Product Description

Municipal Foam Control

BWF160 Silicone Foam Control Agent for Municipal Wastewater Treatment

Product ModelBWF160

Ionic CharacterNonionic

pH6-8

Reference Dosage50-300 ppm

Application Overview

Municipal influent can receive detergents, food residues and industrial discharges that create intermittent foam in headworks and biological stages.

BWF160 offers flexible direct or diluted dosing for changing influent conditions and is described for municipal biological treatment systems.

Why Foam Control Matters

In municipal wastewater treatment, uncontrolled foam is not only a visual issue. It can reduce usable tank volume, cause overflow, contaminate walkways, interfere with level instruments and carry solids or liquid into downstream units. A suitable defoamer should therefore be assessed for both immediate foam collapse and resistance to re-foaming under real mixing, pumping or aeration conditions.

BWF160 should be treated as one component of process control. Operators should also investigate the underlying source of foam, including surfactant loading, production changes, biological conditions, aeration intensity, recycle streams and hydraulic turbulence.

Key Product Features

Fast initial defoaming for active surface foam.

Continued foam suppression under water-based process conditions.

Nonionic formulation for broad site-specific compatibility evaluation.

Easy dispersion with no floating-oil appearance when properly selected and applied.

Flexible direct, drip, spray or turbulent-inlet dosing options.

Designed for water-treatment use and described as not causing secondary water pollution under intended application.

Note: Typical information should be confirmed against the current commercial TDS and the actual supplied batch.

Recommended Use and Dosing

The general reference dosage is approximately 50-300 ppm. This is a screening range rather than a guaranteed fixed dose. Actual demand depends on surfactant type, contaminant concentration, temperature, pH, dissolved and suspended solids, aeration, mixing energy and the required duration of control.

BWF160 can be added directly at an inlet with good wastewater turbulence. Where broad surface contact is needed, it may be pre-diluted with clean cold water at a 1-3-fold dilution and applied by drip or spray to the foam-concentrated area. Use clean equipment and avoid preparing more diluted product than the operation can use promptly.

Suggested Site Evaluation

Record the untreated foam height and operating conditions.

Start at a conservative dose and increase stepwise.

Measure both collapse time and the interval before foam returns.

Track foam coverage, overflow risk, aeration stability and daily product use.

Confirm that clarification, biological treatment, filtration or discharge performance remains acceptable.

Process Integration Guidance

Target the specific source rather than blanket-dosing the entire plant. Headworks, equalization returns and aeration-zone inlets should be evaluated separately.

When PAC, PolyDADMAC, polyamine, decoloring agent or polyacrylamide is also used, conduct a compatibility trial with the full treatment sequence. Foam reduction should not be evaluated in isolation from floc formation, settling, flotation, sludge dewatering or final-water quality.

Packaging, Handling and Storage

BWF160 is packed in 25 kg or 200 kg plastic drums. Store sealed containers at normal temperature in accordance with general chemical-storage practice. The stated shelf life is one year. Protect the product from freezing, rotate stock on a first-in-first-out basis and inspect emulsion appearance before use after extended storage.

Frequently Asked Questions

Q: Is BWF160 a silicone defoamer?

A: Yes. The supplied information describes a polysiloxane-based formulation with synergist, emulsifier and dispersant.

Q: Can BWF160 be diluted before dosing?

A: Yes. Clean cold water can be used for a 1-3-fold pre-dilution when drip or spray distribution is preferred. Confirm the practical dilution procedure on site.

Q: What is the recommended dosage?

A: A general reference range is approximately 50-300 ppm. The optimum dose must be established using the actual foaming water and operating conditions.

Q: Can it be used in biological wastewater treatment?

A: The product is described for municipal biological treatment systems and as not affecting activated-sludge bacterial reproduction under intended use. A controlled site trial and routine biological monitoring are still recommended.

Q: How should it be stored?

A: Keep the sealed drums at normal temperature, protect them from freezing and use first-in-first-out stock rotation. The stated shelf life is one year.

Why Work with Bluwat Chemicals

Bluwat Chemicals supplies water-treatment chemicals for industrial and municipal applications. The commercial approach combines product selection, sample evaluation and application discussion so that buyers can qualify a grade against their own water, equipment and treatment objectives. For a new project, provide the wastewater source, current process, daily flow, foam location, temperature, pH and any existing defoamer information to support a more relevant recommendation.
