pH Neutralization

pH is a measurement of the acidity, neutrality or alkalinity of water; and plays a major role in environmental water disposal compliance.Sometimes, pH adjusting wastewater, without filtration, through a neutralization system meets city sewer discharge requirements.

However, many industrial wastewaters containing emulsified solids, oils, soaps, surfactants, or dissolved metals require pH adjustment in order to precipitate [drop] out of solution prior to filtration or dewatering.

The majority of ALAR wastewater treatment systems are pH driven; oftentimes requiring acid to lower the pH and break the emulsification, followed by caustic to raise the pH and precipitate the contaminants. In most cases, this simple pH adjustment is all the solids, oils and metals require to be captured by a 1-micron precoat filter such as the Auto-Vac®, Flex-O-Star® or Micro-Klean™.
