Difference in the root structure of hyperaccumulator Thlaspi caerulescens and non-hyperaccumulator Thlaspi arvense

The primary root structure of Zn/Cd hyperaccumulator Thlaspi caerulescens was compared with the root anatomy of closely related non-accumulator Thlaspi arvense. The most striking structure formed close to the root tip in T. caerulescens, but not in T. arvense, is the peri-endodermal layer of cells with irregularly thickened inner tangential walls. This layer observed in some species of ...

A case study of the sludge thickener - Office Building

Costs for industrial waste reduced with sludge thickener Some office buildings and large commercial facilities have wastewater treatment facilities underground. In such case, it is difficult to take dewatered cake out, so sludge is kept in liquid form and vacuumed out by pump without being dewatered. This potential customer also had been vacuuming out the liquid sludge, and had considered how to ...

Mine backfill

Mine backfill is defined as the material used to fill the cavities (i.e., stopes) created by underground mining. Backfilling can be a means to dispose of sludge and/ or tailings which may contain hazardous materials and to reduce surface environmental impacts by storing tailings underground. Alternately, backfilling with nonhazardous materials can allow for mining productivity improvements. To ...

Huber sludge treatment plant on the black sea coast - Case study

The Bulgarian Black Sea Coast along the city of Varna with 300,000 residents is an important economic factor, especially due to its touristic potential. The European Union decided in 2002 to give aid money for the protection of the Black Sea, in particular for upgrading and building new local sewage treatment plants. The capacity of the sewage treatment plant at Varna could therefore be expanded ...

Organotin Compounds in the Three Gorges Reservoir Region of the Yangtze River

Tributyltins (TBT) are known endocrine disrupting chemicals (EDCs). It was reported that TBT at concentrations of more than 7 ng Sn/l would induce juvenile Buccium undatum to develop a penis and a vas deferens, i.e. imposex (Ten Hallers-Tjabbes et al. 2003). TBT in aquatic systems were also reported to be related to various symptoms such as thickening of shell and failure of spat in oyster ...

Paste thickener bed level measurement

Numerous studies and papers have been devoted to the subject of thickener design and operation to achieve specified throughput and discharge densities. Mathematical models have been developed that present methods for sizing thickeners and predicting performance under varying process conditions. The compression effect of deeper beds on dewatering performance is a recognized phenomenon. This is one ...

Membrane thickening aerobic digestion processes

Sludge management accounts for approximately 60% of the total wastewater treatment plant expenditure and laws for sludge disposal are becoming increasingly stringent, therefore much consideration is required when designing a solids handling process. A membrane thickening aerobic digestion process integrates a controlled aerobic digestion process with pre-thickening waste activated sludge ...

Application of forward osmosis (FO) under ultrasonication on sludge thickening of waste activated sludge

Forward osmosis (FO) is an emerging process for dewatering solid–liquid stream which has the potential to be innovative and sustainable. However, the applications have still been hindered by low water flux and membrane fouling when activated sludge is used as the feed solution due to bound water from microbial cells. Hence, a novel strategy was designed to increase sludge thickening and ...

The laminar/turbulent transition in a sludge pipeline

Globally, wastewater treatment plants are under pressure to handle high concentration sludge in a sludge treatment line. Unawareness of the non-Newtonian behaviour of the thickened sludge has the potential to cause unexpected problems when the fluid behaviour changes from turbulent to laminar flow. In this study, sludge apparent viscosity was plotted as a function of total suspended solids ...

Tailings paste disposal – more than water recovery

The minerals industry has faced increasing pressures in recent years in the management of tailings streams. Environmental, economic and other factors have led many minerals producers to explore the technology of making and using “paste.” With the increasing number of installations worldwide, this technology has proved to not only be industry accepted, but economically advantageous. ...

A simple empirical model for the clarification-thickening process in wastewater treatment plants

In wastewater treatment plants (WWTPs), activated sludge is thickened in secondary settling tanks and recycled into the biological reactor to maintain enough biomass for wastewater treatment. Accurately estimating the activated sludge concentration in the lower portion of the secondary clarifiers is of great importance for evaluating and controlling the sludge recycled ratio, ensuring smooth ...
