01How the dose is sized
The dose comes from the manufacturer's own method, applied to your lagoon.
This tool selects a format, screens the lagoon, and sizes the dose — an initial knockdown on the treated surface area and an ongoing programme on the flow — from the written dose tables for the products themselves, applied to the numbers you enter and rounded up to whole packs so no application falls short.
Each calculated quantity uses the manufacturer’s written dose method for that product, with its document revision recorded. The solid and soluble-pouch quantities use different tables because they are different blends. The result shows the method used for each line.
Products without a written dose table are listed for discussion, but the planner does not calculate a quantity for them. We do not borrow or scale another product’s rate.
The estimate uses whole packs at the published pack price. Freight, tax and the final price are confirmed in your reviewed quote. Please check your lagoon inputs carefully: an incorrect area or flow will change the quantity calculated.
02Questions
Common questions about dosing.
How much bacteria does a wastewater lagoon need?
It depends on surface area, the objective, water temperature and how much of the accumulation is actually organic. Any supplier quoting a pounds-per-acre figure before knowing those things is quoting a rule of thumb. Dose rates should come from the manufacturer's written dose table for the specific blend, applied to your lagoon's dimensions, and sized to whole packs so that no application falls short of the confirmed requirement.
Do I need a sludge survey before ordering lagoon bacteria?
Not necessarily, though measurement improves the sizing considerably. Surface area and objective are enough to select a format. Knowing the sludge volume and the volatile fraction is what tells you how much of the accumulation is treatable at all, and whether biological treatment is worth starting. SediLogic does not perform on-site sludge surveys, though it can test a sludge sample you send in; if you already hold figures from a survey, we will use them.
Will bioaugmentation work in my lagoon?
Not in every lagoon. Bioaugmentation digests the volatile organic fraction only, so a lagoon whose accumulation is largely sand, grit, silt or mineral precipitate will not respond meaningfully at any dose. It also performs poorly in a lagoon that is not adequately mixed, since mixing and aeration are complementary to biological treatment rather than alternatives to it. A fixed deadline for recovered capacity is a dredging problem rather than a treatment one.
