This powerpoint presentation begins by providing a brief overview of Ontario First Nations Technical Services Corporation (OFNTSC) and the First Nations Water Treatment Plants in Ontario, Canada. Small communities such as OFNTSC need to ensure drinking water systems are safe, meet regulations and comply with performance standards. Many small communities select proprietary pre-packaged plants and the water treatment fundamentals (chemistry, physics) not clearly revealed by the vendor. The purpose of the design guidelines is to increase the knowledge of First Nation administrators, government officials, decision-makers and plant operators to build a strong pool of good designers, empower trainers and plant operators, and assist in selection of proper treatment. A summary of the raw water quality vs. (some) possible treatment options is provided, along with groundwater process diagram, groundwater under the direct influence of surface water (GUDI) process diagram, conventional filtration process diagram, membrane filtration process diagram, advantages of membrane filtration, packaged plants, process diagram of emerging technology, water feasibility study considerations, and selection methodology. Includes tables.
