Abstract:
OBJECTIVE:To introduce water processing treatment technology and equipment for hospital manufacturing laboratory.METHODS:According to the relevant standards recorded in China Pharmacopoeia and electric conductivity,water quality of purified water manufactured by3kinds of techniques were evaluated.The advantages and disadvantages of these techniques were compared with regard to the utilization of source water,convenience of operation,environmental pollution,and so on.RESULTS:Purified water manufactured by these3kinds of techniques all met the standards recorded in China Phar?macopoeia,best quality was obtained by the technique of combining ion exchange with first order reverse osmosis,the next in order is obtained through the combination of second order reverse osmosis with electrode ionization(EDI).The purified water could be distilled to be water for injection which meets the standard in China Pharmacopoeia.CONCLUSION:Combination of second order reverse osmosis with EDI is the optimal water processing technique considering quality of purified water,utiliza?tion of source water,convenience of operation,environmental pollution and so on.Multiple distillation technology is the main artwork to prepare water for injection.
