Different wastewater with different foam agent

Sewage treatment of defoaming agent in use in the process of dispersing uniformly, it relies on nonionic medium will dilute the bubble, and a wide range of bubble were excluded, is a very practical industrial additives.
The choice of wastewater treatment and eliminating agent is a skill:
1, clear their own industry: sewage treatment of fire foam agent can not be generalized, but according to the selection of the industry, such as textile printing and dyeing industry might choose alkali resistance of foaming agent can be a very good solve bubble.
2, a clear bubble elimination agent added point: the general consumer bubble can be divided into the point of discharge, aeration, microbial wastewater treatment. The performance requirements of the same point for the different of the bubble is not the same. The discharge port is required to have a fast aeration agent, while the aeration tank is required to have good performance.
3, addition: adding amount of sewage treatment is a luxurious, laboratory recommended dosage general in 50 to 100 ppm, of course, specific to according to the field of water treatment and water pollution degree to add.
4, municipal sewage treatment: because the sewage contains a large number of domestic oil, so try not to choose silicone defoaming agent, can consider choose polyether type defoaming agent, defoaming effect is better.
5, the general type of silicone defoaming agent for sewage treatment effect significantly, but need to pay attention to is, when is sewage circulation system of reverse osmosis membrane in wastewater treatment is not used silicone de foaming agent of, because part of the composition of silicone will have certain influence on the osmotic membrane, can only be good to the defoaming effect, also affect the production of normal were. The polyether type defoaming agent is more suitable, for example, Gloucestershire XST-5399 effect is great.
There is a few pieces of products in sewage treatment of customers that have been confirmed in the, such as XST-1038; XST-3230; XST-5130; XST-5399; XST-9001 and so on Gloucestershire.
XST-1038 by moderately hydrophobic polysiloxane for defoaming active substance was prepared by emulsion type defoaming agent, and the use of system has good compatibility, and has better quick breaking foam performance.
A high temperature resistant defoaming agent, XST-3230, in strong acid, strong alkaline medium and strong mechanical stirring, cutting environment to maintain the excellent fire suppression foam performance.
XST-5130 consist of an anti bubble good performance of special polyether and defoaming excellent properties of polysiloxane by reasonable collocation of preparation of a compound emulsion defoaming agent, at lower concentrations can keep good bubble breaking and long time of antifoam. It can also be used in compatibility requirements of high field.
XST-5399 for a 100% content of the oil type of oil - type foam agent. Its dispersed phase and continuous phase have excellent performance, so it has good activity at low temperature and high temperature. In a wide range of pH value and temperature, the foam control for various industrial water phase system is used.
XST-9001 solid powder defoaming agent is mainly for water system of hydrophilic polymeric material foaming characteristics, using for the antifoaming activity as antifoaming ingredient, to environment friendly water soluble or water dispersed type solid powder as carrier was prepared. In the aqueous polymer foaming system has rapid fire bubble bubble breaking and lasting inhibiting foam performance, the defoaming agent suitable for the use of temperature are widely using environment in acid resistance, alkali resistance, salt resistance, good resistance to shear performance. Chemical stability, non-toxic, non corrosive, green.
Eliminate the bubble, so that people who need it love and hate. Love it, because the production process is indispensable; hate it, because it is impossible to have a perfect universal type of anti foam agent.
At present, there are a lot of good anti foaming agent in the market, some domestic independent production of the quality can be comparable to the imported.
For the best.
