Wastewater Treatment Methods

Increasing global population intensifies the food demand pressure while meeting the increasing environmental legislation. To cater for such demand, agriculture sector shifts for mass food production accompanied with the use of a large amount of agrochemicals such as fertilizers, pesticides, antibiotics, and growth hormones. As a result, these agrochemicals' residues pollute the ecosystem and environment through surface runoff. It has been a great challenge in treating agricultural runoff due to its contaminant loadings and wide variability of different compounds in the wastewater to meet the stringent standards in an economically feasible manner. This chapter delineates the current state-of-the-art of wastewater treatment methods for agricultural runoff.

The Impact

Several aspects of using ashes from sewage sludge incineration in the brick and tile industry have been examined. After discussing the item of ash production in Germany, the impact of different wastewater treatment methods is described; for instance, the use of precipitation agents containing iron will considerably influence the ash quality. Depending on their respective chemical composition, different ashes have different effects on the ceramic qualities of the bricks made of clay blended with ashes. These effects will be shown in regard to the major ceramic parameters. Similarly, the quality of the ashes also influences the elution behaviour and the mineral fixation of heavy metals.

Refining Equipment

Traditional chemical-machinery producing mainly took the refiner as the primary refining equipment. Extrusion pulping was the reformation of traditional refining pulping. The different equipments and processes resulted in the different characteristics of wastewater inevitably. This article aimed to compare the characteristics and biochemical treatment methods between conventional chemical-mechanical pulping and extrusion pulping, and then discuss the biochemical treatment advantages of extrusion pulping wastewater. The result shows that: the wastewater from the extrusion pulping has lower concentration of tiny fiber, load suspended matter, wastewater temperature and effluent discharge. And thus make a simpler process, a lower cost and a better effect of the wastewater treatment.
