It’s basically the carbon you’re taking out via the methane.Perhaps I’m wrong but i was of the opinion that digestate, although highly variable depending on whats feeding it, is high in p and k not so much nitrogen

And the N etc in the liquid?That is exactly what happens at the sewage treatment plant, where the solids are separated and used as fertilizer. The treatment is to kill pathogens in the solids, the liquid is treated by varying methods and returned to the water course.
Yes, the N follows the liquid, and is affected by what type of separation is used (screw press on centrifuge).And the N etc in the liquid?

The centrifuge will take out much more liquid - at a price.

It should also be regulated that all the by-product should be returned to whence it came - the land/soil on a pro-rata basis.
A friend of mine works in a water treatment facility, after hearing what they use to ‘treat’ the water would put you off it for life!That is exactly what happens at the sewage treatment plant, where the solids are separated and used as fertilizer.

Well its all about correcting the ph apparently, if its high you need to lower it with acid, battery acid is the go to product. He was saying it actually comes in barrels marked as battery acid.What ?
Thank you. Less than I recollected. No idea how I would be able to work on that!1180 calories for an adult in France in WW2

And the more houses they build the greater the problem becomes! Governments are very keen on building houses, not so keen on admitting the problem it causes.Spot on. That's really what we should be looking for and is true recycling.
However, the real problem IMHO is the fact that rainwater falling on people's houses immediately gets mixed with foul water in the sewerage system. Something I doubt the government has the stomach for to fix - because this causes overflow problems at sewerage works.
They use floculants and coagulants, this explains it fairly well.A friend of mine works in a water treatment facility, after hearing what they use to ‘treat’ the water would put you off it for life!
They use floculants and coagulants, this explains it fairly well.
On the diagram, where is says "secondary treatment" it is after that, that sludge becomes fit to be used as a fertilizer.
How are coagulants and flocculants used in water and wastewater treatment?
Coagulation and flocculation are essential components of both drinking water treatment and wastewater treatment.www.wcs-group.co.uk
We need food and energy but we don't have to use arable ground to produce energy, be that AD plants or plonking solar panels on it. Burning thousands of tons of wood chip every day instead of just building a nuclear plant is just as daft in my opinion.Or, we are using perfectly good land that could be used to grow feed-stock to produce energy, we need both food and energy, we can't survive without either of them.
AD is the only flexible renewable that re-cycles all the nutrient AND produces base load energy. No other source of renewable energy comes anywhere close on efficiency.
...and for the umpteenth time:
Feed-in Tariffs: guidance on sustainability criteria and feedstock restrictions
This guidance is for applicants of AD installations that are seeking accreditation under the FIT scheme from 1 May 2017.www.ofgem.gov.uk
As many know, Germany (and France) has 000's of AD Plants, and this debate is a non-event.
In m3 per ton/£ of CH4/ha, nothing can compete with Maize, hence it's the crop of choice.
However, we must do much more with waste, which should be legislated that it must go to AD.
The AD plants should be designed and located where the gas can be upgraded and injected into the gas grid, and any surplus heat utilised on-site.
It should also be regulated that all the by-product should be returned to whence it came - the land/soil on a pro-rata basis.
In the UK we were faced with a major challenge. Much of our dated energy production plants were coming to the end of their life, and little in the pipeline to replace them.We need food and energy but we don't have to use arable ground to produce energy, be that AD plants or plonking solar panels on it. Burning thousands of tons of wood chip every day instead of just building a nuclear plant is just as daft in my opinion.
Until we can produce food in some other way that doesn't involve land, prime arable land should really be used for food.
AD plants should be run on waste only.
Are you involved in an AD plant?
