Alkylphenols and alkylphenol polyethoxylates are emerging hazardous contaminants due in particular to their endocrine-disrupting properties. These compounds originate from consumer products such as paints latex paints, adhesives, inks, formulation of pesticides, paper industry, textile leather petroleum recovery chemicals, metal working fluids, personal care products, washing agents, cleaners, ...

Various wastewater treatment technologies are available today and biological processes predominantly used in these technologies. Increasing systems produces large amounts of sewage sludge with variable quantities qualities, which must be properly managed. Anaerobic aerobic digestion composting major strategies to treat this sludge. The main indicators stabilization volatile fatty acids (VFAs), ...

The biodegradability of water hyacinth for biogas and biofertilizer production was studied under mesophilic conditions. effects pretreatments were also included in this investigation. It found that has a low 27% when monodigested, while 3:1 ratio with cow manure, the increases to 46%. At elevated biodegradability, biomethane potential 185 LCH4/kgVS, manure 216 LCH4/kgVS. Gompertz kinetic model ...

The use of integrated anaerobic-aerobic bioreactor (IAAB) to treat the Palm Oil Mill Effluent (POME) showed promising results, which successfully overcome limitation a large space that is needed in conventional method. understanding synergism between anaerobic digestion and aerobic process required achieve maximum biogas production COD removal. Hence, this work presents artificial neural networ...

Background: MEG is extensively applied in the sour gas industry as a hydrate inhibitor. It is toxic in oral drinking and serious injury or death may result from swallowing of pure ethylene glycol and poses a potential hazard to the environment through impact soil. Glycols are harmful to aquatic life. There is little information about the digestion of MEG in the aerobic reactor. Therefore, t...

a method to quick detect concentration of lecithin in eggs, namely microwave digestion spectrophotometry, was established in this research. the homogenate of eggs was treated with absolute ethanol to eliminate phosphate protein in eggs which could possibly affect concentration of lecithin examined. a sample then received a new way of pre-treatment, called microwave digestion, before uv-vis spec...

This study focused on waste to energy technology that utilized mono- and co-digestion of cow dung (CD), chicken dropping (ChD), rice husk (RH). The fabricated digesters were assessed for the influence temperature pH biogas production from materials used. total aerobic bacteria fungi counts with droppings had highest number day zero (1.5x107cfu/ml, 1.6x105cfu/ml 1.4x108cfu/ml, 1.2x105, respectiv...

The aerobic composting and anaerobic digestion of plastics is a promising route to recovering the multidimensional value from biodegradable single-use plastics. At present, collection, separation, management plastic waste are extremely challenging, majority these still end up in landfills or incineration facilities. This because not all can be treated using organic options (composting). In addi...
