How you can benefit from IWAT water treatment plants

Wie Sie von IWAT Wasser-aufbereitungsanlagen profitieren können

Profiling the initial situation

To benefit from IWAT water treatment plants, a personal exchange is essential. Together, we will sketch out the initial situation, your ideal vision, potential obstacles, and challenges, all without any obligation.

We specialize in tailor-made solutions for your environmental problems and are happy to discuss your individual situation in detail.

Evaluation of the appropriate water treatment process

After our extensive analysis, we start by specifying the treatment process — tailored to your goals and the desired water quality. In doing so, we clarify the component requirements, provide an initial cost framework and define the space required for the system.

Budgeting and quoting

Now we know which IWAT products can solve your specific problem. We will now prepare a detailed proposal and set a fixed budget frame. We will deliver at the agreed cost on the agreed date.

Layout of the system

We value clear, efficient, safe and economical layout plans for your site. Our layout aims at optimal use of space and strict compliance with safety and environmental standards. As a result, improved production and maintenance processes save time and money.

The main steps of the IWAT layout process are:

  • Site analysis
  • Layout can be designed in 2D and 3D
  • Simulation and modelling of the plant
  • Fine-tuning and adjustment
  • Interface planning
Detailed engineering and interface planning

Detail engineering is the phase in which the concepts and designs created are converted into detailed plans and technical documentation. This phase includes:

  1. Preparation of detailed drawings: Installation plans, detailed drawings for equipment parts, electrical circuit diagrams and layouts for instrumentation.
  2. Calculations and simulations: Detailed calculations of process dynamics, loads, fluid and thermodynamic conditions and other critical operating parameters are carried out to validate the system.
  3. Safety and environmental testing: Safety analyses and environmental impact assessments are being deepened to ensure that the plant meets all relevant regulations and standards.
