Installation of ultra-pure water equipment for polysilicon

2016-05-17View Original

Thread Content

  The ultra-pure water equipment used for polysilicon employs the world’s most advanced EDI continuous electro-deionization technology. Due to the high requirements for the quality of the water entering the system, a highly specialized pre-treatment system is in place, which includes multi-media filters, water softening equipment, precision filters, and reverse osmosis systems. High-standard ultrapure water can only be obtained through high-standard pretreatment of water.   Process Flow of Ultra-Pure Water Equipment for Polysilicon 【Laitread Hangzhou Water Treatment Equipment Company www.hangzhoushui.com】
1. The traditional water treatment method for producing ultra-pure water for the electronics industry uses ion exchange resins; the basic process flow is as follows:
Raw water → Multi-media filter → Activated carbon filter → Precision filter → Intermediate water tank → Cation exchange resin bed → Anion exchange resin bed → Mixed exchange resin bed → Ultra-pure water tank → Ultra-pure water pump → Post-filter → Point of use

2. Another method involves combining reverse osmosis water treatment equipment with ion exchange equipment to produce ultra-pure water for the electronics industry; the basic process flow is as follows:
Raw water → Multi-media filter → Activated carbon filter → Precision filter → Intermediate water tank → Reverse osmosis equipment → Mixed exchange resin bed → Ultra-pure water tank → Ultra-pure water pump → Post-filter → Point of use

3. A yet further approach involves using reverse osmosis equipment in combination with electro-deionization (EDI) equipment to produce ultra-pure water for the electronics industry. This is the latest technology for generating ultra-pure water, and it is also an environmentally friendly, cost-effective method with great potential for development. The basic process flow is as follows:
Raw water → Multi-media filter → Activated carbon filter → Precision filter → Intermediate water tank → Reverse osmosis equipment → Electro-deionization (EDI) → Ultra-pure water tank → Ultra-pure water pump → Post-filter → Point of use

Installation of Ultra-Pure Water Equipment for Polysilicon
1. Remove all the components of the ultra-pure water equipment from their packaging, organize them accordingly, and label them properly.   2. First, connect the pipelines: ensure that the inlet, outlet, concentrated liquid, and exhaust pipelines are properly connected without any leaks.   3. Then proceed with the circuit wiring, making sure to distinguish between the positive and negative terminals, and ensuring that the ground wire within the module is properly connected to ground.   4. Connect the control circuits for the water pump motor, level, pressure, etc., according to the circuit diagram provided by the manufacturer, and verify that everything is correct.   5. Sharpen the rebar and drive it into the ground to a depth of more than 1 meter, then firmly connect the grounding wire to it.   I hope we can learn from each other, discuss together, and make progress as a group.
