Industrial wastewater streams where volume reduction and water recovery matter.
The X-Series was developed to crystallize some of the most difficult industrial wastewater streams encountered in the field. Its architecture was intentionally designed to be broadly tolerant of wastewater chemistry, with application-specific adjustment focused primarily on scaling control, upstream solids management, chemical dosing, and materials selection.
Built to handle difficult chemistry without narrowing the application landscape.
Slipstream developed the X-Series around the premise that industrial wastewater crystallization should not be restricted to only clean, predictable, or narrowly defined feed streams. The platform was engineered to handle severe wastewater chemistry, while application-specific engineering focused on protecting heat-transfer efficiency and keeping the system maintainable.
The principal application levers were anti-scaling chemical injection, upstream solids removal where needed, appropriate materials selection, and access to the heat-transfer surfaces for cleaning and scale removal.
Applications documented in Slipstream’s technical and commercial materials.
The following sectors reflect the breadth of markets Slipstream identified, evaluated, or served. The successful crystallization of landfill leachate illustrated the platform’s ability to address wastewater well beyond conventional clean industrial concentrates.
Metal Finishing and Plating
Metal-finishing facilities often generate concentrated rinses and drag-out streams containing dissolved metals, treatment chemicals, and variable pH.
- Plating drag-out and rinse water
- Cadmium, zinc, nickel, tin, copper, and silver-bearing streams
- Anodizing rinses
- Selected pretreated metal-bearing wastewater
Centralized Waste Treatment
CWT facilities manage diverse industrial wastewaters and can benefit from reducing liquid-disposal volume or recovering water within a broader treatment train.
- Metal-bearing wastewater
- Oil-bearing wastewater
- Selected high-organic streams
- Concentrated residuals following upstream treatment
Landfill Leachate
Landfill leachate represented one of the clearest demonstrations of the X-Series architecture’s tolerance for difficult and variable wastewater chemistry. Slipstream targeted both raw and pretreated leachate for crystallization.
- Raw landfill leachate
- Post-precipitation leachate
- Residual streams after upstream treatment
- Liquid-volume reduction before off-site disposal
Oil and Gas Produced Water
Historical market materials included produced water and flowback streams, subject to detailed review of salts, hydrocarbons, suspended solids, and corrosion requirements.
- Shallow-well produced water
- Shale-gas produced water
- Hydraulic-fracturing flowback
- Selected pretreated oilfield residuals
RO Reject and DI Regeneration
Membrane and ion-exchange systems create concentrated backend streams that may be suitable for further thermal volume reduction or crystallization.
- Reverse-osmosis concentrate
- Deionization regeneration waste
- High-TDS polishing residuals
- Concentrate from upstream water-recovery systems
Remediation and Mine Water
Project-based treatment can create a need for compact water recovery and residual-volume reduction when long-term infrastructure is impractical.
- Environmental remediation wastewater
- Mine drainage and leaching residuals
- Acidic mine drainage
- Temporary or distributed treatment projects
Agricultural and Food-Related Streams
Slipstream’s historical materials identified selected agricultural wastewater streams, though organic loading and fouling behavior require careful review.
- Produce rinsing and packaging wastewater
- Dairy-related wastewater
- Concentrated wash-water residuals
- Streams following upstream solids separation
Chemical and Heavy Industrial
The platform was also positioned for specialty manufacturing and chemical processes where wastewater disposal, water availability, or discharge restrictions create a strong treatment need.
- Chemical manufacturing residuals
- Specialty industrial process wastewater
- High-TDS batch streams
- Application-specific OEM integration
Broad wastewater applicability combined with efficient crystallization.
The X-Series was intended for applications where the economics and operational value of crystallization justified controlling scale, removing problematic solids upstream, or tailoring materials and dosing to the wastewater stream.
Extreme energy efficiency at the point of crystallization.
The central value of the X-Series architecture was its ability to reuse thermal energy while carrying the process beyond evaporation and into crystallization. Mechanical vapor recompression in Stage I and vapor return from Stage II were intended to reduce the energy penalty normally associated with driving wastewater to solids.
Scaling was a heat-transfer management problem—not a reason to exclude difficult wastewater from consideration.
When scaling occurred, the system was designed so the heat-transfer surfaces remained accessible for cleaning and scale removal. Maintainability was therefore part of the process architecture, not an afterthought.
Configure the protection strategy around the wastewater stream.
The key engineering question was not whether the X-Series could address a narrow category of wastewater. It was how best to preserve heat-transfer performance and reliable operation while crystallizing that stream.
- Scaling tendency and the appropriate anti-scaling chemical program
- Suspended-solids loading and whether upstream solids removal is beneficial
- Representative wastewater chemistry and corrosion requirements
- Heat-transfer cleaning frequency and maintenance access strategy
- Average, minimum, and peak wastewater flow
- Available natural gas, propane, electricity, or steam
- Recovered-water reuse objective
- Desired solids consistency, handling, and disposal method
Primary Application Levers
Documented X-Series sizes for distributed industrial treatment.
The X-Series product range was designed around compact industrial capacities rather than utility-scale flow.
1 GPM nominal capacity, equivalent to approximately 60 gallons per hour.
3 GPM nominal capacity, equivalent to approximately 180 gallons per hour. This was Slipstream’s primary commercial product.
5 GPM nominal capacity, equivalent to approximately 300 gallons per hour.
The X-Series was developed to address a broad application landscape. Feed testing and engineering review remain important for selecting anti-scaling chemistry, upstream solids removal, wetted materials, operating setpoints, and maintenance intervals—not for artificially restricting the platform to only mild or predictable wastewater.
