Zero-Smell fermentation tank with chemical-free deodorization

Deodorization Study of the Swine Manure with Two Yeast Strains 137 2.5. Odor components extraction and quantification Using the modified procedure of Ohta and Ikeda [24], utilized by Govere et al. and Ye et al. [18,19], 20 g aliquots of swine manure sample was

Stage 1: Optimal aeration and water control lead to high oxygen absorption, generating high temperatures in the compost heap.Degradable volatile solids decrease, odor diminishes, and the compost’s color gradually changes. Stage 2: Temperatures decrease, the oxygen absorption rate slows down, and the odor completely disappears.

2022/2/1/ · Anaerobic digestion (AD) technology converts various organic substrates to methane and is widely used in waste treatment and clean energy production [1]; however, increased output of biogas slurry (BS) is an inevitable outcome of AD, which is a leading cause of environmental pollution and poses risks to human health, particularly via water eutrophication,

Aquilair chemical deodorization towers (acid or oxidizing) are generally very effective on conventional pollutants (H 2 S, NH 3, mercaptans and amines). However, the reaction time is too short to treat volatile organic compounds (VOCs) which are typically generated during thermal conditioning of sludge, for example.

2.2 Chemical method Chemical deodorization method mainly includes chemical absorption, chemical oxidation and masking agent method and so on. Chemical absorption is a method that uses NaOH, NaClO and H 2 SO 4, etc. to react with the odor 3 2

2023/5/4/ · Common Types of Fermentation TanksFermentation tanks come in a variety of forms, each suited to different purposes. Here are some of the most common: Cylindroconical Tanks: Widely used in breweries, these tanks feature a cone-shaped bottom to collect yeast and sediment efficiently.

2018/10/15/ · The seaweed B. fusco-purpurea was taken as an example to investigate the chemical transformation pathways for the deodorization process with S. cerevisiae fermentation. Sensory evaluation, GC–MS, GC–MS–O and odor activity value (OAV) analyses showed the fishy odorants were 1-octen-3-ol, ( E )-2-nonenal, 2,4-decadienal, 2-pentylfuran, 2-octen-1-ol and

2023/4/1/ · The global demand for algae-derived products is following consumer preferences for healthy, nutritious, and vegan products. Batch, semi-continuous and continuous deodorizers used in industry

2024/6/30/ · Unlike chemical techniques that reduce fishy odor by impeding lipid oxidation via the use of reactants and catalysts, physical techniques focus on masking fishy odor by either covering it with a pleasant aroma or adsorbing fishy substances (Table 4, Fig. 2 B).

Basic theory and principles of degumming, refining, bleaching, and deodorization are reviewed. Composition of crude oils, hydration of ions and molecules, neutralization of organic acid, and separation and modification of products by centrifugation, adsorption, and vacuum steam distillation are briefly summarized. Reactions of vegetable oils include hydration, neutralization,

In this study, an aerobic composting device was designed to consider segmented fermentation for composting material, precise aeration and turning control, and multi-function integration.

2021/10/5/ · The recycling of high-density polyethylene plastic (HDPE) plays a crucial role in sustainable development. EDX analysis showed the atomic percentage of each element in HDPE Natural plastic flake

Deodorizing Process Parameters Temperature • Temperature range : 150 C – 270 C • Depending on type of oil and targeted effect - Heat sensitive oils (cocoa butter, fish oil) : 150 C-190 C - For FFA stripping and/or heat bleaching : 240 C-260 C • Trend to reduce ‘heat load’ during deodorization
