SediLogic Liquid Cold — cold-water concentrate

01Why this format

Organic load in liquid-dosed systems running cold

Choose Liquid Cold when the system needs liquid dosing and low water temperatures limit a standard blend. For warmer water, consider the base Liquid product. For settled bottom sludge, ask about a sinking solid.

It works in the metered or poured, as the installation allows, and it suits liquid-dosed systems working through cold conditions.

Storage: Store in a cool, dry place, away from direct sunlight; keep the container closed.

03When not to buy this

When to consider another approach

Your target is the bottom blanket and a solid can be dosed. A dense solid puts organisms at the blanket where the material sits; any liquid, cold-weather or not, disperses through the water column instead.
Water temperatures do not require a cold-weather blend. Consider the base Liquid product.
The target is an accumulated benthic sludge blanket. A liquid introduced at the surface disperses through the column rather than concentrating on the blanket, which is the whole reason the sinking solid exists.

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.
