Biological Wastewater Programme | Beta Pramesti Asia

Biological wastewater treatment depends on stable biomass, retention time, aeration, nutrients, pH, temperature, and solids separation to treat biodegradable organic load. Supplemental bacteria, enzymes, or nutrients should be evaluated only after the incoming load, biomass condition, oxygen supply, and potential toxicity have been reviewed together.

PT Beta Pramesti Asia, through beta.co.id, supports industrial wastewater treatment in Indonesia with process evaluation, Biological Booster for bioaugmentation, biological bacteria and nutrients, aerobic and anaerobic systems, SBR, MBBR, MBR, dosing, and monitoring. This page helps buyers distinguish an operating correction from a supplemental-product requirement.

Which biological-process upset should be checked first?

Diagnosis should use several days of trends under comparable process conditions. One COD result, sludge colour, or odour is not enough to define the cause or a product dose.

Operating symptom	Data to review	Response to evaluate
Rising effluent COD/BOD	Flow and load, COD/BOD ratio, pH, temperature, DO/ORP, retention time, recycle, and production changes	Stabilise load/equalisation, aeration, pH, and sludge age before assessing bioaugmentation
Weak floc or sludge washout	MLSS/MLVSS, SVI or settling test, clarifier blanket, RAS/WAS, filaments, and hydraulic load	Correct solids separation and sludge control; test coagulant/flocculant only when it fits the process objective
Slow biomass recovery after an upset	Toxicant history, salinity, temperature, solids loss, microscopy, and OUR/SOUR trends where available	Remove the inhibition source, restore conditions, then test a bacterial culture against a control
Suspected nutrient deficiency	Biodegradable COD/BOD, nitrogen, phosphorus, alkalinity, and actual consumption from the same period	Confirm deficiency before adding biological nutrients; avoid a universal ratio without data

The U.S. EPA Process Control Manual for Aerobic Biological Wastewater Treatment Facilities treats operating records, system observations, and laboratory data as one process-control basis. That principle supports diagnosis; effluent and acceptance targets still follow the facility permit, design, and procedure.

Biological product candidates

BETAGARD 5300

Enzyme bacteria for wastewater treatment plant

BETAGARD 5300 is an enzyme/bacteria product candidate for evaluation in industrial and domestic wastewater treatment. Suitability, dose, storage, and process response should follow the current TDS/SDS and a controlled site trial.

BETAGARD 5310

Enzyme bacteria for wastewater treatment plant

BETAGARD 5310 may be evaluated for streams with particular organic characteristics after the source, load, biomass condition, and upset cause have been defined. Use a baseline and control to assess the response.

BETAGARD 5330

Bacterial cultures

BETAGARD 5330 is a bacterial culture that may be evaluated for bioaugmentation. It does not replace corrections to aeration, pH, solids retention, solids separation, or toxicant control.

How should a biological product be trialled?

1. Establish the baseline for load, effluent quality, DO/ORP, pH, temperature, MLSS/MLVSS, settling, sludge wasting, and product consumption.
2. Confirm the problem and operating corrections already made; do not change several primary variables at the same time.
3. Verify the product, batch, TDS/SDS, storage, activation or dilution where required, injection point, and dose basis.
4. Run a controlled trial with an agreed period and acceptance criteria. Record improvement, no change, and deterioration.
5. Accept the programme only when trends improve without transferring the problem to the clarifier, sludge, odour, nutrients, or disposal route.

For process selection, compare activated sludge, MBBR, SBR, and MBR. A biological product does not replace verification of the main process capacity.

Buyer questions

When is supplemental bacteria worth testing?

Bioaugmentation is worth testing after inhibition, biomass loss, aeration, pH, temperature, nutrients, and solids separation have been checked. Start-up, recovery after an upset, or a new load can justify a trial, but results need a clear baseline.

Does every biological plant need supplemental nutrients?

No. Add nutrients only when influent and biomass data from the same period show a deficiency relative to the biodegradable load. Excess nitrogen or phosphorus can add effluent load and cost.

Which data should be sent for an evaluation?

Send the process diagram, volume/flow, influent and effluent analyses, DO/ORP, pH, temperature, MLSS/MLVSS, settling/SVI, RAS/WAS, aeration, sludge age, product consumption, upset history, and permit target through the Beta Pramesti Asia contact page.
