Reedbed Filtration together with Chemical Treatments

I have had the great pleasure to develop with Tony Lumb, a number of industrial applications for Reedbeds, where Reedbeds or Chemical Treatment alone do not solve the problems. You can contact Tony through his Company’s web pages:   I would trust Tony with my money!

When added together, Reedbed Filtration and Chemical Waste Water Treatments make possible the most amazing water quality.  Tony knows all there is to know about standard waste water chemistry and industrial chemical treatments.

Bio Fumes Filtration
Reductions of up to 95% of Ammonia, NOx, Sulphur Dioxide, Carbon Dioxide, Fumes.

Melvyn Rutter introduces a new low cost, long life, high quality solution to the problems of efficient elimination of fumes and noxious smells.

The standard route for the treatment of industrial fumes is usually to use a fume scrubber – a tower which sprays a chemical solution counter current to the air flow. It relies on electrically driven pumps and fans, plus a supply of chemicals which have to be disposed of when spent. These scrubbers represent a large initial capital cost and have high ongoing maintenance costs – in terms of electricity, chemicals and disposal.

How does the process work?
It uses Melvyn Rutter Reedbed technology and works on the incredibly simple basis that bacteria will eat anything – they just need to be kept in a bed that doesn't dry out – nice and warm and damp – and they’ll enlist. You just add an inoculum (big dose of bacteria) and there you go. And after that it requires minimal maintenance.

Plus they don’t take up huge amounts of space because the systems we provide are vertical flow, aerobic, solid soil, modulated systems.

Our solution:
• is cost effective in terms of both capital and running costs
• is environmentally sustainable – a factor which is becoming increasingly important across the industry
• and requires minimal maintenance.
• And we can demonstrate it in our mobile demonstration unit.

We have run trials with every system, establishing the flowrates, and therefore understanding the size of the full scale system required.

We trialed compost beds at a carpet factory in Bacup, Lancashire. In feeding the ammonia rich air through the compost beds, the factory air was fresh with no fumes, and the surrounding district had clear air, too.

Reductions were in the order of 85%, once we finally worked out the dimensions.  Unfortunately, the factory was burnt down, leaving only the compost bed standing. This brought a very sad end to a promising project.

NOx air pollution is a major urban problem. This method of filtration could significantly reduce street level pollution. We no longer need to talk about these problems, we can begin to solve them.

The carpet company requires only 150m2 Compost bed system. This system would run with low levels of maintenance for perhaps 20 years.

The Lias Clay Company in The Czech Republic has a plume that heads towards Karlov Vary, where the Russian Millionaires holiday. The computer readout showed 99% reductions of Carbon Dioxide and Sulphur Dioxide concentrations.

Interestingly, the best, and most enduring ideas around are usually the result of someone looking at a problem from an unusual perspective, and applying a huge dose of good old common sense. Well, in principle that’s what we've done. Yes, there are already applications to deal with noxious fumes out there. But that’s all old hat, expensive and cumbersome. Talk to us.

We’re ready to talk to you. One engineer said if this system worked, he would eat hay with a donkey, so we provided both the hay and the donkey.

Sludge De-Watering
We conducted an experiment to see how to effectively de-water sludges.

The sludge came from Northumbrian Water, from their drinking water treatment.

We were in communication with Debbie from Nature’s World in Middlesbrough. She is tasked with finding uses for glass shards, which come from recycling glass bottles. The glass can be crushed down to a variety of sizes, although there is plenty of dust, the shards are similar to sand. Although it could be argued that the glass is a more uniform size and not full of dust from unknown sources and qualities.

The method was to half fill an IBC tub with both gravels and glass shards. This was to act as a pre-filter to the reedbed. A delivery bag sat on top of the glass gravel filter for the collection and de-watering process.

The reedbed tub (seen in blue) was a nominal size to show the principle. The correct size for a particular flow would need to be established for a full sized system.

De-watering could take up to 14 days. It is entirely possible for there to be a number of tubs, filled in sequence, all feeding into the one reedbed. A 20m2 reedbed could filter between 1000 and 1500 litres per day, depending on concentrations.

Of course the glass and gravels can be washed and re-used. There may have to be materials replaced from time to time.

Further sludge de-watering is taking place, this time with mine water lagoon sludges. All results and data will be posted once we have them. However, the de-watered cake we have produced is so very similar to sludge from the chemical and centrifuge processes. As solid wastes these can now be disposed of easily. Therefore this method has a very wide application throughout industry.

"It costs nothing to call to have a chat about waste water problems. Between us we should be able to find solutions, and save a few bob in the process. No heavy sales pitch. I always leave you with time to consider your options.
