SediLogic Maintain Plus — high-strength pouch

01Why this format

Maintenance dosing and general organic load

This grade contains less carrier relative to the culture. Higher concentration can reduce handling, but it does not increase the treatable fraction or deliver the blend to the bottom sludge. Only volatile organic solids respond; a settled blanket still needs a sinking solid.

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

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 the planner gives no quantity. Contact us for review. We do not scale the standard-strength blend's rate.
Storage: Store dry and cool, away from direct sunlight; keep the container tightly closed.

03When not to buy this

When to consider another approach

Standard-strength pails already give you a manageable order. Consider the standard grade for smaller systems.
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 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
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 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.

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.
