The feasibility of using planted biofilters for purification recirculated aquaculture water in the Mekong Delta Vietnam was assessed. plant trenches were able to clean tilapia and maintain good quality fish tanks without renewal water. NH4-N removed efficiently trenches, particularly with Canna glauca L., probably because uptake nitrification–denitrification. Plant constituted 6% N 7% P input feed. Approximately 1.0 m3 needed per kg produced, 370, 97 2842 g fresh aboveground biomass Ipomoea...
In recirculating aquaculture and hydroponics systems, the waste products from fish production are used to produce vegetables or other crops of economic value, water is recirculated tanks. We studied growth, productivity nutrient uptake four leaf vegetable species (Lactuca sativa, Ipomoea aquatica, Brassica rapa var. chinensis parachinensis) in a controlled growth experiment with three root flooding treatments (drained, half-flooded flooded) assess their preferred hydroponic requirements,...
Abstract Water quality is a critical challenge in Asia the context of growing industrialization, urbanization, and climate change. Nature‐based solutions (NbS) could play an important role reducing urban water pollution, while generating multiple co‐benefits that make cities more liveable resilient. In this regard, number pilot demonstration projects have been set up to explore their potential across Asia. Their effectiveness impacts, however, not adequately documented, thus how they can be...
The study aimed to evaluate the management and treatment status of derived wastes from whiteleg shrimp culture ponds in Soc Trang, Bac Lieu Ca Mau provinces. Thirty small-scale farming households each studied location were randomly selected for a questionnaire-based survey. There was an average 35.7% used chlorine treat wastewater at end seasons. number treating prior discharging into environment 8/30 4/30 as many 10/30 Mau. remaining discharged directly untreated-water environment....
The rapid development of whiteleg shrimp farming in the Mekong delta Vietnam has an adverse impact on environment due to large amount nitrogen and phosphorus content wastewater pond sludge/sediment. Phytoremediation is a promising technique use plant for mitigating environmental impacts from intensively culture. Growth responses, removal Typha orientalis Scirpus littoralis were assessed at three water levels +15 cm, +30 cm +45 cm. They arranged completely randomized design with replications....
Scirpus littoralis Schrab and Typha orientalis C. Presl are cultivated in the paddy field shrimp pond Mekong Delta of Viet Nam for human food providing habitat shrimp, respectively. They recognized as phytoremediator brackish aquaculture wastewater treatment system. However, information on effects NaCl plant growth mineral concentrations two species is limited. Therefore, present study was carried out to identify salt-tolerance between species. Six salinity (0, 5, 10, 15, 20, 30 ‰) were...
The aim of the study was to identify key factors water environmental parameters affect shrimp productivities in mixed mangrove-shrimp system using multivariate approach. Water quality assessment conducted at four mangroves stand ages (MAs) 2–4, 5–7, 9–12 and >12 years old, with two level (WLs) regimes ponds 0–20 cm 20–40 cm, every interval 15-day grow-out cycle systems based on moon. farms within appropriate range for growth. Mangrove affected alkalinity, pH, COD, N-NO2, N-NO3 H2S, but did...
This study was conducted to evaluate effects of three different surface areas constructed wetlands as 1.77; 0.78 and 0.41 m2 on water quality in intensive closed-recirculation whiteleg shrimp (Litopenaeus vannamei) culture tanks. Each wetland system arranged serial connection vertical subsurface flow horizontal systems. Canna sp. is grown at a density 10 plants/m2 the The carried out for 70 days. results showed that larger area better obtained. Although exchange did not required entire...
Hymenachne aquatic grass, acutigluma was planted in the wastewater from intensive striped catfish (Pangasianodon hypophthalmus) cultivating ponds containing 2.1 mg N/L, which enriched with a serious of inorganic phosphorus concentrations. The experiment arranged completely randomized design three replications net house for 42 days. results showed that P concentrations did not significantly affect growth Hymenachne. presence high resulted increase content plant tissues leading to higher...
The study was conducted in the net house to evaluate salt tolerance capacity of Para grass, Paspalum grass and Setaria which were grown hydroponics condition with Hoagland solution. NaCl added get five levels 0, 5, 10, 15 20‰, a weekly increment 5‰ into solution until reached level 20‰. experiment arranged completely randomized design three replications. results showed that 15‰ 20‰ affected growth studied species, but did not affect survival rate grass. Chlorophyll content (SPAD unit)...
Calcination is one of the effectively thermal pretreatment methods to enhance phosphorus adsorbability cockle shells. The objective study evaluate effect three treatments 550, 750 and 950°C on P-adsorption capacity cockle-shell powder (d≤2,0 mm). Process adsorption was conducted in laboratory condition for 24 h with PO43- concentration 20 mg/L. results showed that powders heated at temperature >750°C had higher adsorbability. P removal efficiency treatment 99.2%. In other words, 1 g could...
The study was conducted to evaluate the effects of five NH4-N:NO3-N ratios (in mol) 4:0, 3:1, 1:1, 1:3, and 0:4 on growth Hymenachne acutigluma. experiment arranged in a completely randomized design with 12 replications for each treatment. H. acutigluma water quality were determined every 2 weeks 8 weeks. results showed that dry weight high ratio 1:3 0:4. presence increment both nitrogenous forms NH4-N NO3-N catfish wastewater helped enhance content uptake capacity inthe shoots roots...
The objective of this study was to determine the effects plant density on growth and uptake nitrogen phosphorus which were added in wastewater from intensive catfish Hymenachne grass (Hymenachne acutigluma). There four densities 10, 20, 30, 40 shoots/m2 control treatment (without plant). experiment arranged completely randomized design with twelve replications. H. acutigluma water quality evaluated every two weeks for eight weeks. Harvested dry biomass planted at higher than that 10...
The study was conducted to monitor the real-time status of toxic compounds P. monodon in intensive recirculating aquaculture system integrated constructed wetlands (CWs) designed with surface flow (SF), vertical subsurface (VF) and horizontal (HF), examine removal efficiency contaminants different CWs. Plants used were cattail (Typha sp.), elephant grass (Pennisetum purpureum) unplanted systems as referenced samples. Recirculating rate per day 50 % total water volume tanks. Water from...
The study is aimed to assess the implementation of regulations on current supply status rural domestic water, water quality and users’ opinions as baseline data improve activity in Tien Giang province. This was carried out by collecting secondary zones 30 stations from 3 groups enterprise, state-run community 2010 2014, well direct interviewing officers households each group. results showed that followed guidelines Circular 15/2006/TT-BYT issued Ministry Health.
