hi all, does anyone use one of those seperator tanks when vacuuming from a rotary washer, are they worth having and could you make one up yourself? if you have one could you take a piccie of the inside of it to give us an idea?  Also, has anyone modified their fsc to vacuum out, I have and it works very well?

there must be someone here with experience using these lots of guys use them?

I am having one fabricated at the moment but don't have any pictures

I'm thinking of adapting a drum but want to better understand how solids drop into the tank and water continues into the vac for pump out. I've adapted a big stainless numatic to accept water and put in a big submersible dirty water pump with a valve etc.

How will yours be set up, i.e. will it have the in and out hose next to eachother through the top or will you have one on top and one on the side, does this make a difference to how water travels?

Sorry trying to book accommodation for works in London

It is a 500 litre tank with 3 separate chambers, they are separated by three internal walls, these are lower than the height of the tank ceiling, allowing water to flow over the top of them, settle and then move onto the next chamber. Does that make sense?

Rob, wouldn't 3 walls be 4 chambers?

Walls - Balls

I do mean balls to walls - bad day today. I think it is two internal walls give three compartments

Funnily enough I have put a second tank (400) in my Iveco today and this has the same principle - never noticed it before, had it five years.

hi rob,

your tank sounds like a sediment tank whereby dirty water enters one side then moves of the tops of walls with the heavy solids not making it over the tops so they accumulate at the bottom for collection later. Is this part of your filtration system? How many litres per min can this system deal with and do you polish the water off afterwards for reuse?

I was actually referring to something like this ISSA separator tank http://www.hfmcleaning.co.uk/products/issa_separator_tank_on_wheeled_trolley-wet_dry.html .

Yes it is a sediment tank. It will handle 60LPM but the main recovered solids will be caught by a pre filter (sock or other)

How will you empty out the sediment?

[Rob_Mac]

The sock filter will take care of a large proportion of the suspended solids and then I am expiating a monthly clean out of anything else.

Rob,
Hows the setup going curious you mention pre filter socks .. any idea of microns or physical size you are looking at ..... before 'sediment' tank, I am considering adding some form of bio filter you mentioned a monthly clean out ... one day in hot sun and the water / waste smells a little ... how shall we say 'Rare'  fortunately we dont see much sun 

[mick mac]

some ideas from these videos may help you.

yeah I've seen this one before however I get the principle of how the tanks are used, i.e. the solids / liquids drop into the separator tank before entering the final vacuum therefore in theory you could use a dry only vac to suck up liquids, however, I've also seen these used whereby only the heavy solids get trapped in the tank and the liquids getting carried over via sucktion into the vacuum with pump out. This is what I want to achieve, I guess the design of the inlet / outlet tubes into the tank will dictate if the liquid carries over.. Does anyone have any ideas??
