COD Remover

COD Remover

Cod remover is a new type of chemical agent specially developed for the difficult removal of SS COD in wastewater of various industries. It has obvious effect on the removal of COD. When used with other products, the effect is better. The COD is stable and can meet the national discharge standard. It is suitable for the treatment of any cod wastewater.

Characteristic

1. It has good selective adsorption on insoluble substances causing excessive cod; 2. It has a good degradation and removal effect on the dissolved substances causing excessive cod; 3. Non toxic and side effects on microorganisms in biochemical system;

Action mechanism

Cod remover removes organic matter in wastewater through adsorption, chelation, flocculation and sedimentation, and precipitates and separates it

Scope of application

(1) Purification and treatment of urban domestic sewage

(2) It is applicable to all kinds of industrial wastewater, including ink, packaging and printing, auto parts, machinery, painting, surface treatment, coating, paint, electroplating, papermaking, food, printing and dyeing, bleaching and dyeing, tanning and other wastewater treatment processes;

Application characteristics

1. Excellent coagulation performance, dense alum and fast settlement speed;

2. Excellent water purification effect, good water quality, no harmful substances such as chlorine and heavy metal ions, and no water phase transfer of iron ions, non-toxic, harmless, safe and reliable.

3. The effects of turbidity removal, decolorization, deoiling, dehydration, sterilization, deodorization, algae removal, COD, BOD and heavy metal ions in water are remarkable.

4. Adapt to the wide range of pH value of water body, which is 4-11, and the optimal range of pH value is 6-9. After purification, the variation range of pH value and total alkalinity of raw water is small, and the corrosion to treatment equipment is small;

5. The purification effect of micro polluted, algae containing, low temperature and low turbidity raw water is remarkable, especially for high turbidity raw water.

Low dosage, 50% - 6% less treatment cost.

Usage method

When in use, the product can be directly added and pumped to the reaction tank, callback tank or discharge port.

The applicable pH value range is wide (4 ~ 11), and the dosage is about 20 ~ 500ppm. The dosage varies according to the refractory COD content in the wastewater (i.e. the COD content at the outlet after the current treatment). The specific dosage is generally determined by experiment.

During the experiment, take a certain amount of wastewater (such as callback pool water and drainage water), add an appropriate amount of COD remover, stir for 15 seconds, measure the COD value and determine the dosage.

The reaction speed is fast, so it can be directly added at the discharge port.
