Savings through the reuse of greywater for industries

Industries today are seeking environmental initiatives that contribute to ESG indicators, particularly in terms of environmental actions, to enhance the market value of the company, promote socio-environmental awareness, and achieve savings through the reuse of renewable resources, such as through the treatment and reuse of greywater. 

The Greywater Treatment Plant (PRO ETAF) is an automatic and compact system with dual filtration designed for the treatment and reuse of greywater, reducing the consumption of potable water in non-potable activities and contributing to environmental awareness.

Greywater is wastewater generated from domestic processes such as faucets, showers, laundry, and sinks, which are separate from sewage (blackwater). Greywater can account for up to 80% of the sanitary effluent generated in a development.

Greywater, due to its lower concentration of organic matter compared to blackwater, often undergoes physical-chemical treatment processes in many applications. The aim is to reduce turbidity, odors, and perform disinfection of greywater for subsequent reuse.


Industries with green certification and environmental actions focused on ESG can acquire and implement a greywater treatment station, bringing about savings and environmental preservation through reduced water consumption.

Advantages of the Greywater Treatment System for industries

  • Automatic system, lower operational commitment;
  • Mobile and compact design;
  • Low-cost installation, maintenance, and operation;
  • Complies with environmental regulations;
  • Water treatment guarantee;
  • Technical and operational system training;
  • Optional final polishing with ozone;
  • Automatic or manual filter backwashing;
  • Modular treatment system;
  • Made of polypropylene, with UV protection, increasing the system's lifespan;
  • FRP filters longer lifespan without corrosion or rust;

We offer ease in the acquisition and implementation of water treatment systems, with options for purchase or lease contracts, along with a specialized team to perform technical, operational, and analytical monitoring of the water and effluent treatment plant.

Projeto Ambiental's line of water and effluent treatment products is manufactured in-house with customized designs, made from polypropylene (PP) structures with high thermal and mechanical resistance.

Consult Projeto Ambiental about the acquisition and implementation options for water and effluent treatment systems, including purchase or lease contracts.

The Greywater Treatment Process for Industries

The greywater treatment process involves the addition of chemical reagents to the water, including a sanitizer for disinfection and clarification of the water and a coagulant for solid agglomeration, along with dual filtration through activated carbon and quartz columns. There is also an option for final polishing with ozone injection, replacing the sanitizer, to enhance the final quality of the treated water.
