Industrial reverse osmosis system for the production of demineralized water and ultrapure water

The ALMA OSMO VE is an industrial reverse osmosis system for producing fully desalinated water (deionized water) and ultrapure water from municipal water or well water. It is specially designed for applications that require defined water qualities —not for wastewater treatment or water reuse.

The focus is on the safe, reproducible production of deionized water or ultrapure water, adapted to the respective application and the required conductivity, TOC limit, or gas-free properties.

Typical areas of application for the ALMA OSMO VE

• Deionized water for industrial processes

• Ultrapure water for sensitive applications

• boiler feed water

• district heating networks

• cooling towers

• Electronics and wafer production

• Process water with high quality requirements

The plant is always designed specifically for each project, depending on the raw water quality and target water requirements.

summary The ALMA OSMO VE is a reverse osmosis system for producing deionized water and ultrapure water from municipal or well water for industrial applications such as boilers, cooling, or electronics production.

The ALMA OSMO VE has a modular design and can be configured for a wide range of target water qualities, from classic deionized water to high-purity ultrapure water.

Typical target water qualities

Depending on the system design, the following can be achieved:

• Deionized water with very low conductivity

• Ultrapure water for sensitive production processes

• Water with extremely low TOC values

• low-gas water (e.g., CO₂-free)

• Water with defined residual hardness or completely softened

The achievable quality depends on:

• Raw water (city or well water)

• Pre-treatment

• repolishing

• Combination of the technologies used

off.

Applications with different quality requirements

• Wafer and electronics production: highest purity requirements

• Boiler feed water: low conductivity, low gas content

• District heating networks: low-corrosion deionized water

• Cooling towers: reduced salt and hardness load

summary Depending on the design, the ALMA OSMO VE can be used to produce VE water and ultrapure water for applications ranging from boiler feed water to wafer production.

The ALMA OSMO VE is not a rigid system, but rather a modular ultrapure water system in which the individual treatment stages are precisely tailored to the desired water quality.

Typical pre- and post-treatment stages

Depending on the application, the following can be integrated:

• Activated carbon filtration (e.g., for chlorine and TOC reduction)

• Softening to reduce hardness-forming substances

• Reverse osmosis (RO) as the central desalination stage

• Membrane degassing (e.g., CO₂ and O₂ reduction)

• EDI (electrodeionization) for continuous deionized water production

• Mixed-bed filters for the highest conductivity requirements

• Polishing stages for fine cleaning

• UV-TOC reduction for ultrapure water applications

The combination depends on:

• required conductivity

• TOC limits

• gas-free

• process requirements

summary The ALMA OSMO VE can be combined with activated carbon, softening, RO, membrane degassing, EDI, mixed bed filters, polishing, and UV-TOC reduction.

Each ALMA OSMO VE is custom-designed, as municipal and well water can vary greatly (hardness, CO₂, iron, TOC, conductivity).

Design criteria

• Raw water analysis (chemical and physical)

• desired target water quality

• Operating mode (continuous/discontinuous)

• Redundancy and security requirements

• Space constraints and integration

On this basis:

• the RO design determines

• the necessary pre- and post-treatment is specified

• Defines measurement and control technology

summary The ALMA OSMO VE is individually adapted to the raw water quality and target application to ensure stable deionized or ultrapure water quality.

The ALMA OSMO VE can be supplied in different designs depending on project requirements:

designs

• Container facility (turnkey, air-conditioned)

• Rack system for installation in technical rooms

service areas

• small systems for partial currents

• medium-sized plants for production processes

• Large systems for centralized deionized water supply

The modular design allows for future expansion.

Summary
The ALMA OSMO VE is supplied as a container unit or rack system and can be designed for small partial flows up to large central deionized water systems.

The ALMA OSMO VE stands for operational reliability, flexibility, and long-lasting industrial quality.
