Activated Carbon Filter is used to adsorb chlorine, organics, tri-halo methane (THM), taste, odour, and colour from Water & Wastewater. Activated carbon filtration is an adsorptive process in which the contaminant is attracted to and adsorbed onto the surface of the carbon particles. The efficiency of the adsorption process is influenced by carbon characteristics (particle and pore size, surface area, density, and hardness) and contaminant characteristics.

Pressure Sand Filter is used for removal of suspended solids & turbidity from Water & Wastewater. Raw water is passed through the pressure sand filter, the filter media (Fine quartz sand) is supported on gravel & pebbles bed of progressively larger sizes. During the filtration cycle, the filter bed retains the dirt and suspended particles from the water and accumulates within the filter bed. The clear water can be collected from the outlet of the filter.

Iron is a common problem in water, especially well water. Iron-bearing waters are often noticeably orange in colour, causing discoloration of laundry, and have an unpleasant taste which is apparent in drinking and food preparation. The maximum recommended level of iron in water is 0.3 ppm (mg/L). Our Iron removal plants can be based on different filtration media, depending on the iron and manganese concentration, the oxygen level, CO2 content and hardness of the water.

Depending on the media selected, other common processes such as ozone, aeration, chlorine or peroxide injection may be used to boost the oxidizing properties of the water being treated. Most iron filtration systems operate on the principal of oxidizing the iron (oxidation) to convert it from a ferrous (dissolved or soluble) to a ferric or undissolved state. Once in the ferric state, iron can be filtered.

Filtration media choices are
• Sand + MNo2
• Purolite media
• Birm Media
• Katalox media etc
