Figure 3-3. Part II of DA Form 1713-R (Daily Production Log - ROWPU)
The reading from the product water flow gauge on the ROWPU should be measured
continuously during operation.
The reading from the RO pressure gauge should be recorded every hour during normal operation.
The pressure differential reading from the media filter shows the difference in pressure from the
top to the bottom of the filter and indicates the media status.
The reading from the raw water flow gauge should be carefully noted since the ROWPU can
sustain serious damage if sufficient water flow is not maintained.
The TDS reading can come from either the meters equipped on the ROWPU or from the portable
TDS meter assigned to operators. The reading is taken on the raw water side to determine production
rates and also on the product water side.
