Comparison and discussion of salt sludge filter press equipment

In the process of producing pure alkali by ammonia alkali method, it is necessary to dissolve the solid salt, remove the impurities in the salt by adding grey emulsion, and make fine brine, and then send it to heavy alkali plant to make alkali after clarification. After clarification, it is sent to the heavy alkali plant for alkali production. Salt sludge and impurities generated during the clarification process are sent to the denitrification filter for dewatering to reduce the water in the salt sludge ...
