Three countries, one technology,
one network.
VÆLARUM is not an outside distributor. It is the German leg of an existing international network built around Gilles Galichet's invention.
What we do
We deploy technologies that retrofit existing wastewater treatment plants and sedimentation tanks. They act on flow conditions and material concentrations, without intervening in the building structure.
The effect is documented over multi-year real operation: higher hydraulic capacity, improved effluent quality, lower energy demand, reduced operating costs. The retrofit itself is modular, with short installation time, no operation interruption.
The network
Densiline FR
Origin of the invention. Gilles Galichet developed Speed-o-Clar®, holds the patent and runs the original fabrication. Over 60 plants are retrofitted in France.
Densiline CL
Latin-American leg in which the Oehr family has been engaged for years. Two plants retrofitted, others in the planning pipeline.
VÆLARUM (in formation)
Newest element of the network. Industrial scale-up of fabrication via additive manufacturing. Manufacturing partner for the German market.
Management
The designated Managing Director is Arvid Oehr. Formal appointment takes place with the registration of the GmbH in the commercial register.
Arvid Oehr leads the strategic direction of VÆLARUM, customer and partner relations, and the further development of the manufacturing technology. He brings the connection to the existing international Densiline network into the German company.
Speed-o-Clar® partnership
VÆLARUM is the designated manufacturing partner for Speed-o-Clar® in Germany. The formal agreement with patent holder Gilles Galichet is fixed in writing alongside the GmbH registration.
The partnership covers the use of Speed-o-Clar® technology for the German market, fabrication via additive manufacturing, and the engineering support of pilot projects and roll-outs at German wastewater plant operators.
How we work
Structural choices that distinguish our work from a conventional commercial approach.
Complementarity, not competition
Our effect amplifies that of other providers — pumps, sensors, biological process control, automation. They are not competitors but complementary actors in the same value chain.
Regulation as a structural advantage
High regulatory density defines an action space with clear contours. Those who understand regulatory structures in depth — not merely formally — gain a position others reach only at high cost.
Inclusion as a productive factor
Expertise from groups whose knowledge is otherwise hard to access — experienced professionals, returners, people with physical limitations. Telepresence and tele-operated robotics take location and physical resilience out of the equation.
Scientific validation
Advice built on named, validated knowledge modules carries different weight than advice based on experience alone. Institutionalised cooperation with domain experts and research bodies — validation in exchange for publication rights and named attribution.
Methodical knowledge building
First needs clarification, then domain-specific knowledge, finally verification against standards and regulations. Broad orientation, then targeted depth. Depth developed only where it is actually needed.
Awareness, not advertising
Demand often arises from events the operator does not see — extreme weather, demographic shifts, changing wastewater composition. We show the implications for defined plant types, without pushing.
Values and way of working
Engineering before marketing
We do not claim figures we cannot substantiate. What is a planning assumption is marked as such. What is a verified measurement has a source.
Closed loop
Material we install should, at end of life, return as raw material into our printer. rHDPE is not a fallback — it is a design principle.
Remote before travel
If LiDAR, CFD and 3D printing can deliver a solution before anyone boards a flight — no one flies. On-site only for installation.
Data sovereignty
Survey data from wastewater plants is critical infrastructure data. Where classified accordingly, processing is fully offline, with no cloud service involvement.
Vision — where we are going
Implementation is sequential. What is demonstrable starts first: founding, first pilot installations, gradual broadening of the reference base. Each step has defined transition criteria to the next.
Extensions — inclusion component with telepresence, strategic partnerships, knowledge layer from anonymised operating data, expert-validation structure, awareness channels — are activated as soon as the prior layer holds. Not in parallel with the founding phase.
Geographic extension follows the same logic: national legal form first, then a public limited company, then a European legal form with a subsidiary in another EU state.
The order is a working assumption, not a rigid plan. What proves viable in any phase determines what comes next.
Location
Headquarters and manufacturing in Germany. The exact address will be published with the commercial-register entry. in formation
Careers
VÆLARUM is being built. Open positions will be published after GmbH registration with a clear, SFIA-based role description — applicants should know which competencies are expected and at what level of responsibility.
We seek expertise where it is otherwise hard to access: experienced professionals with long careers, returners after family or health breaks, people with physical limitations, people whose life circumstances rule out classical on-site full-time models. Telepresence and modular tooling are designed to take location and physical resilience out of the equation.
