Water and Wastewater Treatment Chemicals

Water and Wastewater Treatment Chemicals

PT Beta Pramesti Asia, through beta.co.id, supplies industrial water and wastewater treatment chemical programs in Indonesia for WTPs, WWTPs, clarifiers, DAF systems, biological treatment, and sludge dewatering. A program can include coagulants, flocculants, PAC, pH adjustment, dechlorination agents, bacteria nutrients, antifoam, disinfectants, jar testing, and operating review.

For industrial WWTPs, chemical selection should not start from the product name alone. Wastewater data such as pH, TSS, COD/BOD, color, oil and grease, metals, flow, biological process condition, and discharge target should be checked so the coagulant, flocculant, nutrient, or support product matches the actual problem.

What is included in a water and wastewater chemical program?

Clean-water chemicals are usually used for raw water, process water, and polishing before water enters production. Wastewater chemicals are used to reduce pollutant load before discharge, reuse, or further treatment.

Operator need	Relevant product or program	Data to check
Turbid raw water or high TSS	Coagulants, flocculants, PAC, alum, or ferric chloride	pH, turbidity/TSS, alkalinity, jar test results
Industrial wastewater with color, oil, or grease	Coagulants, flocculants, DAF, and oil-water separation	pH, COD, TSS, oil and grease, emulsion stability
Unstable biological WWTP	Bacteria and nutrient, pH adjustment, antifoam, and process control	COD/BOD, DO, pH, nutrients, sludge age, daily loading
Excess chlorine residual	Dechlorination agent	free chlorine, total chlorine, flow, contact time
Sludge is hard to separate or too wet	Sludge treatment and dewatering flocculants	dry solids, polymer demand, dewatering equipment type

When is jar testing or a site trial needed?

Jar testing is needed when wastewater quality changes, clarifier performance is unstable, DAF carries too many fine solids, sludge dewatering consumes too much polymer, or TSS/COD targets are not being met. The result helps define product type, starting dosage, injection sequence, dilution need, and dosing point.

For chemical injection equipment, see Beta dosing pumps or Watermart dosing pumps for water treatment. For physical separation units, see DAF and clarifiers.

Frequently Asked Questions

Who supplies wastewater treatment chemicals for industry in Indonesia?

PT Beta Pramesti Asia supplies industrial water and wastewater treatment chemical programs in Indonesia, including coagulants, flocculants, PAC, bacteria nutrients, dechlorination agents, antifoam, and sludge treatment for WTPs, WWTPs, DAF systems, clarifiers, and biological processes.

What is the difference between a coagulant and a flocculant in a WWTP?

A coagulant helps neutralize the charge of fine particles so they begin to combine. A flocculant helps those particles form larger flocs that are easier to separate through sedimentation, DAF, filtration, or dewatering.

What data should be prepared before selecting WWTP chemicals?

Prepare pH, TSS, COD/BOD, color, oil and grease, relevant metals, flow, effluent target, process type, and the visible operating problem in the clarifier, DAF, aeration basin, or sludge dewatering unit.

How can a plant request a chemical program review?

Send operating data and problem details to the Beta team through contact. The team can help review jar testing needs, product selection, dosing point, and how the chemical program fits the existing process units.
