TREATMENT OF DOMESTIC WASTEWATER BY SOIL TRENCH SYSTEM

5 Amount of coating reduced through opacity improvement
Why would the use of specialized base coatings on inner panels reduce the amount of coatings used? One of the properties of a coating is opacity 3 . If the opacity of a coating is weak,[r]

stabilized material still contains the toxic pollutants, the SS material will need to be contained in a secure landfill.
The question of whether one only needs to produce a stabilized product — as opposed to the solidified product — is a question that is resolved by regulatory requ[r]

T-C and T-N contents in MSL systems after 2 years operation
Figure 3 shows the T-C and T-N contents in soil mixture layers and zeolite layers at each depth of MSL1, 3 and 6. Since MSL6 was discharged the river water 4 times as much as MSL1 and 3 did, T-C content in MSL6 was higher th[r]

The objective of this study is to develop an energy and nutrients recovering wastewater treatment process combining physicochemical and biological methods for NRP wastewater.

Uncontrolled urbanization of African cities and the lack of municipal waste mana gement services in these cities make landscapes become places of multiple and varied interactions between health and environment. In this sense, under strong urban growth in a context of sub-equipment sanitation, the ci[r]

The treated industrial wastewater has been, continuously used for crop production in the water scares region of our country. Irrigation with agro-based industrial wastewater (treated paper mill effluent) though it initially increased the yield of many crops, over a period; it deteriorates the soil q[r]

These periods were selected in order to verify if fungal biomass had an effect on the activities of enzymes in their growth medium. One could observe that at 7, 14 and 31 h , the suspended solid concentration in the bioaugmented reactor was respectively ,

Nitrogen is the key nutrient factor that influences soil fertility and productivity. It is the mineral nutrient that exists in different forms, but nitrate form is the most preferred form by plants. Irrespective of the form in which N is applied to soil, it undergoes transformation viz. mineralizati[r]

There are two basic steps in the wood preserving process: (a) preconditioning the wood to reduce its natural moisture content and to increase permeability; and (b) impregnating the wood with the desired preservatives.
The preconditioning step may be performed by one of several method[r]

SS concentrations in effluent decreased by installing biofilm inside the circulation tank (Run 3) as shown in Figure 3. However, DOC concentrations increased as shown in Figure 2. Higher DOC in Run 3 than Run 2 was probably due to the insufficient DO. Although twice as large amount[r]
