washing maschine -lots of particle system parts

hellow.
I’m working on a short video for my companys commersial use.

i have this maschine cleaning the cart.
with watter spraying nozzles. Theres 30 nozzles. each has about 5-7 particles systems animating watter, some have even 15 system because the angle off water spraying is wide.
each particle system has 10.000 emision parts. So thats aloooth of emision parts in total. Rendering video seems impossible to me.
Can anyone look up my .blend file render settings. what could i do diffirent to reduce render time and still get almost the same quality video?

One problem i have with particle system is that where the life time of the emission is longer you can see that watter spray is curving on the top nozzles. how could i change that?

Also i had problem with adjusting all the nozzles lifetime as the washing system spins around and changes the lenght from nozzle to cart. So i decided to animate video of inside seperatly than outside.

the final video would be about 1 minute long and that or better quality
