The accept tank has at least two mixers (10), and at least one of the mixers (10) are located within the arched end (2). The mixers (10) have propellers (12) at ends of their axles (11). For best performance at least two of the axles (11) of the mixers (10) are horizontally aligned to the direction of the elongated section (1) and the center line of at least one axle (11) of the mixer (10) is aimed at a point, which is at the sidewall (3) of the elongated section (1) at least 25% of the length of the elongated section (1) away from the beginning of the elongated section (1). Preferably the propellers (12) are positioned and/or aligned symmetric with respect to the centerpoint of the accept tank. Within the center of the elongated section is an elongated centerpiece (6) having rounded ends.
