This involves adding muriatic acid (in the conex) to one of our waste water totes and mixing with a pump until the pH of the water in the tote is neutral ~pH of 7 approximately. Steps: 1) Hook pump and hose up to waste water tote to recirculate from bottom port to the top lid. 2) Add muriatic acid through top lid. Start with 1/2 gallon. 3) Turn on pump and recirculate for 45 minutes (can be started before doing wash tasks). 4) Check the pH on a sample of the water. 5) Repeat as necessary with 1 cup at a time, mixing for 30 minutes. 6) Note the steps you've gone through in the log book. -------------------------------------------------------------- Zac Imboden [email protected] 6355 North Burrage Ave Portland, OR 97217 971-563-2477 --Apple-Mail-4-846149253 Content-Transfer-Encoding: quoted-printable Content-Type: text/html; charset=US-ASCII <HTML><BODY style=3D"word-wrap: break-word; -khtml-nbsp-mode: space; = -khtml-line-break: after-white-space; ">One of the tasks needing to be = done is neutralizing waste water.<DIV>This involves adding muriatic acid = (in the conex) to one of our waste water totes and mixing with a pump = until the pH of the water in the tote is neutral ~pH of 7 = approximately.</DIV><DIV><BR = class=3D"khtml-block-placeholder"></DIV><DIV>Steps:</DIV><DIV><BR = class=3D"khtml-block-placeholder"></DIV><DIV>1) Hook pump and hose up to = waste water tote to recirculate from bottom port to the top = lid.</DIV><DIV>2) Add muriatic acid through top lid.
