Water is the source of life, and our lives cannot do without it. With the development of the economy, modern society has increasingly high requirements for environmental protection. In industries such as papermaking, aquaculture, and electroplating, wastewater and sewage often encounter foaming problems. How to solve the problem of foam in sewage and wastewater treatment? Chemi Tech defoamer manufacturer reveals the answer to defoaming and defoaming of water treatment defoamers through experimental cases.
Customer background:
A certain environmental protection technology Co., Ltd. in Hubei Province encountered foaming problems in the treatment of sewage from a biochemical tank. They found Chemi Tech through the internet and sent samples, hoping to find suitable water treatment defoamers through our experiments.
Customer homework process:
In biochemical water treatment, microorganisms including bacteria, fungi, algae, and protozoa are used to oxidize and decompose harmful substances in water into harmless substances. These microorganisms can survive in water containing toxins and use these toxins as nutrients for reproduction, thus transforming toxins into new substances that are harmless to humans.
An important step in biochemical treatment is aeration, which involves mechanical stirring and blowing in air to ensure sufficient contact between sewage and air, in order to maintain sufficient dissolved oxygen in the water and provide suitable conditions for microbial activity. However, foam will be produced in the process of aeration mixing, and the thick foam layer will seal the liquid surface, affecting dissolved oxygen, reducing the efficiency of the aeration device, and extending the treatment cycle.
Foam will also appear in the sewage movement containing protein, polysaccharide and saponin. During operation, a large number of filamentous bacteria and actinomycetes grow in the water body, which is easy to produce a large number of foam. The foam is mostly yellow brown, which is difficult to treat;
Foaming caused by production: foam will also appear in a large number of surfactants in the wastewater when the production line is washing the tank or when it is a dioxygen tank;
If the sewage plant conducts nitrification reaction, denitrification will occur in the sedimentation tank or the place with insufficient aeration, and bubbles such as nitrogen will be generated, which will drive part of the sludge to float up to foam.
Customer additive usage:
The water treatment defoamer developed by Chemi Tech defoamer manufacturer is made of polyether lipophilic products through special processes, and is an efficient defoamer specially developed for various biological water treatment systems. The characteristics are: fast defoaming speed, long foam suppression time, high efficiency, low dosage, especially no side effects on various aquatic fungi, no damage to the membrane, and environmental protection.
Customer maintenance and product improvement:
Customer maintenance:
In the subsequent supply process, the customer hopes that our company can provide technical support and frequently dispatch technicians to the factory to track trial production. The preliminary plan is to dispatch professional technical personnel to the on-site factory to track trial production in the early stage, with a time period of 1-3 days, to ensure that customers have no problems using it; We will dispatch technical personnel irregularly in the later stage to track the customer's usage on site for one morning, so that the customer can rest assured.
Product improvement:
At present, customers are generally satisfied with the third batch of water treatment defoamers, but they also hope to improve the effectiveness to the highest extent while maintaining the same unit price, reducing the amount used and lowering costs. We will adjust and improve based on the performance of the third batch of supplied products to meet customer requirements.
summary
Chemi Tech defoamer manufacturer not only provides defoamer research and development, customization, but also offers raw materials, formulas, and production. As a one-stop defoamer manufacturer, Chemi Tech can meet your various needs.
