Nanobubbles
Nanobubbles for surface cleaning: how to test
Compare nanobubble cleaning with a control: residual soil, material, temperature, detergent, energy and the distinction between removal and disinfection.
Read articleNanobubblesNanobubble irrigation: root oxygen and salinity
How to test nanobubbles in irrigation: oxygen in water and the root zone, salinity, drainage, control sectors and agronomic acceptance criteria.
Read articleNanobubblesNanobubbles in aquaculture: oxygen, CO₂ and trials
What to measure when testing nanobubbles in aquaculture: DO, CO₂, feeding load, nitrification and controls for assessing oxygenation without growth promises.
Read articleNanobubblesOzone and nanobubbles: demand, residual and CT
Distinguish ozone dose, water demand and residual concentration. Interpret CT, hydraulics and by-products when assessing nanobubble ozone contact.
Read articleNanobubblesNanobubble kLa: dynamic testing and temperature
Measure kLa in nanobubble oxygenation: oxygen curves, saturation, probe response, temperature correction and the difference between clean water and wastewater.
Read articleNanobubblesMeasuring nanobubbles: NTA, DLS and gas identity
Interpret NTA and DLS for nanobubbles: hydrodynamic size, concentration, matrix blanks and controls to distinguish gas-filled objects from solids and droplets.

Nanofiltration or RO: select for the salts that matter
Compare NF and RO by ionic selectivity, hardness, sodium and target quality. Learn what a projection must show before choosing a membrane process.
Read articleReverse osmosis and reuseHydrogen sulphide in well water and RO
Review H₂S before RO: passage into permeate, oxidation and sulphur deposits. Define sampling, abstraction and post-treatment interfaces for the whole plant.
Read articleReverse osmosis and reuseIron and manganese before RO: treating well water
Distinguish dissolved and precipitated metals before RO. Review oxidation, solids separation and air ingress to prevent deposits in filters and membranes.
Read articleReverse osmosis and reuseNitrate in well water: assessing reverse osmosis
Assess nitrate treatment with consistent analytical units, permeate targets and a concentrate balance. Define the data needed to compare RO and blending.
Read articleReverse osmosis and reuseBoron removal in seawater RO: pH and passes
Design boron control separately from conductivity in desalination. Review membrane choice, temperature, pH and full or partial second-pass treatment.
Read articleReverse osmosis and reuseMaximum RO recovery: what limits the design
See how higher RO recovery changes concentration, pressure and element flow. Define an achievable operating envelope before reducing concentrate volume.
Read articleReverse osmosis and reuseSelecting an RO antiscalant from water analysis
Compare RO antiscalants using feed composition, recovery and compatibility. Separate precipitation control from solids removal and define a dosing basis.
Read articleReverse osmosis and reuseRO cartridge filters: micron rating and feed flow
Select an RO safety filter by absolute rating, feed flow and pressure drop. Understand why frequent cartridge replacement points to a pretreatment problem.
Read articleReverse osmosis and reuseRO pressure drop: locating a restriction
Interpret RO pressure loss by stage and flow. Check instruments, pretreatment and deposit patterns before raising pressure or selecting a cleaning procedure.
Read articleReverse osmosis and reuseHigh RO permeate conductivity: finding the cause
Locate rising RO conductivity with stage samples, flow checks and seal inspection. Distinguish changing feedwater, bypass leakage and membrane damage.
Read articleReverse osmosis and reuseNormalising RO permeate flow and salt passage
Separate temperature and pressure effects from RO deterioration. Learn which records and reference conditions make normalised performance trends useful.
