Enhancing Qatar’s wastewater management

Cannon Artes is constructing an advanced wastewater treatment and water reuse plant within one of the largest petrochemical complexes in the Middle East.

The facility, designed to support the water recovery requirements of a major polyolefin plant in Qatar, will process up to 25,000 cubic metres of effluent and cooling-tower-blow-down water daily. With a recovery capacity of 780 cubic metres per hour, the plant significantly reduces discharge rates, achieving nearly 80% water reuse.

This far exceeds regulatory standards. The facility is part of a nearly US$2bn project to establish a new polyethylene plant. The plant, designed with two polymerisation units and an annual capacity of nearly 2 million tons, incorporates advanced membrane technologies to manage industrial wastewater and cooling water blowdown.

Industrial effluents are treated using Cannon Artes’ proprietary EmbioArt Membrane BioReactor (MBR), while cooling water blowdown is processed with ultrafiltration (UF) and reverse osmosis (RO) technologies. The facility has a total treatment capacity of approximately 1,000 cubic metres per hour.

The project also includes a 600 cubic metre-per-hour remineralisation plant, equipped with six advanced calcite filters. This system increases pH and reduces the corrosivity of recovered water, setting a new benchmark for industrial remineralisation technology.

Sustainable operations

The Qatar project highlights Cannon Artes’ capability to execute large-scale, complex contracts. The company handled every aspect, from process design to procurement, manufacturing, assembly, testing, and delivery. All components were customised to meet client specifications, integrating cutting-edge technologies like EmbioArt MBR, UF, and RO for maximum efficiency and environmental sustainability.

Construction commenced in August 2024, with infrastructure expected to be completed within six months by early 2025. Full mechanical completion is slated for Q4 2025, demonstrating an impressive timeline given the project's complexity.

With projects delivered in more than 80 countries, the company has provided customised solutions to industries including oil and gas, chemicals, pharmaceuticals, textiles, and food and beverage, solidifying its reputation for excellence in industrial water management.

“Cannon Artes was chosen as the supplier of choice earlier this year, due to our proven ability to deliver large-scale and complex industrial wastewater treatment solutions that meet the highest environmental and efficiency standards,” said Alessio Liati, sales director at Cannon Artes. “To give an idea of the project’s scale, the water treatment plant alone spans an area comparable to three football fields, with more than 1,600 reverse osmosis membranes, 360 ultrafiltration modules, and over 17,000 sqm of active MBR membrane surface.”
