An experimental trial was conducted at Dhabeji area to see the effect of chemical industry waste (organic with heavy metals) on seed bank of barren area of Dhabeji. An industrial sludge and its ash content were used in different concentrations, 10Kg and 20Kg sludge, 10kg and 20kg ash respectively to see the effect on seed bank, germination and growth of wild plants. After rainfall 17 species ap...

The sewage sludge production in Egypt is rapidly increasing resulting from the continuous increase of population, urban planning and industrial developments. This sludge needs to be adequately treated and environmentally managed to reduce the negative impacts of its application or disposal. Therefore, the main currently pressing needs are to find/develop more efficient, economical and sustainab...

Sewage sludge is used as fertiliser and contains nutrients required for plant growth. It also contaminants that can leach into crops. The effects of sewage on kale plants were investigated. Mixture ratios 50:50 20:80 soil prepared. soil-sludge blends analysed selected metal residues. Kale seedlings 10-13 cm planted the different combinations. Leaf lengths measured 21 days post transplanting fou...

A 162-day pilot-scale operation for reclamation of urban wastewater was studied by using an ultrafiltration membrane bioreactor (UMBR). Performance of the UMBR was investigated with a sludge retention time (SRT) of 5, 15, and 30 days, a hydraulic retention time (HRT) of 5 h, and membrane flux between 75 and 150 l m−2 h−1, respectively. It was observed that the highest sludge concentration in th...

Better understanding (and so better control) of the stickiness phenomenon of drying sludge is critical for proper operation of a variety of industrial dryers, as is the case for the combined centrifuge-dryer system used on the Monsanto Europe site in Antwerp, Belgium. In this paper a binary logistic regression analysis is performed on a 4-years data base, which resulted in an empirical model fo...

In Sweden, municipal sewage sludge are not applied as nutrient supply on agricultural land used for crops for human consumption, due to a resistance among consumer, farmers associations and leading producers and grocery distributors. Thus, a nationwide initiative, ReVAQ, with a wide range of different stakeholders was established in 2003. The aim was to identify approaches to be implemented to ...

Here we present a draft genome of Pseudomonas stutzeri strain KOS6. This strain was isolated from industrial hydrocarbon sludge as a diazotrophic microorganism. It represents one of the major parts of the culturable community of the waste and has potential importance for phytoremediation technology.

Microbial fuel cells (MFCs) are devices that exploit living microbes for electricity generation coupled to organics degradation. MFCs are expected to be applied to energy-saving wastewater treatment (WWT) as alternatives to activated-sludge reactors (ASRs). Although extensive laboratory studies have been performed to develop technologies for WWT-MFCs, limited information is available for compar...

The agro-industrial sludge, tested in this work, comes from a biscuit factory (France). Initially, it contains 3 % w/w of dry matter. The actual treatment by centrifugation dewaters it to 13 % w/w of dry matter. Electroosmotic dewatering under pressure (EOD) was investigated, as an alternative technology of mechanical treatment, to improve dewatering. This electrical treatment efficiency depend...
