Many researchers have focused on utilization of coal fly ash for manufacturing of potassium fertilizer, zeolite, cement, flue gas adsorbent concrete, raw material for road structure and bricks making, reactive dyes, adsorption of phenolic compounds, organic compounds, heavy metals and organic pollutants from industrial flue gases and effluents
. It was acknowledged from effluents
analysis of dyes manufacturing plant, that these industrial effluents
contain high concentration of organic pollutants such as BOD, dyes, COD, phenolic compounds, color, TDS, turbidity and suspended solids.
In Table 2, a summary of the periods of application and the amount of water and effluents
applied in the treatments with effluents
(NE, NE+F, AE and AE+F) is presented.
Cassava mill effluents
and rubber effluents
had the highest and same number (7) of bacterial isolates, while oil palm mill effluents
had the least number (6) of bacterial isolates.
After that, polyethylene containers of 12.5 L capacity and 268.8 mm bottom sections were filled with each by-product and sealed, except for a device at the base to collect the effluent
not only increase the nutrient level, but also multiply the tolerance limits and hence causes potent toxicity (Mishra et al., 1999).
In the current study isolation and screening of the indigenous bacteria was carried out from textile effluent
contaminated sites and bacterial consortia were developed to reduce the pollution parameters from textile effluents
discharge license, Osumo pointed out, stipulates conditions under which treated waste is to be discharged.
lucidum IBL-05 (GL) were used for the decolorization of synthetic dyes effluent
The city produces an estimated 450 million litres of municipal sewage and industrial effluent
daily, a majority of which was flowing directly into the holy river until recently.
Many methods have been developed to remove chemical substances found in industrial effluents
discharged directly in to environment (Mehmet et al., 2003; Raghu and Ahmed-Basha, 2007).
Textile industrial wastewater also shows toxic effects on aquatic macrophytes and algae, as it is noticed that, aquatic macrophytes could hardly survive two days on textile effluent
