Dry water-soluble pouch, high concentration

SediLogic Maintain Plus

SediLogic Maintain's duty at a much higher concentration, in the same dry water-soluble pouch. The same organisms aimed at the same place — organic load carried in the water column — with far more of them in every pouch, so a large or long programme arrives as fewer pails to freight, store and handle.

01Why this format

Maintenance dosing and general organic load

Concentration changes one thing: how much carrier you buy alongside the culture. Most of the mass of a standard-strength product is not the organisms, and on a big system that is a great deal of weight shipped, stored and handled for no treatment. This is the same blend with the ballast taken out, in the same pouch, dosed into the same place. It is not a stronger treatment and should not be bought as one — a lagoon responds only to its volatile fraction, and that ceiling does not move with concentration. Nor does concentration change which vehicle reaches the bottom: a settled blanket is still the sinking solid's job.

It works in the water column, and it suits a large or long programme where standard-strength pail counts add up.

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

Pack price
$3,708Indicative. Freight, tax and the final price are settled in the reviewed quote.
Dose rate
Not publishedNo dose method is published for this concentration, so no quantity is sized for it. A rate written for the standard-strength blend does not transfer to a stronger one, and the quantity is settled with a person rather than scaled.
Storage
Store dry and cool, away from direct sunlight; keep the container tightly closed.

03When not to buy this

When this product is the wrong answer.

  • The system is small enough that standard-strength pails are already a manageable count. Concentration earns its place on volume, and below that it is simply a larger unit to buy.
  • There is an established sludge blanket to reduce. A blend dispersed through the water column is the wrong vehicle for material sitting several feet below it, and concentration 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, whatever its concentration.

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

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.
AmylaseStarches and complex carbohydratesCarbohydrate load, typically heaviest on food-processing influent.
CellulaseCellulosePlant 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.
