DIY Electrostatic Precipitator With Liquid Electrode Test Chamber 

Hi Chris, Thanks for the tips! I definitely need to explore this again as it has been a long time since experimenting with high voltage. I haven't tried switching polarity on this particular setup but have on the ESP style builds I made and did notice a difference. All the best to you :)

Hi Dustin, glad to have helped :) Hope your experiments go smoothly. A good tip is to use a PVC pipe with some tin foil taped on the end to act as a shorting rod used to de-energize the high voltage capacitors.

i dont mean to be so offtopic but does someone know of a trick to get back into an Instagram account..? I was dumb lost the password. I would appreciate any assistance you can give me.

@Terrance Jeffrey instablaster =)

@Stephen Antonio i really appreciate your reply. I found the site thru google and I'm trying it out atm. I see it takes a while so I will get back to you later with my results.

@Stephen Antonio it worked and I actually got access to my account again. I'm so happy:D Thanks so much you really help me out :D

Thanks NOBOX! Love your channel by the way :)

It can be done using a static electricity generator that produces a much lower current which is much less likely to kill someone than using a microwave oven transformer but that is still high voltage. The high voltage is necessary to establish a strong enough electric field to attract particals as well as corona/ionization to charge the particles. The only low voltage means would involve mechanical filtration and heat based filtration techniques.

Hello, here is the schematic I used locketech.weebly.com/uploads/5/0/1/5/5015829/overallelectrical_schematics.png Also the components are simply high voltage diodes and capacitors that are rated above 2Kv. I found them on ebay. The higher the value of capacitance, the better energy transfer. One voltage multiplier uses 10 capacitors and 10 diodes.

Exact values are 2200pF 3.1kv capacitors and 250mA 4kv diodes

Thank you, dear friend.

@@LockeLaboratory the schematisc not found bro, can u repair the link

@@ervanfahrizal2071 Oh thanks for letting me know. I fixed it. It is also here: lockelab.weebly.com/uploads/5/0/1/5/5015829/overallelectrical_schematics.png

You could do that, it may limit your output current and efficiency would be lower because you have a lot more capacitor/diode stages. Each stage will have some losses due to resistance and corona losses. A transformer simply allows one to jump to a much higher voltage in one stage.

if I may ask again , what specs MOT you use, and the capacitor you use , where can I buy it because , in my country is very difficult to find it, I am interested in your project , for my final project

Thank's for your respons

I'm using baking soda in the water so it should be safe.

Vahagn melikyan i used a cockroft walton multiplier circuit which rectifies AC into DC

+jlocke8 so i just series the cap, it save just put it in series ? or put some another passive component to secure the series capacitor, can you help me with this problem ?

+jlocke8 in some forum i see their use resistor to remove make leakage current from the capacitor, or i just tripled the capacitor in seriest without the resistors beacuse in my country it so hard to get high power resistor to secure the leakage current

+jlocke8 have you already, measure the output voltage of this circuit ?

+jlocke8 thank you for youre respons

its the corona that will produce the ozone. From there it is the voltage level how the terminals are designed to produce the amount of corona and the amount of oxygen present to be converted to ozone. I believe the polarity of the voltage has an affect with positive voltage producing less than negative.

​@@LockeLaboratory I'm intrigued by this type of air filter and intend to build one to remove solder fumes, but the ozone worries me more than the fumes. When you have worked with this, have you ever felt a certain smell around the apparatus? (It's a very distinct smell)

@@LockeLaboratory Also, can the corona discharge be tuned in order to produce less ozone without making the filter less effective? And kudos for being active 8 years after you published the video 👌

@@minime9400 thanks! Yes ozone is a real concern which may negate the practicality of this device for home use. There are some moves to minimize effect of ozone but it will never be zero since corona is also required to ionize incoming gas. In general what increases ESP's filtering power can increase ozone generation rate unless you do something expensive or exotic such as using an oxygenless environment or perhaps converting to electrospray to turn the ESP to a wetscrubber. There are optimal parameters for ESPs and I'm sure there are research papers written on it. In general sharp protrusions increase corona production. Typical design is a wire within a cylindrical tube or wire sandwiched between plates. On the wires are the series of barb protrusions to concentrate the electric field where corona is produced. Yes stopped making new videos since not much time anymore. Hope to find the time again to make more videos while juggling a busy life.

see step 35 of this link. It is the schematic that I used. hackaday.io/project/7237/instructions?page=4
