Got this from wintecs is this correct splitting input waste and product ?

Yep, looks ok to me

They've set it up in parallel

I would also do the same as John Tomkins has suggested on the other thread running.

I would remove the restrictor and replace it with a control tap. If you spend some time experimenting with waste to pure ratios  and test the pure output, you will be able to find the sweat spot of your system.  You may be able to reduce your waste a little.

Every little helps being on a water meter.
