Dry water-soluble pouch, cold-weather blend

Sedivore Polar

SediLogic Maintain's duty, in a blend built for cold water. A soluble pouch that disperses through the water column and goes on digesting organic material at temperatures where a standard blend has effectively stopped — for a lagoon whose incoming load does not slow down simply because the water has.

A white plastic pail with a plain printed label, beside a sealed bag of dry brown granular material and a loose pile of the same on a white background.

Freight is added at checkout, and an order on a pallet is quoted before it ships. A person reads every order against the lagoon it is going to, and says so if the quantity looks wrong for the system.

01Why this format

Organic load in a lagoon running cold

Biological activity falls away as water cools, and most blends in this category are built on organisms that do very little below about 50°F. That is the ordinary reason a winter programme is a wasted one. This blend is selected for cold conditions instead, and it costs more: the same 25 lb pail is $632 here against $516 for the standard pouch, which is the plainest statement of the trade this product asks you to make. It is the narrower of the two pouches, deliberately — where the water is not genuinely cold, SediLogic Maintain does the same work for less, and where the target is a settled blanket a sinking solid is the right vehicle at any temperature.

It works in the water column, and it suits an adequately mixed lagoon working through cold water.

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.

03When not to buy this

When this product is the wrong answer.

  • The water is not genuinely cold. The cold-weather grade costs $632 the pail against $516 for the standard one, so above roughly 50°F SediLogic Maintain does the same work for less; this grade earns its place only where low temperatures would otherwise stall the programme.
  • There is an established sludge blanket to reduce. A soluble pouch disperses through the water column, and material sitting several feet below it is the sinking solid's job — water temperature does not change which vehicle reaches the blanket.
  • The lagoon is poorly mixed, since dispersal through the water column is the entire mechanism and poor mixing removes it.
  • An ammonia or nitrogen permit is the actual problem. Nitrifying bacteria do not survive drying, so no dry product can address nitrification — a cold-weather blend included.

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.

ProteaseProteins and peptidesThe protein fraction of settled influent solids and of dead biomass.
LipaseFats, oils and greasesFOG, which floats and consolidates rather than settling out on its own.

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.
