TL;DR: Experimental results showed that the process of CEPT and TF in series was beneficial for the removal of hydrophobic and hydrophilic organics.
Abstract: To find a simple and economical way for treating the domestic wastewater in small counties and towns, a process combining chemically enhanced primary treatment and a trickling filter (CEPT-TF, representing the physical and biological effects) was constructed and operated in laboratory conditions. The characteristic behaviors of dissolved organic matter in raw wastewater and effluents were examined during steady-state operation. Experimental results showed that the process of CEPT and TF in series was beneficial for the removal of hydrophobic and hydrophilic organics. Specially, the hydrophobic and aromatic materials could be preferentially removed in the CEPT unit, and the hydrophilic fraction in the TF. Structural changes of the organic fractions during the operation of the different units were also characterized via spectrum analysis.

18 Nov 1993TL;DR: In this article, a system for water quality control and improvement in intensive fish culture systems is described, where the aim of the water treatment is to reduce the content of inorganic nitrogen and of organic matter.
Abstract: There is provided a system for water quality control and improvement in intensive fish culture systems. The aim of the water treatment is to reduce the content of inorganic nitrogen and of organic matter. The system comprises a fish pond, a settling pond, a fluidized bed reactor and a trickling filter. The system according to the invention can be an essentially closed one, except for periodic water replenishment. It is suited for ponds with sweet or salt water.

TL;DR: The kinetic mechanisms of purifying waste gas containing toluene in low concentrations were investigated by using a biological trickling filter packed with biofilm packing-material and an ‘Adsorption-Biofilm Theory’ and associated kinetic model were established.
