Industrial water · Barreiro, Portugal
Technical operation of industrial water systems
We design, build and operate WWTPs and water networks in industry — from intake to compliant discharge, with our own team and permanent assistance.
From the WWTP to the internal network: technical water management for industry
We work almost exclusively with industry. The scope is the facility's complete water system — not just end-of-pipe treatment.
Industrial effluents
Design, construction, modernisation and operation of WWTPs, sized to each industry's actual effluent.
Networks & utilities
Intake, distribution, cooling, heating, demineralisation and reverse osmosis — process water managed as a critical utility.
Water reuse
Closed internal cycles and alternative sources: less water drawn, less water discharged, lower cost per m³.
Compliant discharge
Discharge permits, national legislation and Best Available Techniques (BAT) — met in operation, not just on paper.
The water circuit in an industrial facility
We work at every station of the circuit. That is what makes it possible to close cycles, cut water and energy use and guarantee discharge.
Intake & polishing
Own source or public supply, treated to the quality the process demands.
Internal network
Distribution, pressure and protection of pipework and equipment against corrosion and scaling.
Process use
Raw material, transport, lubrication, cooling and heating — with Legionella under control.
Effluent & WWTP
Treatment sized to the actual effluent, operated with careful reagent dosing.
Reuse
Treated water returned to the process; rainwater and process water recovered.
Compliant discharge
Emission limit values met, continuously, with analytical records.
Solutions for effluents, networks, reuse and compliance
Seven areas of intervention, engaged individually or as global management of the facility's water. No generic catalogue: every proposal starts from a technical survey.
WWTP Management
Full management or periodic assistance, with specialised staff and 24/7 support, all year round.
Industrial Water Networks Management
From intake to reverse osmosis: the factory’s whole water network, run by a single team.
WWTP Construction & Modernisation
Projects tailored to each industry and effluent, with realistic investment and running costs.
WWTP Treatment & Cost Optimisation
Necessary doses, no overdosing: environmental compliance with controlled costs.
Compact Industrial WWTP Rental
A complete physico-chemical line in a 12-metre container — breakdowns, trials, seasonal effluents.
Water Balance in Industry
An audit of water consumption, waste and costs, with alternative sources identified.
Legionella Prevention & Control
Risk assessment and prevention plans under Portuguese law (DL 52/2018, Portaria 25/2021).

Barreiro's industrial heritage
QTA grew out of QUIMITÉCNICA AMBIENTE, of the CUF/QUIMIGAL group — the first company in Portugal to manage and treat industrial waste. In 2009 the water-treatment facilities business became autonomous; the accumulated know-how stayed.
We remain where Portuguese industry began: at the Barreiro Business Park, operating facilities across the country in partnership with major national companies.
