Water Treatment
Rapid media filtration is the most often used method in drinking water treatment plants. Water is run through a medium, usually sand, letting the sand media remove any remaining particles and flocs in the water.
There are four subtypes of pressure-driven membrane filtration, each of which handles particles of various sizes. These processes include:
• Microfiltration
• Nanofiltration
• Ultrafiltration
• Reverse osmosis (RO)
Microfiltration: Microfiltration is a pressure-driven membrane filtration method for removing micron-sized particles from water. Various types of water and wastewater can be treated using this method.
We apply this process for the following applications:
• Boiler refeeds
• Clarifying and sterilizing water for beverage, food, and pharmaceutical industries
• Cooling towers
• Providing desalination pretreatments in multi-stage processes
• Potable water treatment
• Safer water discharge processes
• To optimize water re-use filtration systems in industrial and municipal settings
• Treating water at point-of-use (POU) and point-of-entry (POE) ports • Water reuse
• Wastewater treatment
Nanofiltration: This process is one of the most significant efforts in the wastewater treatment sector because it eliminates the divalent ions that make water hard, it is frequently used to soften hard water.
Ultrafiltration: Ultrafiltration is essential for total virus elimination. Ultrafiltration membranes have holes that can filter particles as small as 0.001 m from fluids. Membrane technology is used by Ultra Filtration to reject pollutants ranging from 0.01 to 0.2 microns. This process removes bacteria, pyrogens, high molecular weight dissolved particles, and other pollutants from water without eliminating beneficial minerals.
RO: Membrane filtration, also known as “reverse osmosis,” is a technique that involves forcing water through a semipermeable membrane in order to remove molecules, ions, and bigger particles. Water containing particulate or non-dissolved particles is assessed by conductivity and is frequently reported as TSS (total suspended solids). Membrane filtration uses a thin, permeable membrane or sheet of material through which water travels to remove contaminants and pollutants.
Wastewater Treatment
Wastewater Treatment is the process of transforming wastewater into water that may be released back into the environment. The activated sludge process speeds up the work of the bacteria by bringing air and sludge heavily laden with bacteria into close contact with sewage. After the sewage leaves the settling tank in the primary stage, it is pumped into an aeration tank, where it is mixed with air and sludge loaded with bacteria and allowed to remain for several hours.
Chlorination will eliminate more than 99 percent of the dangerous bacteria in an affluent if done correctly. To avoid shipping and storing huge volumes of chlorine, which is sometimes in a gaseous state, several communities now synthesize chlorine solution on site.
Dechlorination is a procedure that removes excess chlorine from wastewater before it is discharged into surface waterways in several jurisdictions. In instances where chlorine in treated sewage effluents may be detrimental to fish and other aquatic life, alternatives to chlorine disinfection, such as UV radiation or ozone, are being employed.
