Reuse of water and low cost, this is because the saving water resources, water and energy costs of long distance water transportation and infrastructure costs. Third, urban wastewater reuse for agricultural production and green, will bring considerable environmental benefits. Because the water is generally used, so a long-distance pipeline transport of fresh water, low cost, and secondary treatment of urban wastewater reuse, also reduces emissions to the waters, bringing considerable environmental benefits, the environmental and economic benefits are unified. The outdoor water reduction has a couple of ways to achieve it • Soil improvement Retention of poor soil by mixing aqueous organic soil and add water retention polymers to improve…show more content…
Installation of water meters is the most effective way to know the situation. The principle is according to categories such as wash water, toilet flushing water, swimming pool water and irrigation water to install water meters per each. However, in fact, it is very difficult to achieve, so alternative way is installed at least one meter in each separate building. Cooling tower means water through a heat exchanger to achieve cooling water. Cooling tower water constantly recycled after cooling, the dissolved solids and suspended solids concentrations in water continues rising. When dissolved solids over a certain value, the deposition phenomenon must occur. At this point, it must be discharged to reduce the content of dissolved substances within a certain range, by adding new water to blend the concentration of cooling circulating water contains dissolved substances. Therefore, the cooling cycle water must increase the concentration to reduce its emissions to achieve the goal of saving water. Water recycling is the most direct and simple and easy, works fast to save water resource technology roadmap. Saving water at the same time can obtain protection of the water environment results. Take energy-saving cooling tower technology. To expand the scope of the use of recycled water, and reduce the cost of operation of circulating water, makes strategic sense and considerable economic benefits. Water-saving affects as opposed to say the water-saving effect is
