Indonesia’s industrial sector is expanding through manufacturing growth, downstream processing, mining, food and beverage production, chemicals, pharmaceuticals, and other resource-intensive industries. As these industries grow, so does the volume and complexity of industrial wastewater generated during production.
This is creating a stronger need for advanced wastewater treatment technologies that can reduce liquid waste, recover valuable materials, and improve water reuse. Vacuum evaporation systems are becoming an important technology for industries looking to manage concentrated wastewater streams while improving operational and environmental performance.
In the first half of 2026, Indonesia recorded IDR 1,010.6 trillion in investment, up 7.2% year over year. Downstream industries accounted for IDR 300.1 trillion, or 29.7% of total investment, with mineral processing and other resource-based industries among the major drivers.
Several industrial and environmental factors are contributing to the growing demand for vacuum evaporation technology in Indonesia.
Indonesia’s manufacturing sector remains in an expansionary phase. Bank Indonesia reported a PMI-BI of 51.43% in Q2 2026, with machinery and equipment, food and beverages, basic metals, and non-metallic mineral products among the strongest-performing subsectors.
Manufacturing expansion generally means higher production volumes and, consequently, greater wastewater generation.
Industrial processes can produce wastewater containing:
Conventional biological or membrane-based treatment may not always be sufficient for difficult wastewater streams. Vacuum evaporation provides an additional treatment and concentration step for applications where conventional methods face limitations.
Indonesia is actively promoting industrial downstreaming, particularly for minerals and other natural resources. The government reported that downstream investment reached IDR 300.1 trillion during the first half of 2026, with significant investment in nickel, bauxite, copper, iron and steel, and silica sand processing.
These industries can generate wastewater streams with high concentrations of dissolved solids and other contaminants.
Vacuum evaporation can help industrial plants:
This makes evaporation technology particularly relevant to Indonesia’s growing mineral-processing and downstream manufacturing ecosystem.
Vacuum evaporation systems can be applied across several industries where wastewater contains high concentrations of dissolved or difficult-to-treat components.
Indonesia’s mining and mineral-processing industries are major beneficiaries of industrial downstreaming.
Processing operations can generate wastewater containing dissolved minerals, salts, metals, and other contaminants. Vacuum evaporation can concentrate these streams and help recover water for reuse.
Chemical plants frequently deal with wastewater containing solvents, salts, acids, alkalis, and other process chemicals.
A properly designed evaporation system can help separate water from concentrated residues and reduce the volume requiring further treatment.
Food-processing facilities generate wastewater containing organic matter, dissolved solids, cleaning chemicals, and process residues.
Evaporation can be used in selected applications for wastewater concentration, product recovery, and water reuse.
Pharmaceutical wastewater can have complex compositions and may contain dissolved active ingredients, solvents, salts, and other compounds.
Vacuum evaporation can provide a controlled thermal separation process for suitable high-strength wastewater streams.
Indonesia is one of the world's major palm oil-producing countries, making palm oil processing an important industrial activity.
Wastewater streams from palm oil and oleochemical operations can contain significant organic loads and dissolved materials. Depending on the wastewater characteristics, evaporation can form part of a broader treatment or concentration system.
Textile production can generate wastewater containing dyes, salts, chemicals, and high levels of dissolved solids.
As Indonesian textile facilities face increasingly structured wastewater requirements, advanced treatment technologies can become valuable for difficult or concentrated wastewater streams. Indonesia has specifically introduced wastewater quality regulations for textile activities.
Zero Liquid Discharge (ZLD) aims to minimize or eliminate liquid wastewater leaving an industrial facility by recovering water and concentrating the remaining dissolved materials.
A typical ZLD configuration may include:
Feed Equalization & Pretreatment
↓
Clarification / Filtration
↓
RO or Other Membrane Concentration, Where Applicable
↓
MEE / MVR / Vacuum Evaporation
↓
Distillate Recovery & Polishing
↓
Concentrate Evaporation / Crystallization
↓
ATFD / Dryer, Where Required
↓
Dry Solid Residue
Vacuum operation lowers the boiling temperature of water. This can make evaporation possible at lower temperatures than atmospheric evaporation and can be advantageous when integrating the evaporator with heat recovery or when treating temperature-sensitive streams.
The exact configuration depends on wastewater chemistry, flow rate, concentration, scaling potential, required recovery rate, and energy availability. Not every ZLD plant requires every stage; the configuration depends on wastewater chemistry, flow rate, recovery target, scaling potential, and final residue characteristics.
The Indonesia market for industrial vacuum evaporation systems is supported by growing industrial wastewater treatment and water-reuse requirements, but adoption can be constrained by high investment costs, energy requirements, technical complexity, and limited specialized expertise. Indonesia's wastewater requirements can also vary by industrial activity, discharge route, location, and applicable approvals, making system selection and compliance more complex.
Industrial vacuum evaporators, particularly MVR and multi-effect systems, require significant upfront expenditure for evaporators, heat exchangers, vacuum equipment, pumps, controls, and installation. This can make adoption difficult for SMEs and cost-sensitive manufacturers.
Evaporation is inherently energy-intensive. Although MVR and heat-pump technologies can substantially improve efficiency, electricity and thermal-energy requirements remain an important consideration when evaluating the total cost of ownership.
Vacuum evaporation requires precise control of temperature, vacuum pressure, feed concentration and vapor separation. Poor operating conditions can reduce efficiency and increase downtime, creating challenges for facilities without experienced technical teams.
Industrial wastewater can contain high concentrations of salts, suspended solids, oils and aggressive chemicals. These can cause scaling, fouling and corrosion of heat-transfer surfaces and other components, reducing heat-transfer efficiency and increasing maintenance requirements.
Vacuum evaporation competes with technologies such as reverse osmosis, nanofiltration, conventional wastewater treatment and other ZLD solutions. For wastewater with relatively low salinity or lower fouling potential, membrane-based systems can sometimes offer a more economical solution.
Indonesia does not have a single wastewater standard applicable to every industrial facility. Requirements can depend on the industry, wastewater source, discharge/reuse route, location and technical approvals. This can increase the complexity and cost of designing an evaporation-based treatment system.
Industrial wastewater characteristics can vary significantly depending on production processes. Changes in TDS, COD, pH, suspended solids and chemical composition can affect evaporation performance and require customized pretreatment and system design.
These factors are particularly important in Indonesia because manufacturers need to balance advanced wastewater treatment and water-reuse objectives with overall lifecycle cost and operational reliability.
The appropriate evaporation technology depends on the feed flow rate, composition, TDS, viscosity, suspended solids, scaling tendency, heat sensitivity, required concentration, water-recovery target, available steam and electricity, and operating pressure.
Evaluate TDS, COD, pH, suspended solids, dissolved salts, organic content, viscosity, volatility, and scaling potential before selecting the evaporator.
The evaporator should be sized according to feed flow rate, evaporation load, operating hours, turndown requirements, and future capacity expansion.
The target final concentration and required water recovery determine the number of effects, evaporation duty, downstream crystallization or drying requirements, and overall system configuration.
Steam, electricity, waste heat, and cooling-water availability should be evaluated when deciding between conventional evaporation, MEE, MVR, TVR, or hybrid configurations.
Wastewater containing high concentrations of salts, silica, hardness, organics, or suspended solids may require pretreatment and an evaporator configuration specifically designed to manage fouling and cleaning requirements.
Vacuum level, vapor load, condensable load, gas composition, and operating temperature should be considered when selecting the vacuum pump and condenser arrangement.

Pilot testing can help establish evaporation rate, heat-transfer performance, scaling tendency, concentrate behaviour, achievable final concentration, distillate quality, energy consumption, and cleaning requirements before full-scale equipment is designed.
“For difficult or variable wastewater streams, pilot testing using representative feed samples can reduce scale-up uncertainty and help determine the appropriate evaporator configuration.”
ECOPROCESS engineers and manufactures customized evaporation and vacuum process systems based on feed characteristics, evaporation duty, required concentration, vacuum level, utilities, materials of construction, and plant operating conditions. Its engineering approach integrates process engineering, vacuum technology, evaporation, drying, heat transfer, instrumentation, automation, materials engineering, fabrication, and commissioning.
The engineering scope can include:
This enables a project to be developed around the complete process rather than treating the evaporator, vacuum pump, condenser, and controls as independent components.
A typical project can therefore progress through:
Process Assessment → Laboratory/Pilot Testing → Process Design → Evaporator Selection → Vacuum System Design → Heat & Mass Balance → Equipment Engineering → Fabrication → FAT/SAT → Installation → Commissioning → Operator Training → Lifecycle Support
This approach is particularly valuable for industries dealing with complex feed streams, high-TDS wastewater, corrosive materials, heat-sensitive products, solvents, viscous liquids, or ZLD requirements.
ECOPROCESS combines:
For companies evaluating an industrial evaporator, vacuum evaporation system, MEE/MVR system, or ZLD evaporation plant, ECOPROCESS can assess the process requirements and develop a technology configuration around the specific feed, capacity, utilities, recovery objectives, and operating conditions.
A vacuum evaporation system concentrates liquids by operating under reduced pressure, lowering the boiling temperature and allowing water or other volatile components to be removed at comparatively lower temperatures.
Potential applications include chemicals, pharmaceuticals, agrochemicals, food and beverage, palm oil processing, petrochemicals, mining and mineral processing, battery-material manufacturing, textiles, and wastewater treatment.
Vacuum evaporation is particularly suitable for selected high-TDS, high-strength, concentrated, difficult-to-treat, or water-recovery applications where conventional treatment or membrane systems alone may not achieve the required concentration or recovery.
MEE (Multiple Effect Evaporation) reuses vapor generated in one effect as the heating medium for the next effect, reducing steam consumption compared with single-effect evaporation.
MVR (Mechanical Vapor Recompression) compresses secondary vapor mechanically and reuses it as heating vapor, significantly reducing the requirement for external steam in suitable applications.
TVR (Thermal Vapor Recompression) uses high-pressure steam to thermocompress part of the secondary vapor and return it as heating vapor.
Yes. Vacuum evaporation can form an important part of a ZLD train. Depending on the wastewater characteristics, it may be combined with pre-treatment, membrane concentration, MEE/MVR, crystallization, and ATFD or other drying technologies.
The selection should be based on feed flow rate, composition, viscosity, TDS, solids, heat sensitivity, scaling tendency, required concentration, water-recovery target, available utilities, and operating conditions. Pilot testing can be used to validate the design before full-scale investment.
Indonesia’s expanding manufacturing, downstream processing, mining, chemical, food, pharmaceutical, palm oil, and textile industries are creating increasingly complex wastewater-treatment requirements. As industrial facilities seek to reduce wastewater volumes, recover water, manage high-TDS streams, and support Zero Liquid Discharge (ZLD), vacuum evaporation systems are becoming an important option for suitable applications.
However, selecting and implementing the right evaporation technology requires careful consideration of feed characteristics, energy consumption, scaling and fouling risks, regulatory requirements, recovery targets, and lifecycle costs. A customized engineering approach can help industries achieve reliable performance while balancing treatment objectives with operational and economic requirements.
