Liquid concentrate, cold-weather blend
SediLogic Liquid Cold
The base liquid's job, in a blend selected to keep working as the water cools. A concentrate for installations that physically cannot take a solid and that also run cold enough that a standard blend would slow — the same digestion of organic material, carried by strains chosen for low temperatures.
01Why this format
Organic load where a solid cannot be dosed and the water runs cold
This answers two constraints at once — a system that can only take a liquid, and water cold enough that a standard blend sits idle — and, like the base liquid, it is a constraint-answer rather than an upgrade. Biological activity falls away as water cools; this blend is selected to keep going further down the range. Where a solid can be dosed, or the water is not actually cold, the standard formats put more product where it is needed for the same money. It is not part of the launch range, and it is shown here for the narrower case the base liquid does not cover.
It works in the metered or poured, as the installation allows, and it suits liquid-only systems working through cold conditions.
02Specifications
What is confirmed, and what is not.
Every figure below comes from a manufacturer document or an exact-SKU private-label source. Where the supplied documents publish no value, the table says so. Nothing is estimated to fill a gap — a placeholder specification that later moves is worse than an admitted blank, because a buyer may have planned around it.
- Pack size
- 5 gal pail
- Pack price
- $515Indicative. A distributor list price, not a manufacturer specification — landed cost and freight are not yet confirmed, so the figure you are quoted may differ.
- Dose rate
- Not publishedA revision-controlled liquid dose method for quotation is not present in the supplied documents.
- Storage
- Store in a cool, dry place, away from direct sunlight; keep the container closed.
- Safety Data Sheet
- Not publishedNo product SDS was found in the supplied source folder. An OSHA HazCom / GHS SDS is still required before ordering.
- Technical Data Sheet
- Manufacturer product specification sheet available
- Product label

03When not to buy this
Three situations where this product is the wrong answer.
- A solid form can be dosed at all. A dense solid puts organisms at the blanket where the material sits; any liquid, cold-weather or not, disperses through the water column instead.
- The water is not genuinely cold. The cold-weather blend earns its place only where low temperatures would stall a standard product; in warmer water the base liquid does the same work for less.
- The target is an accumulated benthic sludge blanket. A liquid introduced at the surface disperses through the column rather than concentrating on the blanket, which is the whole reason the sinking solid exists.
The dosing planner screens for all three and will say so rather than routing you to a quotation.
04Microbiology
What the organisms actually do to the material.
The mechanism is enzymatic hydrolysis. Bacillus species secrete enzymes into their surroundings that break large organic molecules into fragments small enough to be taken up and metabolised. The organisms are not consuming sludge directly; they are releasing the tools that take it apart.
| Enzyme | Acts on | What that is, in a lagoon |
|---|---|---|
| Protease | Proteins and peptides | The protein fraction of settled influent solids and of dead biomass. |
| Lipase | Fats, oils and greases | FOG, which floats and consolidates rather than settling out on its own. |
| Amylase | Starches and complex carbohydrates | Carbohydrate load, typically heaviest on food-processing influent. |
| Cellulase | Cellulose | Plant fibre and paper, which is a large share of a municipal blanket. |
Why Bacillus, and why a dry format costs nothing
Bacillus is the single most important bacterial source of exactly these enzymes, proteases in particular. It also forms endospores — a dormant state that survives drying, heat and time essentially intact, then germinates on contact with water and food. For this job the organisms that do the work are precisely the ones that dry best, which is why the two lead formats are dry and why that costs nothing biologically. Nitrifying organisms are the opposite case: they do not survive drying at all, which is why no dry product can address an ammonia permit.
What the published work supports
Mixtures of protease, cellulase and lipase reduce total suspended solids by 30 to 50 per cent and improve settling, with protease and cellulase together outperforming either alone. One controlled study reported 33 per cent volatile suspended solids reduction.
These figures are the mechanism, not a claim about this product: the peer-reviewed enzyme and hydrolysis work they rest on is collected in the scientific literature.
05Microbiological specification
The figures, and what each one is measured against.
Figures stated in the supplied manufacturer and matched private-label product documents are shown here. Where those documents publish no numerical value, the row says so rather than presenting an estimate or implying the source files have not been checked.
