Application Guideline


PRO-pHx Technical Data

On going maintenance is required for the PRO-pHx chemistry to extend
indefinitely the productive life of treated acid baths indefinitely.
Maintenance includes:
    1) PRO-pHx treatment
    2) Effective filtration
    3) Analyze the acid and spike to maintain strength, at least weekly

  1. Treatment: Add PRO-pHx at 1% to the total acid/water bath volume for initial makeup.
    To maintain, add new acid at least weekly and 1% PRO-pHx based on the added acid volume only
  2. Filtration: Filtration is required. Ideal bath turnover rates vary from 1/2 to 4 turnovers per hour. Filtration can be effective at slower turnover rates. Find the ideal filter micron size for your needs. The most often-used filtration sizes are 5, 20 and 50 microns. However, filtration may vary from 1 micron to 100 microns. Effective filtration is necessary.
    • If the media clogs quickly during the production runs, filter with a larger micron.
      If the media does not clog during filtration, filter with a smaller micron.
    • Filtration micron sizes may vary from one bath to another. If numerous metals and large volumes of organics are being introduced into the acid during production, a larger micron size (30 - 50 - 75 micron) may be effective. If primarily metals and no organics are being introduced into the treated acid, then filtration may require 5 microns or smaller. Organics in the acid create a beneficial precoat on the filter media. Metal contaminants create more of a granular sludge on the filter media.
    • The filters will need to be cleaned or replaced anywhere from twice a day to once every three days, depending upon the volume of metals and organics introduced into the acid. Do not let filters just set in the acid and re-dissolve.
  3. Analyze: Analyze the acid and return the acid to the target strength at least weekly.
    PRO-pHx will not perform without regular acid spikes.
    Maintain PRO-pHx at a minimum of a 1% ratio ratio to the total acid volume added to the bath.
    Establish a maintenance program which provides at least weekly spikes of fresh acid and PRO-pHx, to continue to maintain the catalytic reaction.

PRO-pHx is not effective below a .75% ratio (By Volume) of the total acid bath.
These simple steps will allow acids to be maintained indefinitely with low levels of metals and organics.
