When rivers run dry
Rivers and lakes are polluted and an increasing number of people have to rely on well-water for drinking.
Some of the new wells contain Arsenic, Fluoride, Uranium, Radon, Aluminum, Copper, Cadmium, Barium, Lead, Manganese and other minerals in concentrations that are poisonous in the long run. These minerals that have been there before, but the water has not been used for drinking before.

More than one billion people now drink water that is more or less poisoned by natural minerals.

Water Worries?
Dr. Nandita Basu from the University of Waterloo, Canada, reported her scientific findings about nitrates in all of our drinking water, which is directly linked to thyroid cancer, birth defects and even the infant blood disorder named Blue Baby Syndrome. The nitrates come from the nitrogen fertilizers used in commercial farming over the decades. When examining a variety of water basins from the central to south U.S., a minimum of ten inches to a maximum of three feet of this accumulated chemistry settles at the bottom of these waterways. If we immediately stopped using these disease causing chemicals, it would require a minimum of thirty years to diffuse their danger.

Flint, Michigan, and its notorious lead in the water scandal has provoked public awareness about the potential that multiple sources of H2O may contain. When reading the literature that is sparingly available, we should all be alarmed. Flint is an example of many towns, cities and villages worldwide.
Lead, of course, damages the brain and nervous system, but how about the other heavy metals — chemicals, poisonous organic matter and microbes that often call our drinking water their home? All of these killer compounds come from one industry or another—chemicals and heavy metals from manufacturing, organic compounds, excrement, viruses, bacteria and amoebas from animal factory farming ,etc.— and they all cause disease.
One water expert says Flint's drinking water is no worse than tens of thousands of public sources globally.
In spite of a profound discovery nearly fifty years ago that the very chlorine that is added to public drinking water systems for the purpose of stopping the mass cross-contamination of bio- logical foes also leaches from the very pipes it runs through. Although there are regional differences, 22% of the pipes in the U.S. alone are more than fifty years old. On average, these pipes fail after 47 years of use.
Of course, European, Asian and other ancient settled parts of the globe endure much older infrastructures, causing even greater problems. Chloroform is another unintended consequence of using chlorine to kill infectious disease in our water systems. Natural organic compounds, when mixed with the chemical chlorine, creates cancer causing chloroform. It is assumed that all water that has this noxious element added to it raises the chance of consumers contracting one or more of a wide variety of malignancies.

Shampoo in the water supply triggers growth of deadly drug-resistant bugs
Household cleaning products are creating a bacterial timebomb in our drains and rivers

Fabric softeners, disinfectants, shampoos and other household products are spreading drug-resistant bacteria around Britain, scientists have warned. Detergents used in factories and mills are also increasing the odds that some medicines will no longer be able to combat dangerous diseases.

The hazard of nanoparticles
The hazard of nanoparticles has been noted lately. In the water treatment industry there are no known methods to efficiently purify water from nanoparticles. We have therefore commissioned KTH make an initial test on the removal of silver nanoparticles. It has been successful. We now continue the tests with other types of nanoparticles.

Nanoparticles can penetrate through the skin into the blood and bring other toxic molecules along. Health and environmental effects are largely unknown.
The human cell is approximately 5 micrometer in section - thus 5 000 nanometers. A nanoparticle therefore penetrates easily through the cell membrane and could possibly cause harm.

One of HVR’s projects gets top marks in report to Sida
Sida has ordered a consultancy in order to find new project ideas for development co-operation in Bangladesh. The consultancy was carried out by SIPU International AB - http://www.sipu.se/international in co-operation with
Adam Smith International - http://www.adamsmithinternational.com/ and
ORGUT - http://www.orgut.se/.

The report gives HVRs project a total mark of 19 of 20.

“In terms of potentially responding to the Sida result area 3 regarding improved access to drinking water and sanitation for vulnerable groups, this project seems to be a particularly strong candidate for a Sida PSC”… and describes it in the following way “A Swedish research-based company has invented and developed a method that can remove not only arsenic but also bacteria and saline content, and it has produced several prototypes that have been tested. From what can be understood from documentation - including independent sources - this is a unique method, based on membrane technology, to produce clean water, which has not been doubted nor contested…. Also Grameen Shakti (a subsidiary of the Grameen Bank), participates in this study, having expressed its interest to market the equipment in the future. Their business idea is to develop community size equipment that would produce biogas and fertilizer from manure and other biomass. The biogas would be used to run an engine, which runs a generator to make electricity. The coolant from the engine runs a membrane distillation module which produces arsenic free water.”

PSC = Private Sector Collaboration

Workshop in Dhaka regarding removal of arsenic from drinking water
KTH is arranging a workshop regarding its Bangladesh project on 20th Oct, 2014.



Various stakeholders have been invited for a policy dialogue in Dhaka covering government, NGOs. Developmental partners, Micro finance institutes, biogas developers, Universities etc. (around 40 participants).


The project is carried out in co-operation between HVR, KTH and Grameen Shakti with financial support from Sida. Included is a short presentation of the proposed technology.


Whoever wants to participate in the workshop or send a representative should contact
Dr Brijesh Mainali at brijesh.mainali@energy.kth.se


If the person needs visa, an invitation letter can be provided from the project side and also from Grameen.


The title of the workshop is: Solutions to provide clean energy and safe drinking water in rural areas – Opportunities based on biogas and poly-generation



The venue is:

Grameen Bank Auditorium

Grameen Bank Bhaban

Mirpur-2

Dhaka-1216

Bangladesh




Date: 20th Oct, 2014

Time: 9.00 to 15:00

HVR co-operates …
HVR co-operates with the Royal Institute of Technology in Stockholm, Sweden and CSEM-UAE (Centre Suisse d' Electronique et de Microtechnique United Arab Emirates) in Ras Al Khaimah, UAE, in the development of a solar desalinator/ water purifier. A progress paper was presented at a conference arranged by the International Solar Energy Society (ISES) - the Solar World Congress in Cancún, Mexico in November, 2013.

HVR is launching the model Elixir 500
HVR is now launching the model Elixir 500. This model successfully combine the
advantages of efficient thermal processes with membrane distillation to a very small modular configuration. It is developed for purifying water to drinking water with >99% purification efficiency with a nominal capacity of 20 litres per hour or 500 litres per day. The product is suitable for installation in multiple households, larger individual house-holds, or installations where demand of drinking water is 20 litres per hour. Elixir 500 works without expensive filter changes, and offers the consumer a reliable and trouble – free method to produce absolutely pure drinking water. The water is free from harmful contaminants – irrespective of initial water quality. The pay off time is short. In addition, Elixir 500 also desalinates seawater. In countries where tap water is unfit for drinking and cooking purposes, Elixir 500 is a competitive alternative to bottled water. Elixir is designed to work with solar / biogas or waste energy

New strategy in HVR
HVR has now established a new business strategy. Previously, activities were focused on selling its products as counter top units directly to consumer markets.
The new strategy means the company will establish partnerships with major companies in Europe, Asia and North America that produce residential products for heating and cooling. HVRs products will consist of a customized module unit in such systems with generating clean drinking water in conjunction with the other features of the systems.
