During industrial cleaning processes, wastewater systems often generate large amounts of stubborn foam. This foam not only overflows from tanks and pollutes the workshop environment, but also reduces wastewater treatment efficiency and increases subsequent treatment costs. Foam covering the liquid surface hinders oxygen exchange and chemical mixing, leading to reduced cleaning effectiveness and even causing equipment pumping failures. The market urgently needs a dedicated additive that can defoam quickly and durably without affecting the cleaning process.
To address the above pain points, the Chemi Tech R&D team developed a series of industrial cleaning wastewater defoamers. This product uses specially modified polysiloxane and synergistic components, and can rapidly penetrate the foam film and reduce surface tension to achieve instantaneous defoaming and durable foam suppression. Its features include: resistance to high temperatures and to acids and alkalis, remaining stable over a wide pH and temperature range; good compatibility that does not affect the main functions of the cleaning agent; and significant results at low dosage, making it economical and practical.
The specific solution is implemented in three steps. First, carry out a small-scale trial evaluation of wastewater samples and, based on foam characteristics, water quality, and process conditions, recommend a matching defoamer model and initial dosage ratio. Second, select a suitable dosing point in the production system, usually recommended at the source of foam generation or at the circulating return water, using continuous dripping or intermittent injection. Finally, by monitoring foam height and treatment efficiency on site, fine-tune the dosage until a stable, foam-free state is reached, and establish a long-term maintenance plan.
We once helped a metal processing company in East China deal with a wastewater foam problem on its alkaline cleaning line. The company had been using an ordinary additive, and the foam kept overflowing, affecting workshop safety and compliance with discharge standards. After adopting the Chemi Tech custom defoamer and adding it at a ratio of 0.05%-0.1%, the foam rapidly dissipated within 30 seconds, and the foam-suppressing effect lasted throughout the entire cleaning cycle. The wastewater settling speed increased, the frequency of filter bag replacement decreased, and the overall treatment cost was saved by about 15%. The company reported that the system ran smoothly and the environment improved markedly.
Choosing Chemi Tech defoamers means gaining professional technical support and reliable product performance. We can provide sample testing and optimization plans based on your specific working conditions, helping you bid farewell to foam troubles for good and ensuring a smooth and efficient cleaning process.
