The A-Series proprietary thin-film reverse osmosis membrane elements are characterized by high flux and high sodium chloride rejection. AK HR low pressure brackish elements are selected when high rejection and low operating pressures are desired. These elements allow significant energy savings since good rejection is achieved at operating pressures as low as 100 psig (689 kPa).

These elements are recommended for low brackish water with salt concentration (TDS) levels up to 5,000mg/l. In turn, AK HR elements produce a permeate quality close to a standard brackish membrane element at a much lower pressure. Specifications

SUEZ membranes

SUEZ spiral wound membrane elements purify water for drinking water, boiler feedwater, seawater desalination, rinse water, and water reuse.

These highly efficient membranes produce high-quality product water from virtually any source including surface water, tap water, well water or seawater.

Benefits and Features

•     reduce salinity and chemical oxygen demand (COD)
•     remove chemical contaminants
•     recover acid streams.
•     clean-up hot condensates
•     pre-concentrate streams prior to evaporator
•     reduce energy requirements
•     reduce wastewater volumes by increasing water reuse
•     lower operating costs
•     reduced equipment downtime

GE custom designs membrane elements to operate effectively in challenging environments,

including extreme pHs, temperatures from 40° to 180° Fahrenheit (5° to 80° Celsius), oil contaminated streams and highly viscous solutions.
