The operation of supply water and drainage systems when there are rain on the salt producing fiel for to take the more effective in the salt production with high quality

Abstract

     There are 21 provinces producing salts in the whole country. The total are for producing salts is 11,226 ha with the average yield of 56 tons per ha. The potential for salt production in Vietnam is very high. There are 2 methods for salt production: Method evapour from table of condensed salt water and method evapour from table of sands field.

     In the evapour process of sea water for salt production. If there are raind on the salt production field, condensed salt water will be dilute, there has been a change in the line for salt production and to thin down productivity, poor yield of salt production and dilute salt quality.

     The report introducces some main methods for define operation of supply water and drainage systems when there are raind on the salt producing field by stationary method, moving method and method of cover with canvas for to take the more effective in the salt production with high quality.
