Liquid concentrate
SediLogic Liquid
A liquid concentrate for installations that physically cannot take a solid. It does the same job — digesting organic material — in a format that can be metered or poured where a puck or a pouch would not work.
01Why this format
Installations that cannot take a solid form
This is an answer to a delivery constraint, not a better product, and it is deliberately not promoted as one. Where a solid can be dosed, a solid is what we will specify: a dense solid puts organisms where the material actually sits, whereas a liquid dosed into the same system disperses through it. The liquid exists because some installations leave no other option — not because it is the upgrade. Presenting it as a co-equal third choice would invite operators to pick it when a solid would have served them better, which is how the format decision gets made badly across this category.
It works in the metered or poured, as the installation allows, and it suits systems where a puck or pouch is physically impractical.
02Specifications
What is confirmed, and what is not.
Every figure below comes from a manufacturer document or it is marked as outstanding. Nothing here 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 weight
- Not yet confirmedAwaiting: Sold by volume, not weight. A pound figure would require a density assumption nobody has supplied
- Pack price
- $460Indicative. 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 yet confirmedAwaiting: Manufacturer dose table, in writing, with a document revision
- Storage
- Not yet confirmedAwaiting: Manufacturer technical data sheet — liquids carry storage and shelf-life constraints a dry format does not
- Safety Data Sheet
- Not yet confirmedAwaiting: Manufacturer SDS in OSHA HazCom / GHS format

03When not to buy this
Three situations where this product is the wrong answer.
- A solid form can be dosed at all. If a puck or a pouch will physically work in your system, that is what we will quote, and the liquid would be the weaker choice for the same money.
- The target is an accumulated benthic sludge blanket. A liquid introduced at the surface disperses through the water column instead of concentrating where the blanket sits, which is the whole reason the sinking solid exists.
- You are buying it to satisfy an ammonia or total nitrogen permit. Nitrification requires viable nitrifying organisms, and whether this blend carries them is a question for the manufacturer's written specification — it is not established here, and we will not imply it.
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.
None of these is confirmed yet, and each says what has to arrive before it can be published. A specification with its basis named and its value outstanding is more use to an operator than a number with neither.
