Small Scale Application of MBR Technology

MBR technology can also be applied at the very small scale (household), replacing low-level technologies such as Imhoff tanks and maintaining BOD5 removal efficiencies greater than 99 . Matulova and Hlavinek (2009) evaluated the performance of a three-tank-in-series (each with a volume of 0.58 m3), single-household wastewater treatment plant with submerged membrane module (household MBR plant) serving a four-people family house, and comparing the response of MBR and CAS systems to different...

Nom Removal From Freshwater Supplies By Advanced Separation Technology

NICOLO ALIVERTI, ARIANNA CALLEGARI, ANDREA G. CAPODAGLIO* Department of Hydraulic & Environmental Engrg. University of Pavia,Via Ferrata 1, 27100 Pavia Italy Abstract. Natural Organic Matter (NOM) present in drinking water supplies is not known to have any direct effects on human health however, its reactivity with dissolved and particulate species significantly impacts on water quality and treatment needs. It is known nowadays that NOM can be removed by a variety of methods, including...

Introduction

Sustainable development was described by the Brundtland Commission as development that meets the needs of the present without compromising the ability of future generations to meet their own needs (Brundtland 1987), and this definition led to the development of other related concepts, such as environmental sustainability, which has become a general goal of current urban water management (Marsalek et al. 2008). When applying the sustainability concept to urban areas, it is helpful to address...

Result and Discussion

The ammonium in water and wastewater can be toxic to the aquatic life and should be removed to prevent environmental pollution. Several processes are currently used for the removal of ammonium from aqueous solutions. Ion exchange with natural zeolites is among the methods most commonly employed. Zeolites (also zeolite tuff and volcanic tuff) are materials known for they ability to remove ammonia preferably from waste water (Lahav and Green 1998 ECWATECH-2000). One of the aims of this work is to...

Sustainable Use Of Wastewater And Sludge In Jordan Residues Of Persistent Organic Pollutants A Review

Prince Faisal Center for Dead Sea, Environmental and Energy Research. Mutah University, PO Box 3, Karak 61710, Jordan Abstract. Water scarcity is the most important natural constraint to Jordan's economic growth and development. Jordan has very limited water resources which are classified among the lowest per capita worldwide. Two thirds of our water resources are currently used for agriculture therefore, wastewater reuse is one of the priorities listed on the Jordanian water strategy for the...

Results and Discussion

Several studies have been carried out in Jordan concerning wastewater and sewage sludge quality and reuse. However, limited number of those studies concerned with persistent organic pollutants (POPs). The following sections discussed the occurrence of some priority organic pollutants and their environmental risk for reclaimed water and sewage sludge reuse on agricultural land. This paper is aimed to give a future prospective toward the obstacles and limitations to wastewater and sludge reuse in...

Experimental Investigation of the Sorption Efficiency

An experimental investigation has been carried out in the dynamic sorption regime according to the methods described in Yurkov and Yurkov (2002). Granules of the natural basalt tufa (diameter 1-2 mm) and the tufa granules modified with MnO2 have been used in the experiments. Chemical modification has been performed according to the methods Yurkov and Yurkov (2002). Results of the iron (II) sorption efficiency by the natural and modified tufa and the concentrated MnO2 are represented in the...

Thermal Purification Processes

High temperatures have a marked effect on all types of microorganisms. At high temperatures, vegetative cells die due to protein denaturalization and hydrolysis of other components. In water, bacteria die between 40 and 100 C while algae, protozoa, and fungi die between 40 and 60 C. Spores require extreme heat conditions to be destroyed 120 C in wet heat (steam) for 20 min or 170 C in dry heat for 90 min (Caslake et al 2004). Boiling is one of the most effective and accessible methods for water...

The Impact Of Ignalina Nuclear Power Plant Waste Water On Lake Druksiai Before The Decommissioning Of The Plant 20072009

DANUTE MARCIULIONIENE*, DANGUOLE MONTVYDIENE, RICARDAS PASKAUSKAS Nature Research Center, Institute of Botany, Zalim ezer 49, LT-08406, Vilnius Lithuania Abstract. Ignalina NPP (INPP) is located at Lake Druksiai utilized as cooler. Like Chernobyl NPP, INPP was equipped by RBMK-1500 type reactors. One unit was decommissioned in 2005, the other in 2009. The aim of this study was to evaluate activity concentration of radionuclide's in bottom sediments and macrophytes from the waste water (WW)...

MBR Applications in Large WWTPs

Nowadays MBR's are being designed for plants as large as 120,000 m3 d average flow. While many issues are the same regardless of size, the design of a large scale MBR facility has increasing complexity due to the complications of solids treatment, flow variation, and end-of-the-line reliability issues. Currently, one of the largest operating MBR installations in the United States is the Broad Run Water Reclamation Facility, a new 42,000 m3 d plant located in the Dulles Area Watershed, upstream...

Comparison of Different kinds of Sewerage

If we suppose, that the demand for water for one person is 150 l day, then wastewater can be characterized in the following way BOD5 400 mg.l-1, CODCr 800 mg.l-1, Ntotal 70 mg.l-1, Ptotal 15 mg.l-1, solids total 1,200 mg.l-1, dissolved solids 830 mg.l-1, suspended solids SS 370 mg.l-1. The rate of CODCr BOD5 is usually 2. The proportion of C N P in wastewater, usually quoted as CODCr N P or BOD5 N P is very important for biological treatment. The efficiency of biological treatment may be...
