Meniscus Real Time Calculation API Released

We have released the Meniscus Calculation Engine RESTful API on our own Meniscus Support area – click here – and also on the ProgrammableWeb site – click here. We will be increasing our support for this API over the coming months.

Denitrification

Environmental concerns about the release of greenhouse gases to the atmosphere, and issues of global warming and climatic change regularly feature in the media. What is often not referred to in these stories is the role of wastewater treatment. Biological processes could have a major effect on the composition of the atmosphere. Recent studies reveal […]

Domestic Energy Use Oil vs Electricity

Using our Real Time Energy dashboard to work out overall energy used for hot water, central heating and cooking (using an AGA) as well as comparing the cost of hot water using cheap Economy 7 night time electricity for heating water versus oil.

Nitrification and Denitrification

Sewage is made up of carbonaceous waste and a small amount of nitrogen waste. Nitrogen is a found in proteins and in ammonia, an important compound in sewage.

Bulking In The Activated Sludge Process

Bulking can be said to have occurred in activated sludge plants when the sludge does not settle easily and has an excessive volume. This can lead to carry over from the final effluent clarifies.

Anaerobic Digester Performance

A question often posed by operators of anaerobic digesters is “what should I be looking for?”. This is often in the context of process plant with a myriad of expensive instrumentation and computer control.

What is the FM Ratio

One of the most fundamental control parameters for the activated sludge process is the relationship between the load (i.e. kg/day as opposed to mg/l) of BOD (or bacterial ‘food’) entering the aeration plant, and the ‘mass’ of bacteria in the aeration tank available to treat the incoming BOD.
