Chemical Dosing Systems , pac feeding system
Specifications:
Chemical dosing system has many different combination types according to different requirements from system, such as volume and quantity of solution tanks, quantity of metering pumps etc. The types can be one tank one pump, one tank two pumps, two tanks and three pumps, two tanks and four pumps etc.
Pipe material:pvc,304ss,316ss
Description:
Chemical dosing system mainly consists of solution tanks, mixers, metering pumps,
liquid level meters, electrical control cabinet, piping, valves, distributors, safety
valves, voltage stabilizers, pressure gages, check valves and frame etc.
The parts are all installed on a frame to be a separate chemical doing unit compactly and reasonably, thus greatly reducing the chemical design and field installation workload and reducing the covering area.
Solution tank is equipped with magnetic level meters which can display locally or remotely, and has high-level alarm, low-level alarm and low-low level pump stop protection function.
According to the requirements from user, manual local chemical dosing or automatic chemical dosing can be realized. The electronic components and instruments are assembled in an electric control cabinet which has the advantages of compact structure, safe and convenient for commissioning and operation.
This includes automation controls which can communicate with a 4-20mA signal coming from a computer. Capacity is adjusted with VFD.
Main components:
1. automatic intelligent control system
2. diaphragm metering pumps
3. dosing bucket
4. fouling resistance on-line monitor (optional)
5. water quality parameters on-line monitor (optional)
6. Conductivity on-line control device (optional)
7. PH value on-line monitor (optional)
8. Chemical concentration monitor (optional)
9. Corrosion on-line monitor
10. Electromagnetic pollution discharge valve (optional)
11. Pulse flow meter (optional)
Applications:
- Pumping Sodium hypochlorite for disinfection and caustic and cyanide removal
- Lime slurries for pH control (corrosion control) and coagulation
- Ferric chloride and alum injection for coagulation
- Copper sulfate injection for algae control
- Pumping of activated carbon or diatomaceous earth slurries for odor and color control
- Pumping of caustic soda (NaOH) for metal removal, pH control, and cyanide removal
- Anionic and cationic polymer injection for phosphate removal, coagulation and filtration
