2.1. Quartz-sand filter

Description:

This system is equipped with quartz sand filter, and the filter is filled with refined quartz sand, which is used to intercept suspended matter, colloid and other impurities in the water. Backwashing time of the equipment is determined by inlet turbidity, which depends on raw water turbidity.

In reverse washing, compressed air is simultaneously fed into the water to scrub the filter material. The strength of the compressed air is 18-25 l/s · 2 m.

Technical parameter:

Model SYS-600
Capacity: 60 T/H
Working pressure: 0.25 Mpa
Material: SUS304
Filtering medium: High quality sand

2.2 Active carbon filter

Description:

Activated carbon adsorber is used to adsorb residual chlorine, odor and organic substances and other harmful substances in raw water, reduce the COD content, and prevent residual chlorine into RO device, to ensure the safe use of membrane elements in RO device. If the water contains only a certain amount of residual chlorine, and organic matter, odor or color content is very small, the activated carbon in the adsorber only regular replacement wear or reaction with the residual chlorine of carbon particles. If the organic matter in water, peculiar smell or chroma content are higher, need to replace activated carbon after using period of time commonly, specific change time should be decided by the organic matter in water, peculiar smell or chroma concentration.

Capacity: 60 T/H
Material: SUS304
Working pressure: 0.25 Mpa
Chaotic degree: Maximum 5 mg/l

2.3 Sodium ion exchanger

Description:

Because the source water contains calcium and magnesium ions, and the desalination rate of reverse osmosis is as high as 97%, the concentrated water side will produce calcium carbonate, magnesium carbonate, magnesium sulfate and other precipitates due to high concentration. The precipitation adheres to the reverse osmosis membrane surface, which will block the channel of the membrane element, causing the increase of pressure difference, the decrease of water flux and desalination rate, and affecting the normal operation and service life of reverse osmosis.

Technical parameters:

Model: SN2-60
Capacity: 60 T/H
Size: Ø2200*4000mm
Working pressure: 0.25 Mpa
Material: SUS 304
Filtering medium: 731 colophony

 

3. Precision filter

 

Description: 

The precision filter is installed in front of the reverse osmosis. The purpose is to prevent the abnormal operation of the front mechanical filter or activated carbon filter (such as the filter layer has not been formed after backwashing or other human factors), so as to prevent the water particles from entering the RO membrane module and damaging the RO membrane surface, the precision filter is needed to put in front of the RO.

The precision filter adopts polypropylene honeycomb filter element to improve the filtration precision. When the filter element differential pressure reaches 1.0 Kg/cm2, then it needs to be replaced.

Features:

  • the structure of precision (security) filter meets the requirement of quick replacement of filter element.
  • a discharge valve is installed on the water pipe that enters the precision (security) filter.
  • the operating velocity of the precision (security) filter shall not be greater than 10m3/m2.h(in terms of the surface area of the filter element).
  • precision of filter element filter of precision (security) filter is 5u and 1u.
  • precision (security) filter device body is stainless steel.
  • the top of precision (security) filter is equipped with exhaust valve.

 Technical parameters:

Model: FSJ-40-5
Capacity: 60 T/H
Working pressure: ≤0.3 Mpa
Quantity of filter pole: 30 pieces
Material: SUS 304
Filtering medium: Polypropylene membrane (PP MEMBRANE)
Size: Ø520*850 mm

 

4. Reverse Osmosis

 

Features:

  • Stainless steel main structure.
  • It has five membrane-shells, each membrane-shell contains three RO membranes.
  • RO membranes are supplied by Hydranautics.
  • Able to eliminate over 97% solute salt and over 99% colloids, microorganisms, microparticles and organics, etc.
  • The control system of the device adopts the combination of “site manual operation + automaticoperation by PLC” mode to complete various data collection andparameter setting in the operation room. If the PLC controller fails, it will not affect the normal operation of the treatment system. On-site manual operation mainly includes: operation of pretreatment filter, chemical cleaning of reverse osmosis unit, and etc.
  • Medium / activated carbon filter, installation of inlet and outlet water manual valve, backwash manual valve, positive wash backwashing drain valve, vent valve, pressure gauge, etc.
  • Manual valves are installed at the inlet and outlet of the security filter/precision filter. The replacement of the filler is determined according to the increase of the pressure difference of the filter. The service life of the filter element is generally greater than 3 months.
  • The high-pressure pump of the single-stage reverse osmosis unit is equipped with high and low pressure protection devices. When the inlet water pressure is lower than the set value or the outlet water pressure is higher than the set value, the high pressure pump automatically stops working, and the high pressure pump is also synchronized with the high and low liquid level control system of the front and rear water tanks.

RO system:

The single-stage reverse osmosis unit is equipped with a concentrate and fresh water flow-meter.

The working efficiency of the single-stage RO unit is controlled by adjusting the concentrate and fresh water valves.

The automatic quick-rinsing process of opening and stopping is set, and low-pressure rinsing is performed to remove the sediments on the side of concentrate water.

Equipped with online electric conductometer (Equipped on the RO water inlet pipe, RO water outlet pipe) to monitor water quality.

The RO membrane cleaning is manual cleaning. The RO cleaning agent will be determined after comprehensive analysis based on various types of information feedback.

All water tanks are equipped with liquid level transmitters, and the signals are introduced into the PLC control cabinet to control the liquid level and alarm.

On-site manual operation and automatic operation are independent from each other, do not interfere with each other. If automatic failure, can manually operate the water treatment system, and the liquid level control is running normally.

The main fault signal is introduced into the PLC controller, and the alarms are displayed on the touch screen, awaiting to be set right.

4.2. Membrane cleaning system

 Description:

After the water enters the reverse osmosis system, it is divided into two paths, one through the surface of the reverse osmosis membrane to get filtered, and the other moves along the surface of the reverse osmosis membrane and gradually get concentrated. In the concentrate water, containing a large amount of salt, organic matter, colloids, microorganisms and bacteria, viruses, etc. If the reverse osmosis system stops, these contaminants would immediately settle on the membrane’s surface, causing contamination of the membranes. Therefore, an automatic flushing system should be installed to clean the surface of the membrane while the machine stops.
