water treatment

Purified water

Q1：Raw water pretreatment process.

A：Mechanical filtration, activated carbon, softener.

Q2：The role of the plate heat exchanger.

A：Plate heat exchangers are used for sterilization of pretreatment systems.

Q3：What is the conductivity of primary reverse osmosis effluent and secondary reverse osmosis effluent?

A：Usually the conductivity of primary reverse osmosis effluent is lower than 10, and the conductivity of secondary reverse osmosis effluent is lower than 4.

Q4：RO1500L/H, is this the input amount of sewage?

A：Usually the output is written, not the input.

Q5：Is water pretreatment required before both primary and secondary reverse osmosis?

A：Yes, water pretreatment is required before both primary reverse osmosis and secondary reverse osmosis.

Q6：The difference between the semi-automatic control system and the fully automatic control system of the water treatment system.

A：The fully automatic control system has high performance, it can be controlled directly on the touch screen, and various indicators can be directly observed.

The semi-automatic control system is that the operator manually controls the valve.

1. Fully automatic startup:

(1). Before operation, it is necessary to ensure that the preparations for reverse osmosis have been completed, and the valves of the pretreatment system are in operation.

(2).Primary reverse osmosis: open the primary pressure regulating valve 450, open the fresh water valve and the concentrated water valve, turn on the power switch, set the booster pump, primary high pressure pump and dosing pump switch to automatic, and press the operation mode button Set to Auto and the unit starts automatically. Adjust the primary pressure regulating valve and concentrated water valve to make the flow rate reach the rated value.

(3). Secondary reverse osmosis: open the secondary pressure regulating valve at 450 degrees, open the fresh water valve and the concentrated water valve, turn on the power switch, set the secondary high pressure pump switch and the operation mode button to automatic, and the device will start automatically. Adjust the secondary pressure regulating valve and concentrated water valve to make the flow rate reach the rated value.

2. Manual boot:

(1).Primary reverse osmosis: open the primary pressure regulating valve at 450 degrees, open the fresh water valve and the concentrated water valve, turn on the power switch, and set the booster pump, primary high pressure pump, dosing pump switch and operation mode button to manual, The device starts automatically. Adjust the primary pressure regulating valve and concentrate valve to make the flow rate reach the rated value.

(2). Secondary reverse osmosis: open the secondary pressure regulating valve 450, open the fresh water valve and the concentrated water valve, turn on the power switch, set the secondary high pressure pump switch and the operation mode button to manual, and the device will start automatically. Adjust the secondary pressure regulating valve and concentrated water valve to make the flow rate reach the rated value.

3. Shutdown:

(1). The switches of operation mode, booster pump, primary high pressure pump, secondary high pressure pump and dosing pump point to stop, and the switch of power supply points to close.

(2). When the pretreatment control is manual, close the tap water inlet valve in front of the original water bucket.

(3). When the pretreatment control is automatic control, it is better to close the raw water inlet valve before the primary pump.

(4). If the pretreatment control is automatic control, the host power needs to be powered on for 24 hours, but the power switch on the panel can be turned off.

Q7：What is the maximum size of water treatment equipment?

A：80 tons.

Q8：The process of primary water treatment. (Take the processing capacity of 500L per hour as an example)

A：Raw water - pass the flocculant through raw water tank - sand filter - carbon filter - water softener - security filter - primary reverse osmosis.

Q9：The process of secondary water treatment.

A：Raw water - pass the flocculant through raw water tank - sand filter - carbon filter - water softener - security filter - primary reverse osmosis - secondary reverse osmosis - EDI - precision filtration - pure water tank - precision filtration - ultraviolet - feed pump.

Q10：The role of Y-type filter in water treatment.

A：Y-type filters can prevent backflow and filter particles, and are generally used for industrial steam filtration and coarse filtration of water.

Q11：When making shampoo and shower gel, what level of water treatment is recommended?

A：Usually a primary reverse osmosis treatment is sufficient.

Q12：The difference between reverse osmosis and water treatment.

A：Reverse osmosis is a part of water treatment.

Distilled water

Q1：What is the storage temperature?

A：The storage temperature should be above 80°C or below 4°C.

Pure steam

Q1：How many degrees of water can be used for injection?

A：The water can only be used for injection when it reaches 85°C.

Distribution system

Q1：What are the components of the distribution system?

A：Storage tanks, pumps, UV, heat exchangers.
