Industrial demineralized water systems using reverse osmosis and softening.
Reverse osmosis for the production of pure and ultrapure water

ALMA OSMO VE

Our fully automatic reverse osmosis systems are specially designed for the reliable production of demineralized water (fully demineralized water) and ultrapure water - for industrial processes with the highest water quality requirements.

The reverse osmosis systems are available pre-assembled on a stainless steel rack. For optimum system availability and extended membrane service life, the system can be extended with a softening stage if required.

To achieve particularly high levels of purity, reverse osmosis can be modularly combined with a polishing stage - e.g. using an ion exchanger, mixed bed filter or an EDI unit (electroion demineralization). This reduces the conductivity to a minimum and raises the water quality to the required level for demanding applications.

Deionized water and ultrapure water suitable for industrial applications

The ALMA OSMO VE produces fully desalinated water and ultrapure water from municipal or well water with reproducible quality. The system is not designed as a rigid, off-the-shelf solution, but is customized for each project based on the raw water analysis, the required conductivity, the TOC limit, the gas content, and the intended end use.

Pre-treatment

Stabilizing Raw Water

Activated carbon, prefiltration, or water softening reduce chlorine, particles, hardness-causing substances, and other substances, which can interfere with the operation of the reverse osmosis system.

Desalination

Reverse osmosis as the key stage

The membranes reduce dissolved salts and ions. The resulting permeate forms the basis for deionized water or further ultrapure water production.

Polishing

Tailored Water Quality Improvement

EDI, mixed-bed filters, membrane degassing, or UV treatment reduce residual ions, gases, and organic contaminants according to the intended application.

Which treatment stages can be combined?

  • Activated Carbon Filtration To reduce free chlorine, organic substances, and undesirable odors or tastes.
  • Water Softening To reduce calcium and magnesium levels and to protect the reverse osmosis system from mineral deposits.
  • Reverse Osmosis Central desalination stage for producing water with significantly reduced conductivity.
  • Membrane Degassing To reduce dissolved gases such as CO₂ or oxygen, for example, in boiler and district heating applications.
  • EDI or mixed-bed filters For particularly low conductivity and continuous or high-purity polishing applications.
  • UV and TOC Reduction For sensitive ultrapure water applications with increased requirements for organic residues and microbiological quality.

Which application requires which water quality?

  • Boiler feedwater Low conductivity, low residual hardness, and, depending on the system, additionally reduced CO₂ and oxygen levels.
  • District Heating and Heating Networks Fully desalinated and adjusted to minimize corrosion, make-up and top-off water.
  • Cooling Towers and Cooling Systems Reduced salt and hardness loads to increase the concentration ratio and limit deposits.
  • Electronics and Wafer Production Ultrapure water with very low conductivity, low TOC, and high standards for particle- and microbial purity.
  • Pharmaceutical and Sensitive Manufacturing Project-specific cleanliness levels with tailored polishing, disinfection, and quality assurance technology.
  • General industrial process water Specified water quality for rinsing, cleaning, process water, and quality-critical production steps.
Deionized Water For applications in which salts and hardness-causing substances must be largely removed.
Pure Water For industrial processes with increased requirements regarding conductivity, hardness, and reproducible quality.
Ultrapure Water For sensitive applications requiring very low conductivity, low TOC, low gas content, and additional hygiene requirements.
1–500 m³/h Specified hydraulic performance range
Rack or modular container Pre-assembled integration in the equipment room or as a turnkey container system
Cross-Flow or CCRO Project-specific operating mode depending on raw water, yield, and plant design

FAQ - Ultrapure water and deionized water ALMA OSMO VE

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
