Summary
Phosphorus Recovery by Crystallisation (P-RoC) technology successfully recovered phosphorus from sewage in a pilot study. The technology proved practical, yielding valuable phosphate products from wastewater.
Area of Science:
- Environmental Engineering
- Chemical Engineering
- Water Treatment Technologies
Background:
- Phosphorus is a critical nutrient, but its release into waterways causes eutrophication.
- Wastewater contains significant amounts of phosphorus that can be recovered.
- Innovative technologies are needed for efficient phosphorus recovery from waste streams.
Purpose of the Study:
- To evaluate the practicability of a pilot-scale Phosphorus Recovery by Crystallisation (P-RoC) plant.
- To investigate the quality of phosphate products generated using P-RoC technology.
- To assess phosphorus recovery from actual sewage.
Main Methods:
- Pilot-scale testing of the P-RoC technology.
- Analysis of wastewater influent and effluent for phosphorus content.
- Characterization of the crystallized phosphate mineral phases.
Main Results:
- The P-RoC pilot plant demonstrated successful phosphorus recovery from real sewage.
- The technology proved to be practicable for on-site application.
- The generated phosphate products were investigated for their quality and potential applications.
Conclusions:
- P-RoC technology is a viable method for phosphorus recovery from sewage.
- The pilot study confirmed the practicability and effectiveness of the P-RoC system.
- The recovered phosphate products meet quality standards for potential reuse.

01:27Upstream Processing
Upstream processing represents a critical phase in biomanufacturing, wherein biological systems such as microorganisms, mammalian cells, or insect cells are cultivated to produce therapeutic proteins, vaccines, enzymes, or other biologically derived products. This phase encompasses all steps from the selection and genetic manipulation of the production organism to the cultivation of cells in bioreactors under tightly controlled environmental conditions.Host Selection and Genetic OptimizationThe...
01:29Downstream Processing
Downstream processing begins once fermentation is complete and involves a series of steps to recover and purify products such as acids, vitamins, antibiotics, or proteins.Cell HarvestingFor example, for intracellular protein-based products, the first step is harvesting the cells. This is typically achieved using centrifugation or filtration to separate the cells from the liquid phase.Cell Disruption for Intracellular ProductsIf the target product is intracellular, the harvested cells must be...
01:14Scale-Up Processes
The scale-up of microbial fermentation processes is essential in industrial biotechnology, allowing the transition from laboratory-scale experiments to commercial-scale production while aiming to maintain product yield and quality. This process requires meticulous adjustment of equipment design, process parameters, and contamination control strategies to accommodate increasing culture volumes.At the laboratory scale, cultures are typically maintained in 1 to 10-liter glass or autoclavable...
01:30Biological Treatment of Effluent and Waste Water
Biological wastewater treatment relies on the metabolic activity of microorganisms to remove pollutants from sewage. In modern treatment systems, this process is organized into sequential stages that progressively reduce solid material, dissolved organic matter, and microbial contamination. Each stage plays a distinct role in improving water quality and preparing the effluent for safe discharge or reuse.Primary and Secondary TreatmentPrimary treatment is a physical process that removes large...
01:27Production of Alcohol
Continuous fermentation is a key strategy in industrial ethanol production, particularly when efficiency, scalability, and high yields are essential. This approach allows for uninterrupted operation and optimized resource utilization. The primary feedstock, corn starch, undergoes enzymatic hydrolysis facilitated by α-amylase and glucoamylase. These enzymes break down the starch into fermentable sugars such as glucose, which are readily assimilated by fermentative microorganisms.Fermentation...

Polyethylene terephthalate (PET) is a synthetic polymer widely utilized in the packaging industry, particularly for bottles and containers. Due to its chemical stability and durability, PET accumulates in the environment, contributing significantly to plastic pollution. It comprises repeating units of terephthalic acid and ethylene glycol, resulting in a semi-crystalline structure that is resistant to natural degradation processes.A notable breakthrough in plastic biodegradation came with the...
