Jobs and Internships

• As a Mechanical and Plant Engineer you will have the opportunity to design systems for a new and versatile water treatment technology. Your task is to plan the systems based on a specification sheet, select components, prepare parts lists and supervise commissioning. Documentation in the form of flow charts is naturally part of the job and you will work closely with the electrical planning department. Your goal is to build robust and user-friendly plants for the recovery and recycling of resources from industrial wastewater and to bring them to market with us.

Your job profile will include:

• Design of systems for the operation of membrane distillation modules.
• Responsibility for project management as well as planning-construction order processing of the systems
• Preparation of technical specifications and support in the procurement of plant components
• Communication with customers and suppliers
• Sales support in the preparation of technical quotations
• Support in the construction of the plant

As a development engineer at SolarSpring you will have the opportunity to develop, produce and test a unique and future-oriented product for our customers. On the way to series production, the first prototypes will be manufactured in our production hall in cooperation with our production partner.

The job profile includes:

• Production of membrane modules
• Set-up and optimization of production
• Working on R&D topics in module construction
• Testing of the modules
• Implementation of an appropriate quality management

Your profile:

• a degree in the technical field
• a conscientious, precise and independent way of working
• reliability, sense of responsibility, ability to work in a team and flexibility
• very good written and spoken German (minimum B1). English knowledge is an advantage.
• manual dexterity and experience in handling tools
• driving license class B

For the expansion of our marketing activities we are looking for an employee (m/f/d) on a part-time basis.

Your tasks:

• Maintenance of the social media channels (focus on LinkedIn and Twitter).
• Active participation in the planning and implementation of online marketing activities
• Coordination of ad requests, creation of printed materials and advertising materials
• Maintenance and further development of the homepage
• Carrying out trend and market analyses and research
• Coordination of the newsletter

Your profile:

You are open to new challenges and enjoy working independently, in a structured manner and on your own responsibility. You bring your own experience and ideas to your work and appreciate a team-oriented mindset. We require a completed vocational training, a degree or comparable work experience in marketing. You have very good analytical skills and a quick grasp as well as good knowledge of MS Excel, PowerPoint and Word. A good feeling for language and text reliability in several languages (at least German and English) is important to us. Knowledge in search engine optimization is an advantage, as well as the willingness to deal with the technical topics of our products.

R&D Membrane Distillation | Final Thesis
within the scope of a 6-month internship

Your motivation:
SolarSpring GmbH and is an internationally active company in the development of modules and systems for membrane distillation (MD). The application of the process in seawater desalination has been well researched within several, publicly funded projects in the last years and tested by pilot systems in the field. Now, the potential of membrane distillation is to be considered and evaluated for other application areas as well, in order to be able to address the new requirements with adapted module concepts.

Your tasks:
Membrane distillation is a hybrid process, which is positioned between membrane processes and evaporation processes. It has a hydrophobic membrane as a physical separation boundary through which mass transport can only pass in gaseous form. As with the evaporator processes that have been in use for many years, there are different methods of heat recovery within the system.

Many industrial processes generate considerable amounts of wastewater containing high concentrations of inert salts. The discharge of high salt loads into surface waters represents a major burden on the ecosystem, especially if they are used for drinking water production. Efforts are therefore needed to reduce salt loads. Against this background, from the industry’s point of view, there is a need for action to research and develop new, environmentally friendly and economically viable processes for the purification, desalination and utilization of salts or purified concentrated salt solutions.

One possible solution is concentration with membrane distillation. Since this application brings new requirements for the technology, a series of basic investigations are necessary, which primarily relate to increasing the process efficiency using vacuum. An existing test rig has to be modified and commissioned for this purpose in order to investigate and evaluate the resistance of the membrane materials to unwanted wetting.

The work is designed to take 6 months to complete. Practical knowledge in handling tools and an independent and self-reliant way of working are absolute basic requirements for this task.

You would be responsible for the supervision of a membrane distillation plant for the conversion of ammonium into ammonium sulfate

Motivation

SolarSpring GmbH is an internationally active company in the development of modules and systems for membrane distillation (MD). The application of the process in seawater desalination has been researched within several, publicly funded projects in the last years and tested by pilot systems in the field. Now, the potential of membrane distillation is to be considered and evaluated for other application areas as well, in order to be able to respond to the new requirements with adapted module concepts.

Technology

Membrane distillation is a hybrid process that is positioned between membrane processes and evaporator processes. It has a hydrophobic membrane as a physical separation boundary through which only gaseous substances can pass. As with the evaporator processes that have been in use for many years, there are different methods of heat recovery within the system.

Task

Every day, municipal wastewater treatment plants treat wastewater from households and industry. A major challenge in this process is ammonia, which is harmful to the environment. At Solar Spring, we have developed a process that extracts ammonia from the digested waste. Not only is the ammonia removed from the wastewater, but it is also used to produce a nutritious fertilizer for agriculture. The process is now ready for the next large-scale implementation. Here, at the beginning of the internship, you would supervise the construction and installation of the plant at our company and later at the Erbach wastewater treatment plant. Once set up on site at the sewage treatment plant, the following activities are on the agenda:

Planning and conducting experiments
Monitoring and evaluation of the plant
Regular spectroscopic and chemical analyses of samples
Troubleshooting and troubleshooting of the plant

Requirements

Bachelor degree in environmental engineering, process engineering, mechanical engineering or chemistry
Independent working style and solution-oriented approach
Language skills: German
Driving license class B

The internship is designed for a full-time position of 6 months, starting at the beginning of June and will mainly take place at the site of the wastewater treatment plant in Erbach. The internship is to take place in cooperation with another student:in. A joint application with one of the students is possible. The internship will be remunerated.
