1. Experimental principle and purpose:
This equipment can carry out various physical, chemical and physical and chemical comprehensive treatment process experiments. The experiments include:
1. Filtration experiment: Sand filter material can be used for filtration (including backwash intensity experiment);
2. Activated carbon adsorption experiment: (the adsorption performance of activated carbon of various types and grades can be tested);
3. Ion exchange experiment: Resin can be used to exchange the hardness in water, and the exchange performance of various grades of resin can also be tested (regeneration outside the tower); The
reaction columns of this equipment can be connected in parallel to operate, or they can be decomposed into multiple sets for multiple groups of students to conduct separate experiments. This device can open seven or eight basic experiments in water treatment and chemistry.
