Equipment decisions for Pakistan projects.
For a textile ETP in Faisalabad, a tannery in Kasur, a housing STP in Lahore or a reuse project in Karachi, equipment selection starts with the wastewater and the required outlet quality. We discuss power supply, operator availability, chemical supply, spare parts and installation access alongside the process duty.
Based in Lahore, Aquenvia accepts project enquiries across Pakistan. Site visits, supply, installation and commissioning are scoped to each project.
