Biological Bacteria Powder for Removing Phosphorus in Sewage

The most common types of phosphorus in sewage are phosphates, polyphosphates and organic phosphorus.

1) The phosphorus content of domestic wastewater is generally around 10 to 15 mg/L, of which 70% is soluble;

2) About 90% of phosphorus exists in the form of phosphate.

Principle of biological phosphorus removal process

1) Using a kind of bacteria called phosphorus accumulating bacteria (also known as phosphorus removing bacteria, phosphorus bacteria, etc.) can fully release the polymerized phosphate in its cells under anaerobic conditions, this process is called anaerobic phosphorus release;

2) Under aerobic conditions, it can absorb phosphorus from water beyond its physiological needs. This process is called aerobic phosphorus absorption;

3) And convert it into polymerized phosphate in the cell body, thus forming phosphorus-rich biological sludge, and discharge this phosphorus-rich sludge from the system through precipitation to achieve the effect of phosphorus removal from wastewater.

It should be noted that in the process of anaerobic phosphorus release and aerobic phosphorus absorption, the phosphorus removal effect is easily affected by factors such as dissolved oxygen, pH, temperature, sludge age, BOD load and organic matter properties. Unable to meet water standards.

Therefore, many biological phosphorus removal processes are used. In order to ensure that the effluent reaches the standard, Phosphorus Removal Bacteria are used, which can also be used as flocculants while removing phosphorus.

For medium and low concentrations of phosphorus in sewage, directly adding phosphorus-removing bacteria can not only completely remove phosphorus, but also control the treatment cost, effectively solve the problem of phosphorus removal in sewage, and maximize the value of phosphorus removal in sewage.
