SunMac – Cationic Polymer Supplier in Kochi
Seafood effluent from Aroor and the port is rich in protein, fat and blood. SunMac is a liquid polymer that many DAF operators find easy to dose.
Fat, protein and blood
Washing, peeling and cleaning of export shrimp and fish take a great deal of water. What drains off is full of protein, fat and blood, and it starts to smell fast. Dissolved air flotation (DAF) is a common way to skim off fats and solids ahead of the biological stage.
With a coagulant first and then a cationic polymer, fat and protein form flocs that cling to the rising air bubbles.
Documents for SunMac SC04
A liquid for the DAF
SunMac SC04 is a liquid option for DAF dosing, since it goes to the pump as supplied. Cationic Sunfloc grades are the powder alternative. A jar test tells you which gives the better float and the cleaner subnatant.
On the chemical side, the Eloor–Edayar belt treats oily wastewater with separators and flotation first.
Monsoon and export audits
Kochi receives very heavy south-west monsoon rain, and raw water turbidity can rise many times in a day. Place the bigger orders ahead of the monsoon, since delays on the road are likelier once it breaks. Seafood exporters face customer audits, so keep documents for each product on file. See the Kochi guide. About two days by road from Chennai.
SunMac questions from Kochi
Is SunMac only for DAF?
No. It is a charge-neutralising liquid for clarifiers and flotation units alike.
How does humidity affect storage?
Keep drums sealed. Opened powder bags cake in Kerala's humidity, while a sealed liquid drum is less affected.
How long does a drum take to arrive?
About two days by road via Salem and Palakkad on NH 544.
Reading the flotation unit
In a DAF the dose and the air supply work together. Change one at a time and write both down.
