TREATMENT PROGRAMMES

Complete Programmes, Not Just Chemicals

The best results come from a programme designed around the water analysis and the system, with the right dosing, monitoring and regular service visits.

Cooling tower with chemical dosing skid and controllerCT

COOLING WATER PROGRAMME

Cooling Tower & Closed Loop Treatment

Cooling towers concentrate minerals as water evaporates, and their warm, aerated water is ideal for bacteria and algae. Our programmes control scale, corrosion and microbiological growth, including Legionella risk, while saving water through optimised cycles of concentration.

BIOCIDES & DISINFECTANTS

Oxidising and Non-Oxidising Biocides

Most programmes use an oxidising biocide for routine control, and alternate it with a non-oxidising biocide so organisms cannot adapt and biofilm stays under control.

Chlorine / HypochloriteOxidisingFast, broad kill and measurable residualDrinking water, cooling towers, pools, STP outlet
Chlorine DioxideOxidisingEffective over a wide pH range, penetrates biofilmCooling water, process water, food plants

Selection depends on the system, water quality, materials of construction, discharge rules and local approvals. Some legacy biocides are restricted in certain regions; we recommend only products suitable for your site.

HOW A CHEMICAL PROGRAMME WORKS

Analyse, Dose, Monitor, Improve

The right chemical, at the right dose, at the right point.

We start with a full water analysis and a survey of the system. The programme sets each chemical, its dose rate and dosing point. Chemicals are dosed automatically by SEKO dosing pumps and controllers, and results can be tracked live through IoT monitoring, so the programme is fine-tuned on data, not guesswork.
