For the first time, experiments with nanotechnology were successfully carried out by passing another step in Ran Kendiya Medicinal Clay Water Filter. This was done under the full supervision of Prof. Rohini de Silva and Prof. Nalin de Silva from the Department of Chemical Sciences, University of Colombo. This will be able to provide a successful solution to the problem of providing clean drinking water which is a major problem facing the people of Rajara. We are also happy to inform you that we were able to successfully remove arsenic, bare metal, and hard water.
We would like to express our thanks to Prof. Rohini de Silva and Prof. Nalin de Silva of the Department of Chemical Sciences of the University of Colombo for contributing to the further development of the quality of our water filter and joining us with this experimental program. let’s stay.
This is the outcome of our NRC mega grant project. We produced 3 PhDs and most importantly we achieved the target we promised during the grant applications and evaluation. We worked with this small company to develop prototypes. Our pledge was to develop an environmentally friendly water filter to be used in CKDu-affected areas. We had obstacles as no one helped us to find any partner to develop a commercially viable filter. Our Ph.D. students worked hard to find a partner to develop this. We found this company. The gentleman in the picture is the owner of the company and he is a very innovative person who listened to all our suggestions and helped to develop the prototypes now the product is on the table in CAMD. He is absolutely easy to work with as both parties were least interested in financial matters. We are working with NRC and a Chemical Engineer to scale up the process. We are very happy to see a local business gets the technology edge through our intervention. Our happiness is to see that one day these filters will reach people in the affected areas. These are specifically designed to remove heavy metals, fluoride, and also hardness which are the key factors associated with the CKDu problem in the north-central province of the country. Biocompatible advanced materials are used and even toxicity studies of these nano-materials were done using live zebrafish models in the department of chemistry.
