Water Reclamation and Reuse

Evaluation of reclamation technologies for wastewater reuse

Reclamation and reuse of wastewater require the use of tools that minimize risks to health and natural ecosystems. There are various types of such tools, among which HACCP (hazard analysis and critical control points) and barrier systems are gaining importance. The research reported here aims to determine and evaluate the most efficient combinations of different treatment systems—barriers—for t...

Just-in-Time Compiler Assisted Object Reclamation and Space Reuse

Garbage collection consumes significant overhead to reclaim memory used by dead (i.e., unreachable) objects in applications. This paper explores techniques for compiler assisted object reclamation and allocation on an actual JVM. Thereinto, the just-in-time compiler identifies dead objects using pointer and escape analysis combining liveness information and inserts calls to free them. The garba...

Specific Options in Biological Wastewater Treatment for Reclamation and Reuse

Reclamation of streptococcal cells for reuse in adsorption of antisera.

One of the major problems in the production of diagnostic antisera for the specific Griffith types of Lancefield Group A hemolytic streptococci is the accumulation of sufficient volumes of cells for adsorption processes. To minimize this problem a procedure was developed for the reclamation and reuse of the adsorption cells. The technique is as follows: Packed cells, after use for adsorption, a...

Membrane Biological Reactors (MBR) and Their Applications for Water Reuse

The term 'membrane bioreactor' expresses a combination of activated sludge and membrane separation processes. The need to processes like sedimentation and disinfection used in common methods is eliminated through MBR systems in a way that membranes are placed into or out of an aeration tank and the vacuumed wastewater created by the suction pump is pulled up from inside the membranes and leaves...
