Desalination

How desalination works?

Desalination is the process of removing salt and other minerals from water to make it suitable for drinking or for industrial use. In water-stressed areas, desalination can be a sustainable solution that eliminates the need to transport water over long distances.

Membrane-based desalination uses semi-permeable reverse osmosis membranes and pressure to separate salts from water. Reverse osmosis technology uses less energy than thermal distillation, and technology enhancements have led to a reduction in over all desalination costs over the last decade.

Ultra Filtration Plant (UF)

We offer wide range of UF systems as per customer requirement , we design Ultrafiltration plants for various applications like RO pre treatment, drinking water, ETP, STP andcustomisedrequirement.

Ultrafiltration is a separation process using membranes with pore sizes in the range of 0.1 to 0.001 micron. Typically, ultrafiltration will remove high molecular-weight substances, colloidal materials, and organic and inorganic polymeric molecules. Low molecular-weight organics and ions such as sodium, calcium, magnesium chloride, and sulfate are not removed.

Reverse Osmosis Plant (RO)

Swedo Water Tech offers Reverse Osmosis water systems from minimum 50 LPH and above RO is a highly effective water treatment process for reducing up to 99% of dissolved mineral salts, organics, and other particles by forcing water under pressure through a semi-permeable membrane. The process is named “reverse osmosis” because it is the opposite of the natural osmotic process, where water from a solution with a low concentration of dissolved solids travels through a membrane seeking to dilute a higher concentrationsolution.

All our industrial reverse osmosis Plants are carefully customized and configured to suit the individual requirement of the output water, which varies from normal drinking application to the specific

De Mineralize Plant (DM)

Our DM Plants are designed based on latest cost effective ion exchange technique of counter current regeneration. The units consist of two corrosion free pressure vessels internally connected in series. The first column containing Cation absorbing exchanger and second column charged with an anion absorbing exchanger. The water flow Pass through the bed of a Cation exchanger then the bed of an anion exchanger and the systems remove dissolved salts from water to a specified degree.

Regeneration require after using total exchange capacity. The Cation Resin is regenerated with an acid and anion resin is regenerated with alkali solution. RWT consists of acid/alkali proof pressure vessel with internal fittings and initial charge of Cation and Anion exchanger, set of regeneration equipment, hydraulic ejectors, acid and alkali tanks and conductivity meter to monitor treated water quality. These DM Plants offer a practical range of capacities and flow rates necessary to serve wide variety of applications. Standard portable deionisers are Up flow two-bed type compact and simple to operate with conductivity meter to monitor quality of treated water continuously when in operation.

De-mineralisers can be connected directly to the Raw water and can used for continuous supply or instant requirement of demineralised water.

Iron Removal Plant

A typical iron removal filter contains sand and MnO2 media to remove iron and manganese from groundwater.

It follows the oxidation process of Iron and Manganese ions.As the raw water is passed through the bed, any soluble iron and manganese ions convert to rust particles (insoluble ferric state),allowing them to filter out through filtration process.

Pressure Sand Filter (PSF)

We Design & Develop the Pressure Sand Filter sizes based on water quality to make filtration velocity through Sand Filter Medias. These filters are mainly used to remove Turbidity, TSS and filter up to 50 micron level. Filtration taking place through the filtration bed of pressure filters [known as fine filtration] removes especially turbidity, colloid substances, undesirable colour or odour, microbiological contamination, and some ammonia ions, precipitated iron, manganese from water and it reduces water acidity as well.

Activated Carbon Filter (ACF)

Activated Carbon Filter are designed and manufactured with dual filtering media like sand and activated carbon. These filters can be used as initial unit for industrial water treatment. It is also used as pre-treatment and tertiary treatment of waste water. These filters comprises of a steel pressure vessels of FRP Vessels containing activated carbon granules as filter media. Activated carbon is porous carbon material. Due to its highly developed porous structure and huge specific surface area , activated carbon has very strong adsorption capacity. It removes bad odour of water. It is used as a catalyst or catalyst carrier, to find wide applications in industrial production, agriculture environmental protection. These filters are mainly used to remove Odour, Smell, Organic Colours & De-chlorination purpose.

Effluent Treatment Plant (ETP)

Our range of Effluent Treatment Plants for recycling of wastewater to reduce water demand. The comprehensive treatment solution works at various levels and involves various physical, chemical, biological and membrane processes. We also provide effluent treatment solutions for various types of industrial waste water. Customized systems to suit the wide variety of effluents and to maintain efficiency are provided to industries.
