01Why this format

General organic load on large systems

On a big system a standard-strength programme runs to a lot of pails, and most of that weight is carrier rather than organisms. A concentrate delivers the same organisms in far less material. That is a freight-and-handling saving, not a stronger product: the lagoon still responds only to its volatile fraction, and that ceiling does not move with concentration. It does the water-column job — for an established benthic blanket the dense sinking solid is still the tool, at any concentration. Because it earns its place on volume, a concentrate order is confirmed with a person rather than sized in the planner.

It works in the water column, and it suits a large lagoon where standard pouch counts get unwieldy.

02Specifications

What is published, and what is not.

Each figure below is taken from a product document. Where the documents publish no value, the row says so rather than carrying an estimate: a number that later moves is worse than a stated blank, because an operator may have sized an order around it.

Pack size: 25 lb pail containing 25 × 1 lb water-soluble pouches
Pack weight: 25 lb
Shipping weight: 25.22 lbGross weight as shipped, including packaging.
Pack price: $4,712Indicative. Freight, tax and the final price are settled in the reviewed quote.
Dose rate: Sized on review from the manufacturer's dosing method (rev. 2026-07-16) at one-tenth the standard Maintain mass. The planner identifies when a large-system programme merits the concentrate, then a person confirms the whole-pail quantity.The concentration changes the mass to ship and handle, not the dose of viable organisms delivered to the lagoon.
Storage: Store dry and cool, away from direct sunlight; keep the container tightly closed.A temperature-controlled storage range of 50–90°F is specified on the product documentation.

03When not to buy this

When this product is the wrong answer.

The system is small enough that standard Maintain pouches are already a manageable pail count. The concentrate earns its place on volume; below that it is simply a larger unit to buy.
There is an established sludge blanket to knock down. A soluble pouch disperses through the water column, and reaching a blanket several feet down is the dense sinking solid's job — concentration does not change that.
An ammonia or nitrogen permit is the actual problem. Nitrifying bacteria do not survive drying, so no dry product, concentrated or not, can address nitrification.

The dosing planner screens for each of these 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 classes produced by Bacillus and the material each acts on
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.

Peer-reviewedControlled studyEnzyme mechanism. Field efficacy figures in this category are measured by the seller rather than independently, ours included, and are labelled that way.

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.

The figures, and what each one is measured against.

Figures published in the product documents are shown here. Where the documents publish no numerical value, the row says so rather than carrying an estimate.

Viable count at manufacture: 40 billion CFU/gA count published on the product sheet; no end-of-shelf-life guarantee is stated.
Guaranteed count at end of shelf life: Not publishedNo guaranteed viable count at the end of the stated shelf life is published for this product.
Strains in the blend: 7 Bacillus strains
Operating temperature range: Apply at 50°F or warmerAn application threshold taken from the product label, not a full tolerance range.
Operating pH range: Not publishedNo numerical operating pH range is published for this product.
Biosafety level: Not publishedThe product documentation describes the bacteria as non-pathogenic but publishes no Biosafety Level designation.
Shelf life: 24 months

The range

Other formats, and what each one is for

Which product fits is a question of where the material sits and how the system is dosed, not of which is stronger. Only a sinking solid reaches a settled blanket; a pouch or a liquid works on what the water column is carrying.

Elsewhere in the range

What this product acts on

It digests organic solids. It reduces volatile solids, degrades fats, oils and grease as material, improves settling and reduces accumulated sludge depth where conditions permit.

It is not claimed to control algae, to kill or suppress pathogens, to disinfect or sanitise, to control odour-causing organisms as organisms, or to have any antimicrobial effect. Under US EPA guidance on determining whether a product is a pesticide under FIFRA, claims that a product cleans, reduces or removes sludge are not considered pesticidal. It acts on material, not on organisms.

Only the volatile organic fraction is treatable. Sand, grit, silt, mineral precipitates and plastics are not biodegradable and remain at any dose. Elimination of sludge is not an achievable outcome and is not claimed.
