Separate the return stages
The first displaced product, heavily contaminated liquid, reusable solution and final discharge may need different destinations. Draw those routes and define the decision logic. A recovery tank is useful only if the returned material is suitable for its next duty.
Consider carryover
Product families, allergens and flavors may make cross-use unacceptable even when a process reading appears normal. Decide whether dedicated circuits, separate tanks or single-use operation are appropriate with the responsible food-safety and production teams.
Quantify with a measured baseline
Any water, energy or chemical comparison should state the boundary, products, sequence and number of cycles measured. No fixed savings percentage follows just from installing a recovery tank. Include discharge requirements and utility use in the review.
