Density of wastewater sludge
WebThe dissolution of soluble metal compounds from ore and waste rock as well as the presence of contaminants in industrial process water can result in metal contaminated effluent. These dissolved ions are commonly precipitated using a lime neutralization pr ocess, which produces a low density sludge that is difficult to thicken and filter. WebEXAMPLE 1 - AGRONOMIC AND ECONOMIC BENEFITS OF WASTEWATER USE IN IRRIGATION. As an example, a city with a population of 500,000 and water consumption of 200 l/d per person would produce approximately 85,000 m 3 /d (30 Mm³/year) of wastewater, assuming 85% inflow to the public sewerage system. If treated wastewater …
