The present study investigated the coupling effect of biodegradation and media filtration in treating hydrocarbon contaminated water. The study recorded reductions in total petroleum hydrocarbon, total dissolved solids, turbidity and microbial load. The study was essentially a simulated pump and treat process that involved the pumping of hydrocarbon contaminated water for treatment in a locally...

Waste products such as biosolids and wood wastes have been frequently used in container production of plants. The use of biosolids in agriculture is a beneficial mean of recycling the by-products of waste-water treatment. However, care must be taken to avoid environmental or human health problems via run-off and leaching. The objective of this work is to compare the retention capacity of cadmiu...

The adsorption process is being widely used by various researchers for the removal of heavy metals from waste streams and activated carbon has been frequently used as an adsorbent. Despite its extensive use in the water and wastewater treatment industries, activated carbon remains an expensive material. In recent years, the need for safe and economical methods for the elimination of heavy metal...

Preparation of bentonite clay–coconut husk composite (BECH) via microwave-assisted carbonization, the activation BECH with HCl (BECH-H) and KOH (BECH-K) adsorption ciprofloxacin, tetracycline, bisphenol A from aqueous solutions.

The main objective of this study is to use coconut husk produce mortar for ferrocement. Mortar mix proportions are selected per ACI codes’ recommendation and the WRD Handbook. Four types mortars: Cement River Sand (CSM), Cement, Steel fibre (CSSFM), Coconut Husk (CCHM), (60%), (40%), (CSCHSFM) used Microstructural studies like SEM, EDX, XRD, FTIR analysis on cement constituents mixes studied re...

A horizontal drum kiln is a traditional method widely used in Southeast Asian countries for producing biochar. An understanding of temperature conditions the and its influence on biochar properties crucial identifying suitable applications. In this study, four agricultural residues (corncob, coconut husk, shell, rice straw) were production. The turned into within 100–200 min, depending their st...
