Jungkwang Aqua, Inc. - Decolorant, AQUA#501MC

Product Introduction

AQUA#501MC
Material Safety Data Sheet
Test Procedure

AQUA#501MC is a color removing reagent made from a kind of cationic polymer having an excellent bonding capacity for a wide variety of anions. Contaminants having anions in water are bonded strongly to the positively charged groups of AQUA#501MC, forming insoluble complexes and precipitate. Colors and surfactants in effluents from dyestuff or food industries can be removed efficiently by this reagent, leading to reduction of COD and SS.

Specification

Appearance: Colorless liquid
Specific Gravity : 1.20 - 1.30 (25°C)
Viscosity: 85 - 140 cps
pH: 5.5 - 6.0
Colloid Equivalent: 4.7 - 5.5 meq/g

Dosage

It is recommended to determine the appropriate level by means of laboratory “Jar Test”.
Suggested dosage levels are as follows:
Industrial Wastewater Treatment: 100 - 300 ppm
Domestic Sewage Treatment: 50 -80 ppm

Test Result

Test result of effluent from a dyestuff with 200 ppm of AQUA#501MC is as follows.

Test Item	Before Treatment	After Treatment
Color	430	27
COD	276 mg/l	84 mg/l
SS	31 mg/l	8 mg/l

Handling and Storage

AQUA#501MC solution should be made-down and stored in stainless steel, FRP or plastic vessels . Iron and aluminum components should be avoided. AQUA#501MC will remain stable for two or more years, provided it is stored in a cool, dry environment.

Toxicity

Spills of AQUA#501MC are slippery. This solution can be treated with an absorbent material , then collected for subsequent legal disposal. Precautions should be taken to prevent inhalation, ingestion or contact with skin or eyes. Observing basic industrial hygiene precautions should prevent any health or safety hazard.
See Material Safety Data Sheet for further information.

Test Procedure for AQUA#501MC

Step	Procedure
1.	Fill 500 ml graduated beaker with 300 ml wastewater to be treated.
2.	Add 200-300 ppm of AQUA#501MC and stir on rapid mix(100 - 150 rpm) for more than 5 minutes.
3.	Check pH.
4.	Adjust pH to 6.5 - 7.5 with NaOH (50% solution) or H₂SO₄ (20% solution).
5.	Add 2 - 3 ppm flocculant and stir 30 - 60 seconds.
6.	Reduce stirrer to slow speed(20 - 50 rpm) for 2 -3 minutes until large floc develops.
7.	Stop the stirrer and allow sample to settle for at least 5 minutes.
	This floc can float to the top or fall to the bottom
	If floc does not develop, add additional coagulant such as AQUA#501MH or flocculant.
8.	Test water for color, COD, BOD, SS or other parameters.
9.	Record data on appropriate form or spreadsheet.
* Repeat test at lower or higher injection rate of AQUA#501MCto determine the most optimum treatment for your application.
