Dry water-soluble pouch

SediLogic Maintain

A soluble pouch for maintenance dosing and organic load in a well-mixed water column. For an established bottom sludge blanket, use a sinking solid.

Two sealed transparent packets of dry, brown granular treatment material on a plain 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

Maintenance dosing and general organic load

Maintain disperses in the water column. It is intended for ongoing organic load, rather than direct delivery to settled bottom sludge.

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

Dose rate
Sized to your lagoon from the manufacturer's dosing method (rev. 2026-07-16): an ongoing maintenance dose applied to the average flow across the programme, scaled to influent strength. The dosing planner returns the quantity and an indicative cost for your system.Concentration-based and system-specific rather than a fixed per-pail rate; sized to whole pails by the planner and confirmed in the reviewed quote.
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 to consider another approach

  • There is an established sludge blanket to reduce. That is what the sinking solid is for, and a pouch dosed at the surface is the wrong tool for it.
  • 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.

The planner checks these conditions before calculating a quantity.

04Microbiology

How bacteria break down organic sludge

The mechanism is enzymatic hydrolysis. Bacillus species release enzymes that break large organic molecules into smaller, soluble fragments. Bacteria then take up and metabolise those fragments.

Enzyme classes produced by Bacillus and the material each acts on
EnzymeActs onWhat that is, in a lagoon
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 works in dry treatments

Bacillus produces these enzymes and forms spores that tolerate drying and storage. The spores germinate when conditions are suitable. This makes Bacillus useful in dry sludge treatments. These products are not intended to address an ammonia permit; that requires a separate assessment of nitrification.

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 studies explain the mechanism; they do not predict results from a SediLogic product. The research is collected in the scientific literature.

The range

Other formats, and what each one is for

Choose the format according to where the material has accumulated and how you apply treatment. Sinking solids target settled bottom sludge. Soluble pouches and liquids disperse in the water column.
