CHEMICAL PRODUCTION OF ACIDS AND BASESProcess Feasibility Assessment
Are you looking into building a full-scale separation system for your industrial plant? At Lenntech, we can offer you a feasibility study for a system that responds to your specific need. We accompany you through each step of the way, from conceptualization of your idea to the supply of the final integrated process.
Lenntech Water Treatment Solutions has 30 years of experience in the field of water treatment and separation processes. We practice at the cutting edge in the field of purification and recovery and implement innovative solutions to respond to our customer’s demands. To this aim, we supply a broad range of technologies to meet the desired effluent compositions and quality requirements. Key technologies, applications and industries include:
Pressure driven technologies
Electrically driven technologies
Ion exchange
Non-ionic sorption
Solutes separation or concentration
Solutes recovery
Stream deacidification or desalting
Brine minimization
Water reuse or discharge

Chemical
Energy
Food & Beverage
Pharmaceutical
Textile
SIGNIFICANCE
Our R&D feasibility study allows to:
- substantiate the performance of a proposed system
- collect operational and design parameters
- confidently move forward to the engineering of your full-scale system
- Recently, we observe a growing need of the industries for custom-made solutions targeting unconventional water streams. For these streams, moving directly towards a system design is too risky, as it involves a number of assumptions that still require validation.
- Assessing the feasibility of a process avoids future full-scale troubles, such as a non-adapted design, lack of performance, and additional financial costs.
APPROACH
Technology(-ies) Preselection
Together with you, our R&D team performs a preliminary assessment of your request based on your stream composition and main treatment objectives. By combining our expertise, scientific knowledge, and problem-solving mindset, an initial selection of most promising and technology(-ies) is made.
Laboratory Proof-of-Concept
During our laboratory proof-of-concepts, we conduct experiments on bench-scale set-ups to assess the feasibility of the preselected separation processes, and to optimize the process before moving to larger-scale installations. This evaluation is preferentially carried out on a representative sample of the industrial stream. This way, we can evaluate the need for pre- or post-treatments, and anticipate potential difficulties linked to the presence of other solutes or suspended solids.
Pilot-scale Assessment
When the outcomes of the laboratory Proof-of-Concept are favorable, pilot-scale tests allow to evaluate the scalability of the separation process before proceeding with the full-scale design. This is an important step in the treatment assessment, during which we validate the process configuration and design parameters. From there and together with our process and project engineers, we make a detailed offer for your full-scale plant.

We provide a first theoretical analysis of concept for free if we see possibilities for treatment.
As second step we can do a lab scale/bench sale test with a sample for a proof of concept (POC) feasibility study providing budget costs and parameters after which we could scale-up the process/technology to pilot and or full-scale.
