Beverage production · Existing-system review
Can RO concentrate recovery help a beverage factory with limited source water?
Review source-water availability, production demand and the existing RO operating records before deciding whether a separate recovery system is appropriate.
A shortfall can come from insufficient daily source-water supply, peak use, treatment capacity or storage arrangements. Establish where the constraint occurs, then assess concentrate recovery with the water quality and intended return route.

Put supply and demand on the same operating schedule
Available source water
Record how much the well or other source supplies each hour, when it is available and how this changes. State the daily operating or pumping periods.
RO flow records
Record main-system feed, permeate and concentrate flows with their sampling or measurement points. Include the operating conditions and any recent changes.
Production demand
Provide daily water use, peak flow and peak duration. Identify whether shortages last throughout production or occur at a particular time.
Usable storage
Describe the actual usable capacity of the raw-water and product-water tanks and their operating levels. Storage can buffer a peak, but it cannot make up an ongoing daily water-volume deficit.
Water-quality information
Keep source-water, RO feedwater, concentrate and any existing recovered-water reports separate. Identify each sample’s location, date and units.
Existing operating problems
Include membrane blockage, abnormal readings, maintenance work and other known issues. These need review before adding recovery equipment to the existing arrangement.
How a Senegal beverage project returned recovered water
In Qingze’s published Senegal beverage project, first-pass RO produced 9 m³/h of permeate and supplied a second pass producing 6 m³/h. The passes operate in series; their outputs are not added together as 15 m³/h of final water.
After the customer reported insufficient well-water supply, a separate RO concentrate-recovery unit was added. Its recovered permeate returned to the raw-water tank for mixing and retreatment through the main system.
Recovery route in that project
- Main-system RO concentrate enters a separate recovery RO unit.
- Recovered permeate returns to the raw-water tank.
- It mixes with groundwater and passes through the main treatment system again.
- The recovery unit’s remaining concentrate requires its own site arrangement.
The recovered permeate was not sent directly to beverage production. This project record does not establish a fixed recovery percentage, measured saving or zero-liquid-discharge result.
Review the return route and operating conditions together
RO separates feedwater into permeate and concentrate. Retained constituents become more concentrated in the concentrate stream, so a recovery proposal needs a review of water quality, membrane protection and operating conditions.
- Identify the recovered-water destination. Show where it returns, what it mixes with and which treatment follows.
- Review mixed-water conditions. Assess the proposed return flow with the existing raw-water supply and main-system requirements.
- Account for remaining concentrate. Include its destination in the site and equipment review.
- Separate recovery from main-system capacity. A two-pass RO system and a separate concentrate-recovery unit serve different parts of the water route.
- Confirm the supply boundaries. Identify the recovery unit, tank interfaces, pumps, pipework, controls and support included in the proposed work.
Recovery-unit size, return flow and operating settings require a project-specific assessment. If analysis, flow records or the proposed destination are missing, identify those gaps before confirming a configuration.
