Some examples of industries that need to remove silica from the water before discharge or reuse are: cooling towers, boiler blow feed water or boiler blow down water, carwashes, semi-conductor manufacturers and steam injection oil recovery wastewater.

water treatment – precipating silica - Degremont®

This involves adsorbing silica over an Aℓ or Mg hydroxide floc. This co-precipitation can be carried out under hot or cold conditions. It is often carried out at the same time as CaCO 3 precipitation for carbonate removal.. silica removal using Mg 2+. When magnesium is present in well water and when its pH level is adequate, it will precipitate with some of the silica when carbonates are

Pentair - Silica-removal-package

The SRP can remove 99.8% of colloidal silica in a single process step, making it possible to meet the silica limits for high-pressure boilers and thereby maximize efficiency. The robustness of the X-Flow HFS60 membrane module allows for installation upstream of a reverse osmosis system or an ion exchange system.

Boiler Feed Water Treatment for Industrial Boilers and

Silicate and colloidal deposits decrease boiler efficiency and also result in premature failure of turbines. Ultrafiltration can remove greater than 99% of colloidal silica, as well as precipitated iron and aluminum. The reduction in particulate matter, suspended solids and total organic carbon (TOC) also enhance turbine and boiler efficiency.

How silica is removed in boiler? - Bayt.com Specialties

The most familiar methods for removing silica from a waste stream are lime softening, ion exchange and reverse osmosis. And there is a new method called "Electrocoagulation" which may soon move from the optional treatment method to the essential treatment method.

Silica fouling and cleaning of reverse osmosis

Reverse osmosis (RO) is by far the most efficient way to remove colloidal and dissolved silica, which can be found in high concentrations in brackish water. The presence of silica and its ability to foul membranes limits the use of silica bearing waters for desalination and when used, it has many economic penalties.
