Acid Neutralization
Acids are hazardous to living creatures as well as organic and inorganic materials. Acids are corrosive and can burn tissue, break down organic material, upset aquatic environments, and dissolve metals. It can be difficult to use water in an industrial environment without disrupting the pH balance resulting in a waste stream that is potential hazardous to the environment. The most commonly controlled parameter in industrial wastewater is pH which is the measure of free acidity or alkalinity of an aqueous stream.
An acid, in simple terms, is defined as an excess of free H+ ions in solution. Simple acid neutralization reactions involve providing a hydroxide ion for each H+ ion as seen in the neutralization reaction below where hydrochloric acid (HCl) is neutralized using a base such as sodium hydroxide (NaOH). The result is simple table salt and water.
HCl + NaOH → NaCl + H2O
Acid Neutralization Systems
Digital Analysis manufactures a complete line of Acid Neutralization Systems for the neutralization of acids and bases from any industrial wastewater source. All of our acid waste neutralization systems are bi-directional and will neutralize acids and bases (alkalis) from any industrial source. Standard pH neutralization designs are available for flows up to 1,000 GPM and custom designs for flows in excess of 1,000 GPM.
We offer both batch pH neutralization and continuous pH neutralization systems depending on the application requirements. We manufacture four families of pH adjustment systems as follows:
pHASE pH Adjustment systems are batch acid neutralization systems designed to handle continuous flows (despite batch processing). The pHASE family is a very compact platform designed to fit into small spaces. pH systems in this family range in size from 1GPM to 40GPM. These pH systems are capable of handling concentrated acid and alkaline waste streams.
batchTREAT pH adjustment systems are very similar to the pHASE family of pH neutralization systems, however, these are much larger pH systems covering a range of 40GPM to over 1,000GPM. This family of pH neutralization system, due to its larger platform, is available with far more options.
labTREAT pH Adjustment systems are specifically designed to neutralize the wastewater streams from the pharma / biotech industry and employ features that allow for very efficient neutralization of CIP wastes. The labTREAT family of pH neutralization systems is capable of handling high flow rates in a small footprint. These pH systems are available in one, two, and three stage continuous flow through designs.
hydroTREAT pH neutralization systems are specifically designed for the masonry / concrete / tunneling industries. These pH systems can be used on construction sites to handle runoff water from hydro-demolition, concrete, or tunneling operations. The use of concentrated / hazardous acids such as sulfuric acid is not required. These systems utilize carbon dioxide (CO2) and are very effective for alkaline wastewaters.
