5, 000L/H RO Drinking Water Treatment Plant

1. RO Water treatment equipment includes pre-treatment, RO system etc. 

(1)Pre-treatment is included raw water tank, raw water pump, quartz sand filter, activated carbon filter and security filter. 
A. Quartz sand filter: A laminated filter is provided to prevent sand, flocculent and colloid entering into membrane element. Its basic filter element is formed by quartzes sand and anthracite. B. Active carbon filter: This is provided to absorb organic materials, residual chlorine and other injurants, thus it can reduce the effluent COD and keep SDI under and CL2 under 0.1 mg/L. C. Precision filter (micro filter): PP filter of 5um is installed to prevent fine particulate entering the high lift pump and RO membrane. 

(2)RO system is included that booster pump, membrane and membrane housing, electronic Control System. 
It cut out colloids, bacteria, virus and other impurities, and keep output water conductivity below 5um/cm. 

(3)Pure water tank: When the pure water tank is full, the RO machine will automatically come to stop, when the pure water tank is empty, the RO system will automatically run to produce the pure water. 

2. Working process: 
Raw water ->Raw water tank -> Raw water pump -> Quartz sand filter -> Active carbon filter-> High pressure pump ->Security filter -> RO equipment->Pure water tank 

3. Advantages: 
1). Can production water continuously and highly automatic 
2). No need the chemical regeneration, easy operation 
3). RO system choose the import USA DOW membrane 
4). Automatic switch on when low water level, and switch off when high water level 
5). RO membrane can backwash automatic and reduce thepollution. 
6). Water shortage protection for multi-stage pump 
7). Porduction water condutivity meter can test the monitoring quality on line contionuosly. 
8). Low operation Cost and Long life span 
9). It is PLC program controlled 
10). Easily control and Maintained. 
11). Auto membrane flushing 
12). Environmental protection, Low power consumption 
13) Auto flush/backwash 
14) Low /high pressure protection

Beam Expander

A beam expander is any optical system designed to increase the diameter of a Laser beam. In most cases, the term is taken to mean a telescope designed to take a small-diameter collimated beam input beam and produce a larger diameter collimated output beam, thus reducing the divergence of the beam. The beam expander consists of a negative input lens and a positive objective. The expansion factor is the ratio of the focal length of the two lenses.

Features	Applications
Low power loss Good output collimation Able to withstand laser power of more than 1000 W Adjustable divergence angle of 18 to 32 mrad with the variable beam expanders	Precision laser machining: capable to provide a high power density focal spot. Laser range finder: capable to provide a highly collimated beam. Combining with a spatial filter, able to modify laser power distribution.
