Solid/liquid separations are a mature technology area and few new developments occurred in seventies and eighties. However, last decade witnessed appearance of a significant number of new innovative systems in this field. (Rubio et al., 2002) This paper describes new developments in mixing, coagulation, flocculation and flotation systems for industrial wastewater treatment. (Ross et al., 2000; ...

The paper industry is adopting zero liquid effluent technologies to reduce freshwater use and meet environmental regulations, which implies closure of water circuits and the progressive accumulation of pollutants that must be removed before water reuse and final wastewater discharge. The traditional water treatment technologies that are used in paper mills (such as dissolved air flotation or bi...

Industries produce millions of cubic meters of effluent every year and the wastewater produced may be released into the surrounding water bodies, treated on-site or at municipal treatment plants. The determination of organic matter in the wastewater generated is very important to avoid any negative effect on the aquatic ecosystem. The scope of the present work is to assess the physicochemical c...

The wastewater generated from the pharmaceutical industry contain high organic load and the treatment are primarily carried out using two major types of biological methods; aerobic and anaerobic. However, due to high strength, it is infeasible to treat some pharmaceutical wastewater using aerobic biological processes. As an alternative, an anaerobic process is preferred to remove high strength ...

Duckweed (Lemna minor L.) has a wide application in Turkey having suitable climatic conditions. In this study, the growth of duckweed was assessed in laboratory scale experiments. They were fed with municipal and industrial wastewater at constant temprature. COD, total nitrogen (TN), total phosphorus (TP) and ortho-phosphate (OP) removal efficiencies of the reactors were monitored by sampling i...

Average concentrations of adsorbable organic halogens (AOX) in sludge from the Gaza Strip reached 600 mg kg(-1) which currently represents a major limiting factor for sludge application in agriculture. This study aims to identify the main sources of AOX in Gaza where the area is small with limited industrial activities. The results showed that the AOX in effluent sludge is formed mainly inside ...

producing biogas is the most common method of energy generation in municipal and industrial wastewater treatment plants in the world. methane production rate depends on degradation rate of organic pollutants in wastewater, temperature and treatment process. typical parameters for assessment of organic wastewater such as bod or cod indicate the potential to produce methane. there is no accurate ...

The membrane biological reactor (MBR) configuration has proven to be optimal for treatment of many industrial wastewaters when treatment efficiency is an important consideration. Since installation of the first large, U.S., full scale MBR system for industrial wastewater treatment at the General Motors plant in Mansfield, Ohio in the early 1990s, use of membranes for biomasseffluent separation ...
