Wastewater Treatment and Defoamers - Lankem
Defoamers. The types of defoamers that are utilised in wastewater plants are varied, from silicone based, mineral-oil based and polyalkylene glycol type. As mentioned earlier defoamers containing hydrophobic properties can worsen the foaming issue in bacteria based ones. Lankem is actively developing a series of bio-based ones for these types
PMC OUVRIE has developed a wide range of defoamers — esterified polyols, aqueous emulsions of fatty alcohols and silicone-based products — to treat foaming in the oxygenation basin. These defoamers have been specially formulated to not interfere with dissolved oxygen contain.
Defoamers for Wastewater Treatment - PMC Ouvrie
PMC Ouvrie has defoamers’ family that control foam and entrained air in wastewater systems. PMC Ouvrie’s defoamers collapse and break down existing foam. Additionally, they remain on the water’s surface to prevent future foam formation. The causes of foam in a wastewater treatment plant are varied.
“The presence of foam in effluent from wastewater treatment plants can prompt complaints from local people and authorities, even if the foam is harmless to humans and the environment. Likewise, obnoxious smells, e.g. from foul-smelling hydrogen sulphide (H2S), can cause more dissatisfaction among neighbours.”
DeFoam 3000 - Fast-Acting Defoamer, Wastewater System-Safe
Wastewater Defoamer Designed for Biological Plants DeFoam 3000 is a 100% concentrated defoamer, formulated to rapidly deflate foam by creating a monomolecular film. This film spreads across the water surface, quickly collapsing foam.
See how Aries helped a paper mill using defoamers to treat water and wastewater. Learn why we had the perfect solution for this paper mill's wastewater solution, and what the end results were. Remember, the Aries defoamer is FDA compliant.

Foam. Foam occurs when gas becomes entrapped at the surface of or within a liquid caused by biologically, chemically or mechanically (surface aeration, mixers, diffused air). The most commons two types of foam in wastewater are biological and chemical/surfactant induced foam.
KNOCK DOWN ll: Silicone Defoamer for Wastewater
SILICONE DEFOAMER FOR WASTEWATER TREATMENT KNOCK DOWN II is an effective silicone defoamer used in a wide range of wastewater streams to control foam. KNOCK DOWN II reduces the surface tension of the wastewater thereby reducing the tendency to create foam. It is used in wastewater treatment plants to control excessive foam during processing.
Antispumin defoamers are a family of proprietary products that control foam and entrained air in municipal wastewater systems. Antispumin defoamers collapse and break down existing foam. Additionally, they remain on the water’s surface to prevent future foam formation. Antispumin defoamers provide benefits including:
Knowledge points of paper mill waste water treatment defoamer
Knowledge points of paper mill waste water treatment defoamer Waste water discharge from paper mills has always been a serious problem.Waste water treatment is also a concern of everyone. Wastewater treatment uses a number of physical, chemical and biological methods to treat wastewater.This can achieve the purpose of purifying water resources
This defoamer is designed specially for papermaking industry, which aims at the foaming character of wastewater treatment technique. It can efficiently control the overflowing problem of paper pulp and improve the paper quality. Due to it is non-toxic, so it’s more conducive to production safety and the white water discharging.

- What should be included in a water quality programme?
- Such programmes should normally include: water hygiene awareness raising; basic technical training and technology transfer in drinking-water supply and management; consideration of and approaches to overcoming sociocultural barriers to acceptance of water quality interventions;
