Industrial Wastewater Crystallization

Recover the water. Crystallize the waste.

Slipstream ZLD is a modular thermal crystallization platform that combines falling film evaporation, mechanical vapor recompression, and controlled solids dewatering. The flagship X-180 is an engineered system for processing concentrated industrial wastewater at a nominal rate of 3 gallons per minute.

The X-180

The primary commercial X-Series configuration.

The X-180 is a compact, fully engineered wastewater crystallizer for industrial generators whose treatment volumes do not justify a conventional large-scale ZLD plant. Its architecture integrates evaporation, vapor recompression, distillate recovery, secondary crystallization, and controlled solids discharge.

Process Architecture

One integrated path from wastewater to distilled water and solids.

Rather than relying on a stand-alone evaporator followed by separate sludge-drying equipment, the X-Series combines primary water recovery with a dedicated Stage II crystallization chamber.

Explore the full process
01

Feed and Recirculate

Wastewater is introduced through the integrated feed system and circulated through the Stage I reactor.

02

Evaporate and Recompress

Falling film evaporation produces low-pressure vapor, which is mechanically recompressed to raise its usable temperature and pressure.

03

Recover Distillate

The compressed vapor is reused as thermal energy and condensed into recovered distilled water for reuse, storage, or further treatment.

04

Crystallize and Discharge

Concentrate moves to Stage II, where low-pressure steam and an internal rake support further dewatering and controlled solids removal.

Stage II vapor is returned to Stage I, creating an additional evaporative effect and extending the system’s internal energy-reuse cycle.
Core Technology

Established thermal principles combined in a distinctive architecture.

Slipstream’s advantage is not based on an unfamiliar physical process. It comes from integrating proven evaporation and vapor-recompression principles with a closed-vessel crystallization stage configured for compact industrial deployment.

F

Falling Film Evaporation

A recirculated liquid film moves across the Stage I heat-transfer surface to support efficient evaporation.

M

Mechanical Vapor Recompression

Low-pressure process vapor is compressed and returned as a reusable source of heat-transfer energy.

II

Closed-Vessel Crystallization

A separate second stage concentrates the remaining slurry and manages solids with monitored weight and an internal rake.

The Core Advantage

Energy-efficient crystallization without sacrificing maintainability.

The heart of the X-Series value proposition is the efficient reuse of thermal energy while carrying wastewater beyond concentration and into crystallization. Mechanical vapor recompression recycles Stage I vapor, while Stage II vapor returns to Stage I to create an additional evaporative effect.

Scaling is addressed as a manageable heat-transfer challenge. Anti-scaling chemical injection and upstream solids removal can be configured around the feed, while accessible heat-transfer surfaces support inspection, cleaning, descaling, and replacement when fouling affects performance.

Strategic Opportunity

An existing industrial platform ready for its next strategic owner.

Slipstream ZLD is positioned for discussions with organizations capable of advancing the X-Series through engineering refinement, manufacturing, integration, market access, licensing, or acquisition. The platform may be especially relevant to established industrial-water companies seeking a compact thermal crystallization capability.

Technology Licensing Market-, application-, or territory-based licensing structures.
OEM and System Integration Incorporation of the architecture into an established treatment portfolio.
Joint Development Modernization, validation, and application-specific engineering with an aligned partner.
Technology Acquisition Evaluation of the intellectual property, technical assets, designs, and accumulated know-how.
Engineered Beyond the Concept Stage

An engineered platform informed by fabrication, operation, and field experience.

The X-Series is a developed industrial equipment platform shaped by a multi-year effort to make crystallization smaller, simpler, and more maintainable. Its present architecture is supported by complete systems that Slipstream built, operated, and deployed beyond laboratory validation.

That development history is central to the opportunity today. The platform incorporates practical decisions about materials, automation, vapor management, access, serviceability, solids handling, and integration within an operating industrial facility.

Published capacities and equipment dimensions reflect historical X-Series documentation. Distillate quality, recovery, energy use, operating cost, chemical dosing, maintenance intervals, and final materials selection depend on operating conditions and should be confirmed through current engineering review.

Evaluate the X-Series for an application, partnership, or acquisition.
