Why is the pH Important?
The correct mix of feedstock such as slurry, food waste and processed plant material is important to ensure efficient biomethane production.
This combined feedstock (media) is broken down by microorganisms in a series of steps, resulting in the production of methane (methanogenesis).
The pH of the media is an important consideration during this process. Values...
Anaerobic Digestion (AD) is the process of microbial breakdown of biomass to produce a viable source of methane-rich biogas. The resulting methane gas can then be used as fuel in transport, heating, or the generation of electricity. The biomass source commonly used in the UKÂ is wastewater sludge, due to its high availability.
In this industry, regulations and ongoing monitoring play an import...
Whilst most commonly associated with the monitoring of biochemical oxygen demand (BOD), the OxiTop system can be used for many types of respirometric testing including OECD biodegradability tests, soil respiration and biogas testing. The classical OxiTop heads have been around for many years and are tried and tested. This year, they have been modernised with two new groups of heads being releas...
The FOS/TAC ratio is a commonly used indicator for assessing the fermentation process within biogas reactors, where FOS is a measure of the volatile organic acids (measured in mg CH3COOH/l) and is TAC is a measure of the total inorganic carbon i.e. the alkaline buffer capacity of the system (measured in mg CaCO3/l). In simple terms, this ratio looks at acid vs alkaline in the system which helps...
Thanks for sharing such a great information.. It really helpful to me.. I always search to read the quality content and finally i found this in you post. keep it up!
I came across your article about "DPD Tablets" on Camlab Info, and it's a valuable resource for anyone seeking information about water testing and analysis using DPD tablets. Your explanation of their usage and significance in water quality monitoring is quite informative.
This article on nanocolor tube tests is a gem for analytical enthusiasts. The idea of zero calibration is intriguing, and your detailed explanation makes it accessible. The step-by-step process helps demystify the technique for beginners like me. The use cases you've highlighted, particularly in...
Grant have introduced the new Controlled Rate Freeze Thaw (CRFT), which is a liquid nitrogen and cryogen free controlled rate freeze and thaw system for cryopreservation in a wide range of applications. Cryopreservation is a process where biological materials such as cells, tissues...
A dipslide is a means of testing the microbial content of liquids. This is a common method of monitoring and measuring microbial activity within many systems and commonly cooling systems. Usually the use of a dipslide is the first line of defence for the testing of microbial issues that could be...
Purchasing items using donated funds without the burden of VAT will now save many Millions of pounds each year which can be put to better use in advancing scientific knowledge to provide new treatments and cures that will shape the medicines of the future.
Working with pressure/vacuum conditions in the lab is common but not all products are designed to withstand this. Products with appropriate geometry and wall thickness are suitable for working safely with pressure. For example, filtering flasks, desiccators, or flat flange vessels, as well as...
