Abstract In aquaculture systems, insufficient nutrients impede shrimp growth while excessive amounts of nutrient inputs lead to environmental degradation and unnecessary high investment. A study in-out budgets in an intensive Litopenaeus vannamei farm was conducted this work measure the amount nitrogen (N) phosphorus (P) input output from system. The feed conversion ratio (FCR) obtained determine level performance. Between September December 2017, monthly water sediment samples were taken...
Abstract The study investigates residents’ behavior towards reducing the use of single-use plastic (SUP), specifically in context food packaging. widespread view holds that pro-environmental (PB) results from a person’s moral and rational deliberations. In (SUP) consumption waste, relative roles rationality morality models validating PB among rural urban residents are not yet clear. this empirical study, we compared efficacy two for explaining people’s SUP reduction behavior: theory planned...
This research investigated pyrolysis as a potential method to manage plastic waste in Sichang Island, Thailand. Pyrolysis was chosen convert into fuel oil using Al–Si catalysts derived from cogon grass. The study consisted of three stages. first stage determined the composition plastics found Island. High-density polyethylene (48%) comprised highest proportion plastics, followed by low-density (22%), terephthalate (13%), polypropylene (10%), and polystyrene (7%). In second stage, were...
This study investigates the treatment of cutting oil wastewater from automotive parts manufacturing industry to promote sustainability via use 'used shot blasts', which are by-products auto production. Used blasts rich iron sources Fe0, becomes an effective catalyst in Fenton reaction. A modified air-Fenton (MAF) system was proposed generate hydroxyl radicals that eliminated recalcitrant organics wastewater. First, Taguchi method, comprising L18 orthogonal array design, used identify...
The objective of this research is to manage waste glass in Koh Sichang, Chonburi province, used as a partial fine aggregate replacement concrete brick production.An experimental approach aimed determine the level for optimal compressive strength.Five samples 0, 10, 20, 30, and 100% aggregates by weight were tested at 7, 14, 28 days.The microstructure mineralogical phases bricks investigated scanning electron microscopy X-ray diffractometry, respectively.The results showed that strength was...
Abstract Reused wastewater is commonly treated with disinfection to remove pathogenic microorganisms; however, this process generates byproducts (DBPs), such as trihalomethanes (THMs). This study aimed investigate the levels of THMs and THM formation potential (THMFP) in originating from different sources i.e., domestic, food-processing industry hospital. The samples each source were collected three times between June August 2023. Dissolved organic carbon (DOC) was evaluated prior after...
The formation of haloacetic acids (HAAs) from the chlorination individual and binary mixtures organic fractions obtained intake Bangkhen Water Treatment Plant in Bangkok, Thailand was investigated. Experimental results revealed that, as an fraction, hydrophobic base (HPOB) most active forming HAAs (approx. 200 microg/mg) whereas hydrophilic acid (HPIA) least 40 microg/mg). In mixtures, exhibited stronger inhibitory effect than fractions. With set experimental data this work, no relationships...
The fractionation of raw water from Bangkhen treatment plant, Bangkok, Thailand revealed that the mass distribution sequence six organic fractions high to low was hydrophilic neutral (HPIN), hydrophobic acid (HPOA), acid, neutral, base, and base. main matter components in were HPIN HPOA, which also two most important contributors trihalomethane formation potential (THMFP). Linear dependencies between level each fraction THM species observed, suggested reactions chlorine during chlorination...
