Ideally with the waste line filters being bigger than the previous. I have a 400 GPD after my 100 GPD on the waste path. Comes out 70 ppm when mixed with the filtered line, through a di filter to 0-2 ppm
Close but no, incoming ~600ppm. Out around 30 as-is on one membrane. DI required.
I am chaining the RO membranes on the waste path to reduce waste, I recombine. Without the 400 GPD after the 100 GPD I was getting double the PPMs on the out line and burning through my DI media really quickly
Run brackish membranes in the secondary, then run the secondary permeate back in to the primary. Done correctly you can achieve 90% permeate to 10% concentrate. Dow actually has worksheets to do the design, on ours we run recirc to achieve correct flow rates per membrane.
Be mindful of the constituents of the concentrate, a lot of time it becomes hazardous waste running at low waste.
Those civil penalties follow you forever though, when you try and renew your license it wont let you. If you file taxes they’ll garnish you, id personally take statue of limitations over civil fines. Been there did that wasn’t fun
A lot of times the Civil fines aren’t even being imposed. I know a lot of people that got raided in Anza, no one really got screwed with unless they were stealing utilities. People hear that and assume low risk.
Ya it can go Eitherway i guess, if they lay those epa fines on you probably gonna feel that. I think there just doing to take peoples land here. They started raiding whole sections not just big spots, if i was the county and wanted to sell foreclosed land to someone id want it to be somewhat close together rather than all spread out. Every situation is different, saw my friend loose his land be had for 15 yrs and have seen the exact opposite. I just know my experience with civil fines
