RIVA APPLIANCES PVT.LTD Multimedia Filter- RIVA offers wide series of multimedia filters for removal of suspended solids and heavy metals. Filters are available FRP (Fibre Reinforced Polymer), Mild Steel and Stainless Steel. 
Pressure Sand Filter- Pressure Sand Filter is an ideal solution for the systems with high sediment, silt, sand, and turbidity. Our unique design ensures the maximum utilization of the surface area, lesser pressure drop across the pressure bed and effective elimination of the impurities. The strength, stability and micro-porous character of filtration media make sand filter suitable for virtually every application in the water treatment industry. 
Activated Carbon Filter- Activated carbon is the most common method of treatment for de-chlorination and removal of taste and odour from water, through adsorption. Adsorption is directly related to the surface area of the media.
Iron removal Filter- Iron removal filter is processed catalytic filtration unit where the raw water passes through the layer of compressed air, processed catalyst & quartz filter media respectively. The dissolved ferrous iron salts are converted into insoluble ferric salt and precipitated over the filter bed and then the iron free filtered water comes out.
Bromide Removal Filter- AGUAPURO offers Bromide removal Filters for various capacity ranging from 10 M3/hr upto 250 M3/hr.  Water containing Bromide when ozonated, produces Bromate which is carcinogenic.  The level of bromate is allowed upto 20 ppb in Drinking Water.  However, AGUAPURO offers systems to reduce Bromide from water to avoid Bromate transformation post Ozonation.  The removal is possible up to 5 ppb level.
Manganese removal Filter- Manganese produces a brownish colour in laundered clothing, leaves black particles on fixtures and as with iron, affects the taste of beverages, including coffee and tea. Aguapuro specializes in manganese removal systems to help water treatment plants deal with these problems.
