Sunfloc Anionic Polyelectrolyte for Foundry Sand Water in Coimbatore
Foundries and pump makers around Coimbatore recirculate sand and quench water. Anionic polyacrylamide (PAM) clears it in minutes at the pit inlet.
Sand, clay and scale
Sand-reclamation and quench water in Coimbatore's foundries carries fine sand, clay binder and iron scale. Left alone, it settles slowly and wears pumps and nozzles.
Anionic HQ dosed at the settling-pit inlet gives clear water within minutes and a tight sludge that is simple to clear out.

Sizing the dose for a pit
Rough numbers for a 1,200 m³/day plant: 0.8 mg/L means 0.96 kg a day, or about 960 litres of 0.1% solution run over 16 hours.
Foundry water is steady between pours, so once the dose is found it rarely needs to move far. Anionic MQ in a 10 kg bag is often enough for a shop of this size.
Siruvani water and the monsoon
The Siruvani and Pilloor supplies are normally clear, which keeps raw-water doses low for most of the year. When the south-west monsoon turns the supply turbid, the dose has to rise quickly, and daily jar tests during those weeks prevent poor clarifier performance. A consignment from Chennai usually lands in one to two days.
A worked example for a foundry sand-washing pit
Take a foundry sand-washing pit: 250 m³ a day at 0.3 mg/L is 0.075 kg of Sunfloc Anionic a day, about 2.25 kg a month. Made up at 0.1%, that is 75 litres of solution a day. These figures are illustrative; a jar test on your own effluent sets the real dose.
Dose at the pit inlet, where the turbulence is, rather than at the outlet weir, and re-check after a change of sand binder.
Anionic Sunfloc questions from Coimbatore
Is anionic the right charge for foundry water?
Sand, clay and iron scale are mineral solids, which anionic grades settle well.
How fast does it work?
At the pit inlet, a correct dose clears foundry water within minutes. Confirm the dose on your own water by jar test.
Does it work on cutting-fluid emulsions?
Not before the emulsion is split. After that, a cationic grade or SunMac helps; see SunMac for Coimbatore.
