Q3 Report 2022

Household appliances

During the quarter, HVR has initiated contact with various prospective partners and stakeholders for the manufacture and distribution of future products with an emphasis on a household appliance. Several well-known brands have been able to open their doors. HVR has several previous prototypes behind it, the work to be able to produce an updated market-adapted product is ongoing. Research and development as well as design is done in close collaboration with Hydromars, which is based on HVR’s previous product development. Some technical advantages have already been identified as Hydromars develops a prototype for the space station ISS.

HVR’s Demo facility Odisha/India Primary School in Balasore

The facility is living and working proof that our technology cleans water even from highly polluting sources (fluorides in the school’s case). Professor Urban Rydholm and senior physician Rabi Dash from ISRF (Indo-Swedish Rheumatology Foundation) would like to continue developing a fruitful interdisciplinary collaboration and plan medical research and follow-up of the children’s health together with regional medical universities.

During the period, the first phase of automation of the pilot plant was carried out. The last part is prepared and planned to be installed after the monsoon period at the end of September. The goal is to be able to make the plant’s production of healthy drinking water more efficient and make the school independent in its supply. HVR can then model the installation, using proven experience and data to further commercialize the product. The product is the basis for HVR’s ongoing application to the EIC accelerator’s 2022 funding program.

Three master’s students in collaboration with KTH

HVR Scientific expert Ershad Khan has been the industrial supervisor for three master students from KTH, Sweden and IST, Portugal. The chosen subject in the theses was based on the Odisha pilot plant to study solar energy techniques, automation, and life cycle analysis. Three student’s thesis titles and objectives.

Zanil Narsing, Instituto Superior Técnico IST, Lisbon Portugal

Thesis title: Techno-economic analysis for a stand-alone membrane distillation water purification system using concentrated photovoltaic thermal (CPVT) technology.

The objective of this master’s thesis is to determine the most cost-optimal standalone design for HVR Water Purification AB’s membrane distillation technology through a techno-economic analysis.

Erik von Schultz, KTH

Thesis title: PVT collector coupled heat pump system for driving water purification in rural Indian community.

The aim of this project is to evaluate the feasibility of a PVT+HP+MD off grid system with both electrical and thermal storage in rural India, based on a techno-economic performance analysis with regard to local prerequisites.

Sharang Kolathur, KTH

Title: Life cycle assessment of a water purification system.

The objective of the thesis is to develop a dynamic LCA model for the Odisha system along with a general template that can be used to evaluate the environmental impact of such a system when installed in other parts of the world.

Hydroponics a new market opportunity for HVR

During the quarter, HVR also drew attention to the bubbling hydroponic market (circular vertical farming without soil), which is seen as an opportunity for future HVR products. Some producers have been visited and advanced contact has been developed with researchers in the subject. A HVR unit can have a significant role in this type of precision cultivation because the tightest control over the water quality is crucial for the quality and circularity of hydroponic cultivations.

Tap water used in hydroponics can vary in quality. No later than 22 September 2022 AFP Vanessa Meyer reported according to a Le Monde data collection that 20% of the French population (about 12 million) are exposed to drinking tap water that contains pesticide residues above legal quality limit levels.

HVR’s technology can enable local production of fresh vegetables and spices in the safest way with the least impact on the climate.

HVRS research facility IVL Hammarby Sjöstadsverket is being moved

HVR’s research facility has been dismantled and is planned to be rebuilt during the first quarter of 2023 at Louddens Reningsverk, which is owned by Stockholm Vatten. The unit produces ultra-pure water since 2010 using district heating energy and has been the subject of various studies and tests that could prove, among other things that HVR cleaning coped with chemical residues that cannot be removed with traditional cleaning.

Novel HVR technology breakthrough for treatment of forever chemical PFAS in landfill leachate

In a study project commissioned by the Swedish Geotechnical Institute (SIG) which was run by HVR scientific expert Ershad Khan in collaboration with the Swedish University of Agriculture (SLU), it has been proven that all kinds of PFAS are cleaned away. For most of the PFAS 26 compositions analyzed, the concentration in the permeate water was very low or below the detection limit. The results showed that the total removal rate of PFAS 26 >99.5%. Moreover, the corresponding yield of recovered permeate water was >80%.

Title of the project: ”Treatment of per- and polyfluoroalkyl substances (PFASs) in landfill leachate using novel membrane distillation (MD) technology”.
