| COAGULANTS |
|
Aluminum Sulphate
|
Aluminum Sulphate, one of the two most used coagulants in wastewater treatment systems, is a highly efficient treatment chemical. After its application, it does not cause visual pollution in process mechanics compared to iron sulfate and iron (III) chloride, making it aesthetically preferred.
Working condition: 5.5 - 7.8 pH Quantity: Sold in 25 kg and 50 kg sacks.
|
Al2(SO4)3
|
|
Iron (III) chloride
|
It is a good coagulant, generally used as a 40% solution. It is dark brown in colour and has a corrosive effect since its solution in water is acidic. Therefore, it should be stored in acid-resistant (plastic, etc.) drums.
Working condition: pH 6 - 9 Quantity: Sold in 75 and 90 kg drums.
|
FeCl3
|
|
Iron sulfate
|
In the coagulant stage, it is one of the two most commonly used chemicals. This is a treatment chemical with high yields. Depending on the quality of the discharged wastewater in our country, 85% of wastewater treatment plants can yield efficient results with iron sulfate.
Working condition: pH 5-10
|
FeSO4
|
|
Poly Aluminum Chloride(PAC)
|
It has a coagulant-increasing effect as an auxiliary product of coagulant. It is a type of coagulant that is easily soluble in water and the pH of its 1% solution is between 3.5 and 4.5. It should be stored in acid-resistant materials since it shows corrosive properties in the solution.
Quantity: Sold in 25 kg packages.

| FLOCCULENTS |
|
Anionic Polyelectrolyte
|
It is used to provide flocculation by acting like tangles formed after coagulation. There is no abrasive.
Quantity: Sold in 25 kg packages.
|
Anyonik Poli
|
|
Cationic Polyelectrolyte
|
It is used in excess activated sludge of biological treatment plants. Cationic polyelectrolyte is added to the sludge line to dewater the sludge during the pumping of the excess activated sludge from the settling pool to the filter press or belt press.
Quantity: Sold in 25 kg packages.
|
Katyonik Poli
|
| pH ADJUSTERS |
| Hydrochloric acid |
It is used to reduce the pH to the desired range in order to provide the coagulant with high efficiency in wastewater with a high pH value. Also ensures that the wastewater is reduced to the appropriate pH so that bacteria are not affected in biological pool facilities.
It is sold in 75 kg drums in 33% liquid form.
|
HCl
|
|
Calcitic
|
It is used to raise the pH of acidic wastewater. It is an important treatment chemical as it will adversely affect flock formation and precipitation when the appropriate pH operating range cannot be reached.
|
CaO
|
| Caustic (NaOH) |
It acts as a pH increase. It is released by reacting with water. It acts as a good pH increaser in low pH wastewater. It does not cause occasional blockage in dosing pumps. Therefore, its use is advantageous.
|
NaOH
|
|
Sulfuric acid
|
It is a chemical used as a pH reducer. It is used fort he same purpose as hyrocloric asid with wastewater treatment. From working while sulfuric acid, you should provide personal protection that needs.
|
H2SO4
|
| OTHER |
|
Sodium Hypochlorite
|
It used to disinfectant in the discharge of wastewater treatment to the receiving environment. Sodium hypochlorite is used especially in biological wastewater treatment plants and urban drinking water plants against pathogens that may remain in the water.
Packing Quantity: Sold in 75 kg drums.
|
NaClO
|
|
Sodium metabisulphite
|
It is used in the purification of Chromium +6 in industrial wastewater.
Sodium metabisulfite reacts with acidic solutions and water, causing the formation of sulfur dioxide gas, making it difficult to breathe. For this reason, it is recommended to work with this substance after taking the necessary precautions.
