GREEN FACTS : Greywater Recycling ? Greywater recycling includes the reuse of household water from dishwashing, laundry, sink and shower as well as the catchment and rainwater. ? Greywater systems to catch and reuse the water can be simple and manual or automatic and gravity fed. Several Greywater recycling designs are available that can be implemented based on the extent of open ground available. ? Gravity-fed systems by design direct Greywater from indoor plumbing into the holding tanks outdoors similar to rainwater catchment. ? In a garden, a large Greywater tanks or an array of up-cycled barrels setup outdoors can save Greywater optimally. ? A sink can be retrofitted for collection by removing the plumbing underneath and replacing it with a water catchment device. ? For HVAC consider a Greywater heat recovery system. This saves water as well as energy. ? In commercial kitchens Greywater form steam tables and steaming equipment can be used for cleaning the countertops or floors at the end of the day. ? To eliminate concerns about the presence of chemicals in Greywater, steer clear of chemicals and switch to plant-based, phosphate-free cleaners. ? To compact garbage, install a pulper that used recycled water to compress organic water. ? Greywater may also be fed directly into an outdoor pon / series of ponds. The ponds, channels and swales can help disperse water throughout the garden. ? Greywater recycling designs usually consist of a system for collecting water from washbasins and kitchen sinks and some simple filtration chambers. Different types of filtrations are possible, from using river sand to charcoal to even tuberplants. ? Bio-Membrane-Technology (BMT) with membrane of 38mm filter pore size is a chemical free treatment process using the latest technology for Greywater recycling. è ? Greywater Treatment and reuse systems (GWTRS) which operate on eco-friendly † biological process purify treated water using mild disinfection & adsorption and micro ´ filtration process. ñ £ Selection of finishing techniques for stone floors. ù ? For various surfaces, finishes have different uses. E.g. when a lineare finish is used for Š steps, it acts as a antiskid or when a leather finish is used in bathroom walls or ªð flooring, it not only enhances the look of stone by also avoids slipperiness. £ ? Polished : Limestone, marble, and granite floors are commonly polished to enhance P ò their appearance. £ ? Honed : Honed finishes present a softer, flat matte appearance that shows fewer ÷ scratches, and is easy to maintain. Slate, marble, and limestone do well with this type ˜ of finish. fl;Lkhdg; nghwpahsh; 28 mf;Nlhgh; 2013
