Abstract
Chronic Kidney Disease with unknown etiology (CKDu) is one of the crucial health issues in North Central, Uva, North Western, North, Central, and Eastern Provinces of Sri Lanka and incapacitates the kidney function. The main source for the CKDu has not yet been identified, though many scientists believed that the number of certain drinking water quality parameters is changed due to the contamination of water sources by agricultural activities. Hence, the government of Sri Lanka introduces electrically driven Brackish Water Reverse Osmosis (BWRO) plants with a capacity of 10 tones/day to supply safe drinking water for the impacted community though it is an energy-intensive process. Concurrently, a smaller version of an electrically driven BWRO plant was introduced to the rural farming community for their domestic use. However, it was not practically worked out due to various reasons such as high cost, unavailability of electrical power supply for those villages. In this study, an economical air operated domestic use BWRO plant with zero-emission was designed. This anticipated system significantly reduces the government expenditures to subsidize the water purification cost by 50% of the existing expenses. Besides, simple payback time was found to be 2.5 years, and the benefit-cost ratio to be more than 1. Evaluating the performance with the conventional values, it comprehends with more sustainable and economically viable system compared to the existing method of water purification.

The honored history of Sri Lanka reveals that the nation is very strong and healthy at all times, with maintaining a spirit of traditional life style and self-sufficient economy
Results of the cost analysis showed that AO-Brackish Water Reverse Osmosis (BWRO) plant has low cost for the manufacturing the plant, cost of product water and shorter simple payback period (SPP) as compared to that of Electrically driven BERO plant with the similar capacity of annual water consumption (Table 1)
Quality of seven major parameters in water samples obtained from 10 tons per day (10 TPD) BWRO Plant, electrically driven BWRO Plant and AO-BWRO plant were analysed based on Sri Lanka Standards (SLS) 614
Summary
The honored history of Sri Lanka reveals that the nation is very strong and healthy at all times, with maintaining a spirit of traditional life style and self-sufficient economy. Today a society becomes complex and the life style is deteriorating due to various health hazards such as communicable diseases and non-communicable diseases. The Chronic Kidney Disease of unknown etiology (CKDu) is one of the major non-communicable diseases in health sector that is prevalent in North Central, Uva, North Western, North, Central and Eastern Provinces of Sri Lanka [1]. The significant root for the CKDu has not yet been recognized [2].
