The Steel Tank Institute's white paper on keeping water out of your storage system. Covering:
♦ The Economic Impact on Your Business
♦ How Water Gets Into a Storage System
♦ Preventive Operations & Maintenance Practice
Meeting the food requirements of a growing global population is becoming increasingly difficult. Despite the need for additional food, it is estimated that 50-60% of grain is lost after harvesting, at a cost of about $1 trillion per year.1 One of the major reasons for lost grain is spoilage due to mould or insect infestation during storage.2 To provide a constant supply of grain year-round, after grains are harvested they are often kept in long term storage. Maintaining the quality of stored grain is crucial,...
Fast decline of groundwater levels in Pakistan requires the use of artificial recharging techniques to minimize the adverse effect of over pumping. A study was conducted in the Toba Tek Singh district, Punjab, Pakistan, to investigate aquifer storage and recovery (ASR) technology to recharge groundwater. The facility was developed by drilling a pumping/injection well and constructing the water storage tank along with developing the recharge mechanism. Three treatments of 51, 71, and 99 m3 of treated canal water...
When purchasing a bolted steel tank or a welded steel water storage tank, one of the key criteria determining the design parameters of the tank is the Seismic Use Group (SUG) classification. The term Seismic Use Group is essentially the same as the terms Occupancy Category and Risk Category used by the International Building Code (IBC) and the American Society of Civil Engineers (ASCE). The Seismic Use Group classification is used to determine the magnitude of environmental loading applied to the bolted or welded...
Reduction of leakages in water distribution systems (WDSs) is one of the major concerns for water industries. This paper presents a leakage reduction technique using pressure management by optimizing the water level in storage tanks, along with optimized control and localization of pressure-reducing valves (PRVs) in WDSs. A new mathematical tank and pump simulation algorithm is presented for controlling pressure in WDSs, by optimizing the water storage level in the tank depending upon the demand variations. The...
The level of groundwater has fallen dramatically in the plain, and several obvious cones of depression in the groundwater surface around waterworks have expanded, because of groundwater over-drafting in Beijing. This condition has led to reductions in available groundwater resources, and has even restricted the economic development of Beijing. However, an opportunity has been provided for groundwater recharge, since considerable storage space has been created by this overexploitation. At the beginning of the...
