  • Filters

    Sand, Activated Carbon, Multimedia and Greensand Media – choice of a filter depends upon the quality and source of water. Ideally for river water filters are placed after clarifier. For deep well water, as the suspended solids are much lesser compared to river water one can design system with filters as pre – treatment without clarifiers. Sand Filter and multi media filter are used for removing traces of TSS while activated carbon filter is used to remove color and organics. Green sand media filter is chosen when Fe and Mn are higher in the raw water.

  • 17.membrane-bio-reactors

    The membrane bioreactor (MBR) is the combination of a membrane process like micro filtration or Ultra Filtration with a suspended growth bioreactor, and is now widely used for municipal and industrial waste water treatment with plants. The derived effluent is of high quality enough to be discharged to coastal, surface or brackish waterways or to be reclaimed for urban irrigation. Other advantages include small footprint, easy retrofit and upgrade of old wastewater treatment plants.

    Southern Chemicals & Engg meets the diverse needs of municipalities through market leading technologies and processes design and build capabilities. As the percentage of the population that is served by piped water has decreased in recent years, because of rapid population growth compared to the number of connections we are constantly evaluating the opportunities presented in partnership with various industry contractors and water operators.

    One such opportunity which presented itself was through a local government in Sumatera Island. The vast stretches of inland areas have little or no access to roads and this increased the transportation costs of basic necessities. With the availability clean drinking on location the government is able to cheaply satisfy a very basic need of man.

    At Southern we are always looking to improve and further develop these community based solutions by working closely with the end users requirements.
