antiscalants in ro membrane scaling control

Antiscalants in RO membrane scaling control

Various antiscalants have been developed and applied in water treatment industries, such as boiler water, cooling water, thermal desalination and membrane industries, to mitigate scaling (Chaussemier et al., 2015; Darton, 2000; Hasson et al., 2011; Liu et al., 2019; Nowack, 2003). Specific knowledge regarding the performance of different

The Selection of Efficient Antiscalant for RO Facility

As was already discussed [ 5, 6, 7 ], proposed antiscalants with new unknown brands require evaluation of their efficiencies. but antiscalant testing results provided by different researchers often do not provide real conditions for crystal nucleation that exist in membrane industrial devices.

While reverse osmosis (RO) for desalination of brackish water, seawater and wastewater is a most economical and powerful method, its sensitivity to fouling points to the importance of understanding the water chemistry involved and methods of fouling control and system maintenance. As a chemical developer of antiscalants, antifoulants, and operation and maintenance chemicals needed for RO

scale inhibitor

Scale Inhibitor

Antiscalants ( scale inhibitors) are used in drinking water and process industry to prevent scaling or scale deposits on the membrane surface in a membrane-operated water treatment plant. Scaling occurs when the solubility limit of sparingly soluble salts/minerals is reached leading to the salt precipitation on the membrane surface as the

The feed water (Moscow tap water) was added to the feed water tank 1. From tank 1 the feed water was delivered by the pump 2 to membrane module 3. Spiral wound elements of 1812 standard (model 1812 R 100) tailored with low pressure RO BLN membrane were used. Membrane surface in 1812 module was 0.5 square meter.
