación a alta presión y produce un concentrado que se dirige y mantiene a baja presión en un acumulador de concentrado. En general, el agua de alimentación permeada o de entrada se mantiene a un caudal constante. Periódicamente, el sistema cambia de modo 1 o proceso de operación normal a modo 2 donde el concentrado se drena del acumulador de concentrado. Sin embargo, en el modo 2, el agua de alimentación aún se dirige al sistema y a través de la unidad de RO o nanofiltración que produce el permeado y el concentrado.
