Pretreatment system
    The purpose of raw water pretreatment is to remove suspended solids, colloids, organic matter (microorganisms) in the water to meet the requirements of the subsequent treatment process. The use of advanced and economical reverse osmosis desalination device as the main desalination process, reverse osmosis membrane pretreatment of water has its specific requirements. Therefore, the pretreatment needs to be considered in conjunction with the water requirement of the selected reverse osmosis membrane. Specifically, reverse osmosis pretreatment is done in order to:
     · Prevent membrane surface contamination, that is, to prevent suspended impurities, colloids, organic matter (microorganisms), etc. attached to the membrane surface or fouling membrane components into the water flow channel.
     · Prevent film surface fouling. By adding a scale inhibitor to prevent the formation of insoluble salts.
     • Ensure that the membrane is protected from mechanical and chemical damage and that the membrane retains good physical and chemical conditions.
     · Preprocessing to achieve the following indicators:
       FTU <1
       SDL15 <2
       TOC <2PPM
       CODMn <1.5mg / l
       FE <0.1
       Free Cl <0.1
       PH 2-11

1. quartz sand filter
The system is equipped with FRP filter. The filter is filled with refined, with a good gradation of quartz sand, in the normal work, the treatment of water 54m3 / h.
Backwash to set the time parameter to control the backwash cycle, usually one to two days, depending on the original water turbidity may be.
In the case of
2. Activated carbon filter
Activated carbon filter for the adsorption of raw water in the organic matter and harmful substances, the system set glass fiber reinforced activated carbon. The filter is filled with fine fruit shell activated carbon, in the normal operation of the treatment capacity of 63m3 / h.
Rinse and backwash the time parameter set to control the cycle, when the cumulative run to the set time for the filter backwash, washing process, the activated carbon filter layer of impurities out, loose filter layer.
In the case of
3. Scale inhibitor system
Scale inhibitor system can delay the growth of salt crystals to delay the precipitation process, prompting the crystal does not form a certain size and enough time to settle down, can reduce the precipitation.
In the case of
The Importance and Objectives of Pretreatment of Reverse Osmosis System:
Reverse osmosis system, including raw water pretreatment, reverse osmosis device, post-processing three parts. Reverse osmosis of raw water pretreatment has its specific requirements. Due to the wide variety of raw water, its composition is also very complex, for the raw water quality and RO system recovery rate and other major process design parameters, select the appropriate pretreatment process system to reduce the RO membrane fouling, scaling, To prevent the RO membrane desalination rate, water production rate reduction, especially for the current deterioration of the water source, selected from a correct pretreatment system, will directly affect the function of the entire water treatment system. As we all know, RO system operation failed, most of the situation is due to incomplete processing system and the resulting function. In order to ensure the normal process of reverse osmosis, raw water must be pretreated.

4. 5μm security filter
      1) its role is to intercept the raw water is greater than 5μm particles into the reverse osmosis system. These particles may be punctured by a high-pressure pump to penetrate the reverse osmosis membrane module or scratch the impeller of the high-pressure pump, resulting in system leakage or performance degradation.
