Impact of sample pretreatment on the results of texture
To quantify the effects of the pretreatment method on soil parameters estimated from soil textures, we derived the effective cation exchange capacity (CEC eff), air capacity (AC, pores with >50 µm diameter), plant available field capacity (aFC, pores with 50–0.2 µm diameter), not plant available water capacity (naW, pores <0.2 µm diameter) and saturated hydraulic conductivity (k s) for
A.A. Refaat, in Comprehensive Renewable Energy, 2012. 5.13.4.7.1(i) Goals of pretreatment. The pretreatment is a necessary step to alter some structural characteristics of lignocellulose, increasing glucan and xylan accessibility to the enzymatic attack. The aim of the pretreatment is to break down the lignin structure and disrupt the crystalline structure of cellulose for enhancing enzymes
Pretreatment of a dyeing wastewater using chemical coagulants
For pretreatment of the feed water of membrane processes, chemical coagulants such as HOC-100A, alum, and ferric chloride were used. The feed water used in this experiment was a synthetic dyeing wastewater composed of Direct Red 75, polyvinyl alcohol (PVA), NaCl and Na 2 SO 4.Total concentration of the materials in the feed water was 2500 ppm.

Microalgae-based wastewater treatment for nutrients
The optimal treatment condition for the mixed piggery-brewery wastewater using microalga was piggery wastewater mixed with brewery packaging wastewater by 1:5 at pH 7.0, resulting in carbon
As leaders in the sector realize the potential of wastewater, the entire wastewater treatment plant (WWTP) model is shifting to a more efficient water resource recovery facility (WRRF) model, which uses biochemical, physical, physicochemical, and biological conversion processes to extract value from previously unexploited streams.

Method of cleaning: Perc in a 3rd generation dry to dry machine installed in 1983 with refrigeration technology installed on it in 1998. e. Where we came from: original equipment was a transfer unit installed in 1958.
Removal of Target PPCPs from Secondary Effluent Using AOPs
wastewater due to its complex water matrix such as the presence of natural organic matter, color, odor, suspended solids, ions, etc. Some of the key contributions of this research helped in improving the methods of removal of PPCPs from wastewater as follows: a) Extensive wastewater sampling, laboratory experiments and data analysis by
Wastewater reuse in agriculture is regulated by the 1975 Water Code (law No. 75-16 of 31 March 1975), by the 1989 Decree No. 89-1047 (28 July 1989), by the Tunisian standard for the use of treated wastewater in agriculture (NT 106- 003 of 18 May 1989), by the list of crops than can be irrigated with treated wastewater (Decision of the Minister
