AI Technical Summary
Existing technologies for treating reverse osmosis concentrate suffer from high energy consumption, easy scaling, low recovery rate, and poor environmental performance, leading to environmental pollution and resource waste.
A reverse osmosis concentrate reduction and reuse system is adopted, including a concentrate reverse osmosis booster pump, an ultra-low pressure concentrate reverse osmosis unit, and a reuse water tank. The concentrate is treated with hydrochloric acid and scale inhibitor, and the ultra-low pressure concentrate reverse osmosis unit and chemical cleaning unit are used to achieve further concentration and desalination of the concentrate. The system is automated by combining DuPont Eco-Pro-400 low-pressure membrane elements and a PLC controller.
It achieves efficient, energy-saving, stable and reliable concentrated water recycling, reduces wastewater discharge, improves recovery and desalination rates, meets environmental protection requirements, and reduces operating costs.
