cooling tower
Biocides
Cooling tower biocides for controlling bacteria, algae, fungi, biofilm, and slime in industrial cooling-water systems in Indonesia.
Short Answer
Cooling tower biocides are used when circulating water shows slime, algae, biofilm, odour, high microbiology results, or Legionella risk. PT Beta Pramesti Asia, operating through beta.co.id, supplies biocide programmes for industrial cooling towers in Indonesia as part of the Betagard cooling-water treatment range. Biocide selection should not stand alone: the technical review usually checks pH, temperature, ORP or oxidant residual, TPC, dosing pattern, blowdown, basin condition, and whether scale or corrosion also needs control.
For the complete programme, see Betagard Cooling Tower Chemicals, scale inhibitors, corrosion inhibitors, dispersant chemicals, and cooling tower cleaning service. For chemical injection, see Beta dosing pumps or Watermart dosing pumps.
When is a cooling tower biocide needed?
| Operator question | Field symptom | Programme usually reviewed | Data to check |
|---|---|---|---|
| Who supplies cooling tower biocide in Indonesia? | The cooling tower needs routine microbiological control | Betagard biocide programme, dosing schedule, and field monitoring | System volume, circulation flow, temperature, pH, TPC, ORP, and blowdown pattern |
| How do I control slime or biofilm? | Slippery basin surfaces, dirty fill, odour, or lower heat transfer | Oxidising or non-oxidising biocide, with biodispersant where needed | Basin condition, deposit photos, TPC, oxidant residual, and dosing history |
| When should algae be controlled? | Green growth in open areas, splash zone, or basin | Biocide programme and physical tower housekeeping | Sun exposure, basin cleanliness, water circulation, and blowdown frequency |
| Why is the biocide programme unstable? | Microbes return quickly, dosage rises, or test results vary | Review pH, contact time, injection point, dispersant, and cleaning need | pH, ORP, chlorine residual, TPC, biofilm, and cleaning schedule |
| Is tower cleaning needed? | Biological deposit is already thick or chemical treatment is no longer enough | Cooling tower cleaning service, followed by chemical programme reset | Deposit area, tower material, shutdown plan, and circulating-water condition |
Betagard biocide options
- BETAGARD 5012 Oxidizing Biocide - combines chlorine oxidising power for bacterial control in industrial water systems.
- BETAGARD 5050 Non Oxidizing Biocide - formulated to control microorganisms in open and closed circulating water systems.
- BETAGARD 5080 Biocide - a fast-acting broad-spectrum biocide for algae, bacteria, and fungi in recirculating water.
- BETAGARD 5090 Oxidizing Biocide - used as a disinfectant agent in recirculating water systems to help keep water clean and clear.
Data to prepare before recommendation
Prepare pH, temperature, conductivity, TDS, cycle of concentration, oxidant residual or ORP, TPC result if available, basin condition, injection point, blowdown pattern, and previous dosing history. If the system also has scale, corrosion, or suspended deposits, hardness, alkalinity, chloride, sulfate, silica, and heat-exchanger metallurgy help Beta decide whether the biocide programme should be combined with scale inhibitor, corrosion inhibitor, or dispersant.
Common Questions
What is a cooling tower biocide?
A cooling tower biocide is a chemical used to control bacteria, algae, fungi, biofilm, and slime in circulating cooling-tower water. The programme is usually monitored through ORP, oxidant residual, microbiology tests, basin condition, and system operating trends.
Should I use an oxidising or non-oxidising biocide?
It depends on the water condition and control target. Oxidising biocide is useful for routine control with measurable residual, while non-oxidising biocide is often used as a companion or rotation when biofilm and microorganisms are harder to control. Selection should consider pH, system materials, microbiological load, and compatibility with the rest of the chemical programme.
Is biocide alone enough for a cooling tower?
Not always. Biocide controls microbiology, but it does not solve mineral scale, metal corrosion, suspended solids, or hard deposits. A troubled cooling tower often needs a combined programme: biocide, dispersant, scale inhibitor, corrosion inhibitor, blowdown control, and physical cleaning.
When should I contact Beta?
Contact Beta when a cooling tower shows slime, algae, biofilm, odour, high TPC, reduced chiller efficiency, or the need for a more stable biocide dosing schedule. Send operating data through the Beta contact page so the technical team can review the programme options.
