Potable Water Treatment

Clean, great-tasting water is vital—and with surface water becoming increasingly affected by environmental factors, treatment plants must adapt fast. Nordic Water’s advanced technologies deliver reliable performance across filtration, sedimentation, sludge treatment, and more. Their DynaSand Filter enables compact, space-saving systems with consistently high-quality results—even as raw water conditions change.

Industrial Water Treatment

Water is vital to industrial processes—from cooling and cleaning to production itself. Circuit Water provides tailored treatment solutions for industries like brewing, dairy, steelworks, and paper, helping clients manage raw, process, and wastewater efficiently. In the mining sector, where wastewater can contain complex slurries and contaminants like arsenic or fine slimes, Circuit Water’s specialized equipment ensures reliable, high-performance treatment—even in the most demanding conditions.

Lake Restoration

Every lake has a natural limit to the pollution it can handle. Urban runoff and nutrient overload often push lakes into unhealthy, oxygen-deprived states. Circuit Water’s AIRE-O2 Aerators provide proven in-lake restoration by boosting dissolved oxygen and promoting natural circulation. This sub-surface aeration helps reverse eutrophication, supporting healthier ecosystems and restoring lakes to a balanced, aerobic state.

Oxidation Pond

Artificial circulation and sub-surface aeration are powerful tools for improving water quality in shallow lakes and ponds. By mixing the water and boosting oxygen levels, these systems prevent stratification, reduce harmful algae like cyanobacteria, and lower internal phosphorus loading. Circuit Water’s advanced aeration solutions create a healthier, more balanced aquatic environment—naturally and efficiently.

Mining

Mining and quarrying operations produce vast volumes of wastewater—often contaminated with fine particles, heavy metals, oils, and chemicals. From rainfall runoff to complex slimes in gold and coal extraction, these water streams are difficult to treat. Circuit Water delivers specialized treatment systems designed to handle the most demanding mine wastewater, ensuring effective separation, contaminant removal, and compliance with environmental standards.

Municipal water and waste water

With only 2.5% of Earth’s water being fresh, desalination is no longer optional—it’s essential. Circuit Water leads the way in advanced desalination solutions, from robust pre-treatment systems and ultra-efficient ultrafiltration to high-performance Reverse Osmosis skids. Whether treating brackish water or seawater, our compact to large-scale plants deliver safe, potable water with low maintenance and optimal energy efficiency—producing up to 50 million litres per day.
