Algae & Biology
Green Water or Surface Algae
Possible causes
Nutrients, sunlight, warm water, low circulation or seasonal conditions.
Recommended testing
Identify algae where possible; record area, depth, temperature,
nutrients and circulation.
Treatment pathway
Puroxi algae bottle test, circulation review and suitable
ultrasonic or oxygenation pathway.
Investigate promptly if the water is used by people or animals.
Algae & Biology
Cyanobacteria or Suspected Harmful Bloom
Possible causes
Nutrient enrichment, warmth, calm conditions and a stable upper water column.
Recommended testing
Use qualified identification and toxin testing where exposure is possible.
Treatment pathway
Restrict exposure, follow local health guidance and design a verified control plan.
Urgent where people, livestock, pets or aquatic life may be exposed.
Oxygen
Low Dissolved Oxygen
Possible causes
High biological load, warm water, stratification, decaying organics
or inadequate circulation.
Recommended testing
Measure dissolved oxygen by depth and time of day with temperature
and biomass information.
Treatment pathway
Aeration, Puroxi Nano Bubble oxygenation, circulation and load management.
Emergency action may be required when fish or animals are distressed.
Odour
Rotten-Egg or Septic Odour
Possible causes
Hydrogen sulphide, anaerobic zones, sulphur bacteria or decaying organic material.
Recommended testing
Test source and distribution water; inspect tanks, wells, sludge and stagnant zones.
Treatment pathway
Oxidation, oxygenation, cleaning, filtration and source-specific treatment.
Ventilate and obtain professional guidance in confined or high-gas conditions.
Sediment
Sludge and Organic Buildup
Possible causes
Settled solids, feed waste, manure, algae decay or poor hydraulic movement.
Recommended testing
Assess depth, solids, organic loading, inflows and oxygen at the sediment interface.
Treatment pathway
Source control, removal, circulation, oxygenation and biological-process support.
Prioritize when odour, oxygen demand or process capacity is affected.
Aquaculture
Fish Stress or Unexplained Mortality
Possible causes
Low oxygen, temperature, ammonia, nitrite, toxins, disease,
crowding or poor water exchange.
Recommended testing
Immediately measure DO, temperature, pH, ammonia and nitrite;
involve aquatic-health professionals.
Treatment pathway
Emergency oxygen, load correction and a complete water-quality investigation.
Urgent—do not assume equipment alone will solve disease or toxicity.
Biology
Biofilm, Slime or Plugged Lines
Possible causes
Microbial growth, nutrients, iron bacteria, low flow and dirty
storage or distribution.
Recommended testing
Inspect the complete system and obtain microbial and water-chemistry information.
Treatment pathway
Cleaning, disinfection, controlled dosing, filtration and flow correction.
Prioritize where drinking systems or production equipment are affected.
Safety
Bacterial Test Failure
Possible causes
Source contamination, poor well construction, storage hygiene,
biofilm or inadequate disinfection.
Recommended testing
Use an accredited laboratory and follow local drinking-water instructions.
Treatment pathway
Protect users, correct the source and system, disinfect and verify
before declaring water safe.
Urgent for human or animal consumption.
Scale
Hard Water and Scale
Possible causes
Calcium and magnesium crystallize as pressure, temperature or
concentration changes.
Recommended testing
Hardness, alkalinity, pH, conductivity, temperature and equipment inspection.
Treatment pathway
Puroxi Descaler, softening or other site-specific scale-management treatment.
Address before heat-transfer loss or equipment damage becomes severe.
Metals
Iron or Manganese
Possible causes
Naturally dissolved metals, reducing groundwater or distribution deposits.
Recommended testing
Test dissolved and total iron/manganese, pH, alkalinity, turbidity and bacteria.
Treatment pathway
Oxidation, retention, filtration and controlled system cleaning.
Prompt review when staining, plugging or microbial growth is increasing.
Process
Foam or Cloudy Water
Possible causes
Surfactants, proteins, fine solids, biological activity, gas,
algae or treatment imbalance.
Recommended testing
Record when it occurs and test turbidity, organics, pH,
process chemistry and biology.
Treatment pathway
Identify the source before adding treatment; improve separation,
filtration or process control.
Urgency depends on use and whether toxicity or process failure is suspected.
Livestock
Poor Weight Gain, Feed Conversion or Conception
Possible causes
Water palatability, restricted flow, mineral load, biofilm,
pathogens, heat or non-water health factors.
Recommended testing
Complete water test, peak-demand drinker flow, intake observations
and performance comparison.
Treatment pathway
Correct flow and plumbing, clean systems, apply a verified Puroxi
water protocol and involve the veterinarian.
Prompt veterinary investigation when animals are sick, dying or conception is declining.
Livestock
Animals Playing With or Wasting Water
Possible causes
Low flow, poor palatability, temperature, drinker problems,
pressure variation or animal behaviour.
Recommended testing
Measure drinker flow at peak demand; inspect pressure, valves,
plugging and water quality.
Treatment pathway
Restore adequate delivery, correct equipment and address taste,
odour, biofilm or mineral problems.
Prompt action prevents dehydration, wet bedding and production loss.
