# §162.050-17. Separator test rig.

- (a) **This section contains requirements for test rigs used in approval testing of separators.** A diagram of a typical test rig is shown in Figure 162.050-17(a).
- (b) **Each mixture pump on a test rig must—**
  - (1) Be a centrifugal pump capable of operating at 1,000 revolutions per minute or more;
  - (2) Have a delivery capacity of at least 1.5 times the maximum throughput at which the separator being tested is designed to operate;
  - (3) Have a maximum delivery pressure that is equal to or greater than the maximum influent pressure at which the separator is designed to operate; and
  - (4) **Have either bypass piping to its suction side or a throttle valve or orifice on its discharge side.**
- (c) The inlet piping of the test rig must be sized so that—
  - (1) Influent water flows at a Reynolds Number of at least 10,000;
  - (2) The influent flow rate is between one and three meters per second; and
  - (3) **Its length is at least 20 times its inside diameter.**
- (d) Each sample point on a test rig must meet the design requirements described in Figure 162.050-17(d) and must be in a vertical portion of the test rig piping.
