“…Chemical Oxygen Demand (COD). The COD concentration was 205 mg/L which was produced majorly from the fish activity, feeding techniques and heterotrophic organisms (bacteria and fungi) (Nora'aini et al 2005). The treatment container with Eichhornia crassipes (non aeration and aeration) had highest reduction percentage 59.02% and 58.86% while Pistia stratiotes (non aeration and aeration) were 53.82% and 56.91% (Table 2).…”

“…Various systems had been introduced for treatment of aquaculture wastewaters such as settling systems, centrifugal systems and mechanical filters (Evans and Furlong 2003). However, these methods could only achieve partial performance with clear disadvantages of producing considerable sludge deposits, high energy consumption and require frequent maintenance (Nora'aini et al 2005). Stabilization ponds were utilized for fish culture with simple sedimentation basins or emergency holding tanks which were successful in BOD removal only.…”

Water hyacinth (Eichhornia crassipes) and water lettuce (Pistia stratiotes) were analyzed to determine their effectiveness in aquaculture wastewater treatment in Malaysia. Wastewater from fish farm in Semanggol Perak, Malaysia was sampled and the parameters determined included, the pH, turbidity, dissolved oxygen (DO), chemical oxygen demand (COD), biochemical oxygen demand (BOD), nitrite phosphate (PO4(3-)), nitrate (NO(3-)), nitrite (NO(-2)), ammonia (NH3), and total kjedahl nitrogen (TKN). Also, hydroponics system was set up and was added with fresh plants weights of 150 +/- 20 grams Eichhornia crassipes and 50 +/- 10 grams Pistia stratiotes during the 30 days experiment. The phytoremediation treatment with Eichhornia crassipes had pH ranging from 5.52 to 5.59 and from 4.45 to 5.5 while Pistia stratiotes had its pH value from 5.76 to 6.49 and from 6.24 to 7.07. Considerable percentage reduction was observed in all the parameters treated with the phytoremediators. Percentage reduction of turbidity for Eichhornia crassipes were 85.26% and 87.05% while Pistia stratiotes were 92.70% and 93.69% respectively. Similar reductions were observed in COD, TKN, NO(3-), NH3, and PO4(3-). The capability of these plants in removing nutrients was established from the study. Removal of aquatic macrophytes from water bodies is recommended for efficient water purification.

“…However, excessive amounts of degradable organics in water bodies is dangerous to aquatic life since microorganisms utilize dissolved oxygen in water to degrade the organic products. This results in a competition for dissolved oxygen between organisms and aquatic life that deteriorates the overall water quality [11,12]. Moreover, the organic compounds found in agricultural, textile and food industry wastewater are difficult to degrade.…”

Pore size analysis from retention of neutral solutes through nanofiltration membranes. The contribution of concentration–polarization

et al. 2014

Pore size distribution is one of the most important characteristics of a membrane.This can be obtained from the fitting of pore radius calculated from retention versus flux measurements for a set of solute solutions. In this work a set of non-charged similar molecules are chosen as solutes to minimize other interactions apart of those related to size. The hydrodynamic model will be used to characterize the behavior of the membrane to uncharged solutes, assuming that membrane pores are straight and cylindrical.As is known, the phenomenon of concentration polarization must be taken into account because true retention is not experimentally accessible by concentration measurements. Frequently, the film layer model is applied for the dependence of
