Ozone Treatment
When chlorine and UV together can't deliver the guest-grade taste, colour and odour the brief demands.
The technology explained.
Ozone is generated on-site from oxygen or dry air using high-voltage corona-discharge cells, then dissolved into the water in a contact chamber. It oxidises microorganisms and organic compounds and decomposes back to oxygen within minutes, leaving no residual. CT (concentration × time) is engineered against the relevant disinfection rule for the application.
- Inactivates bacteria, viruses and protozoan cysts (Cryptosporidium and Giardia) at validated CT values.
- Oxidises iron, manganese and hydrogen sulphide ahead of media filtration.
- Removes colour, taste and odour compounds — including geosmin and MIB — that chlorine cannot touch.
- Pre-oxidises dissolved organic carbon ahead of activated carbon for deeper polish.
- Leaves no chemical residual in the treated water.
- Premium lodges and food/beverage sites where guest-perceived water quality must be exceptional.
- Surface-water plants with persistent taste, colour or organic problems.
- Pool and spa hybrid systems looking to cut chemical load and disinfection by-products.
- Wastewater tertiary disinfection where bromate formation can be controlled.
- ×Not a distribution residual — protection ends at the contact-chamber outlet; a small chlorine dose is added for long pipe networks.
- ×Capital and energy cost is meaningful — over-spent on simple, clean feeds where UV alone is enough.
- ×Off-gas destructors and safety interlocks are mandatory; the plant cannot be casually operated.
- ×Bromide-bearing waters can form bromate (a regulated disinfection by-product) — feed chemistry must be checked first.
Where Ozone Treatment is used.
- Taste, odour and colour polishing of drinking water
- Manganese, iron and sulphide oxidation
- Pool and spa disinfection (low-chemical hybrid systems)
- Pre-treatment to activated carbon for organics removal
- Wastewater tertiary disinfection
How HidroVerse deploys Ozone Treatment.
We deploy ozone where chlorine and UV together cannot deliver the guest-grade taste, colour and odour the brief demands. Generator sizing, contact-chamber design, off-gas destruction and CT compliance are part of the engineered package — never a bolt-on cartridge.
A typical Ozone Treatment treatment chain.
Ozone is a powerful oxidiser and a real engineered process — generator, contactor, off-gas destruction and safety interlocks are all part of the package.
Pre-treatment
Particulate removal upstream so the contactor is not loaded by suspended matter. Bromide screening on the feed — bromate formation is the risk to manage.
Core stage
On-site ozone generation from oxygen or dry air; controlled injection into a contact chamber sized for the CT target; ORP feedback control on dosing.
Post-treatment
Off-gas destructor on the contactor headspace; activated-carbon polishing where ozone has pre-oxidised dissolved organics; small chlorine residual on distribution.
Waste handling
Off-gas is destroyed (thermal or catalytic) before atmospheric release; ozone process is closed-loop within the reactor — no waste stream to the environment.
Buyer's guide.
The questions every commercial buyer should put on the table before signing for a water system. Can't see yours? Send us a brief — a HidroVerse specialist replies within one business day.
Yes — we keep a current reference list organised by application and scale. After a short qualifying call we release names, contacts and (with the host's permission) site-visit options. The conversation between two operations managers is the most honest reference we can offer; we do not gate-keep it.
We start with a SANAS-accredited feed-water panel, profile your demand against verified occupancy or production data (not brochure numbers), and specify against the worst-credible feed and peak demand — with disclosed margins. If a simpler technology will hit the brief, we'll specify the simpler technology and tell you why. We do not earn more by over-spending you; we earn more by you renewing service contracts year after year.
PFD, P&IDs, sizing calculations against verified influent data, equipment schedules with serial numbers, control philosophy, pre-treatment justification, waste-handling and regulatory compliance trail. Audit-ready by an external ECSA-registered engineer is the standard we design to — not a brochure pack with marketing fluff.
Pre-treatment is technology-specific (sediment, hardness, chlorine, biological load) and non-optional. Skipping it is the single largest cause of premature failure on every membrane, media bed and disinfection stage. Watch for suppliers quoting only the core stage — they are selling you a 12-month problem.
Every consumable and major component has a quantified replacement trigger (differential pressure, flow drop, UV intensity drop, salt-passage drift). Replacement schedules and trigger limits are written into the HidroVerse Care contract — visible, auditable and triggered on monitoring data, not guesswork.
Critical components are specified with duty/standby and automatic fail-over so a single failure does not stop supply. Our SLA on critical lines is 4 hours on site; the median lived response over the last 14 months is 2 hours 40 minutes. Telemetry triggers tickets before the operator notices — most failures are flagged, not phoned in.
Continuous telemetry on flow, pressure, conductivity, turbidity and on-skid water quality. Monthly SANAS-accredited compliance sampling is included on HidroVerse Care — not invoiced piecemeal. The audit pack builds itself monthly so when DWS or your insurer arrives, the file is ready in 30 minutes.
Potable applications: SANS 241:2015 (mandatory under the Water Services Act 108 of 1997), the National Water Act 36 of 1998 for abstraction and discharge, NSF/ANSI component certification, WHO Guidelines for design margin. Wastewater: the relevant DWS discharge authorisation under General Authorisation 665 or a site-specific Water Use Licence. We sign off against the legal floor and design to a margin above it.
Survey 1–2 weeks, design 2–4 weeks, install 4–10 weeks, commissioning and proof of compliance 1–2 weeks — typically 8–14 weeks for a lodge or estate, longer for mining and municipal. Delays come from civil works, third-party council approvals and architectural changes; the engineered scope rarely slips.
Survey, lab analysis, design pack, equipment, install, commissioning, operator training, the first year of monthly compliance sampling and the agreed scope of HidroVerse Care. Civils, electrical reticulation, third-party council fees and any architectural integration work are quoted separately and scheduled into the contract. If your quote has 'allowances' and 'provisional sums' across the page, you are buying a future invoice.
