Introduction
Brine management and zero liquid discharge, from desalination outfalls through MVR evaporators and crystallisers to brine mining, is a 1-week course for desalination, industrial water and environmental engineers that ends with a Brine Management and ZLD Option Plan for a case organisation. Organisations face saline plume concerns, costly evaporation ponds and thermal trains chosen without a salt balance or lifecycle cost view. Nominees already handle reject streams, sampling or project studies, and the course is taught as a modelling build on brine, plume and cost data. CoreConcept Training Center delivers this brine management and zero liquid discharge course.
Course Objectives
- Characterise reject brine from membrane and thermal desalination and industrial sources by salinity, density, scaling ions and residual treatment chemicals
- Model near-field plume dilution for submerged outfalls and diffusers and compare predicted salinity excess with a mixing zone limit
- Size a brine concentrator, MVR evaporator and crystalliser train from mass and salt balances and specific energy figures
- Compare zero and minimal liquid discharge options on capital cost, energy, chemical use, solid residue and recovered water
- Screen recovery routes for sodium chloride, gypsum, magnesium, bromine and lithium from concentrated reject brine
- Assemble a Brine Management and ZLD Option Plan with a preferred disposal and recovery route for a case organisation
Target Audience
- Desalination process engineering staff responsible for recovery ratio, concentrate quality and brine disposal routes
- Industrial water and utilities staff responsible for cooling tower blowdown, demineraliser regenerant and other saline reject streams
- Environmental engineering staff responsible for marine discharge monitoring, plume surveys and discharge permit data
- Project and technical studies staff responsible for evaluating evaporators, crystallisers and resource recovery options
- Operations support staff responsible for running or commissioning thermal brine concentration and salt handling units

Why Attend This Course
- Hand a Brine Management and ZLD Option Plan for a case organisation to the plant manager and the environmental lead for decision
- Choose between sea outfall upgrade, minimal liquid discharge and full zero liquid discharge using salt balances and lifecycle cost rather than vendor claims
- Avoid plume exceedances, leaking evaporation ponds and crystallisers that foul or produce unsaleable mixed salt
- Share brine analysis sheets, dilution worksheets and evaporator sizing templates with operations and project colleagues
Conclusion
Once back at work, the participant presents the Brine Management and ZLD Option Plan to the plant manager, the environmental lead and the project sponsor. They use it to decide whether to upgrade the outfall diffuser, add a brine concentrator and crystalliser, or pilot salt and mineral recovery, and to fix target recovery, energy and residue figures. After the first pilot run or plume survey under the plan, the unit should compare measured dilution, energy use and salt purity with the plan estimates and revise the option ranking.
Frequently Asked Questions (FAQ)
What should participants prepare before a brine management and zero liquid discharge course?
Participants should already handle reject streams, water sampling or project studies and be comfortable with mass balances on a spreadsheet. Bringing anonymised brine analyses, outfall layouts or energy data from their own site helps the modelling build reflect real conditions.
How does a brine management and zero liquid discharge course differ from a desalination plant operation course?
It starts where the desalination plant ends: the concentrate. Plant operation courses cover intakes, membranes and distillers producing water, while this course covers what happens to the reject stream through outfalls, thermal concentration, crystallisation and mineral recovery.
Why do zero liquid discharge systems need a brine concentrator before the crystalliser?
A concentrator removes most of the water at lower energy per cubic metre, so the crystalliser only handles a small, near-saturated flow. Skipping it makes the crystalliser larger, more energy hungry and harder to control for fouling and purge.
What do participants take back from the brine management and zero liquid discharge course?
Participants take back a Brine Management and ZLD Option Plan for a case organisation, with a brine analysis sheet, an outfall dilution check, evaporator and crystalliser sizing worksheets and a lifecycle cost ranking of disposal and recovery options.
