05.01.24 -- Ceramic Membranes Offer High Performance, Long Life, And Lower Operating Costs For Water Treatment

Microfiltration and ultrafiltration have become mainstays in the water treatment arena. These processes remove contaminants from water by passing it through a low-pressure membrane. Membrane filters are constructed with a variety of materials with various pore sizes. The challenge is determining which best suits the application with regard to performance, cost, and ease of operation.

Anion exchange treatment technologies produce a brine/contaminant discharge, while reverse osmosis solutions generate a concentrated arsenic reject. By comparison, the only cost of a properly designed iron-based adsorption system is periodic media changeout.

PFAS, or per- and polyfluoroalkyl substances, are quickly emerging into a major environmental and human health concern. Characterized by their extreme resistance to breaking down — owing to the molecules’ carbon-fluorine bonds, the strongest in organic chemistry — PFAS are persistent in the environment and can be found in water, wastewater, soils, air, food, and in the blood of humans and animals.

In this case study, read how the Lunenburg Water District improved their water disinfection system with the installation of an Atlantium RZ300-11 HOD UV system. The system effectively disinfects water, meets future demands, and eliminates chlorine taste and odor.
