Technologies for preparation of drinking water from the low power surface water source

The problem of providing small settlements with drinking water is important. The sources of small capacity can be used for this purpose. The quality of water in the ponds of a small capacity varies greatly during the year. The concentration of phytoplankton depends on the season of the year, and this is the main problem when using sources of small capacity. Currently, such mechanisms have not been studied properly. Water filtration is used for the preparation of drinking water from small capacity sources. The methods of water's treatment with chlorine are also used. The use of fine filtration technologies is costly in operation. The research of phytoplankton's detention was carried out on the floating filter. The floating filter is made of polystyrene. The study of the effectiveness of seaweed detention showed that the reduction of rising flow improves the quality of water purification. The subsequent stages of the water treatment involve the use of oxidizing agents. The technological scheme of water treatment from reservoirs of small capacity has been developed. The specifics of the technology's functioning for water sources of low capacity has been established. © Published under licence by IOP Publishing Ltd.
