Filling machines for water treatment chemicals
Coagulants, flocculants, hypochlorite, pH correctors, antiscalants and biocides — filled in drums and IBCs (totes), in bulk, day after day, into containers that go straight to a treatment plant.
KEMIRA, SOLENIS and VEOLIA all fill on AiCROV machines.
This is a sector where the product is corrosive, the margin is thin and the container is almost always the same: a drum or a 1,000-litre (275 gal) IBC on a pallet. The machine has to be built for exactly that.
Concentration changes the density. It does not change the weight.
This is the argument that matters most here, and it is specific to this sector.
You do not sell one ferric chloride. You sell it at several concentrations, and each one has a different density. The same is true of hypochlorite, of caustic soda and of most of what goes out of a water treatment plant’s supplier.
A volumetric machine has to be recalibrated for every grade. Litres are not kilos, and the conversion changes with every concentration, and again with temperature. Get it wrong and you are either giving product away on every container or shipping short.
A scale does not care. Every AiCROV machine fills by weight. One machine, every concentration, no conversion table to maintain and no recalibration when you switch grade. The recipe holds the target weight and the filling parameters, and that is the whole of it.
Built around the IBC
Most industries fill a mix of formats. This one fills drums and IBCs, and that changes what the machine has to be good at.
Our machines fill on the pallet: the container arrives, is filled where it stands and leaves, with no transfer and no manual handling of a full 1,000-litre container. The SP1, SP2, SP25, SP3 and Robot Filler all handle drums and IBCs on the pallet, which means the same line can take a 200-litre (55 gal) drum and a 1,000-litre IBC without reconfiguration — only a recipe change.
At the volumes this sector moves, that is where the hours are won or lost.
Corrosive is the normal case here, not the exception
Ferric chloride, polyaluminium chloride, sodium hypochlorite, caustic soda, sulphuric acid for pH correction. In this group, aggressive chemistry is not a special order — it is the product range.
The wetted parts are specified for what you actually fill: titanium, Hastelloy, PTFE, PVDF, PVC, or a combination, with the structure staying in stainless steel. More than eighty nozzle combinations, and the choice is made with your data sheet in front of us, not from the name of the product. See acids, bases and aggressive products for how that selection is made.
Hypochlorite deserves its own mention: it degrades on its own, it gives off gas as it does, and it attacks materials that hold up to other chemicals perfectly well. Gas hood and fume extraction over the filling point and overfill detection are the options that matter most in this group.
Polymers, and why anti-drip is a safety feature
Flocculant polymers are among the most awkward products we fill. They are viscous, they string, and a few drops on the floor become a slip hazard that does not evaporate and does not mop up easily.
Anti-drip nozzle with positive closing, a closing profile matched to the viscosity, and the nozzle held in position long enough for the product to break cleanly. On a polymer line, keeping the product off the floor is not tidiness — it is the difference between a walkable aisle and an incident report.
Automation, for the same reason as everywhere else in this sector
With ferric chloride or hypochlorite, the strongest argument for automating a line is not the output. It is that the operator is not standing next to the filling point while it runs.
On a semi-automatic machine the operator is at the container for every fill. On an automatic line the pallet goes in, the machine works behind a guarded enclosure, and the operator is somewhere else. If you are weighing two machines and one of them removes a person from that area, that is the reason to choose it.
Containers
- IBCs and totes, up to 1,500 litres (400 gal), the format of this sector
- Drums and barrels, steel and plastic, 200 and 208 litres
- Jerrycans and canisters, for biocides, antiscalants and concentrated dosing products
Which machine fits your line
Any AiCROV machine can fill these products. What decides which one you need is not what you fill — it is how many containers per hour you have to produce, in what format, and how much of the operation you want automated. Every container format, from a one-litre canister to a 1,500-litre IBC, has machines across the whole range, from semi-automatic to fully automatic.
What the product decides is everything inside the filling unit: whether it is filled by immersion or under the bunghole, the materials in contact with it, and how the nozzle itself is driven — push or pull, two-stage coarse and fine opening or proportional, and whether the process needs flow control and continuous pressure.
That is why our first step is a conversation and not a quotation. Tell us your output, your containers and your product, and the configuration follows.
LSG — semi-automatic weigh filling machine for jerrycans and small containers
Semi-automatic weigh filling machine for jerrycans and small containers. No installation: connect power, air and product, and it is ready to fill.
LSB — semi-automatic weigh filling machine for drums
Semi-automatic drum filling machine for 30 to 250 litres: it weighs every drum as it fills, comes preconfigured and is simple to run.
LSC — semi-automatic weigh filling machine for IBCs
For plants that only fill IBCs (totes): quick to set up and configure, and available in an explosion proof version.
SP1 — semi-automatic weigh filling machine for containers on a pallet
Semi-automatic weigh filling of jerrycans, drums and IBCs on a pallet: the operator positions the nozzle and the machine fills to the net weight.
SP2 — semi-automatic filling line for containers on a pallet, with conveyors
Semi-automatic filling of drums and IBCs on a pallet, from 20 to 1,500 litres, by weight, on a preconfigured machine.

SP3 — automatic filling machine for drums and IBCs on a pallet
With the Robot Filler, this is the most automated machine we build. The operator does not intervene during the cycle…
Robot Filler — fully automatic robotic filling machine for drums and IBCs
Robotic filling of jerrycans, drums and IBCs on a pallet: 3D vision finds each container, then the robot uncaps, fills, caps and seals.

EL2-E — in-line automatic filling machine for jerrycans and small containers
Automatic in-line weigh filling machine for liquid and viscous products in metal or plastic canisters, pails and jerrycans with a rectangular base.
Frequently Asked Questions
Do I need a different machine for each concentration?
No. We fill by weight, so the density of the grade is irrelevant — there is no conversion and no recalibration when you change concentration. A volumetric machine would need both.
Can it fill IBCs on the pallet?
Yes. The container is filled where it stands, with no transfer and no manual handling of a full IBC. The same line takes drums and IBCs with a recipe change.
What material do you use for ferric chloride?
It depends on concentration and temperature, and the answer is not the same as for hypochlorite or for sulphuric acid. Send us the data sheet and we will tell you what we would fit and why.
Can you fill sodium hypochlorite?
Yes, with the wetted parts specified for it and with gas hood and fume extraction over the filling point, because it gives off gas as it degrades.
How do you stop polymer dripping onto the floor?
Anti-drip nozzle with positive closing and a closing profile matched to the viscosity. On a polymer line that is a safety measure, not a cosmetic one.
Can the operator stay out of the filling area?
Yes, on automatic machines, and with the products in this group that is usually the strongest reason to choose one.
