Neutralization systems are used to take the pH value of the wastewater to 6-9, before it is released to the receiving environment. Liquid waste from laboratories serving in different sectors, especially hospital laboratories, cannot be sent directly to sewage.

Therefore, such waste waters must be subjected to a pre-treatment phase of neutralization and disinfection. Thus, the liquids with acidic or alkaline properties have been balanced in terms of pH; the generation of pathogenic organisms such as bacteria, virus etc. that it will contain will be prevented.

The tests performed in hospitals' laboratories are carried out with fully automated devices called auto analyzer. Liquid wastes from these devices are considered medical liquid wastes and are included in the hazardous waste class.

Some of the medical liquid wastes are;

  • Samples such as blood, serum and urine,
  • Chemical substances (reagents) used in the analysis for identification and diagnosis,
  • Cleaning solutions (detergents with acidic and alkaline characteristics),
  • The lavation generated as a result of laundering process implemented by deionized water and cleaning solutions at the end of each analysis by auto analyzers,
  • All kinds of surgical instruments and equipment used in the operating rooms have lavation containing detergent, body fluids and blood which is used for physical cleaning before sterilization.

In terms of a solution, considering the characteristic of medical liquid waste, it seems appropriate to discharge it into the sewer system after neutralization and disinfection.

Tes Water Group, with its strong R & D and innovation efforts, has developed TN Series Neutralization Systems which neutralize and disinfect all the liquids generated in the laboratories quickly and safely in an automated way.
