Because ferric chlori火日de is widely used, liquid ferric c司湖hloride is an efficient 工生and cheap flocculant for the 那綠treatment of urban sewage and indust土子rial wastewater. COD and BOD.

Compared with other wastewater treatme笑個nt flocculants, its main characteris化土tics are as follows:
1、It is more than 40% lower than th購議e price of solid ferric chl坐來oride (same concentration) and can近能 completely replace solid ferric chlo飛唱ride;
2、It is an aqueous solution, whi高生ch eliminates the operation of soli慢家d preparation solution an知男d the problem of incomplete弟用 dissolution;
3、Replace liquid or solid aluminum su煙體lfate, polyaluminum chloride,金樂 polyferric sulfate and o笑場ther flocculants, redu中科ce the processing cost by more 小靜than 30%;
4、excellent flocculation p是制erformance, settling speed i冷區s higher than aluminum房資 salt series flocculants 中報(such as aluminum sulfate, polya跳生luminum chloride, etc.), 微好and the formation of dense alum fl麗是owers;
5、The amount of generate習匠d sludge is small, which greatly匠街 saves the cost of sludge 一場treatment;
6、It has a wide range of PH value喝煙 to adapt to water bo多見dy, it is 4-12, and the optimal p能子H range is 6-10。
