PRE-TREATMENT

Pre-Treatment is the main water purification process. All types of wastewater treatment plants require this basic step to move forward. The purpose of the pre-treatment is to physically remove most insoluble solids to reduce the load of contaminants. We offer a variety of filtration technologies, including back washable filters that remove chemicals, metals, gases, and particulate matter.

REVERSE OSMOSIS

Reverse Osmosis System is the process for separating particles dissolved in water, such as salt. It removes particle residues and neutralizes the taste. These systems use semipermeable membranes to filter dissolved contaminants and solids based on the water pressure applied to the membrane. They can remove up to 98 percent of pollutants from water. We offer a variety of under-the-sink or Point of Use (POU) units as well as home-wide reverse osmosis systems or Point of Entry (POE) systems.

FILTRATION SYSTEM

Filtration is an important step in water treatment. Filtration in water treatment completely removes solid particles from the water. This can be groundwater, surface water, or even pretreated wastewater. These processes in water treatment have clear goals. It is to provide the right water quality for a particular industrial application. Media-based filtration works by the media, creating a barrier against the passage of suspended solids and absorbing some compounds contained in the liquid. Membrane filtration includes ultrafiltration and reverses osmosis, which can retain various types of ions and allow pure water to flow. It also uses a filter cartridge that acts as a protective barrier to hold solids and particles upstream.

DISINFECTION

Though the water may look very clear, it can consist of bacteria & other pathogenic micro organisms which are harmful. That’s why the disinfection stage is a must step to incorporate. FloWater covers a range of UV lights, filters, chlorination, and ozonation systems. These systems sterilize water by eliminating or killing pathogenic biological matter. As per the ECR97 guideline, in the sewage treatment plant, the number of Total Coliform per 100ml should be 1000 after disinfecting. We design our plant to ensure that it meets the limit of the guideline.

COAGULATION-FLOCCULATION

Coagulation-Flocculation is a suspended solids removal process in a water treatment plant. Here, chemicals are used to extract and clamp dissolved colloidal and suspended solids. This process uses PAC (Polyaluminum Chloride). The dose of PAC should be changed according to the water quality. After coagulation, the flocculation process takes place. This step is necessary for the proper sedimentation of small particles. This process transforms a turbid suspension of particles into a turbid suspension of large particles called flocs. Then use a sludge pump to remove these flocs.
