Four, pure water system unit composition and operation

1 Pre-processing system

Including multi-media filter (quartz sand, coconut shell activated carbon composition) PP cotton core fine filter.

1.1, multi-media filter

1.11 Suspended substances in water are smaller particles. Visible to the naked eye, these particles are mainly composed of sediment, clay, protoorganisms, and algae

Classes, bacteria, and polymer organic compounds are often suspended in water. When tap water passes through quartz sand it can remove large amounts of water

Activated carbon in suspended particles can remove the fishy odor from the reproduction and decay of aquatic organisms, plants or microorganisms in the water

An earthy odor or astringent taste given off by the decomposition of organic matter, the residual chlorine of disinfectant water. Ensure that the subsequent system is positive

Run normally. The reduction of residual chlorine in the water plays a great role in the protection of the softening resin and membrane components, and extends the reverse osmosis membrane

And the service life of the mixed bed. The packing material is granular fruit shell type activated carbon.

1.12 Flushing multi-media filter: (Flushing cycle: 1-2 times per week, depending on local water quality)

Flushing method: multi-media filter manual control to the positive flushing position, flushing 15 minutes after the dial to the positive flushing position, and then

Rinse for 10 minutes. After the rinse is complete, switch the multiway valve to the running state.

1.2, cation softener

In order to prevent the calcium and magnesium ions in the water from scaling on the reverse osmosis membrane, the membrane components were damaged by solid particles and large-scale scaling appeared.

The addition of softener before R.O reverse osmosis can extend the cleaning cycle of the system, so that the membrane life is extended and the cost is reduced. rinsing

Raw cation softener (cycle: depending on water quality), the method is as follows:

(a) First add 5 kg of industrial salt to the industrial salt VAT. Dissolve 15 kg of saturated solution with water.

(b) Backwash: Turn the manual multiway valve to the BACK WASH position (BACK WASH) for 15 minutes

Suction position (BRINE&SLOWR).

(c) salt water absorption: After the manual multiway valve is set to the salt absorption position (BRINE&SLOWR), the salt water is automatically absorbed (20 -

25 minutes).

(d) FAST RINSE: After absorbing 20 kg of industrial salt solution, turn the manual multiway valve to fast rinse.

Rinse for 30 minutes.

(e) Sampling test: Open sampling valve and take out sample water. Its requirements with a special softening water reagent test shall prevail.

Soften the water sample, drop the reagent, if the color of the sample water turns blue for acceptable, if purple or red for bad, to regenerate

For washing. After the cleaning is completed, the normal water supply (SERVICE) is carried out.

1.3, PP fine filter

The security filter is the last filtration device before entering the R.O reverse osmosis main engine, which must ensure that the tap water is entering the reverse osmosis

The pollution index SDI before the main engine is stable below 4. Because the pure water recovery rate of the reverse osmosis device is generally only 50%-60%.

The design water yield is 1t/h.

Operating principle:

(a) The PP cotton filter adopts a PP cotton filter with a pore size of 5um, and water seeps into the PP cotton from the outside through the micropores from the inner wall of the PP cotton

The heart tube penetrates out to filter out tiny particles of impurities larger than the aperture.

(b) After PP cotton is used for a period of time, more and more impurity particles are trapped outside the outer hole until it fails. Be sure at this time

Replace the filter element, otherwise it will pollute the subsequent reverse osmosis equipment, the general replacement cycle is 1-2 months (according to the local

Depends on water quality and usage).

1.4 Precautions:

(a) After the use of the precision filter element, the impurities trapped in the microhole will become larger and larger until they fail. Please focus on this time

Enable replacement. Generally, it is replaced once a month, and the frequency of replacement depends on the quality of raw water and the use time of the equipment

The filter element can be checked regularly every week whether it is completely contaminated and needs to be replaced, and the appropriate change can be determined after several repetitions

Change the cycle and keep going.

(b) Check the SDI value of the outlet water of the security filter regularly every day. If the SDI value is greater than 4, please check the inner filter of the precision filter

Whether the core seal ring is damaged or loose, if the filter element is contaminated, please replace the filter element in time.

2 RO Reverse osmosis system

2.1 Introduction

RO reverse osmosis unit is the heart of the whole pure water system, please users should pay special attention to maintenance, usually in the RO system

At the time of rotation, the acquisition of various operating data should be appropriately adjusted with the design reference values of the system. Adjust the water to the membrane

The quantity and working pressure are the main indicators, and the adjustment is made according to the blockage and pollution of the membrane. And the inlet pressure, the outlet

Water pressure, inlet flow rate, outlet flow rate, pure water conductivity, etc. should be recorded normally in order to find out the cause of system failure.

In general, the removal rate of organic matter in RO pure water system can reach 99.9%. For inorganic salts, it can reach 94%~

About 98%. Because the RO system has a fine ability to efficiently deionize, the resistance value of the water can be determined by both the water inlet of the system

Compared with the resistance value of the water outlet, the working efficiency is obtained. The ability of RO systems to remove minerals and organics due to weeks

Periodic washing, medicine washing operation, so it can maintain stable water quality.

Local operation data is designed on the basis of several factors:

1) Water inlet temperature is maintained within the design range (about 25 'C at room temperature)

2) The indicators in the water must be the same as the quality of municipal tap water

3) The water should be treated by pre-treatment equipment to reduce SDI and remove residual chlorine

The RO system adopts automatic control technology, and has the necessary protection, such as water shortage, full water, low pressure protection, etc

Does not mean that the system can be unattended operation for a long time, please regularly record the pressure, flow, temperature, conductivity parameters, when
