Organic load in systems a solid cannot be dosed into

Format follows the duty. A dense solid is the only thing that puts organisms down onto a settled benthic blanket, so for an accumulated sludge blanket a solid is what we specify. A liquid disperses through the volume it is dosed into, which is the wrong behaviour for a blanket and the right one for organic load carried in the water — and it is the only format some installations can physically take at all. Where that is the duty in front of us, this is the product for it, built to the same specification as the dry range and benchmarked the same way.

It works in the metered or poured, as the installation allows, and it suits dosing points and flowing systems that take a metered liquid.

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: 5 gal pail
Pack weight: Not publishedSold by volume rather than by weight.
Shipping weight: 41.95 lbIndicative until a filled pail is weighed. Freight is confirmed on the reviewed order.
Pack price: $460Indicative. Freight, tax and the final price are settled in the reviewed quote.
Dose rate: Not publishedNo revision-controlled dose method is published for this format, so no quantity is sized for it.
Storage: Store in a cool, dry place, away from direct sunlight; keep the container closed.

03When not to buy this

When this product is the wrong answer.

Your target is the bottom blanket and a solid can be dosed. A sinking solid carries organisms down onto the material; that is the duty the dry range is built for, and it is what we will quote for it.
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 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 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.
