Nanofiltration membranes review: Recent advances and

Jan 15, 2015 · Nanofiltration (NF) membranes have come a long way since it was first recognized in the late 80's. With properties in between ultrafiltration (UF) and reverse osmosis (RO), NF membranes possess pore size typically of 1 nm which corresponds to molecular weight cut-off (MWCO) of 300500 Da. NF membranes in contact with aqueous solution are also slightly charged due to the dissociation

Dissolved oxygen is the main source of corrosion in boilers. The concentration of oxygen in boiler waters should be below 0.05 ppm for low pressure boilers and less than 0.01 ppm for high pressure boilers (~ 500 psi). Oxygen enters the boilers through raw make up water and also through infiltration of air into the condensate system.

Ammonia - Wikipedia

Ammonia is a compound of nitrogen and hydrogen with the formula NH 3.A stable binary hydride, and the simplest pnictogen hydride, ammonia is a colourless gas with a distinct characteristic of a pungent smell. It is a common nitrogenous waste, particularly among aquatic organisms, and it contributes significantly to the nutritional needs of terrestrial organisms by serving as a precursor to
