Silicon industrial waste water treatment

An efficient and environmentally friendly way of water treatment and re- extraction.

Silicon used to make semiconductor, produces waste water during the process of incision. PG ahpa Ca can be used to agglutinate in a very low cost.
Nevertheless, PG alpha has very high dehydration property, it is possible to re extract silicon.

Flow chart of water treatment

1. reservoir

   

   catch basin

   when the volume of wasted water reach a certain level, sensor will receive and pump this into dispensing level.

2. Primary treatment

   

   PAC dispensing

   Deal with the water flowing from catch basin with PAC. And then Agglutinate the suspending matter.

3. secondary treatment

   

   PG alpha 21 Ca addition device

   The effect of agglutination will increase by adding PG alpha 21 Ca. when the agglutination become bigger , separate the suspending matter from the waste water, the speed of separation will increase.

4. sedimentation

   

   Still pot

   Agglutination of treatment water sediments in the sedimentation sink. Coal could be recover from sedimentation , and we then give out treatment water.

1. Primary process tank

   

   microvesicle treatment adjustment trough

   when the treatment water is poured into babble of 10 um diameter, it will be absorbed by suspending matters, and is disparate when the babble floats. When the babble becomes smaller, free radical created by the babble will decomposes the organic substance.

2. fixed separation tank

   

   Sludge recycle devices

   The floating foul substance and treatment water will be separated by rotary collation devices. After the separation treatment water will be pumped into Agglutination devices.

3. Secondary process tank

   

   Agglutination reaction devices

   String with agglutination agent. Agglutinating suspending substance and left organic substance and forming them into agglutination substance.

4. sedimentation tank

   

   Still pot

   Separating and sedimenting and release treatment water.

Example of Water purification trough processing

Example of Water purification trough processing

Water trough 2000×6000×1500mm four troughs is one set

• water pump 280L/min 3 sets(for pumping water)
• Water pump 280L/min 1 set(for stirring)

Put the clapboard between NO3 and NO4 tank to make the water flow up and down. The clapboard is designed to keep the floating accumulating substance from flowing
