The rice husk contains about 75% organic volatile matter & the balance 25% of the weight of this husk is converted into ash during the firing process, is known as rice husk ash (RHA). This RHA in turn contains around 85%-92% amorphous silica. Silica is one of the valuable inorganic chemical compounds.

In this paper we review the speciation of silica in feedwaters, and chemical approaches to controlling fouling and maximizing silica reduction. Silica and silicates are addressed in the three categories of reactive soluble, non-reactive soluble (colloidal, not filterable) and non-reactive insoluble (particulate, filterable) forms.

A. Silica can be removed from raw water easily with standard demineralization techniques. Normally silica is present in a weak acidic form. Ion exchange will remove this as long as the anion resin is the strong base type. Silica in deionized water can easily be reduced to 20-50 ppb. Reverse osmosis will also remove silica by 90-98%.

The scaling and fouling behaviour of silica is varied. In those plants operating with high silica concentrations of over 200 mg/L as SiO 2 in the reject, scaling will occur in the rear elements unless specific silica antiscalants are dosed. In most cases silica deposits are amorphous due to the dosage of polymeric based dispersants.
