Bottled mineral water equipment according to the actual water quality of the water source, the process of mechanical filters, dosing system, fine filtration as a pre-treatment, two-stage reverse osmosis as the host, and finally with ozone sterilization process, so that the product water to meet the national drinking water purified water "GB17323-98" standard. Mineral water equipment process can be fully automatic or manual control according to customer requirements. Bottled mineral water equipment automatic control using PLC as the core, frequency control motor, touch screen human-computer interface dialogue, operating parameters can be monitored in real time, a high degree of automation can be achieved, so that the reverse osmosis water treatment of the entire system operation is more secure and reliable, more humane.
1, bottled mineral water treatment equipment process
Considering the careful analysis of various factors, combined with the Party's actual site conditions and requirements and past engineering experience, the use of raw water pre-treatment + ultrapure water preparation + ultrapure water recycling process as the main body of the high-purity water treatment process, the water can meet the national drinking water purified water "GB17323-98" water quality standards.
Bottled mineral water equipment process is as follows:
Raw water → raw water tank → raw water pump → flocculant device → dual media filter → activated carbon filter
→ plate heat exchanger → scale inhibitor device → 5μm security filter → a high-pressure pump → first reverse osmosis membrane group
→ alkali device → secondary high-pressure pump → secondary reverse osmosis membrane group
→ secondary high-pressure pump → secondary reverse osmosis membrane group
→ intermediate water tank → intermediate pump → secondary high-pressure pump → secondary reverse osmosis membrane group
→ intermediate water tank → intermediate water pump → intermediate water tank → intermediate water pump Intermediate water tank → intermediate water pump →
Ultraviolet germicidal lamp → TOC ultraviolet lamp → deoxidation membrane group → EDI device → primary polishing mixed bed
→ Ultrapure water tank → ultrapure water pump → plate heat exchanger → secondary TOC ultraviolet lamp → secondary deoxygenation membrane group
→ booster pump → secondary polishing mixed bed → terminal filters → ultrapure water point of use.
2, bottled mineral water equipment process system description
The system is divided into three parts, namely, raw water pretreatment, ultrapure water preparation, ultrapure water recycling. Each part of the function is briefly described as follows:
3, pretreatment
The main purpose of pretreatment is to remove suspended solids, colloids, hardness, organic matter and residual chlorine in the raw water to prevent subsequent reverse osmosis operation of impurities. Treatment facilities include raw water tank, raw water pump, backwash pump, plate heat exchanger, double media filter, activated carbon filter, flocculant dosing system.
